ABSTRACT
The present investigation titled “Studies on effect of organic nutrient sources on seed
yield of garden pea (Pisum sativum L.)” was carried out at Vegetable Research Farm,
Department of Vegetable Science, Dr. Y S Parmar University of Horticulture and Forestry,
Nauni, Solan (HP) during Rabi season of 2020-21. The experiment was laid out in Randomized
Complete Block Design (RCBD) with three replications comprising of twelve treatments. The
treatments were M0J0: No manure (Control), M0J1: No manure + Jeevamrit @ 5 % drenching,
M0J2: No manure + Jeevamrit @ 10 % drenching, M1J0: FYM @ 5 t/ha + No jeevamrit, M1J1:
FYM @ 5 t/ha + Jeevamrit @ 5 % drenching, M1J2: FYM @ 5 t/ha + Jeevamrit @ 10 %
drenching, M2J0: FYM @ 10 t/ha + No jeevamrit, M2J1: FYM @ 10 t/ha + Jeevamrit @ 5 %
drenching, M2J2: FYM @ 10 t/ha + Jeevamrit @ 10 % drenching, M3J0: FYM @ 15 t/ha + No
jeevamrit, M3J1: FYM @ 15 t/ha + Jeevamrit @ 5 % drenching, M3J2: FYM @ 15 t/ha +
Jeevamrit @ 10 % drenching. Biofertilizers (Rhizobium + PSB) were applied @ 200 g/10kg as
seed and 5 kg/ha as soil application uniformly to all the treatment combinations. The seeds of
pea cv. Punjab 89 were sown on 21st October, 2020. The plot size was 3 × 2 m and a spacing of
60 × 7.5 cm was followed. The combined application of FYM @ 15t/ha along with jeevamrit @
10 per cent drenching resulted in maximum plant height (cm), pod length (cm), no. of pods per
plant, no. of seeds per pod, gross seed yield, graded seed yield, speed of germination, 100 seed
weight, seed germination (%), organic carbon (%), NPK content, viable microbial count,
highest net returns along with low EC of seed, soil pH & EC and disease incidence. Hence,
application of FYM @ 15 t/ha + jeevamrit @ 10 per cent drenching can be recommended for
getting more seed yield, enhanced soil fertility and maximum net returns in organic seed
production of pea.
