EVALUAREA PRODUCTIVITĂȚII ȘI A PARAMETRILOR AGROBIOLOGICI LA GENOTIPURILE DE SOIA ÎN FUNCȚIE DE EPOCA DE SEMĂNAT

Abstract

This study evaluated the influence of sowing time on the productivity and agro-biological parameters of soybean genotypes under the specific climatic conditions of the central region of the Republic of Moldova. Two sowing dates were compared for six genotypes obtained through gamma ray-induced mutagenesis and conventional hybridization. Higher-than-usual temperatures during this period favored uniform emergence of 100% of the plants. The genotypes obtained by mutagenesis showed more stable productivity and superior adaptability to variations in sowing time, while those derived from hybridization exhibited high yields at early sowing but significant decreases at delayed sowing. These results emphasize the importance of selecting the optimal sowing time according to genotype type to maximize production and agro-biological performance.
