Abstract: The present investigation was undertaken during the Kharif season of 1993 at Mahatma Phule Krishi Vidyapeeth/ Rahuri, with a view to work out optimum plant spacing and nitrogen level of newly evolved tomato cv. Bhagyashree. The experiment was laid out in Split Plot Design with 12 treatment combinations/ comprising four spacings (90 x 40, 90 x30, 75 x 40 and 75 x 30 cm2 ) and three nitrogen levels (150, 200 and 250 kg/ha). In closer spacing, number of days to flowering was reduced. The weight of fruit and number of main branches per plant were increased at wider spacing. The yield attributes such as number of marketable fruits per plant and total and marketable yield per plant increased at wider spacing. Total and marketable yield/ha was increased at closer spacing. The fruit quality parameters such as pericarp thickness, seed content, juice (%), and TSS (%) were increased at wider spacing while the acidity (%) and ascorbic acid content increased at closer spacing. The incidence of spotted' wilt virus was minimum at closer spacing. The growth contributing characters such as days to flowering/ height/ volume and number of branches per plant were influenced by different levels of nitrogen. Growth contributing characters and the fruit characters like size and weight of fruits were highest at 250 kg N/ha. Number of marketable fruits per plant and total and marketable yield per plant as well as per hectare increased significantly with increasing levels of nitrogen/ recording the highest values at 250 kg N/ha. The fruit quality parameters such as pericarp thickness/ seed content/ TSS (%)/ juice {%)/ ascorbic acid content/ acidity (%) and shelf life of fruits increased with increasing levels of nitrogen. Interaction effects of spacings and nitrogen levels were observed on yield attributing characters and seed content. The highest total and marketable fruit yield per hectare was recorded at the closest spacing of 75 x 30 cm and 250 kg N/ha which was at par with 75 x 30 cm spacing and 200 kg N/ha. The maximum number of marketable fruits per plant was recorded at the wider spacing of 90 x p 40 cm and 250 kg N/ha. The minimum seed content per kg of fruits was obtained at the closest spacing of 75 x 30 cm2 and 150 kg N/ha. The results obtained in the present investigation indicated that for tomato cv. Bhagyashree the spacing 75 x 2 30 cm and 200 kg N/ha was the best choice to obtain higher yields with good quality fruits.
