Abstract:
The present investigation was carried during the kharif 2019-20 at Indira Gandhi Krishi Vishwavidyalaya- College of Agriculture and Research Station, Jagdalpur, Bastar (Chhattisgarh). The experiment was laid out in a factorial randomized complete block design with sixteen treatment combinations consisted of four levels of fertilizers (N₀P₀K₀, N₅₀P₄₀K₅₀, N₇₅P₆₀K₇₅ and N₁₀₀P₈₀K₁₀₀) and four levels of Farm Yard Manure (0, 10, 20 and 30 t ha^-1). The result revealed that the plant height, leaf area index, length of corm, width of corm, weight of corm plant^-1, dry matter (%) of tuber and tuber yield increased significantly at each level of fertilizer. The plant height and leaf area index at 3 month after planting, length of corm, weight of corm plant^-1, dry matter (%), tuber yield, increased significantly at each level of FYM, however, the plant height and leaf area index at 5 month after planting and width of corm, responded significantly up to FYM @ 20t ha^-1. The weight of corm was not influenced significantly with the FYM levels under N₀P₀K_0, and N₁₀₀P₈₀K₁₀₀ (except FYM @ 10t ha^-1) and it responded to each successive level of FYM under remaining two fertilizer doses. The successive doses of FYM were significantly responded by tuber yield under all the fertilizer doses except FYM @10 t ha^-1 under N₀P₀K₀. It shows that the dose of FYM @10 t ha^-1 might not be sufficient to improve the tuber yield significantly where no fertilizer was applied. The fertilizer dose @ N₁₀₀P₈₀K₁₀₀ kg ha^-1 in conjunction with FYM @ 30t ha^-1 was found better in terms of higher tuber yield (35.1 t ha^-1) of Bunda.
