Option 1 of the experiment was controlled and fed with nitrogen fertilizers at the rate of 75 kg per 100 kg of P and 50 kg of K per hectare. In option 2, the norm adopted on the farm was taken and fed to the fund at the rate of 100 kg, in option 3 at the rate of 125 kg and in option 4 at the maximum rate of 150 kg of melons per hectare.

Irrigation of crops was also carried out in accordance with the recommendations. Irrigation was carried out at a rate of 65-70% relative to CHDNS
The experiment used 34% ammonium nitrate from nitrogen fertilizers, 19% superphosphate from phosphorus fertilizers and 50% potassium chloride salt from potassium fertilizers.
75% of phosphorus fertilizers and 100% of potassium fertilizers were applied during plowing. The remaining 25 percent of phosphorus fertilizer and 50 percent of nitrogen were applied before planting. The remaining 50% of the nitrogen fertilizer was applied to the furrows to a depth of 10-12 cm after the crops had produced three or four leaves.
In the experiment, the late melon variety ‘Qora po’choq” was planted on May 25. The melon was singled out when the leaves came out and at the time of the first mowing. After 25 days of germination, after two or three true leaves appeared, the crop was pruned for the first time, first watered and fed. The second hoeing took place 30 days after the first. During the growing season, row spacing was cultivated 4 times.
The winter melon crop is harvested on October 15, the period of technical ripening of the fruit, ie the period when it is possible to consume.


Results.
In recent years, advanced agro-technologies have been developed and introduced into agricultural production in order to grow rich and high-quality crops. The variety and variety of cultivated plants are being multiplied, new varieties are being planted every year, and seed and seed production is being organized.
We also tried to solve the above problems in our experiments. In particular, we managed to obtain data on the study of the influence of mineral fertilizers, including nitrogen fertilizers, on obtaining abundant and high-quality grain from late melons and gourds.
Growth of plants - this change of plant organs (height, number of lists, mass), and development - this change of plant quality, formation of generative organs, the process of ontogeny. this transition from one period to another.
Every agro-technical measure taken should be aimed at ultimately ensuring high yields. Yields, in turn, are formed in well-developed and vigorous plants.
Based on the goals and objectives of the experiment, the effect of the amount of nitrogen fertilizer applied on evening melon yield was determined. The data obtained are presented in Table 2 below.
