ABSTRACT
The present investigation entitled “Studies on effect of intercropping and manurial practices on
and quality of brinjal (Solanum melongena L.)” was carried out at Experimental Farm and Quality Analysis
Laboratory, Department of Vegetable Science, Dr Yashwant Singh Parmar University of Horticulture
and Forestry, (Nauni) Solan (HP) during Kharif 2021. The experiment was conducted on main crop brinjal
var. Pusa Purple Long and intercrops maize var. Local Selection and okra var. P-8 which was laid out in
Randomized Complete Block Design with three replications, comprising of seven treatments viz. T1: Brinjal
intercropped with Maize + FYM, T2: Brinjal intercropped with Maize + FYM + Beejamrit + Ghanjeevamrit +
Jeevamrit, T3: Brinjal intercropped with Maize + FYM + RDF, T4: Brinjal intercropped with Okra + FYM, T5:
Brinjal intercropped with Okra + FYM + Beejamrit + Ghanjeevamrit + Jeevamrit, T6: Brinjal intercropped with
Okra + FYM + RDF and T7 (Control): Brinjal sole crop + FYM + RDF. Analysis of variance showed
significant variations for effect of intercropping and manurial practices on most of the parameters studied.
Among different treatments, sole brinjal + FYM + RDF (T7) recorded maximum number of fruits per plant
(10.15), fruit length (22.43 cm), fruit breadth (3.09 cm), fruit weight (100.84 g), fruit volume (104.66 cc),
numbers of leaves per plant (149.00), plant spread (70.71 cm), plant height (72.99 cm), number of branches per
plant (4.60), stem girth (5.47 cm), yield of brinjal per plant (1065.67 g) and projected per hectare (276.24 q)
which were statistically at par with brinjal intercropped with okra + FYM + RDF (T6). The treatment T6
performed best in yield of intercrops [per plant (322.07 g) & projected per hectare (41.75 q)] and total brinjal
and brinjal equivalent yield [per plant (1375.40 g) & projected per hectare (314.75 q)] which was statistically at
par with brinjal intercropped with okra + Beejamrit + Ghanjeevamrit + Jeevamrit (T5) which also recorded
maximum TSS (6.97 oB), fruit flesh density (0.99 g/cc), ascorbic acid content (15.46 mg/100g) and minimum
days to 50% flowering (44.67), fruit borer infestation (10.05%), shoot borer infestation (8.96 %) and fruit borer
incidence (9.36%). From the present investigation, it can be concluded that brinjal cv. Pusa Purple Long
intercropped with okra and application of recommended doses of manures and fertilizers (100 q/ha FYM + 50
kg N/ha + 60 kg P2O5/ha + 45 kg K2O/ha) gave the highest yield of brinjal (273.00 q/ha) and okra (41.75 q/ha)
along with maximum net returns per hectare (` 3,99,955) and B:C ratio (1.74) followed by brinjal intercropped
with okra + 100 q/ha FYM + Beejamrit + Ghanjeevamrit + Jeevamrit gave yield of brinjal 245.69 q/ha and
okra 41.48 q/ha along with net returns per hectare ` 3,49,505 and B:C ratio 1.55 under mid hill conditions of
