  The experiment was conducted to investigate the effect of different levels of nitrogen and potassium on yield contributing bulb traits of onion cv BARI Peaj-1. All the bulb traits in the experiment were influenced significantly by the individual treatment of different doses of nitrogen and potassium except dry matter content for nitrogen and showed a positive linear relationship. In the experiment, fresh weight of bulb, bulb dry weight, bulb diameter and yield per plot gave almost two times higher performance (35.29 g, 3.21g, 3.98 cm and 1.68 kg, respectively) by the treatment of 100 kg N ha-1 than that of no nitrogen application (18.93 g, 1.48 g, 2.02 cm and 0.95 kg , respectively). The performance of the doses of potassium (0 kg K2O ha-1 to 120 kg K2O ha-1) on bulb characters and yield of onion was less than that of nitrogen. There was no interraction between nitrogen and potassium in the influence of the expression of the characters. Among the combinations, the treatment 100 kg N with 120 kg K2O ha-1 was found to be the best from overall considerations.

  The study was conducted to analyze the responses of two tomato varieties, BARI tomato-4 and BARI tomato-6 to different environments. The environment used in the experiment were no mulch or control (E0), straw mulch (E1), black polythene mulch (E2), water hyacinth mulch (E3) and am-ada leaf mulch (E4). There were significant influences of different mulches on the growth and yield of tomato. The height of plant, number of leaves, number of main roots, length of roots, fresh and dry weight of roots, number of flower and fruit clusters, number of fruits per plant, weight of fruits and fruit yield per hectare were significantly higher under the environment provided by black polythene mulch. There were also variations in yield contributing characters between the varieties. BARI tomato-6 produced higher yield (55.16 t ha 1) than BARI tomato-4 (51.8 t ha 1). Among the variety-environment combinations the highest yield (61.18 t ha 1) was produced by BARI tomato-6 under the environment of black polythene mulch. This combination also gave the best economic return (BCR = 4.52).
