Pod and seed number are the most important yield components of soybean. Leaf area index (LAI), leaf area duration (LAD) during the reproductive period strongly influence yield components. The study was undertaken with objectives to investigate the significant differences in yield components, physiological traits and growth parameters among genotypes and to examine the dynamics of LAI and LAD during the reproductive period for the high-yielding genotypes. Significant variations were found for LAI, LAD, leaf area, number of branches, plant height and physiological traits. Photosynthetic rate was closely related to stomatal conductance, transpiration and PAR.The rate of photosynthesis is an important physiological parameter which governs the dry matter production and consequently the yield.The genotype KDS-347 (63.60 μmol m-2s-1) showed higher photosynthesis rate reflected in high grain yield (2708.33 kg/ha) in these genotypes during summer season. The efficiency of converting biological yield in to economic yield and explained the cause of high grain yield in KDS-347 due to a higher harvest index (46.78%). The high yielding genotypes possessed higher rate of photosynthesis indicating the importance of the parameter in determining the productivity.

Photosynthetic rate was closely related to stomatal conductance, transpiration and PAR.The rate of photosynthesis is an important physiological parameter which governs the dry matter production and consequently the yield.The genotype KDS-347 (63.60 μmol m-2s-1) showed higher photosynthesis rate reflected in high grain yield (2708.33 kg/ha) in these genotypes during summer season. The efficiency of converting biological yield in to economic yield and explained the cause of high grain yield in KDS-347 due to a higher harvest index (46.78%).
