Abstract
The present investigation was conducted at the Students’ Farm, College of Agriculture, Rajendranagar, Hyderabad, during kharif 2017-2018. Results of analysis of growth and physiological characteristics of soybean genotypes showed that highest and lowest plant heights were recorded in Basara and ASB-16, respectively. More number of days to 50% flowering, was recorded for the genotype JS-335 and less in JS-93-05, MACS- 1460 and ASB-15 whereas days to reach maturity was highest in the genotypes JS-335, Basara, NRC-37, ASB-15 and lowest for the genotype JS-93-05. The maximum LAR was recorded for the genotype MACS-1460 while the maximum NAR was in the genotype ASB-15 and minimum was for MACS-1460 at 30- 45 DAS. The highest SLA was recorded in genotype JS-93-05 and the minimum was recorded in ASB-15, whereas the highest SLW was recorded in ASB-15 and the lowest was recorded in the genotype JS-93-05. Hence genotypes MACS-1460, NRC-37 and Basara were morphologically, physiologically more efficient among the soybean genotypes during kharif season.
