The effect of rye straw fertilization at the rate of 5 t ha-1 (straw, straw + 1% N in proportion to straw weight) on vegetable yields in a 3-year rotation of cabbage, onion, and early potato were investigated. The fertilizing effect of straw was compared with the farmyard manure rate of 25 t ha-1 and cultivation without manuring.

By using straw fertilization it was possible to obtain high vegetable yields in light soil. The yield effect of straw in the first and second year after ploughing in was on the same level as that after the use of farmyard manure at the rate of 25 t ha-1. The productive effect of straw in the third year after ploughing in, was marked by a rise in the marketable potato yield in relation to the non-manured field, were 2-times lower on average than that using farmyard manure. The effect of straw fertilization was similar to that of straw with 1% N.
