Effect of ionic strength and soil texture on phosphorus availability on wheat growth and production

Abstract

This study was conducted to find out the effect of ionic strength, addition of organic matter and soil texture on wheat plant. A field experiment was carried out during the agricultural season (2201-2022) in the College of Agriculture - University of Wasit using a completely randomized design (CRD). The study included 48 units resulting from a pot experiment. Wheat crop (Ibaa 99) and the use of three factors: ionic strength with three levels, denoted by F1, F2, and F3, two types of soil tissue, denoted by T1 and T2, and humic acid with two levels, denoted by M0 and M1. The study results showed that the increase in ionic strength led to a significant decrease in growth characteristics. And the yield of the wheat plant, as there was a decrease in the concentration of nitrogen, phosphorus and potassium in the leaves of the wheat plant, and the F1 treatment was superior to all treatments. And its content of nutrients, where the addition treatment excelled in all plant characteristics, and the addition of organic matter affected the dry weight of the vegetative total, the weight of a thousand grains, the biological yield, the grain yield, and the rate of plant height.
