Abstract

A field experiment was carried out in the soil of alluvial tissues fusion in summer season of 2013 in Abu Flees area which is a part of Al Khalidiya district which lies on longitude 43Oand latitude 33O to investigate the effect of four levels of potassium (0,40,80&120 kgK.ha-1 ) and four concentrations of Zinc ( 0,30,60&90 mgZn.L-1), which were added as a leave nutrition, in the growth and yield of Soybean crop of GS lll class. In experiment used the order of the split-plot according to the randomized complete block design (RCBD) and four replications. Potassium levels occupied the main split-plots, while Zinc concentrations occupied the secondary split-plots. The results of the experiment are summarized as follows:
The 90mgZn.L-1 concentration revealed the highest average of plant height, the rate of Zinc and Potassium in the leaves, and the seeds crop product. This concentration did not differ significantly in most of its traits with the concentration 60 mgZn.L-1 which was prominent and high significantly in the leave area, dry plant weight, root length. The level 120 kgK.ha-1 indicated the highest average in the plant height, leave area, the weight of dray plant, the roots length, the rate of Zinc and Potassium in the leaves, and the product of plant seeds. This was not significantly different in most traits under study with the level 80 kgK.ha-1. The interaction between Potassium and Zinc significantly affects all the studied traits. The interaction between the level of 120 kgK.ha-1 and the 90mgZn.L-1 concentration revealed the highest rate in leaves area (249.8 dcm2), the length of the main root (34.65cm), seeds crop (96.13g.pl-1). Finally, it is concluded that there is a significant response in the studied traits when adding Potassium to the soil and at the nutrition of leaves with Zinc.
