Effect of Nitrogen Levels on Morphological and Yield Response of BARI Tomato-9

An experiment was conducted to study the growth and yield response of tomato. Experiments consisted of four nitrogen levels viz. Control: No nitrogen, N1: 100 kg/ha, N2: 150kg/ha and N3: 200 kg/ha using Randomized Complete Block Design with three replications. Tallest plant (91.4 cm) was found from N2. Maximum number of leaves (97.8/plant), number of branches (10.7/plant), number of flowers (6.4/cluster), number of fruits (5.1/cluster), number of clusters (15.3/plant), fruit diameter (15.6 cm), individual fruit weight (73.1 g), yield (22.2 kg/plot and 61.4 t/ha) and Total Soluble Solid (TSS) (5.5%) were found from N2 while minimum from N0. It was observed that yield, growth parameters and yield contributing attributes are positively correlated with nitrogen levels except control; 150 kg/ha nitrogen was found the best compared to other nitrogen level used in this experiment for growth and yield of BARI tomato - 9.
