Two field experiments were conducted on sweet pepper
plants (cv. California Wonder) during the successive summer
seasons of 2000 and 2001, in the Agricultural Experimental
station, Alexandria University, at Abies. The objective of these
experiments was to determine the effects of nitrogen rates (60,
90 and 120 kg fed-1) and their application systems (three, four,
five and six split applications), on vegetative growth, fruit yield
and quality of sweet pepper. The obtained results indicated
that increasing N applied rate was accompanied with
significant increases in plant height, number of leaves, leaf area
and dry mass plant-1. Moreover, higher yield potential (yield
plant-1, number of fruits plant-1 and average fruit weight-1) and
better fruit quality (fruit dry matter, total soluble solids,
ascorbic acid and k content) seemed to be associated with the
application of 90 kg N fed-1.
