Influence of Nitrogen and Potassium on Yield Contributing Bulb Traits of Onion
S. Dilruba , M.M.Alam , M.A. Rahman and M.F. Hasan

Abstract:
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.
