Abstract
Continuous depletion of micronutrients from soil through modernized agricultural practices emerged as major impediment to achieve the goal of sustainable agriculture. Therefore, the effect of B, Mo fertilization supplemented with NPK sources and vermicompost on the growth of brinjal crop have been studied during 2021–2022 and 2022–2023. Field experiments were conducted under randomized block design with eight treatments replicated thrice comprised of different B, Mo doses supplemented with NPK sources and vermicompost. Application of B and Mo up to 2.25 and 1.5 kg/ha significantly influenced the biological yield of crop. Maximum plant height (84.4 cm), fruit length (17.5 cm), ascorbic acid (7.71 mg/100 g), leaf/plant (84.4), leaf area (2439.15 cm2), fruit count/cluster (3.61), and fruit boron (0.70 mg/100 g), was recorded under treatment of 100% NPK + 2.25 kg/ha B + 1.5 kg/ha Mo + 10 t/ha vermicompost (T6). Pooled data showed a maximum uptake of N, P, and K in range 90.6, 27.9, and 63.8 kg/ha under same treatment. In addition, similar treatment clinched maximum yield of 25.5 followed by 23.7 t/ha under T7. Results on growth characters and yield were found comparable in 2022–2023 over 2021–2022. However, B (1.5) and Mo (1 kg/ha) incorporated with 75% RDF NPK and vermicompost (7.5 t/ha) showed superior results with higher yield as compared to sole application of NPK. The study identified B and Mo (2.25 and 1.5 kg/ha) + 100% RDF NPK and vermicompost (10 t/ha) as best and prominent treatment with highest production potential and maximum crop growth.
