Response of Wheat (Triticum aestivum L.) to Organic Manure and Manganese Levels Applications in Two Different Soil Orders

Abstract

This study conducted to investigate the effect of organic manure and different levels of Mn on the wheat growth and yield at two different soil orders (Mollisols and Vertisol) in Sulaimani-Kurdistan Region of Iraq. Pot experiments was conducted during (November 12th, 2021 to May 10th, 2022), two rate of organic manure (0 and 2) % of (sheep manure) and five different levels of Mn (0,5,10,15 and 20) mg Kg-1 as MnSO4.H2O were used to the soil. The experiment was carried out using a factorial complete randomized design (CRD) in Triplicate. Growth characters, reproductive, and total dry matter were evaluated. The result showed that application organic manure and Mn were affected on the growth characters of wheat, except plant height (cm) and flag leaf area (cm2). While all reproductive characters were significantly affected with the fertilizer application. Total dry matter increased with application of organic manure and Mn levels in both soil orders. In Vertisol, total dry matter superior (40.813 %) from the most other application levels.
