To assess the response of various organic nutrient sources in brinjal cultivation, an experiment was conducted at the Organic Block of the Research Farm, Department of Vegetable Science, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (HP). The experiment was laid out using a Randomized Block Design with three replications and eight treatments: T1 – absolute control, T2 – farmyard manure (FYM) @ 10 t/ha, T3 – vermicompost (VC) @ 5 t/ha, T4 – FYM @ 5 t/ha + VC @ 2.5 t/ha, T5 – Beejamrit + Jeevamrit, T6 – FYM @ 10 t/ha + Beejamrit + Jeevamrit, T7 – VC @ 5 t/ha + Beejamrit + Jeevamrit, and T8 – FYM @ 5 t/ha + VC @ 2.5 t/ha + Beejamrit + Jeevamrit. Among the different organic treatments, T7 outperformed others in most of the yield and yield-contributing traits and also showed the lowest incidence of insect pests and diseases. The maximum fruit breadth, fruit weight, and marketable fruit yield were recorded under T7. However, in terms of quality parameters, T8 recorded the highest ascorbic acid content and total soluble solids (TSS), which were statistically at par with T7. Therefore, the application of vermicompost @ 5 t/ha along with Beejamrit (as seed treatment) and Jeevamrit (as soil drench and foliar spray @ 5%) can be recommended for improved growth, higher yield, reduced pest and disease incidence, and sustainable crop production under changing climatic conditions.
