PAPANIKOLAU, M., D. ATANASOVA, Sl.PANDELIEV and K. FARTSOV, 2009. Determination of the possibilities for biological production of grapes of “Mavrud” cultivar, grown in the region of Novi Izvor, municipality of Assenovgrad. Bulg. J. Agric. Sci., 15: 1-8
Experiments related to the possibilities for biological production of grapes of “Mavrud” cultivar in the region of Novi Izvor, Municipality of Assenovgrad, were carried out in the period 2006-2008.
It was determined that the terroir of the village of Novi Izvor is favourable for production of Mavrud cultivar. No heavy metals exceeding the allowable rates were found in the soil which shows that there is no industrial pollution of the air and the soil in the region. The condition of the grapes in both cultivation technologies was good. The percentage of rotted, moth-eaten and raisin-shaped berries was insignificant. There was not a large density of the grape cloth Lobesia botrana in the region and no damages were allowed due to the activity of the dispensers in the plantation. The grapes obtained under the biological technology have better condition for production of high-quality red wines compared with the conventional method of cultivation. The region of the village of Novi Izvor is suitable for biological production of grapes.
