In southern Kyrgyzstan, the growth and development of early potatoes has been studied, depending on nutrition background and the methods of growth stimulant Bereke GN, aiming to improve the yield and quality of potatoes. There were no scientific studies on growth stimulants impacts on potatoes, the productivity of early potatoes in southern Kyrgyzstan conducted. Field experiments were carried out on the experimental site of the Osh Technological University in the Kyrgyz Republic Osh region Aravan district Mangyt village in 2016-2018. In case of increasing the nutrition background, in terms of experiments on methods of using the growth stimulant Bereke GN in the phases of development of early potato plants, natural differences in variants were observed. Increased duration of interfacial periods is detected in increased power supply background. In all years of experiments in the variant complex application of growth stimulator, respectively increased nutrition backgrounds, green, thick and strong sprouts of 1.5-2.1mm length were formed. As well as complex use of growth stimulant contributed to accelerated emergence of sprouts. According to the results of our research, we have identified the dependence of plant preservation on harvesting from the application of fertilizers and the method of use of growth stimulant. Consequently, with the complex application of Bereke GN growth stimulant to early potato crops, there was an increase in the number of preserved plants for early potato harvesting by 0.7-1.6%, with seed tuber growth stimulant treatment by 0.3-0.6%, and with leaf spraying by 0.1-0.3%
