Abstract
Background: Sunflower is an important oilseed crop. At present, the production of sunflower crop is less due to poor nutrient management practices. Excessive use of chemical fertilizers not only increases the cost of production but also leads to deterioration of soil and human health. The integrated use of nutrients from fertilizer and organic manure sources seems to be the need of the hour. Thus, integrated nutrient management holds great promise in meeting the growing nutrient demand of modern agriculture. Methods: A pot experiment was conducted during pre-kharif season (March-June) of 2022 to study the effect of integrated nutrient management on growth, yield and quality of Sunflower. The experiment was laid out in Completely Randomized Design with three replications and consisted of seven treatments viz., T1, T2, T3, T4, T5, T6 and T7. Result: T7 (FYM 10 t ha-1 + 100% RDN) recorded highest in yield attributing characters i.e., head diameter (14.50 cm), number of seeds head-1 (783.33), seed yield (26.67 g pot-1) and stover yield (48.33 g pot-1). Maximum NPK uptake for both seed and stover was recorded highest in FYM @ 10 t ha-1 + 100% RDN. Maximum available soil N was recorded in T7(FYM @ 10 t ha-1 + 100% RDN) with 328.96 kg ha-1 while maximum available soil P and K was recorded in T2 {100% RDF (60:40:60) kg ha-1} with 29.25 kg ha-1 and 230.79 kg ha-1, respectively.
