Feasibility Of Using Super Absorbent Polymer And Nitrogen On The Yield, Biological Traits, And Nitrogen Percentage In Fields Pumpkin Seeds

This study performed to investigate the effect of nitrogen and moisture superabsorbent on yield, yield components, seed nitrogen and some biological traits in field pumpkin during two crop years in Kermanshah, Iran. The experiment was carried out as a split-plot based on randomized complete block design with three replications. The main plot factor were the application of moisture superabsorbent  in various levels at 0 (control), 40, 80, 160 kg ha-1 ,respectively; and nitrogen fertilization at the levels of 0, 50, 100 and 150 kg ha-1was considered as sub-factor. Results illustrated that treatments significantly affected all traits except for fruit number. In most traits, there was an increasing trend when nitrogen levels increased, although N2 levels of 100 and 150 kg ha-1 were not significantly different.. In addition, increasing the moisture superabsorbent enhanced the mentioned traits
