Book Description
Master's Thesis from the year 2018 in the subject Agrarian Studies, grade: 8.5, course: Agronomy, language: English, abstract: The aim of this study is to study the effect of integrated nutrient management on the growth and yield of kharif Maize and to work out the economics of different nutrient management treatments. As the chemical's fertilizers play an important role in plants life so that these chemicals should not be avoided completely as they are the potential sources of the high amount of nutrients in easily available forms. These fertilizers greatly affect enzymatic activities in the soil profile but poor management of the chemical fertilizers has a key role in lowering the yield productivity and deteriorate the soil health also. So, to achieve optimum crop production, there is a need to use the combination of organic sources, inorganic sources, bio-fertilizers. Maize (Zea mays L.) requires the nutrients i.e., macronutrients as well as micronutrients for obtaining the higher crop growth and yield. The micronutrients content in organic manure may be sufficient to meet the crop requirement but the low soil fertility is the major problem to maintain sustainability in production. The application of organic manure do not produce optimum yield due to low nutrient status but they play a direct role in plant growth by the mineralization they provide the essential nutrients which furthermore improves the physical and biological properties of the soil. The use of organic plays an important role in maintaining soil health due to the build-up of soil organic matter, beneficial microbes. "Biofertilizer" is a substance that contains living organisms. It promotes growth by increasing the supply or availability of primary nutrients to the host plant. These are not fertilizers because fertilizers directly increase soil fertility by adding nutrients. They add nutrients through the natural processes of fixing atmospheric nitrogen, solubilizing phosphorus, and stimulating

Book Description
This book addresses in detail multifaceted approaches to boosting nutrient use efficiency (NUE) that are modified by plant interactions with environmental variables and combine physiological, microbial, biotechnological and agronomic aspects. Conveying an in-depth understanding of the topic will spark the development of new cultivars and strains to induce NUE, coupled with best management practices that will immensely benefit agricultural systems, safeguarding their soil, water, and air quality. Written by recognized experts in the field, the book is intended to provide students, scientists and policymakers with essential insights into holistic approaches to NUE, as well as an overview of some successful case studies. In the present understanding of agriculture, NUE represents a question of process optimization in response to the increasing fragility of our natural resources base and threats to food grain security across the globe. Further improving nutrient use efficiency is a prerequisite to reducing production costs, expanding crop acreage into non-competitive marginal lands with low nutrient resources, and preventing environmental contamination. The nutrients most commonly limiting plant growth are N, P, K, S and micronutrients like Fe, Zn, B and Mo. NUE depends on the ability to efficiently take up the nutrient from the soil, but also on transport, storage, mobilization, usage within the plant and the environment. A number of approaches can help us to understand NUE as a whole. One involves adopting best crop management practices that take into account root-induced rhizosphere processes, which play a pivotal role in controlling nutrient dynamics in the soil-plant-atmosphere continuum. New technologies, from basic tools like leaf color charts to sophisticated sensor-based systems and laser land leveling, can reduce the dependency on laboratory assistance and manual labor. Another approach concerns the development of crop plants through genetic manipulations that allow them to take up and assimilate nutrients more efficiently, as well as identifying processes of plant responses to nutrient deficiency stress and exploring natural genetic variation. Though only recently introduced, the ability of microbial inoculants to induce NUE is gaining in importance, as the loss, immobilization, release and availability of nutrients are mediated by soil microbial processes.

Sustainable Cropping Systems
Author: Jeffrey A. CoulterPublisher: MDPI
ISBN: 3039289071
Category : Science
Languages : en
Pages : 326
Book Description
Global crop production must substantially increase to meet the needs of a rapidly growing population. This is constrained by the availability of nutrients, water, and land. There is also an urgent need to reduce the negative environmental impacts of crop production. Collectively, these issues represent one of the greatest challenges of the twenty-first century. Sustainable cropping systems based on ecological principles are the core of integrated approaches to solve this critical challenge. This special issue provides an international basis for revealing the underlying mechanisms of sustainable cropping systems to drive agronomic innovations. It includes review and original research articles that report novel scientific findings on improvement in cropping systems related to crop yields and their resistance to biotic and abiotic stressors, resource use efficiency, environmental impact, sustainability, and ecosystem services.

Book Description
The burgeoning demand on the world food supply, coupled with concern over the use of chemical fertilizers, has led to an accelerated interest in the practice of precision agriculture. This practice involves the careful control and monitoring of plant nutrition to maximize the rate of growth and yield of crops, as well as their nutritional value.
