ABSTRACT
The present investigation titled “Studies on the Effect of Organic Nutrient Sources on Yield
and Quality of Bridal (Solanum melongena L.)” was carried out at Organic block of the Department
of Vegetable Science, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan HP
during Kharif season of 2019. The experiment was laid out in Randomized Complete Block Design
(RCBD) with three replications comprising of eight treatment. The treatments were T1: Absolute
control, T2: FYM @ 10 t/ha, T3 : VC@ 5 t/ha, T4 : FYM @5 t/ha + VC@2.5 t/ha, T5: Beejamrit (Seed
treatment) + Jeevamrit (Drenchings + Foliar spray), T6 :FYM @10 t/ha + Beejamrit (Seed treatment)
+ Jeevamrit (Drenchings + Foliar spray), T7: VC @5 t/ha + Beejamrit (Seed treatment) + Jeevamrit
(Drenchings + Foliar spray), T8 : FYM @ 5t/ha + VC @2.5 t/ha + Beejamrit (Seed treatment) +
Jeevamrit (Drenchings + Foliar spray). The seeds of brinjal cv. Pusa Purple Cluster were sown in the
nursery beds on 27th March, 2019 and the seedlings were transplanted on 11thMay, 2019. The plot size
was 2.40 m × 2.25 m and a spacing of 60 cm × 45 cm was followed. Amongdifferent organic nutrient
sources application of vermicompost along with beejamrit and jeevamrit performed best for most of
the yield and yield contributing traits as well as less pest and diseases incidence. The combined
application of vermicompost along with beejamrit and jeevamrit (T7) significantly influenced growth
and yield attributes of brinjal and resulted significantly maximum number of fruits per plant (23.22),
fruit breadth (4.25 cm), average fruit weight (46.18 g), marketable fruit yield (173.36 q/ha) and plant
biomass (2,084.94 kg/ha) whereas, plant height (75.52 cm) was found maximum in T3 (VC @ 5t/ha).
However, FYM @ 5t/ha + VC @2.5 t/ha along with beejamrit and jeevamrit recorded highest
ascorbic acid content (26.73 mg/100g) and TSS (4.74°B). Vermicompost @ 5t/ha along with
beejamrit and jeevamrit recorded (45.98) per cent increase in yield over control along with increase in
soil available NPK contents, total NPK content in plantand less incidence of pest and diseases besides
highest net return (Rs 2,00,200/ha). Hence, application of vermicompost @ 5t/ha along with beejamrit
andjeevamrit for retention of soil fertilityand getting better growth, high yield, least pest and diseases
incidence can be recommended for commercial cultivation of brinjal.
