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.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A major challenge for agronomists is developing cropping systems that exhibit superior performance across variable environmental conditions. Long-term field research trials provide a direct measure of the effect of environmental conditions within the context of treatment effects. Winter wheat (Triticum aestivum L.) is the most widely grown base crop in dryland systems of the semiarid central Great Plains, but grain yields are limited by nitrogen (N) and soil water availability. The goal of this research was to assess long-term cropping systems of winter wheat-grain sorghum-fallow in dryland. The focus was to determine the effect of three tillage practices and rates of N fertilization rates effects on the efficiency of the management system and grain yields for 2015-2018, and evaluate the yield stability for both crops in a 53-year-old crop rotation and fertility experiment. In the first study we evaluated the long-term effects of three different tillage practices and four N fertilizer rates on grain yield, protein content, and N use efficiency indices of winter wheat and grain sorghum in 2015-2018. The experiment was conducted on a long-term plot initiated in 1965 in Hays, KS as a split-split-plot arrangement of rotation, tillage, and N fertilizer treatments with four replications in a randomized complete block design. The main plots were the crop phase (winter wheat, grain sorghum, or fallow), sub-plots were three tillage treatments [conventional tillage (CT), reduced tillage (RT), and no-tillage (NT)]. The sub-sub-plots were four N rates (0, 22, 45, and 67 kg N ha−1) later modified in the 2015 growing season to 0, 45, 90, and 134 kg ha−1. Results showed tillage × N rate interaction had no significant (P = 0.608) effect on grain yield. Year × tillage and year × N rate had significant (P

Available in PDF, EPUB and Kindle. Book excerpt: While a good grasp of the many separate aspects of agriculture is important, it is equally essential for all those involved in agriculture to understand the functioning of the farming system as a whole and how it can be best managed. It is necessary to re-assess and understand rain-fed farming systems around the world and to find ways to improve the selection, design and operation of such systems for long term productivity, profitability and sustainability. The components of the system must operate together efficiently; yet many of the relationships and interactions are not clearly understood. Appreciation of these matters and how they are affected by external influences or inputs are important for decision making and for achieving desirable outcomes for the farm as a whole. This book analyses common rain-fed farming systems and defines the principles and practices important to their effective functioning and management.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to solve the problem of deteriorating soil health and the stagnation of yield in the rice-wheat-green gram cropping system (RWGCS) in Madwan Block, Muzaffarpur Bihar, from 2018 until 2023. The experiment included five crop scenarios based on conservation agriculture principles (CA), these interventions for improving soil health and enhancing crop yields, providing insights for future agricultural practices in the region. This study aimed to assess the impact of various tillage-based crop establishment and residue retention practices on soil health and agricultural system sustainability by developing a soil quality index (SQI). Soil properties were analyzed to create a SQI for 2018 and 2023 using Analytical Hierarchy Process (AHP) and Geographic Information System (GIS) to comprehensively assess soil quality. The treatment RPTR-BCW-BCG (T1), including random puddled transplanted rice, broadcasted wheat, and green gram with negligible residue integration, exhibited inferior soil quality ratings. Significant variations in soil parameters were identified among treatments during the research period. Moreover, treatment ZTDSR-HSZTW-HSG (T5), demonstrated high grain yields for rice (58.16 qt. ha-1 in 2020-21, 57.32 qt. ha-1 in 2021-22) and wheat (60.00 qt. ha-1 in 2020-21, 62.56 qt. ha-1 in 2021-22), as well as relatively high green gram yield (13.57 qt. ha-1 in 2020-21, 13.83 qt. ha-1 in 2021-22). Beneficial effects of positive outcomes in terms of crop output and sustainability as a result of implementing residue management and conservation tillage practices. The implementing CA methods, particularly the T5 treatment, can improve soil quality, enhance crop production sustainability, and promote overall agricultural system sustainability in the examined RWGCS. These results highlight the significance of managing agricultural residues and conservation tillage in maintaining soil health and ensuring long-term production in rice-wheat-green gram cropping systems.
