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 Himachal PrEnglishThesis
