Kapadiya J.K., Mathukia R.K., Gohil B.S. Scheduling of Nitrogen and Potassium in Wheat (Triticum aestivum L.)

Wheat is the second most important staple food after rice consumed by 65% of the population in India. Fertilizer plays a leading role in increasing crop production by almost 41%. Among the primary nutrients, nitrogen plays an important role in plant metabolism by virtue of being an essential constituent of structural component of the cell and many diverse type of metabolically active compounds. It is also a constituent of chlorophyll, which is important for the harvest of solar energy. Nitrogen is liable to lost through leaching, volatilization and run off during crop period. Further, crop requires N throughout the growth period. Potassium plays an essential role in plant growth and metabolism. It activates enzymes, maintains tissue turgor pressure, regulates stomata closing and balances the charge of anions. When applied in soil, it aggregates with clay particles so slowly release in soil. So, split application of nitrogen and potassium is seems very important and essential to be studied for wheat crop.

Patil Somanagouda B Tillage and Nutrient Management in Groundnut

Groundnut (Arachis hypogaea L.) also known as peanut and earthnut, is an important oilseed crop largely grown by resource poor smallholder farmers under rainfed conditions. These farmers employ different tillage practices in the production of the crop. Many farmers perform tillage operations without being aware of the effect of these operations on soil physical properties and crop responses. It is carried out mainly to loosen the upper layer of soil, to mix the soil with fertilizer and organic residues, to control weeds, and to create a suitable seedbed for germination and plant growth. The theme of nutrient management in integrated way for increasing the soil fertility is gaining ground throughout the world in recent years due to high cost of fertilizer and reduced availability of organic manures. Modern tillage and integrated nutrient management practices may affect soil fertility and productivity of groundnut due to different soil conditions created and fulfills the nutrient requirement of crop. The book contains the information on the effect of tillage and integrated nutrient management practices on soil fertility and productivity of groundnut under rainfed conditions.

Muthuri Jacinta Soil Fertility and Yield of Soybeans

Soybean is an important crop in the world due to its supply of proteins and oil. In spite of its importance as a source of protein and oil, its production is way below potential. Declining soil fertility and high fertilizer costs are major limitations to crop production in developing countries due to reduction in farm sizes caused by increased human population. Reduced dependence on inorganic fertilizer nitrogen and adopting farming practices that favour more economically viable and environmentally prudent nitrogen fixation will benefit both agriculture and the environment. Biological materials may offer a solution in alleviating soil fertility problems and hence increase in crop production. Farm derived sources such as crop residue, compost, manure and household waste can be used by farmers in the management of soil fertility. Animal manure and compost are beneficial in soils because they can increase the water holding capacity and cation exchange capacity. This book assesses the effect of soil amendment with manure (poultry and farmyard) on the plant growth, nodulation and yield respectively as compared with inorganic fertilizer.

Suleiman Usman The basic soil problems and possible solutions in agriculture

Document from the year 2011 in the subject Agrarian Studies, University of Greenwich, language: English, abstract: It is widely recognised that environmental problems such as soil degradation (erosion and desertification) affects many agricultural lands globally. These problems have caused soil quality decline, crop yield reduction, economic crisis, poverty, unemployment, and rural urban migration. Soil management practices are considered as the most vital and sustainable possible solution to control soil erosion and desertification. This management include use of organic manure, crop rotation, use of cover crop, intercropping, planting shelter belt and afforestation, provision of water ways, good surface drainage system, restoration of rangeland, regeneration and secondary forest, and political changes.

Document from the year 2010 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, Dresden Technical University (Institute of Soil Science and Site Ecology), course: -, language: English, abstract: Soil properties are not only influenced by geographical factors, such as parent material, location and latitude. Often differences in land uses (forest, rubber plantation, paddy field, bare land) are known to have specific effects on soil properties. In the context of the project Living Landscapes China (LILAC) these effects were evaluated and the characteristics of soil types under changing conditions in two transects (altitude and parent material in transect 1, land uses in transect 2) in the Naban River Watershed National Nature Reserve were classified. We used field investigations to classify the soil types, as well as laboratory analyses to quantify specific characteristics in samples, taken from the profiles. Soil physical (bulk density, water content, texture) and chemical parameters (total contents of carbon, nitrogen and macro nutrients, ECEC) were investigated. While differences in altitude did not seem to have profound influences on the soils, effects of land uses were pronounced especially in the first 10 to 20 cm of soil profiles. Soils under forests contain between 1.3 % - 2 % SOC and 0.15 % - 0.17 % TN in the Ah horizon. With contents of 1.2 % SOC and 0.11 % TN (Ah horizon) the profile under agricultural use (paddy rice) clearly contains less S...

