Testing of bio-organic fertilizer based on organic waste to improve the productivity of vineyards

The authors developed an environmentally safe technology for obtaining liquid organic fertilizer. includes compost by applying microflora containing actinomycetes and microscopic fungi, populating the with vermiculture Eisenia foetida biohumus. In 2018-2020 fertilizers obtained from waste were used on industrial plantings of technical variety Bastardo Magarachsky (planting scheme: 3 × 1.5 m, formation - double-shouldered cordon, rootstock Kober 5 BB, non-irrigated culture) as foliar dressing. Climatic zone place experiment: South Coast agroclimatic area, sub-area subtropical winter (annual rainfall 450-500 mm; hydrothermal coefficient moisture 0.5-0.6). Standard methods agronomic observations growth development grape plants in work. Consumption rate 2 l/100 liters water. number treatments six, terms application: shoots growth; before flowering; after berry beginning softening; sugar accumulation (a month harvesting). It was found that at background same potential productivity compared to control, yield increased 15,9%; mass fraction sugars juice 7,1%, mash output 14,7%; technological stock coloring phenolic substances 7,6%.
