GROWTH AND YIELD CAPACITY OF QUINOA (CHENOPODIUM QUINOA WILLD.) DEPENDING ON THE SOWING RATE IN THE CONDITIONS OF THE NORTH-EASTERN FOREST-STEPPE OF UKRAINE
The paper presents aimed research results of the density level effect on quinoa plant development, yield and yield components to ensure maximum efficiency of crop rowing under regional conditions. Research was carried out for 2020-2022 in area of North-Eastern Forest-Steppe of Ukraine with the quinoa variety of Quartet. Several sowing rates 0.8; 1.2; 1.6 and 2.0 million seed per ha) were studied. According to the results a continuous sowing technology with a sowing rate of 1.6 million similar seeds per ha is recommended. It provides a pre-harvest density of 1.37 million plant/ha and yield of 2.12 t/ha. Development and formation of the main crop of seeds ensures the main inflorescence of the central stem. The average yield index and weight of 1000 seeds were 27.9% and 2.82 g, respectively. For obtaining larger seeds (1000 seed weight > 3.0 g), it is advisable to reduce the sowing rate to 1.2 million seed/ha. Yield shortage at this sowing rate in some years can be up to 0.08 t/ha.
