Effect of growth parameters as influenced by nutrient sources of Potato (Solanum tuberosum L.)

摘要: The present investigation entitled Effect of growth parameters as influenced by nutrient sources of potato (Solanum tuberosum L.) was carried out in Horticulture Research cum Instructional Farm of Barrister Thakur Chhedilal College of Agriculture and Research Station, Sarkanda, Bilaspur (CG), during Rabi season of Nov 2018 to Mar 2019, The field experiment was laid out in randomized block design with 3 replications and 12 different treatment combinations viz. T1 (125% RDF (187: 125: 125 kg ha-1 NPK), T2 (100% RDF (150: 100: 100 kg ha-1 NPK), T3 (75% RDF+ FYM@ 7.5 t ha-1 (25% N by FYM), T4 (50% RDF+ FYM@ 15 t ha-1 (50% N by FYM), T5 (75% RDF+ Vermicompost@ 3.75 t ha-1 (25% N by Vermicompost), T6 (50% RDF+ Vermicompost@ 7.5 t ha-1 (50% N by Vermicompost), T7 (Tuber treatment with Trichoderma@ 20 g/k+ soil incorporation of Trichoderma enriched FYM@ 15 t ha-1 SOIL, T8 (Tuber treatment with Pseudomonas@ 20 g/k+ soil incorporation of Pseudomonas enriched FYM@ 15 t ha-1 soil, T9 (Tuber treatment with Pseudomonas followed by Trichoderma@ 20 g/k+ soil incorporation of consortia of Pseudomonas & Trichoderma enriched FYM@ 15 t ha-1 soil, T10 (Tuber treatment with consortia of Azotobacter & PSB@ 20 g/k+ soil incorporation of consortia of Azotobacter & PSB enriched FYM@ 15 t ha-1 soil, T11 (50% RDF only FYM@ 15 t ha-1 (50% N by FYM) and T12 (Local control). Integrated use of synthetic fertilizers and organic manures showed the significant impact on growth of potato. Among the different treatments, application of T6-(50% RDF+ Vermicompost@ 7.5 t ha-1 (50% N by Vermicompost) had …
