DETERMINATION THE EFFECT OF NITROUS FERTILIZERS ON INTENDED FOR SILO PROCESS OF MAIZE WHEN INTERCROPPING SOYBEAN WITH MEIZE HYBRIDS AS A REPEATED CROP

Relevance of the topic. In recent years, special attention has been paid to increasing the land fund and increasing its productivity in Uzbekistan. In recent years, 15-25 thousand/ha of new land has been developed and 40-50 thousand/ ha of land has been improved. But the size of the land is limited, and due to the lack of water, the possibility of adding additional areas to the agricultural cycle is also limited. Therefore, it is necessary to determine the methods of using the existing land fund. Serious attention is paid to the development of grain production in our country . In our republic, this wheat is not planted on large areas, in watery lands, this wheat is planted on 1,000,000 hectares of land. In order to grow a second crop using the lands planted with this grain , in several different directions scientific works are carried out . As repeated crops, crops such as maize, wheat, sorghum sudan grass, oats, and soybeans can be planted. In order to grow high -yield fodder, which is required for animal husbandry, sowing maize and soybean as a repeated crop is an important technological event. Maize is a high - yielding plant, which contains enough nutrients, but does not meet the requirements of protein and medicine. Soybean is a nodule - rich plant, and foods prepared from it contain a lot of nodules and a small number of units of food. That's it If both plants are planted together, it is possible to grow food that meets the quality requirements. The purpose of the scientific work is to determine the effect of nitrogen fertilizers on the yield of silage maize in the intercropping of maize and soybean hybrids as a repeated crop. The scientific novelty is that a hybrid of maize and soybeans can be planted in the fallowed fields to produce grain and silage crops. The effect of nitrogen fertilizer rate was studied and an alternative rate was determined. In this context, the growth, development, and characteristic formation conditions of the crops involved in this sowing were studied. The practical importance of the work - as a repeated crop, hybrids of maize and oats are planted with Uzbekistan - 2 varieties of soybeans. When the rate of fertilizers is N150P90K60, favorable conditions are created for the cultivation of high grain and silage crops and the efficiency of land use increases.
