This study was conducted during 2015–2017
seasons in the Agricultural Research Station, King Abdulaziz
University at Hada Al-Sham region, Saudi Arabia.
The aim was to investigate the effects of planting Al-
Hassawi clover between sugar beet rows in two intercropping
systems: 1 sugar beet row: 2 clover rows (1:2)
and 1 sugar beet row: 3 clover rows (1:3) besides sugar
beet monocrop and Al-Hassawi clover monocrop. Also,
number of harvested cuts from clover during the sugar beet
growing season (1, 2 and 3 cuts) on sugar beet yield,
sucrose yield, clover yield, leaf area index and land
equivalent ratio (LER) were investigated. No significant
differences were found between sugar beet fresh root or
sucrose yield/ha under the intercropping systems 1:2, 1:3 or
sugar beet sole crop with one or two cuts from clover.
Fresh forage yield/ha from clover significantly increased as
number of cuts increased using the two intercropping
systems. The highest clover forage yield/ha was produced
from the clover sole with three cuts. The highest LER was
produced under the 1:3 intercropping system with two cuts
or one cut of clover.
