Standardization of date of planting and INM package to optimize yield in Rabi potato

Abstract

The field experiment was carried out at Experimental Field of the Division of Vegetable Science, Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, Shalimar, Srinagar for two consecutive years (2018-2019) to identify the suitable time of planting and nutrient management for optimal yield of rabi potato under temperate valley of Kashmir. The experiment consisted of the treatments which were a combination of four planting dates viz; D1 (Ist fortnight of july), D2 (2nd fortnight of july), D3 (Ist fortnight of august), D4 (2nd fortnight of august) and seven combinations of organic and inorganic nutrients viz; T1 (RFD i.e 160:100:100), T2 (75% RFD + 25% Vermicompost), T3 (75% RFD + 25% FYM), T4 (50% RFD + 50% Vermicompost), T5 (50% RFD + 50% FYM), T6 (50% RFD + 25% Vermicompost + 25% FYM) and T7 (Control).The observations were recorded and among different dates of planting and nutrient management, planting on D2 (2nd fortnight of july) with nutrient combination of T6 (50% RFD + 25% Vermicompost + 25% FYM) showed best tuber yield.
