| Abstract | ||
| Two field trials were conducted at Shandaweel Experimental station during 1994/95 and 1995/96 seasons to investigate the effect of intercropping onion with autumn-planted sugar cane under different plant densities of onion. The experimental design was randomized complete blocks with four replications. Each experiment included five treatments (sugar cane + three rows of onion, sugar cane + four rows of onion, sugar cane 4- five rows of onion and pure stand of sugar cane and onion). The important results could be summarized as follows: 1. Sugar cane yield was significantly affected by onion intercropping. The average yield of cane was reduced by about 9.9 and 8.4 compared with pure stand in first and second seasons, respectively. 2. Brix, sucrose and purity percentages of sugar cane juice showed no statistical significance between treatments. 3. Yield and yield components of onion were decreased by intercropping patterns as compared with onion alone. Yield of intercropped onion was increased by increasing of plants density of onion, whereas the diameter and weight of bulbs were decreased by increasing plant density of onion. 4. Intercropping onion with sugar cane increased the land usage by 4359%0. S. The aggressiveness values of intercropping components showed that the sugar cane crop was dominant while onion was dominate in the three different patterns. 6. The economic analysis clearly show that Intercropping five rows of onion produced the highest economic value and gross profit/fed compared with other treatments Finally, it could be recommended that intercropping five rows of onion with sugar cane was successful and profitable to production under conditions in upper Egypt. | ||
