Abstract
Drought and heat stress are two major abiotic stresses that challenge the sustainability of agriculture to a larger extend. The changing and unpredictable climate further aggravates the efforts made by researchers as well as farmers. The stresses during the terminal stage of cool-season food legumes may affect numerous physiological and biochemical reactions that may result in poor yield. The plants possess a good number of adaptative and avoiding mechanisms to sustain the adverse situation. The various agronomic and breeding approaches may help in stress-induced alteration. The physiological and biochemical response of crops to any adverse situation is very important to understand to develop mechanisms and approaches for tolerance in plants. Agronomic approaches like altering the planting time, seed priming, foliar application of various macro and micro nutrients, and the application of rhizobacteria may help in mitigating the adverse effect of heat and drought stress to some extent. Breeding approaches like trait-based selection, inheritance studies of marker-based selection, genetic approaches using the transcriptome and metabolome may further pave the way to select and develop crops with better heat and drought stress adaptation and mitigation.
Highlights
This review presents a zest of the effect of heat and drought stress, its effect on plants, and mitigation strategies
Relay sowing of cool-season legume crops after rice reduces the negative impact of terminal drought and heat stress during the reproductive phase of the pulse crop by overlapping part of its early growth stage with the previous crop
It has been reported by Gangwar et al [126] and Kar and Kumar [127] that legumes grown after wet season rice with reduced or minimum tillage give a higher yield
Summary
Food legumes or cool-season legumes are protein-rich and are commonly called ‘poor man’s meat’ They help to meet the diverse demand for food, fiber, and fodder in several agricultural systems [1,2]. Pulses like broad beans (Vicia faba), lupin (Lupinus spp.), lentils (Lens culinaris), chickpeas (Cicer arietinum), grass peas (Lathyrus sativus), dry peas (Pisum sativum), and the common vetch (Vicia sativa) are included in the list of cool-season pulses [3]. They are named so mainly because of the cooler conditions they require for vegetative growth. Though cool-season food legumes are of less importance in world production and consumption, they form a very imperative component in the Indian diet
