Nutrient acquisition of sugarcane planted through single eye budded settling as influenced by integrated nutrient management under south Gujarat condition

An experiment was conducted for three consecutive years 2021-22, 2022-23 and 2023-24 at the Main Sugarcane Research Station Farm, Navsari Agricultural University, Navsari, to study the effect of nutrient management on sugarcane planted through single eye budded settling under South Gujarat conditions. The experiment consisted of 16 treatments laid out in a factorial randomized block design with three replications. The experiment consisted of two levels of organic manure, 25 t/ha FYM (M1) and 15 t/ha bio compost (M2); four levels of recommended dose of fertilizers, 75% of RDF (F1), 100% of RDF (F2), 125% of RDF (F3), 150% of RDF (F4); and two levels of bio-fertilizer, without (B1) and with bio fertilizers (B2) (Acetobacter + PSB+ KMB applied two times as basal and before final Earthing up @ 2.5 l/ha each both time). Based on the pooled analysis of the three-year study, it can be concluded that cane yield, available N, P, and K status of soil, soil properties, and uptake of major nutrients of sugarcane were not significantly affected by different nutrient management practices. Application of FYM@ 25 t/ha or biocompost 15 t/ha and application of fertilizer @188-94-94 kg N-P2O5-K2O/ha with biofertilizer were found to be superior for saving 25% fertilizer dose.
