Response of integrated nutrient management practices on growth and tuber yield of potato crop (Solanum tuberosum L.) in clay soils of Punjab

Abstract

Toinvestigate the response of integrated nutrient management (INM) practices on growth and tuber yield of potato crop (Solanum tuberosum L.) in clay soils of Punjab was conducted during rabi season of 2017-18 at the Campus for Agricultural Research and Advanced Studies Dhablan of the G.S.S.D.G.S. Khalsa College Patiala, Punjab. The field experiment was laid out in randomized block design with 13 different treatments with 3 replications. Integrated nutrient management significantly influenced the growth and tuber yield of potato crop. All the growth parameters like plant height (cm), number of branches plant-1, fresh weight plant-1and tuber yield (200.26 q ha-1) was significantly higher in treatment T7with 100% RDF + 2t Poultry manure ha-1 + 20kg S ha-1 + 20kg ZnSO4 ha-1 + 1t vermicompost ha-1 + Azotobacter which was followed by treatment T6 with 100% RDF + 2t Poultry manure ha-1 + 20kg S ha-1 + 20kg ZnSO4 ha-1 + 1t vermicompost ha-1.
