Determination of Nitrogenous Fertilizer Needs of Wheat in Kop Region

EasyChair Preprint no. 6804

Abstract

This study was carried out in order to determine the amount of NO₃-N in the soil of bread wheat, the calibration of the nitrogen applications in increasing doses in wet and dry conditions, the calibration according to the increases in the NO₃-N yield in the soil, the application of the NO₃-N amount in the soils and the estimated fertilizer amounts. According to the randomized blocks trial design, increasing doses of N in 28 locations containing different soil nitrate nitrogen (NO₃-N) in dry conditions (0, 3, 6, 9, 12 kg N da^-1) and in aqueous conditions (0, 2, 4, 6, 12 and 24 kg N da^-1) were applied in the form of urea (46% N). As a result of the research, statistically significant relationships were determined between the NO₃-N content of the experimental site soils and the product increase of wheat. Considering these relationships, the Mitscherlich-Bray equation for bread wheat plant grown on soils in dry conditions log (413-y) = log 143-b₁*0.184-0.170*x 8 kg or more of NO₃-N in soils and log in irrigated conditions. (624-y) = log 143-b₁*0.377-0.068*x It has been determined to provide increases in product if it is 18 kg or more.
