摘要

Potatoes have received a reputation as being a large consumer of nutrients such as nitrogen (N), phosphorus (P) and potassium (K). An experiment was conducted to study the effect of integrated nutrient management on the dry matter accumulation and uptake of nutrients in potato (Solanum tuberosum L.). Application of 50% RDF+50% FYM+Azotobacter+Phosphobacteria (T7) recorded maximum total dry matter production (21.67%) which was at par with T3 (20.53%) and followed by T4 (19.79%), T5 (19.19%), T9 (18.55%) and T6 (18.42) during rabi 2011. Similarly, the maximum uptake of N (97.17 kg/ha), P (21.76 kg/ha) and K (159.63 kg/ha) was found with plants provided with 50% RDF+50% FYM+Azotobacter+PSB (T7) which was at par with T4, T3 and T5 during rabi 2011. The minimum dry matter accumulation (15.32%) and N (83.40 kg/ha), P (16.13 kg/ha) and K (108.23 kg/ha) were registered with 100% FYM+50% N supplied through neem cake+Azotobacter (T8).
