Abstract:
In the present investigation an attempt has been made to study the effect of weather parameters on phenological stages and fruit yield components in tomato under late rabi planting condition. The experiment was conducted in a randomised block design with three replications. The results on mean sum of square revealed the existence of significant variation among the tested genotypes for all the characters studied except days to 50% flowering. Among the genotypes BT-106 recorded the highest number of fruits per plant (12.88) and fruit yield (134.75 q/ha). Plant height, number of branches per plant and number of flower clusters per plant showed positive correlation with maximum temperature (0.337; 0.598; 0.228) and minimum temperature (0.872; 0.892; 0.865) but negative correlation with relative humidity (-0.525; -0.979; -0.582). Fruit yield exhibited negative correlation with maximum temperature (- 0.331), minimum temperature (- 0.329) and evapotranspiration (-0.663) and positive correlation with relative humidity (0.304). This study revealed that fruit yield is influenced by mean temperature and evapotranspiration rather than maximum temperature and relative humidity under late rabi planting condition.
