ABSTRACT
The experiment was conducted to study the effect of various phosphorous levels on the yield and yield components of sunflower variety Hysun-33 at the Agronomic Research Area, Faculty of Agriculture, Gomal University, Dera Ismail Khan during the year 2010. The phosphorous levels studied were 0 (N :P2O5: K2O), 0 (P2O5), 10, 20, 30, 40, 50, 60 P2O5 Kg/ha. The results showed significant effect of P2O5 @ 50 kg/ha and 60 kg/ha as compare to lower doses of phosphorous. All varying levels of phosphorous affected the head diameter, number of seeds per head, 1000-seeds weight, achenes yield and achenes oil content but significant positive effect was observed where P2O5 @ 60 kg/ha N @ 50 kg/ha and K2O 15 kg/ha was applied. However, number of plants, remained non-significant. It is, therefore, recommended to apply phosphorous @ 60 kg/ha for obtaining higher yield of sunflower.
