EFFECT OF DIFFERENT NUTRIENT MANAGEMENT ON GROWTH AND YIELD OF KHARIF SUNFLOWER (HELIANTHUS ANNUUS L.)

A field experiment was carried out during kharif, 2023 at Experimental Farm of Agronomy Section, College of Agriculture, Latur to study the nutrient management in kharif sunflower (Helianthus annuus L.).The experiment was laid out in Randomized Block Design (RBD) with seven treatments replicated thrice.The treatments were T 1 -RDF (80:40:40 kg NPK ha -1 ), T 2 -RDF + FYM 5 t ha -1 , T 3 -RDF + Multimicronutrient Grade-I @ 25 kg ha -1 , T 4 -RDF + FYM 5 t ha -1 + Multimicronutrient Grade-I @ 25 kg ha -1 , T 5 -RDF + Spraying of Multimicronutrient Grade-II @ 0.2% at 25 DAS and 45 DAS, T 6 -RDF + FYM 5 t ha -1 + Spraying of Multimicronutrient Grade-II @ 0.2% at 25 DAS and 45 DAS and T 7 -Control.The results showed that the growth and yield attributes of sunflower were influenced significantly due to the different treatments.Application of RDF + FYM 5 t ha -1 + Multimicronutrient Grade-I @ 25 kg ha -1 (T 4 ) recorded significantly highest plant height (198.85 cm), number of functional leaves plant -1 (35.04), leaf area plant -1 (74.85 dm 2 ), stem girth (7.93 cm), dry matter accumulation plant -1 (208.25 g), seed yield (1942 kg ha -1 ), biological yield (7187 kg ha -1 ) and oil yield (636 kg ha -1 ) being at par with application of RDF + Multimicronutrient Grade-I @ 25 kg ha -1 (T 3 ) and RDF + Spraying of Multimicronutrient Grade-II @ 0.2% at 25 DAS and 45 DAS (T 6 ) over rest of the treatments.
