Amphor soybean variety is a medium-maturing, high-yielding new-generation variety with a vegetation period of 126 to 129 days. Plants are indeterminate, medium height, reaching 70-75 cm, with the lower pod set at about 15 cm. Flowers are purple, and the seed hilum is yellowish, which is a distinctive feature of this variety. Amphor is characterized by adaptability and is suited to various soil types and climatic conditions, allowing cultivation in different regions, including the Lower Volga (8) region, where it is registered in the State Register.
The variety is characterized by high yield potential, reaching up to 8.5 tons per hectare, and resistance to lodging, shattering, and sclerotinia. The thousand-seed weight ranges from 135 to 153 grams. Protein content in seeds is about 40.6%, and oil content is 20.5-23.1%, making Amphor attractive for producing protein- and oil-rich products. Soybeans also exhibit excellent resistance to cracking and diseases, contributing to a stable and high-quality harvest.
For optimal cultivation, traditional soil preparation methods typical of the growing region are recommended. The variety is not demanding regarding sowing methods, but early and mid-season sowing with row spacing of 15 to 35 cm is optimal. Recommended planting density varies from 450,000 to 650,000 seeds per hectare depending on moisture conditions and sowing dates. All these characteristics make the Amphor variety a universal and reliable choice for agricultural producers aiming for high-quality soybean yields.
