Abstract:
Boron fertilization is an
efficient technological work, especially
when boron is applied on organic
background. The obtained results pointed
out the role of boron in plant metabolism: it
stimulated the accumulation of some
biochemical components in leaves
(chlorophyll and carotene), intensified the
activity of some enzymes (catalase) and
improved fruit quality. In the variants
where boron compounds were applied,
greater chlorophyll content, 4.31-4.46 mg/g
fresh matter, was recorded, compared to
2.14 mg/g fresh matter in the unfertilized
variant and 4.00 mg/g fresh matter in the
variant where only manure was used. The
carotene content of leaves was of 0.73-0.79
mg/g fresh matter, compared to 0.49 mg/g
fresh matter in the unfertilized variant and
0.63 mg/g fresh matter in the variant where
only manure was used, in 2005. The
quantity of total DM from fruits has
increased from 9.35% in the unfertilized
variant to 10.20-10.35% in the variants
fertilized with manure + Folibor 5 l/ha - two
treatments. On the organic background of
30 t/ha manure, by the leaf application of
Folibor, yield increase was of 10.7 t/ha.
