Effect of nano fertilizers on growth and yield of tomato (Solanum lycopersicum L.)

The present investigation entitled “Effect of nano fertilizers on growth and yield of tomato (Solanum lycopersicum L.)” was carried out in open field conditions during rabi season in the year 2023-2024 at Centre of Excellence fruits, Mulugu, Siddipet district. The experiment was carried out with seven (7) treatments in Randomized Block Design in three (3) replications i.e. T1: 100% RDF Control, T2: 75% RDF +nano NPK@5 ml/L, T3: 75% RDF +nano [email protected] ml/L, T4: 75%RDF +nano NPK@10 ml/L, T5: 50% RDF +nano NPK@10 ml/L, T6: 50% RDF +nano NPK@15 ml/L, T7: 50% RDF +nano NPK@20 ml/L. The results on growth parameters indicated that among all treatments, T4: 75%RDF +nano NPK@10 ml/L recorded significantly maximum plant height (65.10, 74.45, 85.62 cm), maximum number of compound leaves per plant (24.45, 24.70, 25.13), maximum number of primary branches per plant (10.66, 13.62, 14.13) at 45, 90 DAT and at last harvest respectively compared to the other treatments. The results on yield parameters revealed that significantly maximum fruit length (4.69 cm), maximum average fruit diameter (5.66 cm), maximum average fruit weight (66.20 g) minimum number of days taken to first fruit set (32.46 days), minimum number of days for first harvest (54.20 days), maximum number of fruits per cluster (6.30), maximum number of fruits per plant (15.66), maximum fruit yield per plant (2.86 kg), maximum fruit yield per plot (18.50 kg), maximum fruit yield per hectare (31.38 t) were recorded in the treatment T4: 75%RDF +nano NPK@10 ml/L compared to the other treatments
