Maximizing productivity by intercropping some winter crops on suger beet [electronic resource].

Includes references.

Two field experiments were conducted at Mallawi Experimental Station (Middle Egypt) during 200212003 and 2003/2004 seasons to study the effect of intercropping sugar beet with onion, faba bean or wheat on yield and yield components of sugar beet . The experimental design was randomized complete block design with three replications. The important results could be summarized as follows: 1. Yield of sugar beet was significantly reduced by intercropping and the reduction was more evident wheat as compared with pure stand in both seasons Yield and yield components under bed system (120 cm) were higher than that grown on ridges (60 cm) . 2. Chemical characters of sugar beet i-e T.S.S %. sucrose % and sugar yield / fad were significantly reduced by intercropping and the reduction was in highest value when intercropped with wheat comparing with pure stand in both seasons. 3. Intercropping onion with sugar beet on bed system gave higher yield than on ridges. Bulb weight under bed system was heavier than under pure stand, However intercropped bulb yield /fad was reduced as compared to pure stand. 4. Faba bean and wheat yield were significantly decreased by intercropping comparing with pure stand. The yield of faba bean and wheat grown with sugar beet on bed system were higher than under ridges. 5. The highest values of LER and gross return were observed when sugar beet intercropping with onion on bed system . This study showed that grown sugar beet with onion on bed system gave the highest economic return for the farmers.
