Effect of Spraying Humic acid and Iron on Growth and Yield Characteristics of Potato, Solanum tuberosum L.

Abstract

Abstract: An experiment was carried out at University of Anbar to study the effect of spraying humic acid and iron compound on growth and productivity of tato on Altzona cultar class Eile spring 2016 The experiment involved spray of humic acid and iron alone and combination with the recce dosages of hertizers to sol (N 240, p 120, k 400 kg ha). The matteding coefficients generally exceeded the fertilizer recommendation and the control tras The recommendation of ground terilizer humic acid spraying spraying iron compound was resulted in significant increase in plant height, dry weight of the plant the average weight of the tuber and the yield per plant. The same treatment was also superior to the markant violet, marketable yield, local yield, dry maner percentage and the growth of subers.
