The field experiments were carried out during the two successive winter seasons of 2013/2014 and
2014/2015 in a Private Farm at Abo-Hammad District, Sharkia Governorate, to study the effect of
plant densities on plant growth, chemical constituents of some pea cultivars. The maximum values of
dry weight of roots, shoots and total dry weight / plant, chlorophyll a, b and total chlorophyll as well
as carotenoides in leaf tissues, number of pods/ plant, average pod weight, yield / plant and total yield/
fad., were recorded in case of cv. Lincoln while, cv. Alaska recorded the highest values of N, P, K
and total carbohydrate in shoot. Planting pea plants on one side of the ridge gave the highest values of
dry weight of roots, shoots and total dry weight/ plant, chlorophyll a, b, total chlorophyll and
carotenoides in leaf tissues, N, P, K and total carbohydrate in shoots, number of pods/ plant, average
pod weight and yield /plant. Whereas, planting on three or four sides of the ridge increased total yield/
faddan. Planting cv Lincoln on one side of the ridge gave the highest values of dry weight of roots,
shoots and total dry weight/ plant, chlorophyll a, b, total chlorophyll and carotenoides in leaf tissues,
number of pods/ plant, average pod weight and yield/ plant. Whereas, planting Alaska cv. on one side
of the ridge increased N, P, K and total carbohydrate in shoots. Planting Lincoln cv. on three or four
sides of the ridge and planting Master B cv. on four sides of the ridge increased significantly the total
yield/ faddan.
