ABSTRACT

The effect of green fertilizers in the form of forecrops was studied on the yielding and growth of sugar maize ‘Landmark F₁’. The maize was cultivated directly after organic fertilization. The plants intended for green fertilizer were sown in the first 10 days of April, and they were ploughed over in the first 10 days of June. The yielding of sugar maize was related to the course of the weather conditions in particular years of the experiment. Its highest yields were obtained in 2002. Application of organic fertilization caused an increase of maize yields as compared to the cultivation without organic fertilization. It yielded the best after field pea, a mixture of vetch with field pea and after manure. The weather conditions in particular years of the studies had a significant effect on the height of sugar maize plants, the number of cobs on 1 plant, the length, diameter and mass of the cobs. The highest plants grew after manure, the mixture of vetch with field pea and after field pea. The greatest number of cobs on 1 plant was found in the cultivation of maize after field pea. The cobs collected from the maize cultivated on the ploughed after-crop residues were significantly longer than those collected from the maize grown after ploughing in the green fertilizers as the whole. The longest cobs were observed in the cultivation of maize after ploughing in the field pea. The biggest diameter of cobs was characteristic of the maize grown after ploughing in the green fertilizer from field pea. The greatest mass was found for the cobs collected from the maize cultivated after vetch. The biggest mean mass of grains themselves was characteristic of the cobs from the plants grown on the plots with the ploughed in green fertilizer from field pea.

Key words: organic fertilization, green fertilizers, forecrop, sugar maize, yield.
