An investigation was carried out during rabi season 2016-17 at College orchard, Department of Horticulture, Agricultural College and Research Institute, Madurai to study the effect of spacing and nitrogen levels on growth, yield and quality of Cherry Tomato (Lycopersicon esculentum var. cerasiforme. The crop were laid out in Factorial Randomized Block Design with three replications and sixteen treatment combination. Four levels of nitrogen viz.,75, 100, 125 and 0 kg/ha of recommended dose as urea, Four levels of spacing viz., 90x40cm, 100x40cm, 110x40cm and 120x40cm with Phosphorus and Potassium each@50kg/ha as basal were tried in all possible combinations. The study revealed that the effect of spacing and nitrogen had significant effect on growth, yield and yield attributing characters. All the growth, yield and quality characters were the highest at 100 kgN/ha, 50 kg phosphorus and potassium. The spacing of100x40 cm recorded the highest plant height, number of primary branches, number of secondary branches and number of leaves, leaf area, leaf area index, total chlorophyll, dry matter production, crop growth rate and relative growth rate, number of fruits, fruit weight, fruit yield per plant, yield per plot and estimated yield and quality in cherry tomato. The present investigation showed that the application of 100 kgN/ha and spacing of 100x40 cm increased the morphological, physiological, yield and quality parameters.
