Effect of Humic Acid and Nutrients Mixture on Growth and Yield Parameter on Tomato (Lycopersicon esculentum Mill.) Under Polyhouse Condition

Adoption of greenhouse technology can improve yield and productivity of tomato crop in off season cultivation. An experimentwas conducted inpolyhouse house at Rajasthan College of Agriculture, Udaipur (Raj.) to determine the Effect of humic acid and nutrients mixture on growth and yield parameter of Tomato (Lycopersicon esculentum Mill.) under polyhouse condition. The data was analyzed statistically following completely randomized design. The results revealed that treatment T₇[(RDF + humic acid 10 kg/ha soil application + humic acid 0.1% foliar spray + nutrient mixture foliar spray (0.2% Ca + 0.5% Mg + 0.2% B + 0.5% Zn)] was found significantly superior to enhance plant height (282.50 cm), number of branch per plant (8.82), leaf area (327.60 cm²), fruit weight (82.60 g), cluster per plant (10.40), number of fruit per cluster (8.20), yield per plant (6.99 kg), yield per square meter (27.96 kg).
