Sunflower is a one of the most important oilseed crop. Production of sunflower with the use of sustainable source of nutrient is cheap as compared to the application of synthetic fertilizers and its quality and soil heath improved by the application of organic-chemical source of nutrient, while chemical fertilizers are generally dangers for our environment and soil health. The nutrient requirement of sunflower can easily be carried by the self made organic-chemical source of nutrient through this equation FYM+CaCO3+ H2O+ NO3 = OC (Organic chemical source of nutrient) with very low cost, so a farmer can self made and fulfill nutrient requirement of crop and can obtain higher yield. A field experiment was carried out during 2013 at village Mir khan Leghari near Agriculture Training Institute Sakrand, District Nawabshah (Sindh). The sunflower variety HO-1 was sown by using RCBD with tree replications. Three levels of self made OC source of nutrient viz: T1 = 200 kg ha-1, T2 = 300 kg ha-1 and T3 = 500 kg ha-1 was used. Regarding to the result maximum plant height, stem girth, number of leaves , head diameter, seed yield (14 cm, 7.60 cm, 16 plant-1 , 15.70 cm, 1580.00 kg ha-1 respectively) were recorded in T3 in which high dose (500 kg ha-1) of self made organic-chemical (OC) source of nutrient were applied. While the minimum plant height 10 cm, stem girth 3.25 cm, leaves plant-1 12, head diameter 9.50 cm, seed yield 1300.40 kg ha-1 were recorded in T1 plot, where low dose (200 kg ha-1) of self made organic-chemical (OC) source of nutrient were applied in this plot.
