The effects of anti-hail net in protection of pear orchard after hailstorm occurrence
The use of anti-hail nets is considered as one of the most effective ways to protect orchards from hail. The effect of a transparent anti-hail net on the protection of fruits from hail, fruit quality, differentiation of flower buds, and growth of the trees after the hail incidence were evaluated at a pear orchard with cultivars 'Bartlett' and 'Red Bartlett'. The experiment was carried out in a net-covered and uncovered pear orchard located in the north-eastern part of Macedonia during 2014-2015. The experimental orchard was established in 2010, with a planting distance of 3.2×1.3 m. From each variant 60 trees in three repetitions were evaluated. After occurrence of the hail, results show high damages on the fruits on uncovered trees in both cultivars. Percentage of fallen fruits on uncovered trees ranged from 40% in 'Bartlett' to 48% in 'Red Bartlett'. Only 5 to 8% of the fruits were undamaged. Most of the fruits have three or more wounds per fruit. On the covered trees maximum protection from hail was obtained. Significant differences concerning growth of the trees and differentiation of flower buds were determined between covered and uncovered trees in both cultivars. Higher differentiation of floral buds, fruit set and productivity had trees covered by anti-hail net. In both cultivars an anti-hail protective net demonstrated its efficiency against hail, increased fruit quality and productivity in the same and in the next production year.
