| dc.description.abstract | The present investigation was undertaken to study the “Fertigation Management in Potato (Solanum tuberosum L.) under Tarai conditions of Uttarakhand” at Vegetable Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) during rabi season of 2016-17 and 2017-18. The experiment was laid out in Three Factorial Randomized Block Design (FRBD) with one extra treatment consisting of two fertigation system viz., S1 (surface fertigation) and S2 (sub-surface fertigation), three fertigation scheduling viz., L1 (15% N:10% P2O5: 10% K2O of RDF between 15-30 days after planting (DAP), 40% N, P2O5 and K2O of RDF between 30-45 DAP, 40% N, P2O5 and K2O of RDF between 45-60 DAP, 15% N, 10% P2O5 and 10% K2O of RDF between 60-75 DAP), L2 (25% N, P2O5 and K2O of RDF between 15-30 DAP, 30-45 DAP, 46-60 DAT and 60-75 DAP) and L3 (20% N, P2O5 and K2O of RDF between 15-30 DAP, 30% N, P2O5 and K2O of RDF between 30-45 DAP, 30% N, P2O5 and K2O of RDF between 45-60 DAP and 20% N, P2O5 and K2O % of RDF between 60-75 DAP) and six fertigation treatment viz., T1 (120% of RDF), T2 (100% of RDF), T3 (80% of RDF), T4 (60% of RDF), T5 (40% of RDF), T6 (without fertilizer) along with one an additional treatment T7 (farmers practice) replicated thrice, During the study, various observations on growth parameters, various yield and yield attributing parameters along with quality parameters, nutrient uptake and water use efficiency was also recorded. Besides this, to assess the profitability of different treatment combinations, cost of cultivation, net return was also worked out. The findings of two year investigation revealed that performance of potato was significantly influenced by different fertigation system, fertigation scheduling and fertigation treatment. Among fertigation system, sub-surface system was found superior, among the three fertigation scheduling, schedule 3 was found better and among fertigation treatment, T1 : 120% of RDF was found best in terms of various growth, quality parameters, nutrient uptake in plant, water use efficiency and marketable yield (355.12 and 388.57 q ha-1), net return (`190623 and ` 222400). Based on the overall performance, it could be concluded that under tarai conditions of Uttarakhand, application of sub-surface fertigation @ 192: 120: 144 kg N, P2O5 and K2O per ha through schedule L3 (20: 30: 30: 20% N, P2O5 and K2O of RDF at 15-30: 30-45: 45-60: 60-75 DAP) gave maximum tuber yield and net return with water saving of 68.6% in potato. Hence, the same may be recommended for commercial cultivation. | en_US |
