Determining the Effects of Nitrogen Fertilizations with Irrigation on Yield, Yield Components and Nodulation in Bean (Phaseolus vulgaris L.)

The effects of nitrogen fertilisers applied by irrigation on bean yield, yield components, and nodulation were investigated in this study. Four distinct nitrogen fertiliser treatment times were made in a randomised full block design with three replications as 12 plots. I. fertiliser application, all nitrogen (60 kg/ha) was applied at sowing time, II. fertiliser application, nitrogen was divided into two and applied at sowing time, during first irrigation (30 kg/ha N), III. fertiliser application, nitrogen was divided into three and applied at sowing time, during first irrigation and second irrigation (20 kg/ha N), and IV. fertiliser application, nitrogen was divided into four and applied at sowing time, during first irrigation and second irrigation (20 kg/ha N). Flowering period (days), initial pod height (cm), biological yield (g/m2), 100 grain weight (g), and grain protein content (percent) all responded to nitrogen in a statistically meaningful way, according to studies. IV. Fertilizer application enhanced bean biological yield (501.90 g/m2) and grain protein content (32.60%) considerably. II. nitrogen fertiliser treatment with the maximum nodosity number of 70.90/plant divided into two However, statistically, there were no significant differences. Phaseolus vulgaris L. has a low BNF (Biological Nitrogen Fixation) capability. It’s critical to identify and apply nitrogen correctly to bean cultivation in irrigated circumstances. Based on our investigation, some significant outcomes were produced, however more extensive research results are required for certainty.
