Abstract:
A field experiment was laid out at AICRP on Tuber Crops, Regional Horticultural Research Station (RHRS), Navsari Agricultural University, Navsari on sweet potato cv. Bhukanti during Rabi, 2017-18. The experiment was arranged over 12 treatment combinations comprising, 3 levels of RDF (F1: 100% RDF, F2: 80% RDF and F3: 60% RDF) and 4 levels of spraying 2% Novel (S1: No spray, S2: spraying 2% Novel at 30 and 45 DAP, S3: Spraying 2% Novel at 30, 45 and 60 DAP and S4: spraying 2% Novel at 30, 45, 60 and 75 DAP) which was laid out in a randomized block design (with factorial concept) and replicated thrice. Application of 100% RDF (F1) recorded higher average tuber weight of 186.87 g with minimum number of tuberous roots (3.03) and statistically remained at par with F2 treatment. Other yield parameters did not show significant effect due to different levels of fertilizers. Maximum tuber yield (0.513 kg vine-1) and average tuber weight (189.69 g) was obtained in S4 treatment (spraying 2% Novel at 30, 45, 60 and 75 DAP) and statistically remained at par with S3 treatment. Significantly higher total tuber yield (5.872 kg net plot-1 and 30.58 t ha-1), marketable tuber yield (4.867 kg net plot-1 and 25.35 t ha-1), and harvest index (46.14%) with lower number of tuberous roots (2.92) was recorded in the S4 treatment. F1 and S4 treatments recorded higher total sugars content of 2.62 per cent and 2.64 per cent, respectively.
