Abstract:
In Romania, more than half of hail storm are in the period from May
to July. They are responsible for small losses of productions they occur in the
early stages of vegetation. Significant losses occur when hail storm occur
during flowering-silking period. James V. Vorst appreciates that monetary
losses caused by hail storm reach $ 52 million annually in the USA. Starting
from this consideration, but also in terms of attracting attention on providing
corn crops, in the spring of 2015 we established a two-way experience, in
Lovrin, Timisoara. The first experimental factor, corn cultivar has been
represented by 18 maize hybrids of FAO 350-550 maturity groups. The second
factor was the degree of defoliation on plants corn produced artificially in
various stages of vegetation. Results indicate losses of up to 5% when maize has
six leaves, 1-10% when corn has 10 leaves, of 9-62% during flowering-silking
and 6-41% when milk line was distinguishable.
