| Abstract | The article presents the results of experimental studies that solve the scientific problem of studying the timing of sowing common beans to increase plant productivity and grain yield. The research was conducted during the years 2021–2023 on the research fields of the separate division of the National University of Bioresources and Nature Management of Ukraine "Agronomic Research Station" under the GDR "Innovative varietal technologies of growing beans in the conditions of the Right Bank Forest Steppe of Ukraine" (state registration number 0121U111195). Field experiments were established in accordance with existing methods in quadruplicate. The size of the sown plots is 50 m2, their accounting area is 25,2 m2. Varieties: Bukovinka, Hope and Pearl. Sowing dates: April 25 (I), May 5 (II), May 15 (III). The research results showed that the best conditions for the germination of bean seeds are created when sowing on May 5. The field similarity is the highest in the Nadiya variety – 95,2 %, the lowest in the Bukovinka and Perlyna varieties for sowing on May 15 – 91,8 % and 91,7 %, respectively. The duration of the growing season was the longest in the Bukovinka variety, 89,6 days, and the shortest in the Perlina variety – 74,7 days. The largest number of beans per plant was recorded during the early spring sowing period on April 25 in the Perlina variety – 26,1 pieces. Accordingly, the number of grains per plant was 167 pcs., the number of grains in a bean was 6.7 pcs. The highest grain yield was achieved by the Bukovinka variety – 3,03 t/ha, for bean sowing on May 15, the Nadiya variety – 3,01 t/ha for May 5 sowing, and the Perlyna variety – 2,88 t/ha for May 15 sowing. | ||
