Integrated nitrogen management in okra under Tarai conditions of Uttarakhand

Abstract

The present investigation carried out to examine the effect of on growth and yield of okra at Vegetable Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar, Udham Singh Nagar, Uttarakhand in summer seasons of 2016 and 2017 with fourteen treatments containing different combinations of organic and inorganic sources of nitrogen replicated thrice. Observations for growth parameters viz., plant height, stem diameter and number of leaves per plant at different growth stages of plants, leaf area index and the total marketable yield of green pods were recorded. The findings of two year investigation revealed that the performance of okra crop was significantly influenced by various treatments. Among all treatments, treatment T6 (RDN- 75% through neem coated urea + 25% through vermi-compost) was found best with respect to plant growth and yield and hence, recommended for obtaining higher yield of okra under prevailing climatic conditions of Uttarakhand tarai region.
