Influenced by Integrated Nutrient Management A. Mahapatra*, B. Gouda and D. Patel Odisha University of Agriculture and Technology, Bhubaneswar -751003, Odisha, India *Corresponding author ABSTRACT Introduction Sunflower is one of the most important high quality oilseed crop which is widely cultivated in different parts of the world. It ranks third in production next to soybean and groundnut. Sunflower oil is generally considered as a premium oil and fetches premium value in the market because of its light colour and high level of poly unsaturated fatty acids (PUFA), anti-cholesterol property with high level of linoleic acid and absence of linolenic acid, which helps in washing out cholesterol deposition in the coronary arteries of the heart and good for heart patient. But sunflower productivity is reduced due to rainfed or partially irrigated conditions, improper availability of hybrids and high yielding seeds suitable for different agro- climatic regions, improper nutrient management, bird attack, and major pests and diseases. Continuous use of high level of chemical fertilizers is adversely affecting the sustainability of agricultural production and causing environmental pollution. Therefore in the coming decades, integrated nutrient management will play a significant role in improving the crop yield as well as in International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 7 (2020) Journal homepage: http://www.ijcmas.com A field experiment was conducted at College of Agriculture, Odisha University of Agriculture and Technology, Bhubaneswar on sandy loam soils during summer season of 2018-19 with an objective of evaluating nutrient management for enhancing sunflower productivity (Helianthus annuus L.) under eastern Indian conditions. The experiment was laid out in a randomized block design with three replications. There were twelve treatment combinations viz., Control, RDF (60:80:60 kg N: P 2 O 5 : K 2 O/ha), RDF + S @ 40 kg/ha,RDF + B @ 0.02% ,RDF + S @ 40 kg/ha + B @ 0.02%,STBFR (60:100:60 kg N: P2O5: K2O/ha + S @ 40 kg/ha + B @ 0.02%) , FYM @ 5 t/ha ,RDF + FYM @ 5 t/ha, RDF + FYM @ 5 t/ha + S @ 40 kg/ha , RDF + FYM @ 5 t/ha + B @ 0.02% , RDF + FYM @ 5 t/ha + S @ 40 kg/ha + B @ 0.02%, STBFR + FYM @ 5 t/ha. The results of the study indicated that integrated nutrient management exhibited significant effect on growth, seed and oil yield of sunflower. Application of STBFR + FYM @ 5 t/ha recorded significantly highest growth parameters, seed(2.59 t/ha) and oil yield(1114 kg/ha) of sunflower which remained at par with RDF + FYM @ 5 t/ha + S @ 40 kg/ha + B @ 0.02%.
