Effect of Integrated Method of Nitrogen Application on Growth and Yield of Potato (Solanum tuberosum L. var. Kufri Jyoti) in Mid-Hill of Garhwal

Abstract

An experiment was conducted at the Vegetable Demonstration and Research Block, Department of Vegetable Science, College of Horticulture, VCSG Uttarakhand University Horticulture and Forestry, Bharsar, during summer season; to study the effect of integrated method of nitrogen application through different method i.e. foliar, top dress and basal dose. The experiment was under taken ten treatment combinations of nitrogen level with application method consisting of RDF basal, topdress (100%, 25%, 50%, 75%) and foliar application (1%, 0.25%, 0.50%, 0.75%) were evaluated in randomized complete block design with three replications. Results showed that among the all the treatment nitrogen application T4 (50% recommended dose of N as basal+50% top dress at 30 and 45 DAP) found to be most effective in term of plant height, total number of stems per plant, number of haulms per plant (at 45, 60, 75 DAP and de-haulming), tuber diameter, tuber length and yield.
