Using Biochemical and Growth Parameters to Assess Soybean Yield Potential

Using Biochemical and Growth Parameters to Assess Soybean Yield Potential Sachin Ashvathama V.H. G. K. Naidu Kiran B.O.

This study, conducted in 2022 at the All India Coordinated Research Project on Soybean Dharwad, aimed to evaluate the yield potential of ten soybean genotypes, including three checks, using biochemical and growth parameters. Employing a randomized block design, the study assessed variations in chlorophyll content, which was highest in genotypes DLSb 3, DSb 34, and DSb 23. Significant differences among genotypes were observed in absolute growth rate (AGR), crop growth rate (CGR), relative growth rate (RGR), and net assimilation rate (NAR). Notably, DSb 34 and DLSb 5 exhibited the highest AGR and CGR at 60-90 days after sowing (DAS), while RGR was most pronounced in DSb 39 at 30-60 DAS. NAR peaked at 60-90 DAS, with DLSb 1 showing the highest values. Yield component analysis identified DLSb 5 and DSb 34 as the top-yielding genotypes, with significant variations in the number of pods per plant among the genotypes. These findings highlight key traits for breeding higher-yielding soybean varieties and offer valuable insights for future research and practical applications in crop improvement.”
