Effect of growth regulators, seaweed extract and potassium nitrate on growth, yield and quality of soybean (Glycine max (L.) Merrill)

Abstract

The field investigation entitled “Effect of growth regulators, seaweed extract and potassium nitrate on growth and yield of soybean (Glycine max (L.) Merrill)” was conducted at experimental farm, Department of Agronomy, College of Agriculture, VNMKV, Parbhani during kharif 2018-19. The experiment was laid out in a randomized block design with seven treatments and three replications with a view to find out the influence of different growth regulators, seaweed extract and potassium nitrate applied at flowering and pod developing stage of soybean. From the result it was revealed that application of seaweed extract-20% at flowering and developing stage recorded higher plant height, more number of functional leaves, higher leaf area, higher number of branches, higher dry matter accumulation, higher seed yield, higher oil content and oil yield, higher protein content and protein yield, and it was at par with GA3-100ppm and Salicylic acid-50ppm.
