Effect of foliar application of secondary and micronutrients on quality of potato

Abstract

The experiment conducted on effect of foliar application of secondary and micronutrients on potato quality was carried out at the Instructional Farm, Faculty of Horticulture of Uttar Banga Krishi Vishwavidyalaya, Pundibari, Cooch Behar during rabi season of 2017-2018. The experiment was laid out in Randomized Block Design with three replications comprising 16 treatments for foliar application of different sole and combined foliar application of secondary and micro nutrients. Result reveled that all the quality parameters were improved significantly. Highest dry matter content in the tubers was 16.81 per cent, Maximum total carbohydrate content of tubers was 46.25, The highest starch content (per cent) of tubers was 18.78, Maximum Reducing and total sugars of tubers were 0.32 and 0.79 was recorded with the foliar application of Magnesium (Mg), sulphur (S), zinc (Zn) and boron (B). But TSS of tubers was not significantly affected.
