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.
