ABSTRACT

A scientific research work was conducted during 2018-2019 in the educational-experimental farm of the Tashkent State Agrarian University to study the effectiveness of plant growth stimulators on the productivity of tomatoes in the conditions of Tashkent region. The aim of the research was to study the physiological characteristics of tomato hybrids during the use of various plant growth promoters using the drip irrigation method. The task of the research was to study the effect of plant growth stimulators on tomato yields. Carrying out a comparative analysis of the obtained data about the yield, it can be concluded that the growth stimulators effect positively on the development and productivity of tomatoes. Over the 2 years (2018-2019), “Uzbekistan-178” hybrid was found to be the highest yielding, on average 76,6 t/ha. The highest productivity in the experiment (159,9 t/ha) was noted in “Vostok-36” hybrid using the preparation T-86. “Vostok-36” hybrid turned out to be the most productive as well -142,8 t/ha, respectively. In general, both stimulators are highly effective and can be recommended for practical use.
