Abstract
Two field experiments were carried out in 2000 and 2001 seasons at the Experimental Farm (Cockle Park farm) of the Faculty of Agriculture, Newcastle University, to investigate the effect of shade, drought, nutrients and shade + drought + nutrients on vegetative growth, yield of pea (c.v. Eiffel) and its quality, as well as photosynthetic activity. The results showed that nutrients treatment (formula-4) increased vegetative growth (plant length, number of reproductive nodes, both fresh and dry weight of stems, stipules, tendril, and pod of pea plant) and yield and its components (pod fresh weight, number of pods and number of seeds per plant. On the other hand, the lowest values of most studies characters were obtained by the drought treatment. Regarding the effect of studied treatments on photosynthetic activity, it may be concluded that nutrients treatment caused an increase on photosynthetic activity characters of pea bottom leaves (delta e, delta c, E, gs and A) at most of ages of leaves (71, 82, 93 and 100 days from planting), while the control treatment increased e ref, c ref, U and Ci. On the other hand, delta c, E, gs and A were at maximum values on top pea leaves with nutrients treatment in both ages of 93 and 100 days from planting.
