Growth Analysis, Yield and Canopy Structure in Maize-mungbean Intercropping

抄録

A field experiment was conducted on maize-mungbean intercropping to find out suitable mungbean variety (Kanti and BARI-mung-5) and its sowing systems in intercropping and to analyze the yield improvement from the viewpoint of growth process with the consideration of canopy structure and light interception. Maize yield did not differ significantly due to intercropping. On the mungbean monoculture BARI-mung-5 yield was higher than Kanti but on the intercropping BARI-mung-5 yield was reduced more than Kanti. The yield reduction of BARI-mung-5 was 73% and that of Kanti was 35-44%. The reason why Kanti has the tolerant co shading condition might come from smaller k value and higher NAR on later growth stage. There was no significant difference between the yield of 1 row and 2 rows sowing systems of munghean in intercrop treatments for both of the mungbean variety. Land equivalent ratio (LER) of plots intercropped with both varieties increased due to intercropping. The highest LER (1.58) was observed in intercropped with Kanti.
