Integrated soil amendments for potato crop performance

Present study on integrated soil amendments for potato crop performance was conducted at the Horticultural Research Farm of Chaudhary Shivnath Singh Shandilya (P.G.) College, Machhra, Meerut (U.P.) during rabi season of the year 2020-21. The experiment was laid out in RBD (Randomized Block Design) with nine treatments consisting of different organic and inorganic fertilizers, both alone and in combination, replicated thrice. Observations on growth parameters at 60 and 90 days after planting (DAP), yield parameters at the time of harvest and quality parameters after harvest were recorded for statistical analysis. The result obtained indicated superiority of combinations of inorganic and organic fertilizers as compared to the other treatments in terms of growth and yield parameters. The maximum plant height, greater number of leaves per hill and greater tuber diameter were observed with treatment receiving half of the recommended dose of fertilizers (RDF) and 20 t/ha FYM, while the maximum number of haulms per hill and higher dry matter content was observed in treatment receiving 5 t/ha vermicompost. More number of branches per plant, yield characters i.e., number of tubers/ plant, weight of tuber, average tuber weight, and yield of tuber were recorded in treatment receiving full RDF along with 5 t/ha vermicompost.
