چکیده

The clamor for agricultural resources is being pushed up by global climatic change and population growth. Such consequences are huge challenges to food security, wreaking havoc on the agroecosystem and causing biotic and abiotic stresses in plants, which in turn cause metabolic and physiological problems. Food legume crops contribute to food security in underdeveloped countries by playing an essential role in conservation farming methods. Drought has, nevertheless, exhibited a negative impact on productivity in many parts of the world. While water shortage is a significant abiotic barrier to legume crop output, drought impacts differ depending on drought timing, agro-climatic area, soil texture, and legume species. To resolve these concerns, we gathered data from the recent publications that revealed drought-induced changes in the production of monoculture legumes in field circumstances and examined it using meta-analysis approaches. Research findings revealed that the water cut’s quantity was strongly associated with a decrease in yield. However, the magnitude of the effect differed depending on the phenological stage of the drought and legume species. The legumes such as groundnut and lentil exhibited the lowest yield reductions (31.2% and 19.6% for groundnut and lentil, accordingly), however, the biggest yield drop (39.8%) facing the maximum water reduction was for faba bean.
