Effect of Traditional Fertilizer, Nano-Fertilizer and Micronutrient on Growth, Yield and Quality of Tomato (Solanum lycopersicum L.)

A trial was conducted at the Vegetable Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology & Sciences, Prayagraj (UP) during 2022. This study investigates the “Effect of traditional fertilizer, nano fertilizer and micronutrient on growth, yield and quality of Tomato (Solanum lycopersicum L.).” The purpose of the study is to evaluate the plants in terms of various parameters such as plant height, survival percentage, days to first flowering, days to 50% flowering, number of flower clusters per plant, number of fruit set per cluster, number of fruits per plant, fruit weight, fruit yield per plant, fruit yield per hectare, total soluble solids (TSS), ascorbic acid, and benefit-cost ratio. The study's findings show that applying more NPK, ZnSO4, and Nano Zinc to the soil dramatically increased tomato growth and yield. The plants treated with 100% NPK + 25% ZnSO4 by the conventional approach + 75% spray through Nano zinc had the maximum fruit yield (135.57 t/ha), fruit weight (88.407 g), TSS (5.36 Brix), and ascorbic acid content (26.4 mg/100g). Additionally, it was discovered that the treated plants' benefit-cost ratio was larger than the control's. Overall, the study indicates that increasing the growth, yield, and quality of tomatoes can be accomplished by applying 100% NPK + 25% ZnSO4 by traditional technique + 75% spray via Nano zinc.
