Effect of Levels of Nitrogen Fertilizers and Intra Row Spacing on Growth Performance of Potato (Solanum Tuberosum) at Wolaita, Southwestern Ethiopia

Abstract

A field experiment was conducted at the experimental site of Wolaita sodo Universit Colleg of Agriculture  during 2017 cropping season .the objective of this study was to examine effects of level of nitrogen and intra row spacing on growth of potato. The experiment was conducted on a  randomized complete block design with three replications. The result of the experiment revealed significant difference among treatments with regard main stem number, plant height, leaf area, days 50% flowering, shoot fresh weight, total dry weight at(p<0.05). While the combined effect of Nitrogen fertilizer and spacing have no significant among treatments at (p<0.05). maximum  growth of potato were observed for all treatments at  the application  rate of 138kg nitrogen per hectare and50cm intra row spacing except main stem number (10.22)  which is at 30 cm, However the results of the experiment did not include yield components. Thus, a similar research should be conducted so as to assure the results of this experiment and to include yield components.
