Resumo

Inconsistent distribution of soil nutrients affects cultivation of crops. Therefore, effects of planting depths on vegetative performance and biochemical compositions of tomato fruits were assessed. Seeds of tomato were planted at 2, 4, 6 and 8 inches in a randomized complete block design with four replicates. Vegetative performance, nutritional contents and phytochemical compositions of fruits of the tomato were determined. Least days of emergence (4 days), highest height (71.00 cm), number of leaf (31.30), Leaf area (34.00 m²) and leaf area index (0.80 m²/m²) were higher in tomato plants produced by seeds planted at 4 inches. Net assimilation rate (0.08 gm^-2 day^-1) and leaf area ratio (0.70 m²kg^-1) were higher in tomato planted at the depth. Crude fibre (0.14%), crude protein (0.62%) and fat (0.17%) were also higher in fruits of tomato planted at 4 inches. Also, vitamin A (0.65 mg/100g), Vitamin C (23.80 mg/100g), potassium (17.93%), iron (5.80%) and magnesium (1.15%) were higher in tomato fruits produced by seeds planted at 4 inches followed by 6. Similar observation was noticed in phytochemical compositions. Four to six inches improved vegetative performance, nutritional and phytochemical compositions of tomatoes fruits, therefore cultivation of tomato between 4 and 6 inches is recommended
