摘　　要：Chickpea yield is decreasing day by day due to drought stress,which could be an immense risk for future food security in developing countries.Management practices could be the most excellent approach to diminish loss due to this abiotic factor.The current research work was designed to explore the tolerance reaction of chickpea genotypes against management practices,through morphological and biochemical parameters and evaluate yield performance across drought prone location of Bangladesh.Four genotypes BD-6048,BD-6045,BD-6090,BD-6092 and eight management practices,e.g.,severe water stress(SWS),i.e.,without irrigation,10 cm thick mulching with rice straw(MRS),10 cm thick mulching with water hyacinth(MWH),organic amendment through compost(OAC)@3 t ha−1,organic amendment through cow dung@5 t ha−1(OACD),organic amendment through poultry manure@2 t ha−1(OAPM),inorganic amendment through proline application(IAPA)as foliar spray and 16 h hydro-priming(HP).The study revealed that the genotypes BD-6048 showed excellent performance because of the highest chlorophyll,carotenoids,phosphorus,potassium,proline and protein content.The highest pod number plant−1 also increased seed yield in BD-6048.Considering management practices,IAPA increased relative water content,carotenoids,leaf phosphorus and potassium compared to other management practices and severe water stress.Finally,BD-6084 was selected as best genotype because of a significant increase in chlorophyll a and b,carotenoids,and relative water content with IAPA.Identified top performing genotypes can be used for releasing variety and cultivated for sustainable production in drought prone area of Bangladesh.
