Abstract

In irrigated agriculture, increasing crop yields must go hand in hand with a continuous improvement of soil fertility. Today, the application of mineral fertilizers at different rates and the minimization of tillage are of great importance not only in our country but also in the irrigated agriculture of Central Asian countries. Nitrate nitrogen contained in high doses of nitrogen fertilizers applied without scientific justification is easily leached by irrigation water and pollutes the natural environment. On such lands, developing effective methods of minimizing tillage and applying nitrogen mineral fertilizers, as well as studying their agroecological aspects, is a pressing issue. The article discusses the methodology and results of studies conducted with a range of different nitrogen fertilizer rates.