Yemisrach Tadesse, Bizuayehu Tesfaye (PhD) Response of Taro to Applied Nitrogen and Potassium Fertilizer Levels

Taro (Colocasia esculenta L.) is one of the major staple root crops in different countries of the world.However, the yield potential is seldom realized, and among the yield limiting factors, soil fertility is one of the major factor affecting the yield of the crop. Thus, this book gives research result on 'Response Taro to Applied N and K Fertilizer Levels. Two types of fertilizers at different levels, i.e. K (0, 75, 150 and 225 kg ha-1) and N (0, 50, 100, 150 and 200 kg ha-1), were combined in factorial for the experimental study. The response of taro to N and K levels was assessed by examining growth and yield parameters. The result revealed that K had no significant effect on the growth and yield of taro, except for the corm dry weight. But N had significantly affected both the growth and yield of taro. The maximum yield (60.96 t ha-1) was obtained by application of 150 kg N ha-1. Economic analysis showed that the highest net benefit was obtained in treatment combination of 75 kg K ha-1 with 150 kg N ha-1. However, the marginal rate of return analysis was optimum when 100 kg N ha-1 was applied. Thus, 100 kg N ha-1 was found optimum for taro production based on this experiment.

Intercropping is experienced by preponderance of farmers in many regions of the world. Intercropping has since long been used as mean to cover the risk of failure of base crop and it can pilot to boost food supply without retreating the sustainability of soil. This system of cropping suppresses weeds, reduces pest disease infestation, gives yield advantage and there is stable yield over time. Crop fertilizer needs can be met with the addition of an organic fertilizer, which is suitable for enhancing crop yields on sustained basis and cost effective too. The use of legumes as an intercrop can serve a potential source of organic fertilizer. It can be used as a supplement source of nutrition especially that of nitrogen. It is an economical way of food production as one input such as N from legume can be applied once and used by all the crop components in the farm thereby saving time for the farmer. Thus present project will be helpful to farmers in order to augment the crop yield and sustain the soil fertility, identify an effective and low cost fertilizer level technique for maize and substitute N-fertilizer with leguminous crops as an organic source.

Soil can be defined as the space time continuum forming the upper part of the earth's crust. It is a natural body comprised of solid, liquid and gases that occur on the land surface. Joffe (1949) defined soil as a natural body differentiated into horizons of mineral and organic constituents usually unconsolidated of variable depth, which differs from the parent material below in morphology, physical properties and constitution, chemical properties and composition, and biological characteristics. Soil is one of the most fundamental resources for sustainability and survival. It is one of the most important assets to protect and pass on to future generations.Soil contamination due to anthropogenic and natural sources is increasing day by day because of increasing population, industrialization, and urbanization. Soil is the receptor of many contaminants from various sources. Contamination decreases the quality of the soil and adversely affects soil organisms.For this study, soil samples from thirteen locations contaminated from agricultural, industrial, and organic sources spread over the districts of Alappuzha and Kottayam in Kerala in the south west coast area of India were analyzed to study the changes in soil characteristics and its influence on soil microbial communities and their activities.

David Kagima Variable Rate Herbicide Application GPS, GIS, and VRT Technology

It is well established that preemergence herbicide activity is influenced by soil type, and recommended rates for most soil-applied herbicides are adjusted to soil type. Current technology allows application rates to be adjusted on the go (VRA), adjusting the rate as soil type changes in a field. Most applicators offering this service base herbicide rates on soil organic matter content. However, several other factors influence herbicide activity, most importantly weed density and environment. This research is to determine which of these factors is most important in determining the optimum herbicide rate, and the economic benefit of VRA to the grower. The objective of this study is to determine the relative contribution of soil type, weed density and environmental factors on herbicide effectiveness.

Saman Daneshmand, Bujang B. K. Huat Improving Soil Properties to Prevent Surficial Slope Failure

Many hill slope areas are vulnerable to soil erosion and shallow slope failures due to intense and frequent rainfall of tropical climate.In this study, Laboratory tests were performed on natural soil and soil mixed with deferent percentage of lime to improve soil properties and resistance against slope failure.When lime mixed with in-situ soil, it reduces swelling potential and shrinkage hence inhibit formation of cracks and also reduce soil's dispersibility therefore, reduce erosion possibility. Soil mixed with lime has lower permeability thus, it enhances capillary barrier effects and limits rainfall infiltration into the soil.Results show that optimum lime content to be used in the mix design is 7% by dry unit weight of soil. A two dimensional finite element model of slope was used to evaluate performance of the optimum lime-soil mixed as capillary barrier. The analysis revealed that the optimum thickness of slope cover system in capillary barrier is 30cm. Finding of this study, would contribute to a practical method of slope stabilisation and to display optimum slope cover thickness in capillary barrier effects.

