Study on Productivity of some Legume Crops in Pure Cultivation and Mixtures



In the conditions of pot trial the productivity of birdsfoot trefoil (Lotus corniculatus L.) cv. ‘Targovishte’ 1”; sainfoin (Onobrychis Adans.) breeding N26, white clover (Š¢rifolium repens L.) cv. ‘Milka’, and subclover (Trifolim subterraneum ssp. brachycalicinum) cv. ‘Clear’, in pure cultivation and in mixtures was studied. The treatments were as follows: 1. birdsfoot trefoil 100%; 2. sainfoin 100%; 3. white clover 100%; 4. subclover 100%; 5. cocksfoot 100%; 6. birdsfoot trefoil+cocksfoot; 7. sainfoin+cocksfoot 8. white clover+cocksfoot; 9. subclover+cocksfoot; 10. birdsfoot trefoil+ subclover; 11. sainfoin+subclover; 12. white clover+subclover. The ratio between components in the mixtures was 50:50. Cocksfoot (Dactylis glomerata L.) cv. ‘Dabrava’ as a grass component was used. It was found, that aboveground dry matter yield of white clover, birdsfoot trefoil, sainfoin and subclover in mixture with cocksfoot was higher as compared to these in pure cultivation. Subclover in mixture with birdsfoot trefoil increased aboveground dry matter yield, but in mixture with sainfoin and white clover did not contribute to increase of their productivity.
