Özet

Field studies were conducted in Iraq, in 2021, to evaluate the effect of reducing irrigation water and reducing the amount of mineral fertilizer on soil salinity and some growth characteristics and yield of wheat. The treatments comprised 2 irrigation systems, i.e. surface and sprinkler irrigation, and 4 fertilizer application rates (200, 250, 350 and 450 kg/ha). Data were recorded on the number of spikes per square meter, number of spike grains, harvest index, weight of the grains and the weight of 1000 grains. Results showed that the best treatment combination that achieved the highest values for the studied traits was the application of 450 kg fertilizer/ha together with sprinkler irrigation.
