An experiment entitled on Effect of Nano micronutrients and Nano PGPR_s through Bio capsules on growth and development, yield of Chilli (capsicum annuum l.) cv. Pusa Jwala was conducted during Rabi season of 2022 – 2023 and 2023- 2024 at Crop Research Farm, Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom University of Agriculture, Technology and Science, Prayagraj (U.P.) India. Three levels of Micronutrient like Nano-iron oxide (FeO, 100 ppm), Nano-zinc oxide (ZnO, 150 ppm) and Nano-PGPR Bio capsules: 500 ppm and 250 ppm, containing beneficial bacteria (e.g., Bacillus spp., Azospirillum spp.) encapsulated in biodegradable matrices (e.g., chitosan-based). The sandy loamy soil in the experimental plot had a pH of (7.3), was almost neutral in soil reaction, and had a low organic carbon content of (0.45%), potassium (243.8 kg/ha) and available phosphorus (27.4 kg/ha) nitrogen (239.5 kg/ha). The experiment was laid out in a Randomized Block Design with ten treatments which have replicated thrice. The results revealed that significantly higher growth attributes in year 2022-2023 of Chilli at 120 DAS viz., plant height (96.10 cm), Number of leaves/plant (143.76),and Number of branches/plant, 50% Flower/plant (52.2), Fruit/plant (56.37) Fruit yield (27.01 t/ha) and TSS Brix 7.35%) were recorded in T₁₄ (T₁₄-NPK(RDF)100%, Biocapsule 250PPM + ZnO + FeO) compared to other treatments. and result showed in 2023-2024 of Chilli at 120 DAS viz., plant height (89.47cm), Number of leaves/plant (147.05), and Number of branches/plant, 50% Flower/plant (51.5), Fruit/plant (58.64) Fruit yield (28.61 t/ha) and TSS Brix% (7.06%) were recorded in T₁₄ (T₁₄-NPK(RDF)100%Biocapsule 250PPM + ZnO + FeO) compared to other treatments was recorded the best among all combination, different hybrid in terms of growth, yield and quality parameters
