Standardization of best management practices for yield maximization in sunflower (Helianthus annuus L.)

Abstract

A field experiment was conducted to standardize the best management practices for higher yields in sunflower at ZARS, UAS, GKVK, Bengaluru during kharif 2011. The results revealed that application of FYM @ 5 t/ha along with 133 percent RDF (120: 120: 80 kg N: P2O5: K 2O/ha) at higher plant population level (P3-74074 plants/ha) recorded higher seed yield (2478 kg/ha) which was statistically at par with 100% RDF with same level of FYM and plant population (2464 kg/ha). Higher oil yield was observed with 100% RDF with FYM @ 5 t/ha & higher plant population (1014 kg/ha) followed by 133% RDF (1011 kg/ha). Hence, adoption of higher plant population level of 74074 plants/ha along with 100 percent RDF and FYM (5 t/ha) is sufficient to generate remunerative income (Rs. 51450/ha) and higher B:C ratio (3.29).
