Abstract:
An experiment was conducted to study the effect of fertilizers levels and cultivars on Sugarcane yield and economics crop at Agriculture Research Station, Kumta, Uttara Kannada of University of Agricultural Sciences, Dharwad during 2018-19 and 2019. The experiment consisted three main plots (Cultivars) viz., C1-SNK635, C2- Co-86032 and C3 – Konanakatte and five sub plots (Fertilizers levels) F1: 75% RDF, F2: 100% RDF, F3:125% RDF, F4: 150% RDF and F5: control. The experiment was laid out in Strip Block Design with three replication. The results indicated that the cane yield of plant cane was influenced significantly by RDF levels, and cultivars and their interactions. Among cultivars, SNK-635 recorded significantly higher cane yield (133.9 t ha-1) than Co-86032 (114.3 t ha-1) and Konanakatte (81.8 t ha-1). Cultivar Co-86032 also had significantly higher cane yield than Konanakatte. Different RDF levels treatments (F1 to F4) recorded significantly higher cane yield than control treatment. There was increased cane yield with increased levels of fertilizers. Application of 150% RDF recorded significantly higher cane yield (137.6 t ha-1) than control (71.0 t ha-1) and 75% RDF (96.1 t ha-1) but on par with 125% (128.5 t ha-1) and 100% RDF (116.8 t ha-1). Sugarcane cultivar SNK- 635 recorded significantly higher net return (₹274933 ha-1) compared to Co-86032 (₹219103 ha-1) and Konanakatte (₹126559 ha-1). The cultivar Konanakatte gave lower net returns (₹126559 ha-1). Among nutrient management treatments, 150% RDF given significantly more net returns (₹268947 ha-1) than control (₹144968 ha-1), 75% RDF ( (₹160262 ha-1) and 100% RDF (₹214279 ha-1) but on par with 125% RDF (₹245868 ha-1). Significantly lower net returns was recorded in control treatment (₹144968 ha-1). Among RDF levels, lower net returns recorded in 75% RDF (₹160262 ha-1) than other RDF levels. With increased RDF levels, there was increase in net returns. But net returns increased significantly up to 100% RDF levels. Similar trend of plant cane was reported in ratoon cane also for cane yield and economics.
