Abstract
ABSTRACT
A total of thirteen treatment combinations arranged in a complete randomized design and were replicated three times for both, tomato and capsicum in the net house of the Department of Soil Science & Water Management, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh, during the years 2020 and 2021. The application of foliar spray of ZnO @ 50 ppm + 50 % RDN (through vermicompost) + 50 % RDN (through chemical fertilizers) increased the plant height (216.33 and 72.00 cm) with 18.1 and 64.9 % increase over control, root length (28.17 and 14.85 cm), number of primary branches (6.67 and 5.67), plant biomass (172.67 and 87.00 g), number of fruits per plant (22 and 19), fruit yield (1.61 and 1.48 kg), chlorophyll a (0.54 and 0.82 mg g-1), chlorophyll b (1.01 and 1.54 mg g-1), N uptake (5.85 and 2.87 g plant-1), P uptake (1.18 and 1.22 g plant-1) and K uptake (7.63 and 9.35 g plant-1) for tomato and capsicum, respectively. The maximum benefit cost ratio (3.71 and 3.44) of tomato and capsicum was also recorded under treatment with conjoint application of vermicompost and chemical fertilizers along with foliar spray of 50 ppm ZnO nano-particles. Moreover, ZnO nano-particles application @ 50 ppm (seed treatment) in combination with vermicompost and chemical fertilizers increased available nutrient status, soil enzymes (dehydrogenase, phosphatase and urease) and other microbiological properties (viable microbial count and microbial biomass) of soil. Overall, the application of 50 ppm ZnO nano-particles concentration through seed treatment and foliar spray improved the soil properties, plant growth and quality parameters of tomato and capsicum and the above-mentioned nutrient module may be recommended after carrying out multi-locational trials in Himachal Pradesh for adoption of nanoparticles in the agricultural fields.
