This study was conducted during the winters of 2021 / 2022 in the research farm of the Higher Institute for Training Teachers in N'Djamena City, Chad. It is regarded as the first field experiment for the wheat crop ever implemented in N'Djamena. The purpose of the experiment was to compare the effects of chemical and organic fertilizers on wheat crop productivity. We used soft wheat, Triticum aestivum (variety, Somps. 90), that was obtained from (SODELAC). Dry cow dung and NPK fertilizers were applied at recommended doses of 40 tons ha-1 and one tons ha-1, respectively. These fertilizers were applied separately three weeks before planting. In comparison to the control, the addition of dry cow dung and NPK significantly increased the following: leaf surface area (27.19 and 24.21 cm2), weight of grains/m2 (349.66 and 264.44 g), dry weight of the crop (284.44, 277.33 g), and the total productivity were 3.50 and 2.64 tons ha-1, respectively. The outcomes also showed that there were no significant differences between the investigated treatments concerning leaves number, spike length, number of spikelets and grains per spike. Our study led to the conclusion that applying organic fertilizer (dry cow dung) with chemical fertilizer (NPK) gave the best result in the production of T. aestivum (variety, Somps. 90) so, we recommend using dry cow dung and NPK fertilizers to increase vegetative growth and obtain the highest wheat crop productivity in N'Djamena city.
