Effect of Foliar Application of Zinc and Manganese on Growth Parameters and Yield of Potato (Solanum tuberosum L.)

Abstract

An experiment was conducted during Rabi season 2018 at the Department of Agriculture, Mata Gujri College, Fatehgarh Sahib, Punjab, India. The experiment was laid out in a randomized block design with three replications. The treatments consisted of foliar application of different combinations of zinc, manganese and farm yard manure which increased the growth and yield in potato. The maximum plant height (41.17 cm at 45 DAP) and (47.67 cm at 90 DAP), numbers of leaves (36.50 at 45 DAP) and (50.40 at 90 DAP), number of shoots per hill (6.54), leaf area index (1.29). The maximum number of tuber per plant (9.17), Tuber yield per plant (647.67g), tuber yield per plot (14.58 kg), tuber yield per hectare (364.42q), marketable yield per hectare (362.92q), unmarketable yield per hectare (1.50 q), were recorded with the application of (recommended dose of NPK + Farm Yard Manure 50 % +Zinc @ 4 kg ha-1 + Manganese @ 2.4 kg ha-1). These results suggested that the optimum production of potato can be obtained with application of (NPK 100 %+ FYM 50% +Zn @ 4 kg ha-1 + Mn @ 2.4 kg ha-1).