Despite the research effort put into controlling pathogens, pests and parasitic plants, crop losses are still a regular feature of agriculture worldwide. This makes it important to manage the crop appropriately in order to maximise yield. Understanding the relationship between the occurrence and severity of attack, and the resulting yield loss, is an important step towards improved crop protection. Linked to this, is the need to better understand the mechanisms responsible for reductions in growth and yield in affected crops. Physiological Responses of Plants to Attack is unique because it deals with the effects of different attackers – pathogens, herbivores, and parasitic plants, on host processes involved in growth, reproduction, and yield. Coverage includes effects on photosynthesis, partitioning of carbohydrates, water and nutrient relations, and changes in plant growth hormones. Far from being simply a consequence of attack, the alterations in primary metabolism reflect a more dynamic and complex interaction between plant and attacker, sometimes involving re-programming of plant metabolism by the attacker. Physiological Responses of Plants to Attack is written and designed for use by senior undergraduates and postgraduates studying agricultural sciences, applied entomology, crop protection, plant pathology and plant sciences. Biological and agricultural research scientists in the agrochemical and crop protection industries, and in academia, will find much of use in this book. All libraries in universities and research establishments where biological and agricultural sciences are studied and taught should have copies of this exciting book on their shelves

Miah Sohag Shifting Cultivation Effects on Soil Environment

Alike all other hill dwellers of the world, shifting cultivation, commonly known as 'Jhum', is the traditional agronomic practice among the indigenous people of hilly tracts of Bangladesh. This age old cultivation system affects, mainly negatively, on soil environment and worsens the upland watershed health. For investigating this hypothesis, a study was conducted at three pair sites viz: Simina Para, Kark Mohajon Para and At- mile area of Sadar upazila under Khagarachari district to determine the effects of shifting cultivation on soil environment. Both soil physico-chemical properties and the biochemical and biological properties of soil microbes were studied. The differences in microbial population count and population composition may not be universal for all shifting cultivation sites; however, it explains the unavoidability in the variations of the biological and biochemical characteristics of soil microflora in shifting cultivated areas and emphasizes the necessity of taking this factor into consideration in management of soils in fellow lands after shifting cultivation.

Girmay Daniel, Kebede Fassil, Zenebe Amanuel Land Use Change Effect on Soil Health

Estimates indicate that a majority of the earth's land has been seriously degraded. One of the key degradation problems is poor soil health, which has been identified as a key constraint in agricultural productivity and reducing rural poverty in many parts of the tropics, particularly in Sub-Saharan Africa. Ethiopia's economy is primarily based on agriculture. However, this sector is increasingly being confronted with a rapidly growing population, and this has resulted in land use/cover changes. The changes in land use disturbs ecosystem balance and lead to a significant change in the physical, chemical, and biological soil health thereby yield declines. Half of the Ethiopian highland arable lands are moderately to severely degrade. Tigray, the Northern region of Ethiopia, suffers from extreme land degradation and soil health deterioration. Agulae catchment, the study area which is found in Eastern Tigray also has similar problems. Since previous studies on factors affecting soil health depletion has not been made at a catchment level, this study was conducted to fill the existing knowledge gap on the effects of and use change on soil health and its implication on soil management.

Scientific Study from the year 2016 in the subject Agrarian Studies, , language: English, abstract: Jackfruit (Artocarpus heterophyllus) is commonly grown in home gardens of tropical and sub-tropical countries. The fruit contains high levels of carbohydrates, protein, starch, calcium and vitamins. The Artocarpus heterophyllus is believed indigenous to the Western Ghats of India. It is adapted only to the humid tropical and near tropical climate. The tree flourishes in rich deep soil of medium or open texture, sometimes on deep gravelly or laterite soil. In India they say that the tree grows tall and thin on sand, short thick on sandy land. Here the physical and chemical properties of soil from surrounding plots of different varieties of Arthocarpus heterophyllus have been analysed by using different technical methods and evaluating the effects of soil property on jackfruit nutritional quality. It was observed that there was a considerable difference in case of some minerals likes phosphorous, potassium, magnesium, zinc and manganese. Change in the soil pH also noticed. The pH also plays a major role in the sweetness of the jackfruit. The optimum pH of the amylase inside the jackfruit was found to be 6.2 to 6.8. The result shows that the soils that have higher pH have more sweet flakes. Proximate nutritional composition of the flake reveals the presence of protein, fat and fibre in a greater amount in some flake and these flakes were sweeter than the others. There was a much d...

