Weather relationship and evaluation of CROPGRO-soybean

Agrometeorological indices interaction of soybean productivity will be influence different weather parameter Soybean (Glycine max. [L] Mirrll.) is one of the leguminous pulse grain and oil seed crops in tropical and sub-tropical regions. Study revealed that the weather had played a significant role in deciding the yield of soybean. However, the weather variables had affected the crop growth, development and yield differently in different phenophases during its growing period. Accumulated GDD utilized by different dates of sown crop to attain the maturity was almost different to respective dates of sowing treatments. Further, it was noticed that conversion efficiency of incident PAR (IPAR) to dry matter production varied much with date of sowing and with four levels of spacing. However, the heat use efficiency varied with the date of sowing of soybean crop. Correlations were contemplated to have an insight on effect of different weather parameters to identify the critical phenophases of soybean crop most sensitive to particular weather parameter.
