Abstract: The present investigation was aimed to determine the “Co-inoculation effect of Vermicompost & Plant Growth Promoting Rhizobacteria on the growth of chilli (Capsicum annuum)” by pot experiment method, which was carried out in green house of School of Forestry. The growth parameters selected for study were Plant height, Root length (cm), Number of leaves/plant, Number of branches/plant, Number of fruits/plant and Weight of fruit (g). Vermicompost were produced by Earthworms species, (Lumbricus rubellus) on vegetable waste. The experiment was conducted in Completely Randomized Design (CRD) with 6 replications. The treatment comprised of T₀: (Normal seed without any amendment), T_1: Vermicompost (1kg), T_2: 100% Recommended dose of NPK_, T₃: PGPR (Azotobacter sp.) treated seed_, T₄: Vermicompost (1kg) + PGPR (Azotobacter sp.) treated seed, T₅: Vermicompost (1kg)+ 50% Recommended dose of NPK +PGPR (Azotobacter sp.) treated seed. The treatment T₅ Vermicompost (1kg) + 50% Recommended dose of NPK +PGPR (Azotobacter sp.) treated seed. showed significantly the best result in plant height (151 cm), number of leaves/plant(330), number of branches/plant(82.40), number of fruits/plant (8.33), weight of fruits/plant (g) (2.75 gm), root length (cm)(17.50cm) followed by T4 Vermicompost(1kg)+ PGPR (Azotobacter sp.) treated seed, when compared with other treatments. Azotobacter sp. was shown to be a plant growth promoting agent for (Capsicum annuum). Hence, major research focus should be on the production of efficient and sustainable bio-fertilizers for crop plants, where inorganic fertilizer application can be reduced significantly to improve soil health.
