Site requirements:
Jasia will meet the expectations of growers when cultivated on poor soils. It is tolerant to temporary drought. Jasia is beyond compare to other varieties due to its high yield potential, exceeding 50t/ha. Even though the starch content is not the highest, the starch yield per unit area is very high. Jasia has low demands to fertilization. It is worth to minimize the dose of long-acting forms of nitrogen to avoid late maturing.
