Abstract EN

This research was carried out during the agricultural season 2021/2022 on a private farm in Wadi Souf El-Gin in Bani Walid, to study the effect of using compound fertilization (NPK) on the barley crop, and a local barley cultivar (Mubashir 4) was grown and fertilized with nitrogen fertilizer (urea 46%) At a rate of (100 kg/ha) when planting, then NPK fertilization was used at a rate of 200 kg/ha, and 300 kg/ha, sprayed on plants, in addition to the comparison group that was not fertilized, but was sprayed with water only.

The results of the statistical analysis showed that the treatment that was fertilized with 300 kg/ha NPK was superior to the rest of the treatments for all the studied characteristics, namely : (plant length (cm) - number of spikes per unit area (1m2) - number of grains in a spike - weight of 1000 grains (gm) - Green crop (tons, hectares) - Total grain yield (tons / hectares).
