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...
Mechanisms of Stress Tolerance in Horticultural Crops: Physiological and Molecular Insights
The field of horticultural crop production is increasingly challenged by both abiotic and biotic stressors, exacerbated by global climatic changes and anthropogenic activities. These stressors, including salinity, drought, temperature extremes, and heavy metal contamination, significantly impact plant growth, yield, and quality. Horticultural crops exhibit varied responses to these stressors, particularly during critical growth phases such as seedling establishment, vegetative growth, reproductive stages, and senescence. Recent studies have highlighted the importance of understanding the physiological, biochemical, and molecular responses of these crops to stress. However, gaps remain in fully elucidating the resistance mechanisms and mitigation strategies. Additionally, biotic stressors like viruses, fungi, bacteria, insects, and nematodes further compromise crop vigor and productivity. The role of biostimulants, hormones, novel chemicals, and microorganisms in enhancing stress tolerance is an emerging area of interest, with recent findings pointing to the beneficial effects of phytochemicals, secondary metabolites, and antimicrobial peptides in stress mitigation.
Conservation Agriculture in Subsistence Farming
Conservation agriculture systems have long-term impacts on livelihoods, agricultural production, gender equity, and regional economic development of tribal societies in South Asia. This book presents South Asia as a case study, due to the high soil erosion caused by monsoon rainfall and geophysical conditions in the region, which necessitate conservation agriculture approaches, and the high percentage of people in South Asia relying on subsistence and traditional farming. The book takes an interdisciplinary approach to analyse systems at scales ranging from household to regional and national levels.
Multiple Abiotic Stress Tolerances in Higher Plants
In the last 50 years, classical breeding has played a significant role in achieving higher crop productivity, but major crops have reached a plateau in their yield potential. Therefore, the current focus for sustainable intensification of agriculture is the use of biotechnological approaches to enhance the yield potential by combating the yield losses that occur due to abiotic stresses. The abiotic stresses are governed by multigenes, and therefore, a holistic approach is needed to get success in imparting stress tolerance to enhance the yield potential of our crops. Plants face multiple stress conditions during their life stages and adopt several physiological, biochemical, and molecular st...
Climate-Smart Sugarcane Cultivation
Sugarcane is a crucial eco-friendly cash crop with massive agro-industrial value as a sweetener and a source of renewable energy. Known for its high varietal resistance to changing climate scenarios, sugarcane is also reported to be prone to biotic stresses like drought, water logging, salinity, multiple soil-related problems, and nutrient deficiencies. This new volume is a 700-plus-page comprehensive resource offering state-of-the-art practical information on sugarcane cultivation and management based on the practical experience, knowledge, and research from around the world. Key features: Discusses the impact of global warming and climate change on sugarcane production and offers mitigation and adaptation strategies Presents a plethora of new climate-smart technologies for sugarcane cultivation and management Considers climate-smart sugarcane fertilization strategies as well as climate-smart pest management Looks at recycling and alternate uses of sugarcane products and byproducts for bioethanol production and other purposes
Potential Pulses
The fight against global hunger demands a fresh perspective. Lesser-known legumes, often called 'potential pulses', can play a pivotal role. These underutilized powerhouses, including adzuki bean, bambara groundnut, faba bean, cowpea, grass pea and horse gram, among others, are currently untapped resources. Their potential goes beyond their ability to thrive in harsh environments (caused by high temperature, drought, etc.) and fix nitrogen. With increased understanding of these legumes and their genetic and genomic potential, we can unlock a new world of sustainable and nutritious food sources. Focusing on the untapped genetic and genomic potential of these legumes, this book empowers researchers, breeders, and policymakers to unlock a new era of food and nutritional security. By leveraging the power of their genes, we can transform underutilized pulses into the nutritional heroes of tomorrow.
