Effect of Organic Nutrient Sources on Growth, Seed Yield and Seed Quality of Radish (Raphanus sativus L.) cv. Chinese Pink

Abstract

Seed is the ultimate economic input in any crop production programme. Two field experiments were conducted to study the effect of organic inputs on seed production of radish at Organic Block of Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Rabi season of 2019-20 & 2020-21. Various combinations of organic and liquid manures were replicated thrice in the form of twelve treatments in Randomized Block Design (RBD) Factorial. The pooled data of two years revealed that treatment with Vermicompost @ 8 t/ha + Jeevamrit @ 10 per cent was rated as best treatment for majority of characters like days to 50 per cent initiation of bolting (61.00), days to 50 per cent flowering (93.33), number of primary branches per plant (11.13), plant height (171.50 cm), pod length (5.82 cm), number of seeds per pod (5.01), seed yield per plot (225.25 g) & hectare (417.13 kg) and seed quality parameters like 1000 seed weight (12.02 g), seed germination (97.03 %), seedling length (28.26 cm), seedling dry weight (8.87 mg), seed vigour index-I (2742.07) and seed vigour index-II (860.42). Vermicompost along with jeevamrit recorded 61.41 per cent increase in yield over control. Hence application of vermicompost @ 8 t/ha + jeevamrit @ 10 per cent can be recommended for getting higher seed yield and better growth for organic seed production of radish.
