The effect of different seed rates on agro- physiological traits of wheat varieties was investigated at agronomic research area, Faculty of Agriculture, Gomal University D.I. Khan. Six wheat varieties viz. Inqilab-91, Bakhtawar-92, Punjab-96, Dera-98, Daman-98 and Raj. were tested using varying seed rates of 50, 100, 150 and 200 kg seed per ha under a split plot arrangement during 2000-01. The effect of seed rates was significant on most of agro-physiological traits of tested varieties. Tillers m-2, fresh weight, crop growth rate, net assimilation rate, photosynthetic efficiency and protein content were high at higher seed rate of 200 kg per ha. Among wheat varieties, Inqilab-91 produced maximum fresh weight, net assimilation rate, photosynthetic efficiency and grain yield. Daman-98 produced more dry weight (9.15 t per ha) and protein content (11.40%). Tillers m-2 (350.4) and maximum crop growth (15.04 g d m-2) rate was recorded for punjab-96. In interaction, maximum grain
