RGT SAKUSA soybean is a new variety in the mid-medium early maturity group 00, designed to unlock the true potential of the field through its balanced agronomic traits. The plant features compact size and good branching, contributing to high resistance to lodging and pod cracking. The vegetative period is 115-120 days, and the sum of effective temperatures (CHU) is 2600, making the variety well-adapted to various climatic conditions. Growth type — semi-determinate, plant height below average, and the height of the lower pod attachment is within 11-12 cm. Flower color is purple, pubescence is brown, and seed hilum is dark brown.
Thousand-seed mass varies from 200 to 220 grams, protein content reaches 41-43%, and oil content — 20-21%. High protein content and balanced indicators ensure high yield and product quality. The variety exhibits high resistance to lodging and pod cracking, rated at 9 points on a 10-point scale. Disease tolerance, particularly to sclerotinia, is high, rated 7-9 points, contributing to stable yield.
Recommended seeding rate is 550,000 to 650,000 seeds per hectare, equivalent to 110-125 kg/ha. It is advisable to inoculate seeds with nitrogen-fixing bacteria before planting to enhance plant nitrogen nutrition. The variety shows sensitivity to herbicides: metribuzin — high (9 points), pendimethalin — medium (4 points), metobromuron — low (1 point). All these characteristics make RGT SAKUSA a reliable and productive choice for cultivation under various agroclimatic conditions.
