Impact of integrated crop management practice in sunflower variety RSFH-1887 under farmers’ field

Abstract

A frontline demonstration was conducted to study the impact of sunflower variety RSFH-1887 for two years, during 2021-22 and 2022-23 by ICAR-Krishi Vigyan Kendra, Bagalkote (Karnataka) with an objective to assess the yield level with an improved package of practice over with farmers’ practice and its economic impact. By adopting improved package of practice along with sunflower variety RSFH-1887, pooled data of two years recorded higher plant height (168.5 cm) and 100 seed weight (5.04 g) as compared to farmers’ practice (156.9 cm and 4.67 g, respectively). The percent disease incidence (PDI) of alternaria leaf blight in improved practice was 8.34 per cent and in farmers practice was 11.38 per cent and the PDI of sclerotium stem rot in improved practice was 4.46 per cent and in farmers practice it was noticed 10.87 per cent. The per cent disease reduction of alternaria leaf blight and sclerotium stem rot was to the tune of 26.71 per cent and 58.97 per cent, respectively. Pooled data on grain yield was recorded in improved practice (9.93 q ha-1) as compared to farmers’ practice (8.68 q ha-1). The increase in the grain yield of the sunflower variety RSFH-1887 with improved practice was to the tune of 18.14 per cent over the farmers’ practice. Average of two year extension gap (1.61 q ha-1), technology gap (14.55 q ha-1) and technology index (58.18%) was observed in the study. Higher gross return (Rs. 533115 ha-1), net return (Rs. 32143 ha-1), and B:C ratio (2.54) was noticed in improved practice as compared to farmers practice (Rs. 44926 ha-1, Rs. 17668 ha-1 and 1.65, respectively). The adoption of a sunflower variety RSFH-1887 with improved practice realized an additional income of Rs. 14475 per hectare. This kind of improved variety with improved practices motivates the other farmers to adopt for getting higher income.
