This book was released on 2009-05-07 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is the main occupation in India and about 75% of its population depends directly or indirectly on agriculture for their livelihood. It is the dominant sector that contributes 18% of the gross domestic product. Thus, agriculture is the foundation of the Indian economy. The maximum share of Indian exports is also from the agriculture sector. As the population of the country is increasing trem- dously, approximately at the rate of 19 million every year over the existing popu- tion of more than 1 billion (approximately 1. 18 billion), the food grain production must necessarily be increased. This can be done by increasing crop production to match the population growth rate of 2. 2% per annum, which is expected to stabilize at 1. 53 billion around 2050. There is no doubt that the Green Revolution in India during the late 1960s brought self-sufficiency in food grain production, mainly through the increase in rice and wheat crop yields – the two main crops of the country which play an important role from food security point of view. However, the excessive use of fertilizers and pesticides, and the neglect of organic manures for these crops, has resulted in the deterioration of physical, chemical and biological health of the ri- and wheat-growing soils. Owing to the deterioration of the health of these soils, the productivity of the rice–wheat cropping system has now either got reduced or in some places has become constant for the last decade.
Download or read book Organic Farming of Rice based Cropping Systems written by Mohammadreza Davari and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rice (Oryza sativa L.) - wheat (Triticum aestivum L.) cropping system occupies about 28.8 million hectares mainly spread over Asia's five countries, namely, India, Pakistan, Nepal, Bangladesh and China. Organic farming offers alternative system for sustainable production and natural resource system. The aim of nutrient management in organic systems is to optimize the use of on-farm resources and minimize losses. Organic materials such as farmyard manure, compost, vermicompost, biogas slurry, green manures, crop residues, biofertilizers and cover crops are other valuable source of nutrients to improve the growth and yield attributes, yields, nutrient uptake, grain quality and soil fertility. The present book is a part of studies which is conducted to determine the optimum combination organic manures crop residues and biofertilizers for meeting nutritional requierment of rice-wheat and rice-wheat-mungbean cropping systems. It also focuses on studying the impact of organic farming practices on the health of soil, quality of organically grown products in order to find out economics of organic farming of rice-based cropping systems.

Download or read book Fertilizer Application on Crop Yield written by Jagadish Timsina and published by MDPI. This book was released on 2019-04-02 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fertilizer application can increase crop yields and improve global food security, and thus has the potential to eliminate hunger and poverty. However, excessive amounts of fertilizer application can contribute to groundwater pollution, greenhouse gas emissions, eutrophication, deposition and disruptions to natural ecosystems, and soil acidification over time. Small farmers in many countries think inorganic fertilizers are expensive and degrade soils, and thus policymakers want to promote organic instead of inorganic fertilizers. To develop practical fertilizer recommendations for farmers, yield responses to applied fertilizers from inorganic and organic sources, indigenous nutrient supply from soil, and nutrient use efficiency require consideration. There is a lack of sufficient scientific understanding regarding the need and benefit of integrated nutrient management (i.e., judicious use of inorganic and organic sources of nutrients) to meet the nutrient demand of high-yielding crops, increase yields and profits, and reduce soil and environmental degradation. Inadequate knowledge has constrained efforts to develop precision nutrient management recommendations that aim to rationalize input costs, increase yields and profits, and reduce environmental externalities. This Special Issue of the journal provided some evidence of the usefulness of integrated nutrient management to sustain soil resources and supply nutrients to crops grown with major cereal and legume crops in some developing countries.

The aspects related to system based nutrient budgeting, soil carbon management and sequestration, balanced crop nutrition in relation to crop diseases, economics and nutrient modeling have been duly discussed in s from 19 to 25.
Download or read book Crop Residue Management in Rice Wheat Cropping System written by M. L. Dotaniya and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book "Crop Residue Management in Rice-Wheat Cropping System" has written for plant nutrient management in rice - wheat cropping system with nitrogen and potassium fertilizers. The rice-wheat cropping system is one of most widely practiced cropping system in India as well as across the world. The nutrient management in this system is a big task; both crops are heavy nutrient feeder. It requires nutrient cycling from organic residues to maintain nutrient balance in soil. Addition of organic matter to the soil through the return of crop residues also improves soil structure, influences soil water, air and temperature relation, helps to control runoff and erosion and makes tillage easier. Therefore, use of renewable organic sources would be essential for sustainability of the rice-wheat system. This book provides the information about NPK nutrient balance and crop performance under crop residue management practices.
