The experiment was consisting of 90 genotypes to study the difference in growth, morpho-physiological characterization and yield response of soybean. The genotype JS 21-72 followed by JS 22-18 and PS-1613 recorded the highest number of leaves per plant. AGS-48 showed maximum plant height among all other genotypes. Genotype DS 31-09 followed by JS 22-16 produced the maximum number of pods per plant. DS 31-09 followed by JS 22-16 produced maximum number of pods per plant with respects to all another genotype Early work with infrared thermometers proved successful in monitoring plant Evaporative rate. The canopy temperature in the current study ranged from 32.13 Original Research Article
