PRODUCTION EFFECTS OF GREEN FERTILIZERS IN THE FORM OF FORECROPS IN VEGETABLE CULTIVATION

Romualda Jabłońska-Ceglarek, Robert Rosa

 

ABSTRACT



The studies examined production effects of green fertilizers (oats, field pea, spring vetch, and mixtures of these plants) ploughed over in spring in the cultivation of white cabbage, onion and red beet. In the first year after ploughing in, the forecrops of field pea and a mixture of field pea with vetch and a mixture of oat with field pea and with vetch were more productive green fertilizers in cabbage cultivation. On the other hand, in the cultivation of onion the forecrops of field pea and its mixtures with oat and vetch were the most productive fertilizers in the second year after ploughing in. In the third year after ploughing in, all green fertilizers were characterized by better consecutive yield-forming effect as compared to manure in the dose of 25 t·ha-1.

Key words: green fertilizers, manure, organic fertilization, cabbage, onion, red beet, yields.
