This article presents the results of the researches in 2018-2019. Melon is distinguished by its relative origin, as well as the only agricultural crop created by the whole person. Now intensive work of breeders who sought to receive melons containing a large amount of sugar is begun. Its fruits contain fiber, pectins, organic acids, amino acids (lysine, valine, betaine, betaine, etc.), vitamins BB, vitamins C, folic and Pantothenic acids, potassium, iron, manganese, iodine, sulfur, cobalt, copper, zinc and other important elements of the periodic table. Melon-a complex culture in terms of agricultural technology. Most often it is a time-consuming and inefficient process. Before sowing, the land requires careful preparation, it is necessary to preserve the crop rotation. The timing of felling, irrigation, timing of fertilizer application, soil loosening must be carried out in accordance with the stages of the growing season of the melon, otherwise the yield is reduced and the final product is a melon does not reimburse the expenses for its cultivation. Herbicides were used to increase yields. Their influence on melon productivity is an actual problem of this scientific article.
