By results of researches it is established that application of mulching the soil with straw, sawdust and black polythene bag had a positive effect on growth, development, yield and biometric indicators of zucchini production. The use of black polyethylene film accelerates passage of phenological phases of growth and development of plants zucchini, then as the mulch materials of organic origin straw and sawdust delayed the onset of phenological phases of development. So, the shorter the period of germination – the beginning of the formation of the fetus was for the mulching of soil by polyethylene film black – 29 days, the duration of which is 8 days less in comparison with the variant without mulch. Longer fruiting period lasted for the mulching of soil by polyethylene film black – 92 days, and on the control of the 82 days, that is 10 days shorter. The results of the research revealed the influence of mulching materials on biometric indicators of zucchini plants. The maximum size of the stem in phase three true leaves was observed on plants by mulching the soil with polyethylene film black – 16,4 cm, and control – 13.8 cm, which is 2.6 cm less. The largest area in phase three true leaves had plants by mulching the soil with polyethylene film black – 55,8 cm 2 / plant, which is 8.1 cm2 / plant compared with a case where the mulching material was not used. The high yield production of zucchini provided the variant with application of mulch material of polyethylene film black – 52,1 t / ha. Application of straw and sawdust provided a yield increase of 2.6 and 4.2 t / ha, respectively. The greatest number of fruit received for the mulching of soil by polyethylene film black – 15,3 PCs. / plant, which is 1.4 PCs / plant more control. The highest fruit weight had the option to melirovanie of the soil with polyethylene film black – 313
