Summary
Four intercropping patterns and one mono cropping as control were tested in an organic production of green onions (Allium fistulosum L). The four patterns were as follows: (1) one row of marigold (Tagetes erecta L) for every 2 rows of green onion, (2) one row of marigold for every 4 rows of green onion, (3) one row of tomato (Lycopersicon esculentum Mill.) for every 4 rows of green onion, and (4) one row of tomato for every 6 rows of green onion. The test was repeated for two crop seasons. Intercropping 1 row of marigold with every 2 rows of green onions produced the highest per cluster weight as well as the highest per 100 m2 mean yield of green onions. Other patterns of intercropping also had a strong tendency to increase per cluster weight and mean yield over monocropping. The land equivalent ratio was higher than 1 in all four intercropping patterns; thus the economic return of intercropping was higher than that of mono cropping green onions. In the 2008 observation, intercropping delayed the infection and reduced the severity of green onion rust disease. Intercropping green onions with marigold was particularly effective to mitigate this disease.
