Field experiment was carried out at farm, EL-Gemmeiza Agricultural
Research Station during the two winter seasons of 2001-2002 and 2002-2003, to
study the effect of foliar spray of vit. C, is 100, 200 and 300ppm, Boric acid (500
ppm), vit., 8i (150ppm) and micronized sulphur (750g./fed.) on growth, yield and its
components and chemical composition on pea plants.
Results indicated that foliar spray with vit C (200ppm) increased no. of
leavesiplant followed by vit. 81 and 5 compared with control. While all treatments had
no significance on plant height in relation to both seasons. Moreover, height of the 15‘
fruiting node, plant yield, total yieldlfad., shell out %, no. of pods} plant and no. of
seedslpod were significantly increased by using vit C (200ppm) and vit. Bi (tSOppm)
in both seasons. Also, foliar spray with vit. Bi increased length and weight of pod,
weight of green seedslpod, and pod diameter in both seasons.
Foliar spray with sulphur (750glfed) and vit C (200ppm) caused a significant
increase in chl. a, b, a+b and carotein in leaves and crude protein in seeds in both
seasons. While all treatments had no significant differences in T88 and carbohydrates
in both seasons.
Positive significant correlation were found between no—of leaves with most
characters and among total yield ifed. and wt. of 100 seed, wt. of seedsi'pod, length
and wt. of pod, no of seeds! pod, protein, TSS chlorophyll and carotein.
Negative significant correlation were found between height of plant and height
of 1“ fruiting node, as betvveen no, of leaves iplant and height of 1St fruiting node.
Among no. of podsiplant and height of 1" fruiting node, also between total yield [Fed
and height of 1“ fruiting node. the correlations were significantly negative.
