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. Juice extraction per cent, brix value, pol %, purity %, fibre % and juice pH did not differ significantly for RDF levels, cultivar and interaction effects in both plant and ratoon cane. The reducing sugars in juice differed significantly due to different cultivars in both plant and ratoon cane. The Cultivar SNK 635 recorded significantly lower reducing sugars (3.14 and 3.22 %, respectively in plant and ratoon cane) than Konanakatte (3.55 and 3.66 %, respectively in plant and ratoon cane) but on par with Co-86032 (3.27 and 3.32%, respectively in plant and ratoon cane). Higher reducing sugar was recorded in cultivar Konanakatte (3.50 and 3.66 %, respectively in plant and ratoon cane). There was decreased reducing sugars with decreased levels of fertilizers. Application of 75% RDF recorded significantly lower reducing sugars (3.01 and 3.07 %, respectively in plant and ratoon cane) and on par with 100 % (3.14 and 3.18 %, respectively in plant and ratoon cane). Similar trend of juice quality was reported in liquid jaggery also for reducing sugars content.
