Technological Investigations for Improvement of Grapevine Propagation Material Production in Bulgaria. Part II. Testing of Agritechnical Practices in Vine Nursery

The study was carried out at the Institute of Viticulture and Enology, Pleven for improvement the technology for the production of grafted rooted vines. The subject of the study included the agritechnical practices: irrigation and irrigation regime in vine nursery, application of herbicides for weed control and fertilizing with organic fertilizers was the subject of the study. In the comparative tested irrigation practices and irrigation regime in the nursery the results were in favour of the drip irrigation. The action of the herbicides Lumax 538 SC (375g/l s-metolachlor + 125 g/l terbuthylazine + 337.5 g / l mesotrione), Stomp 33 EC (330 g/l pendimethalin), Goal 2E (240 g / l oxyfluorfen) and Dual Gold 960 EC (960 g/l s-metolachlor) was studied. The organic fertilizers Humustim, Aagrohumustim, and Biohumus were tested for fertilization optimization. Fertilization with organic fertilizers had a positive effect on the growth processes in terms of the elements of growth and yield of grafted rooted vines
