Rice farmers are mostly involved in monoculture practices. This deprives the land for growing other food crops. Hence, a better alternative of mono/sole cropping is required to overcome this shortcoming. Therefore, a shift from mono cropping to inter/multiple cropping as an excellent strategy for intensifying land use and increasing income and production per unit area and time is appreciated. Production efficiency, economic efficiency and employment generation efficiency of any diversified system is a direct measure of its preferability. Keeping this view in mind, this study deals with the production potential and economic viability of different rabi intercropping in rabi cereal, legume, oilseeds and spices to identify the suitable/remunerative rice (Oryza sativa L.) based cropping systems.
Abiotic Stresses in Field Crops: Response, Impacts and Management under Climate Change Scenario
Agriculture is globally challenged by adverse environmental factors, including drought, heat, waterlogging, cold, soil salinity and sodicity, nutrient deficiency, heavy metal contamination, and other edaphic stresses. These stresses impair plant functioning at multiple levels limiting plant development and crop productivity. In the current climate change scenario, the increase in frequency and intensity of these stresses is posing a serious threat to overall food and nutrition security. Plants respond to these stresses through several tolerance mechanisms operating at molecular, biochemical, physiological, or morpho-anatomical levels depending on their developmental stage and type of species. The cope-up strategy also differs depending on abiotic stress type, duration, and intensity. The extent, to which these changes occur to counteract the impact of abiotic stresses as well as the pathways involved in plant acclimation, is not fully understood. An advance in understanding agricultural crops' adaptation and tolerance mechanisms underlying trans-generational effects, epigenetic changes, and stress memory will significantly help in comprehending the implications as well as devising mitigation strategies for sustainable agriculture and, thus, food security. Additionally, it is crucial to understand the interactions and impacts of combined stresses to efficiently advance the development of combined stress-tolerant crops as well as devising mitigation strategies for various climatic stressors.
Farming System and Sustainable Agriculture
The land holding of the farmer is decreasing day by day due to urbanisation and there is no chance for horizontal increase in agricultural land. To increase the income of the farmers, few steps for vertical increase in agricultural production have been discussed in this book. A detailed and comprehensive information regarding the historical background of farming system, farming system and its components, integrated farming system and allied enterprises, integrated farming system models in different agroclimatic zones, role of integrated farming system in agriculture and livelihood security, resource cycling and flow of energy in different farming systems, role of crop residues in agriculture, farming system of dryland agriculture, role of agroforestry in farming system, scope of organic farming in farming system have been given. A detailed information regarding the latest concepts of agronomy like conservation agriculture strategies in cropping system, sustainable agriculture, scope of hydroponics techniques in agriculture have also been discussed. In the end tools for determining production and efficiencies in cropping and farming system have also been given.
