Studies on polymer seed coating with nutrients and pesticides on growth and yield of radish (Raphanus sativus L.)

Abstract

The present investigation entitled “Studies on Polymer Seed Coating with Nutrients and Pesticides on Growth and Yield of Radish (Raphanus sativus L.)” was carried out using cv. Pusa Himani. The experiment was laid out in Randomized Complete Block Design (RCBD) with 15 treatments comprising of different combinations of polymer with nutrients and pesticides, in the Research Farm of Department of Vegetable Science for two years (2016 and 2017). The observations in field were recorded on field emergence (%), days to marketable maturity, number of leaves per plant, top length (cm), leaf length (cm), leaf width (cm), root length (cm), root diameter (mm), gross root weight (g), net root weight (g), root/ top ratio: length basis & weight basis and root yield per plot (kg) and per hectare (q). Analysis of variance showed significant differences among the treatment combinations for all the characters studied. Experimental results revealed that polymer seed coating @10 ml+ NPK (19:19:19) @ 5g+ carbendazim @ 2g+ imidacloprid @ 3ml/kg seed was found superior over all treatments in terms of most of the growth and yield characteristics in both years i.e. 2016 and 2017. Therefore, coating the seeds of radish with polymer @10 ml+ NPK (19:19:19) @ 5g+ carbendazim @ 2g+ imidacloprid @ 3ml/kg seed can be recommended for getting higher yield of radish in Himachal Pradesh after multilocational testing.
