ABSTRACT
The present investigation titled “Studies on Organic Seed Production in Radish” was
carried out 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. Various combinations of
organic and liquid manures were replicated thrice in the form of twelve treatments combinations of
four levels of organic manure viz. M0 (No manure), M1 (FYM @ 20 t/ha), M2 (Vermicompost @ 8
t/ha), M3 (FYM @ 10 t/ha + Vermicompost @ 4 t/ha) and three levels of liquid manure viz. J0 (No
Jeevamrit), J1 (Jeevamrit application @ 5 %) and J2 (Jeevamrit application @ 10 %). The experiment
was laid out in a Randomized Block Design (RBD) Factorial involving plot size of 2.4 × 1.8 m and
spacing of 60 × 30 cm. The seeds of radish cv. Chinese Pink were sown on 20th September, 2019 and
two months old roots were uprooted for prepration of stecklings. The stecklings of radish were
replanted on 11th November, 2019. The results revealed that treatment T9 (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, days to 50 per cent flowering, number of primary branches per plant, plant
height, pod length, number of seeds per pod, seed yield per plot and hectare, 1000 seed weight, seed
germination, seedling length, seedling dry weight, seed vigour index-I, seed vigour index-II, available
NPK in soil and disease severityof white rust. Vermicompost along with jeevamrit recorded 62.66 per
cent increase in yield over control along with increase in soil available NPK content and less severity
of white rust. Besides this, the highest net returns were recorded` 2,77,536/ha for the same
treatment. Hence application of vermicompost @ 8 t/ha + jeevamrit @ 10 per cent can be
recommended for getting higher seed yield, better growth, less severity of disease and better nutrient
status of soil for organic seed production of radish.
