Leguminous crops, whose species characteristics and agronomic values allow their incorporation into sand farming, are of great importance for the environmentally friendly utilization of the acidic sandy soils of Nyírség. Among the legume cultivars that can be grown on acidic sandy soils, the hairy vetch is of outstanding importance, which is also been grown as green manure, green fodder, and seed, in Hungary, for more than a hundred years. Our observation aimed to examine, in a field micro-parcel experiment, at different sowing times, in six replicates, at three different recording periods, the plant height, the root length, the number of the Rhizobium root-nodules formed on the main and lateral roots, the number of seeds, the weight of the seeds, and the thousand kernel weight of the hairy vetch. From our experimental results, we found that the average height of the plants before the onset of winter, at the sowing time in late September, was between 11 and 18 cm, while the root length ranged from 16 to 26 cm. In the same phenophase (before winter) and sowing time, the highest number of Rhizobium nodules was measured on the main root (9.4–11.5), while the most efficient nodule formation on the lateral roots was in the budding period (13.7–27.6), also in the sowing time of September 20. In the studied years, the data on the number of pods per plant of hairy vetch showed an increasing trend with sowing time (5.6–12.2 pc/plant). The same increasing trend was observed for the number of seeds per plant (13.9–34.6 pc/plant). The highest seed weight (0.57–0.79 g) was obtained at the last sowing date. The results presented above also confirm that the cultivation of hairy vetch should become more and more important for sustainable land use. [ABSTRACT FROM AUTHOR] |
