Influences of different varieties planted under various seed rates on physiological traits of wheat

The influences of different wheat varieties (Sarsabz, Kiran-95, TD-1) and seed rates (100, 125 and 150 kg ha-1) on physiological traits were investigated at Sindh Agriculture University, Tandojam Pakistan. It was observed that the leaf area, net assimilation rate and crop growth rate were significantly higher in Kiran-95 than that of Sarsabz and TD-1. While chlorophyll a, b and chlorophyll total appeared better in TD-1 than that of Kiran-95 and Sarsabz. The results despite the maximum leaf area and chlorophyll a appeared high at seed rate of 125 kg ha-1 than that of 100 and 150 kg ha-1, however, the differences among them were statistically non significant (P> 0.05). The maximum leaf area, net assimilation rate and crop growth rate at seed rate of 125 kg ha-1 were in Kiran-95, and the maximum chlorophyll a under seed rate of 125 kg ha-1, chlorophyll b, and total under seed rate of 100 kg ha-1 werein TD-1 variety. Based on the findings it is concluded that Kiran-95 under seed rate of 125 kg ha-1, performed better followed by TD-1 and Sarsabz.
