EFFECT OF AMMONIUM PHOSPHATE FERTILIZER ON ALFALFA (MEDICAGO SATIVA) PRODUCTIVITY IN UZBEKISTAN

The article provides results of scientific research on effect of ammonium phosphate fertilizer on productivity of alfalfa in the irrigated conditions of Uzbekistan. It is well known that the fertilization of alfalfa with ammonium phosphate is an important production factor to get high and stable yield in the country. It can be concluded that there is little known about alfalfa yield response to N rates and there is a need to further investigations on alfalfa yield response to N in the irrigated conditions of Uzbekistan.
