Study the wheat growth using plant waste, irrigation water quality and levels potassium

Abstract

      The field experiment was carried out during the agricultural season (2021-2022) at the College of Agriculture - University of Wasit. Wheat seeds, variety Ibaa 99, were planted using a completely randomized design (CRD), with the aim of testing different levels of salinity in irrigation water, alternating with fresh water, and their effect on the growth and production of wheat plants. The study showed the following results: The unburned soil gave the highest values in some of the studied characteristics: plant height, grain yield, spike length, biological yield, number of branches, number of ears, and content of elements of K, P, and N. They occurred in response to potassium fertilization, and the best level was the second level, K 2250 kg, as This concentration gave the highest values for the studied traits: plant height, grain yield, spike length, biological yield, number of branches, and number of ears. The effect of irrigation with salt water was clear in all the studied characteristics, as the first level gave 1.2 dSiemens. M-1 is the highest value for all studied traits. On the other hand, the second level, 4 dS.m-1, gave the lowest values.