Deka Gitimoni, Bhattacharyya Krishna Gopal Impacts of a Textile Mill on Water and Soil Quality

This work investigates the impacts of the effluents and other wastes of a Textile Mill on quality of soil and water in the surrounding areas. Some specific impacts on soil and water quality have been identified. For example, the soil was getting enriched with both ionic matter and hydrophobic organic matter, which had important consequences. The soil became enriched with the trace metals, As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, and Zn. The quality of the drinking water in and around the textile mill did reflect the changes in the physico-chemical quality of the soil. The water was characterized by considerable presence of the cations, Ca, Mg, Na and K, being compensated by comparative presence of the anions, Cl, NO3 and SO4. The toxic organic contaminant, phenol, was present in some of the drinking water sources. The water was contaminated with Mn, Ni, and Pb, and also fluoride. The rice crop grown in the study area had accumulated appreciable amounts of metals in them as seen from the analysis of rice grains and husks. Significantly, the husks were seen to be richer in the metals than the grains with one or two exceptions.

India is especially suitable for agricultural products, its vast plains containing alluvial soil with rich natural contents. The major economy of India is based on agricultural products. The green revolution in India brought high hopes for Indian farmers. Several new scientific information helped crop production to grow by leaps and bounds: the more researches, the more intricacies. Further knowledge of pests makes scientists consider several new solutions. The use of chemicals was immediately adopted to decimate the population of pests and, at first, good results were obtained. But later on, harmful effects of the pesticides became known. It was realized later on that the regular use of chemicals in pesticides is extremely dangerous for human health.Generally, chemical pesticides are used to curb the harmful effects of insects and pests. But the immediate gain of this process has an adverse effect on the environment in the long run. Regular use of chemicals leads to insecticide resistance. Then, biodiversity is distributed by pest resurgence and pesticide residues. So, the immediate gain of one generation creates serious problems for the next generation.To sustain agriculture towards its natural mode some new solutions are to be traced. The solution to reduce pesticides is present in the preference for biological management. Predators and parasitoids may be used as natural enemies.

Alam Md. Izhar, Das Ajay Kumar, Prasad Birendra Response of Nitrogen and PGRs on Cape-goosebery

Sixteen plant food nutrients are essential for proper crop development. Each is equally important to the plant, yet each is required in vastly different amounts. Primary (macro) nutrients are nitrogen, phosphorus, and potassium. They are the most frequently required so plants use large amounts for their growth and survival. As agriculture becomes more mechanized and science increases the possibilities for using inputs to enhance production, the role of PGRs becomes more vital. Plant growth regulators (PGRs) have been an important component in agricultural production even prior to the identification of plant hormones. PGRs are now used on worldwide on a diversity of crops each year. Most of these applications are confined to high-value horticultural commodities rather than field crops. This book includes informative visuals, such as tables of physical and physico - chemical parameters of Cape gooseberry, Nitrogen & PGRs and its effects on fruit crop. This book also helps those people, students, teachers and researcher who work on essential nutrient and plant growth regulators in Agriculture and Horticulture.

Singh Astha Studies on Bacterial Leaf Blight of Cotton (Xanthomonas axonopodis)

Bacterial Leaf Blight (BLB) of cotton is one of the most important diseases causing substantial losses to cotton crop in India. The disease is caused by Xanthomonas axonopodis pv malvacearum (Xam) which is a seed borne foliar pathogen of cotton. Several studies were conducted on the bacterial growth facilitators, varieties of cotton, efficacy of fungicides and antibiotics. Resistance for BLB was screened within 40 varieties, out of which 6 (Lohit, Shyamli, Acala 3080, LD 419, RG 8, CAD 4) were resistant and 10 were found to be moderately susceptible. Culture media studies were performed for the optimum growth of the pathogen, nutrient broth facilitated optimum growth of the bacterium followed by Muller Hinton agar. The efficacy of 12 fungicides was tested against the bacterium. Thiram, Mercuric chloride, Carbendazin with Mancozeb, Bavistin, Captan and Formaldehyde were found effective against Xam. Testing for efficacy of antibiotics implied that streptomycin and chloramphenicol gave optimum results.

