Effect Levels of Zeolite and Organic Matter on the Available of NPK Elements and Some Chemical Characteristics of the Soil Planted With Sorghum Crop

Abstract

This study was conducted to find out the effects of zeolite mineral and organic matter at levels on the chemical properties of the soil and its effect on the grain yield of sorghum crop. A field experiment was conducted during the agricultural season 2020–2021 AD in Al-Muthanna Governorate at Al Bandar Agricultural Research Station of the College of Agriculture and implemented using the randomized complete block design RCBD the study included two axes:

• The first is the addition of zeolite mineral at levels (0, 1, 1.5, 2) % by volume
• The second is the use of levels of organic matter (0, 1, 1.5, 2) %. The ready NPK was calculated in the soil during the 50% flowering stage, and a set of measurements related to the soil were calculated.
