Abstract:
Field experiment was conducted to determine N, P and K requirements of sunflower (Helianthus annuus L.) grown under Bahawalpur irrigated conditions on medium heavy loam soil. Four levels of N (0,60,120,180 kg NPK ha-1) four levels of P2O5 (0,30,60,90 kg NPK ha-1) and four levels of K2O ( 0,60,120,180 kg NPK ha-1) in combinations were put to test. Data collected on seed yield and yield components were subjected to standard statistical analysis. The crop indicated positive/significant response to N, P and K application. Significant positive correlation was observed between seed yield and head size. Optimum fertilizer requirement computed was 120-90-60 kg NPK ha-1 for sunflower crop under experimental condition.
