THE FERTILIZING VALUE OF STRAW AND SUMMER CATCH CROPS FROM NON-PAPILIONACEOUS PLANTS IN RELATION TO VEGETABLE YIELDING
Jolanta Franczuk
ABSTRACT
The studies examined the fertilizing value of rye straw and green manure from non-papilionaceous plants in vegetable cultivation, in the soil and climatic conditions of central-eastern Poland against the background of the control, which was not organically fertilized, and farmyard manure. In the experimental conditions of the studies the size of the yields was related to the manner of using the intercrops. Higher yields of cabbage and red beets were obtained after ploughing in the whole intercrop biomass than after ploughing in the crop residues. The manner of using the catch crops did not cause any significant changes in onion yielding. The highest yields of vegetables were achieved after ploughing in the phacelia intercrop, which exceeded the effect of manure. Among the applied doses of rye straw, the best yield-forming effect during the studies was characteristic of straw in the dose of 4 t·ha-1.
Key words: green manure, non-papilionaceous plants, rye straw, yield, cabbage, onion, red beet.
