corn (Zea mays L. var. Saccarata) in pure stand and intercropped
with mung bean (Vigna radiata L.), a field experiment was conducted
at Varamin region on summer 2006. Experiment was carried out in a split
plot design based on randomized complete blocks with 4 replications. Plant
density with 3 levels [Low (D1), Mean (D2) and High
(D3) respecting 6, 8 and 10 m-2 for sweet corn,
cultivar S.C.403 and 10, 20 and 30 m-2 for mung bean cultivar,
Partow] was arranged in main plots and 5 mixing ratios [(P1)
= 0/100, (P2) = 25/75, (P3) = 50/50, (P4)
= 75/25, (P5) = 100/0% for sweet corn/mung bean, respectively]
were arranged in subplots. Quantitative attributes such as plant height,
sucker numbers, LER, dry matter distribution in different plant organs
were measured in sweet corn economical maturity. Furthermore the yield
of cannable ear corn and yield components of sweet corn and mung bean
were investigated. Results showed that plant density has not any significant
effect on evaluated traits, while the effect of mixing ratio was significant
(p<0.01). Therefore, the mixing ratio of 75/25 (sweet corn/mung bean)
could be introduced as the superior mixing ratio; because of it`s maximum
rate of total sweet corn`s biomass, forage yield, yield and yield components
of ear corn in intercropping. Regarding to profitability indices of intercropping,
the mixing ratio 75/25 (sweet corn/mung bean) in low density (D1P2)
which showed the LER = 1.03 and 1.09 for total crop yield before ear harvesting
and total forage yield after ear harvest respectively, was better than
corn or mung bean monoculture.]]>Atri, A., Javanshir, A. Moghadam and M.R.M.
