Abstract

An assessment of the effect of mineral fertilizers on the accumulation of total phosphorus in the above-ground mass of oat plants on irrigated gray-brown soils of Azerbaijan was carried out. The studies were carried out in 2021. As a result of the work, it was found that, depending on the number of irrigations and the norms of mineral fertilizers on irrigated gray-brown soils of the western region, the yield of the aerial part varied. Various fertilization methods and rates tested. High total phosphorus was observed with double vegetative irrigation with N90P90K60 and triple irrigation with N120P120K90.
