Abstract:
The present study entitled “Studies on effect of cut and whole seed tubers, plant spacing and different varieties on yield attributes of potato (Solanum tuberosum L.) under Chhattisgarh plains condition” was conducted during rabi season 2019-20 and 2020-21 under All India Coordinated Research Project on Potato, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) This experiment was designed in Factorial Randomized block design had three replications, sixteen treatment combinations, keeping four varieties i.e. V₁: K. Jyoti, V₂: K. Pukhraj, V₃: K. Sindhuri and V₄: K. Neelkanth and four plant spacing i.e. S₁: 10 cm cut seed tuber, S₂: 15 cm cut seed tuber, S₃: 20 cm cut seed tuber and S₄: 20 cm whole seed tuber. To identifying the most suitable high yielder potato varieties under cut and whole seed tuber, also to find out the best combination of plant spacing and potato varieties suitable for the grower of these region. Among the varieties the yield attributes were differ significantly higher the treatment V₃ (K. Sindhuri) given the maximum fresh weight of tuber (199.13 g) and dry weight of tuber (25.16 g) at 90 DAP, were found significantly differ among different varieties. The maximum marketable tuber yield (21.59 t ha^-1), unmarketable tuber yield (1.99 t ha^-1) and total tuber yield (26.01 t ha^-1) were recorded under V₃ (K. Sindhuri) at 90 DAP, all the observations were found significant differences among varieties. The harvest index % was found differ non-significantly among varieties although it was recorded higher with the treatment V₃ (K. Sindhuri).