Ahsan Rabbani Effect of Temperature on Swelling Pressure and Compressibility of Soil

Master's Thesis from the year 2018 in the subject Engineering - Geotechnology, grade: 9.36, National Institute of Technology, Rourkela, language: English, abstract: Construction of building on clay soil is highly risky due to its poor strength. Clayey soil creates many problems to the Geotechnical Engineers primarily because of repeated change of moisture content. Normally, these soils increase in size and swell when they absorb water and reduce in size and shrink when they become dry. Volume change in soil leads to distortions in the form of settlement due to contraction as a result of dryness or in the form of expansion due to swelling as a result of the absorption of water. There may be the need for soil treatment to improve the engineering properties of such soil. Compacted bentonite is often used as a buffer materials and for radioactive waste disposal system. A good understanding of the hydro-mechanical behavior of clay soil is essential to ensure safe disposal.The present study reports the results on the effects of temperature on swelling pressure and compressibility characteristics of soil. In this study, two different type of soils were used. One of them was a bentonite (liquid limit = 139%) procured from Bikaner, Rajasthan another one was Rourkela local soil (liquid limit = 35%). A new oedometer was designed and developed in-house to carry out consolidation and swelling pressure tests at a higher temperature. Swelling pressures tests on compacted bentonite speci...

Mubashir Aziz Experimental Study on Effects of Deterioration of Grains on Deformation and Strength Characteristics of Soils

Doctoral Thesis / Dissertation from the year 2010 in the subject Engineering - Geotechnology, , course: Civil Engineering, language: English, abstract: With growing infrastructure developments in hilly areas and due toeconomical constraints of using locally available rockfill materials for construction of embankments, practicing engineers must be acquainted with geotechnical response of non-conventional granular soils. These materials are most likely to disintegrate with time due to physical and chemical weathering. In general, the laboratory investigations on durability characteristics of such materials are only made through simple slaking tests. However, studies examining the effects of slaking-induced disintegration of soil grains on thegeotechnical engineering analysis and design parameters are rather limited. This is essentially due to the reason that the grains of standard laboratory sands are mostly durable and hence, the stress-strain response is considered to be unaffected by the presence of water.In order to explore the possible effects of deterioration of soil grains on static and dynamic properties of granular soils, a series of consolidated drained torsional shear tests on various crushed soft rocks were performed under saturated and dry conditions and compared with a well reported Toyoura silica sand consisting of durable grains. Due to the sensitivity of crushed rockfill todeteriorate upon water-submergence, test under dry conditions represented the response of...

Deborah A. Henady-Korba The Effects of Divorce on Children. A Mother-Son Perspective

In today’s society, divorce touches the lives of many families and children. In The Effects of Divorce on Children, author Deborah Henady-Korba explores the impact of divorce on young children, focusing on boys ages eight to twelve and the mother-son relationship.This critical literature review seeks to establish connections with divorce and issues related to adjustment including problem-solving skills, coping mechanisms, attachment and bonding, explanatory style, vulnerability, resilience, risk, and adjustment problems with behavioral and emotional outcomes. It addresses the following questions:• How do boys between the ages of eight and twelve in divorced families cope successfully? • What are their coping behaviors? • Is there a relationship between the effects of post-divorce adjustment on boys who are between eight and twelve years of age and their developmental stages leading to increased behavioral and emotional problems? • What are the effects of post-divorce adjustment on the mother-son relationship? The Effects of Divorce on Children shares the results of Henady-Korba’s Literature Review and makes a meaningful contribution to social change in today’s society, by offering a revised Diathesis-Stress Model incorporating protective and risk factors that lead to effective or ineffective coping skills and resiliency that may be applied in several areas of psychology.

Albert Howard An Agricultural Testament

Facsimile of 1940 Edition. An Agricultural Testament is Sir Albert Howard's best-known publication and remains one of the seminal works in the history of organic farming movement. The work focuses on the nature and management of soil fertility, and notably explores composting. At a time when modern, chemical-based industrialized agriculture was just beginning to radically alter food production, it advocated natural processes rather than man-made inputs as the superior approach to farming. It was first published in England in 1940. Since this book first appeared in 1940, it has been regarded as one of the most important contributions to the solution of soil rehabilitation problems ever published. More importantly, it is regarded as the keystone of the organic movement.Louis Bromfield called it "the best book I know on soil and the processes which take part in it." Soil Science called it "the most interesting and suggestive book on soil fertility which has appeared since King's Farmers of Forty Centuries." And Mother Earth News recently called it "the most basic of all introductions to organic farming by the founder of the modern movement."The object of the book was to draw attention to the loss of soil fertility, brought about by the vast increase in crop and animal production, that has led to such disastrous consequences as a general unbalancing of farming practices, an increase in plant and animal diseases and the loss of soil by erosion.
