Abstract

This study was carried out at EI-Baramoon Horticultural Research Farm during
summer seasons of 2000 and 2001 to study the effect of some intercropping systems
(snap bean intercropped with pepper) and different nitrogen levels on certain growth
characters. Split-plot design with three replications was used. The main plots were
assigned for intercropping systems. while. the sub-plots were devoted to nitrogen
levels. The obtained results revealed that the most effective intercropping systems
were ISz (planting pepper on one side of the ridge and snap bean on the other side).
and IS3 (planting pepper on one side of the ridge and snap bean on the two sides of
the ridge without leaving one row for hoeing). Both systems of cultivation caused an
increase in plant height. number of branches, stem diameter and plant dry weight of
the two tested crops. Whereas. the highest plant height was recorded with IS, system
of the two tested crops.
With respect to the effect of nitrogen level applied. plant height. number of
branches, stem diameter and plant dry weight in both crops were increased as the
nitrogen level was raised up to 100 kg N/fed.
Plants of both crops studied grown under the combination between IS3 and IS₄
intercropping systems and received the zero level of
