This study presents a comprehensive analysis of soybean genotypes, focusing on the intricate relationships between plant growth parameters and their impact on productivity. The research utilized a diverse set of 40 soybean genotypes, cultivated in 5 replicates, to investigate the correlations between days to emergence, days to flowering, number of root nodules, maturity days, plant height, pod per plant, seed per pod and 1000 seed grain weight. The findings revealed significant positive correlations between days to emergence and maturity days and between plant height and number of root nodules. Additionally, the study showed a strong link between nodulation and both vegetative and reproductive parameters, suggesting that nodulation could be a key target for agricultural interventions aimed at improving crop yields. The data provided a valuable foundation for future research, which should aim to elucidate the causal mechanisms behind these correlations. The study's conclusions highlight the importance of understanding the genetic and environmental factors that contribute to plant growth and development, emphasizing the potential for selecting desirable characteristics in plant breeding.
