Description
The Sigma variety is recommended for growing as both a one-year crop from seeds and a two-year one from seed onions. The optimal sowing scheme for seeds is 20 by 5 cm, and for seed onions – 25 by 8 cm. Onion yield is high and reaches 5-7 kg per square meter, which corresponds to a marketable yield of 24-26 tons per hectare. Onion is well suited for long-term storage, which allows it to be used for a long time after harvesting.
One of the important advantages of the Sigma variety is its increased resistance to downy mildew, which reduces the risk of crop losses and reduces the need for frequent use of plant protection products. This makes this variety attractive for farmers striving to obtain a quality and stable onion crop.
