Abstract: A field experiment was conducted during kharif 2018 to study the influence of plant growth regulators on seed yield, quality and storability of soybean genotypes. Among the six genotypes, DSb-21 recorded significantly highest number of branches per plant (4.91) and number of pods per plant (78.34), whereas DSb-31 recorded highest pod length (3.36 cm), number of seeds per pod (3.42) and test weight (14.21 g). Foliar application of cycocel @ 250 ppm furnished significantly higher number of branches per plant (4.46), number of pods per plant (54.82), pod length (2.67 cm), number of seeds per pod (2.67) and test weight (13.15 g) as compared to control. Interaction between genotypes and plant growth regulators were found to be non-significant for morpho-physiological and yield attributes of soybean. The genotype Kalitur recorded highest initial seed quality parameters among the genotypes. Initial seed quality parameters viz., seed germination (93.82%) and seedling vigour index-II (112.60) were found to be significantly higher in salicylic acid @ 50 ppm spray. The interaction effect between genotypes and plant growth regulators were found to be non-significant for seed quality parameters except peroxidase activity and electrical conductivity. Similar trend was noticed up to nine months of storage for seed quality parameters.
