Abstract:
The present investigation was carried out at Department of Horticulture, College of Agriculture, Anand Agricultural University, Vaso during Rabi season for the year 2019-20 and 2020-21. The experiment was laid out in randomized block design with factorial concept having fourteen treatment combinations with three replications comprising two factors having two levels of micronutrients and seven levels of INM. Different treatments of INM and micronutrients improved the growth, yield parameters of tomato. Among treatments of micronutrients, Zinc @ 100 ppm recorded significantly maximum plant height (119.86 cm), crop growth rate (60-90 DAT) (7.21 g/m²/day), relative growth rate (30-60 DAT) (71.40 mg/g/m²), relative growth rate (60-90 DAT) (77.33 mg/g/m²). Boron @ 100 ppm recorded significantly minimum days to 50% flowering (35.36), days to first picking (65.38), maximum number of fruits per plant (31.39), fruit yield per plant (2.15 kg), fruit yield per plot (28.83 kg), fruit yield per hectare (39.55 t). Among INM treatments N₅: 50% RDF + 50% N from FYM + Bio NPK recorded significantly maximum plant height (125.97 cm), number of primary branches (7.08), crop growth rate (30-60 DAT) (7.50 g/m²/day), crop growth rate (60-90 DAT) (7.94 g/m²/day), relative growth rate (30-60 DAT) (75.25 mg/g/m²), relative growth rate (60-90 DAT) (76.92 mg/g/m²), harvest index (62.72%), maximum fruit diameter (7.37 cm), fruit weight (86.72 g) and fruit volume (83.02 cc), maximum number of fruits per plant (32.32), fruit yield per plant (2.32 kg), fruit yield per plot (31.03 kg) and fruit yield per hectare (42.57 t) while minimum days to 50% flowering (35.00), days to first picking (66.00) recorded with treatment N6: 50% RDF + 50% N from Vermicompost + Bio NPK. Interaction effect of micronutrient and INM found non-significant for all parameters. Boron @ 100 ppm recorded the highest net realization (Rs. 208925) and BCR (3.1) while among INM treatments, N5: 50% RDF + 50% N from FYM + Bio NPK recorded the highest net realization (Rs. 219552) and BCR (2.8).
