Abstract
The trials were carried out during 1990 – 1992 (with cv.
Prelom), and during 1993 – 1995 (with cv.
Rousse 13), at the experimental protected cell of the IWS near Gen.
Toshevo.
The effect of the protective forest belts for the region of Dobroudja was studied on plots located parallel to the northern and southern forest belts at a distance of 7.5 m, 15 m, 30 m, 50 m, 75 m, 100 m, 125 m, 150 m, 175 m, 200 m, 225 m, and 250 m (cell center). Chemical, culinary and technological analyses were performed on representative seed samples.
It was found that two yield maximums and three yield minimums were formed in the protected cell.
The seed yield in the immediate vicinity to the northern and southern belts was, according to the control, as follows: 48.8 and 38.0 % in cv.
Prelom, and 52.2 and 27.4 % in cv.
Rousse 13. The maximum yields were produced in the zones 175 – 200 m from the northern belt, and 50 – 100 m from the southern one.
On the average the protected cell seed yield was higher than the control by 5.4% in Prelom, and by 5.6 % in Rousse 13. Cultivar difference concerning yield was not found.
The protective belts effected positively the seed quality.
An increase in the raw protein content of the seeds, as well as an improvement in the main technological indices – cooking time, seed coat and water absorbability – were found.
