Abstract

A field experiment was conducted during summer season to study the effect of sowing dates and NPK combinations on growth and yield of sunflower. Sowing the crop on the 1st week of March proved to be better than delayed sowing on 4th week of March. Application of 80 Kg N+17.5 kg P+33.3 kg K ha−1 resulted in higher dry matter production (DM), leaf area index (LAI), number of seeds head−1, 1000-seed weight and seed yield compared with all other treatment combinations.
