Two Field experiments were conducted at shandaweel Experimental station
during 2000/2001 and 2001/2002 seasons to evaluate the effect of intercropping
sugar beet with onion, chickpea and faba bean under different ridges width (60.80 and
120 cm.) on yield and yield components of sugar beet. The experimental design was
split plots with four replications.
The most Important results could be summarized as follow:
Yield of sugar beet was significantly reduced by intercropping, and when
Intercropping with faba bean was more reducing compared with pure stand in both
seasons. Yield and yield components of sugar beet grown on wide ridges were
higher than that grown on narrow ridges. Sugar beet grown pure stand on wide
ridges (120 cm.) had the highest values, while the lowest values were observed
when intercropping with faba bean on narrow ridges (60 cm.).
2· Chemical characters of sugar beet i.e. T. S, S, %, sucrose % and purity % were
aHeeted by ridges width and intercropped crops.
3· Onion pure stand or intercropped on ridges 120 em. gave higher values than
ridges 60 and 80 cm. width. Bulb yield t I fed. was significantly decreased by
intercropping in both seasons.
4· Chickpea seed yield I fed. was significantly decreased by intercropping in both
seasons compared with pure stand. The treatment of 120 em. ridge width gave
higher values of seed yield 1 fed. as solid or intercropped with sugar beet.
5· Yield of faba bean grown as solid on narrower ridges (60 cm.) were higher than it
grown on wider ridges (120 cm.). While intercropped faba bean grown on wider
ridges (120 em.) was higher than it grow on narrower ridges (60 cm.).
6· The highest value for L.E.R. was 1.55 when intercropping sugar beet with onion
under wide of ridge 60 cm followed by 1.52 under 120 cm while the lowest values
observed when intercropping sugar beet with faba bean were 1.13 , 1.08 under
wide of ridge 60 cm in the first and second seasons, respectively.
7· Intercropped chickpea with sugar beet in ridges 120 cm. increased gross and
benefit and profitability by L.E. 756, 482 and 10.2 % respectively than that of pure
stand sugar beet in wide ridges 120 em ..
