INFLUENCE OF THE PLANT GROWTH REGULATOR KAMETHUR ON THE MORPHOLOGICAL FEATURES AND YIELD OF CHINESE COWPEA (VIGNA SINENSIS L.)

In field conditions, the effect of the synthetic plant growth regulator Kamethur, created on the basis of the potassium salt of 6-methyl-2-mercapto-4-hydroxypyrimidine, on the processes of growth and development, as well as the formation of productivity of Chinese cowpea (Vigna sinensis L.) during its introduction in the southern steppe zone of Ukraine, was studied for two years. It was found that under the conditions of pre-sowing treatment of seeds of Chinese cowpea plants with aqueous solutions of the plant growth regulator Kamethur, applied in concentrations of 10^-5M and 10^-6M, the morphometric indicators of plants and pods, as well as the qualitative indicators of seeds, increase compared to control plants not treated with the growth regulator. The obtained research results indicate the possibility of practical application of the synthetic plant growth regulator Kamethur for pre-sowing treatment of seeds of Chinese cowpea to improve growth and increase the yield of this crop during its introduction in the southern steppe zone of Ukraine.
