| To determine the effect of intercropping of maize with potato on yield, yield components of two crops and land equivalent ratio (LER), a field experiment was conducted in Shahid Moghabeli Agricultural Research Center of Jiroft and Kahnooj, Iran, in 2010 and 2011 cropping seasons. The experiment was grown as early-planting in spring. The experimental treatments included maize sole cropping (T1), potato sole cropping (T2) and intercropping of potato: maize with planting row ratios: 1:2 (T3), 2:2 (T4), 1:1 (T5), 2:1 (T6), 2:2 (T7, in which 100% plant density was used for maize and 100% was used for potato), 1:3 (T8), 3:1 (T9), 2:3 (T10), 3:2 (T11), 4:2 (T12), 2:4 (T13), 2:2 (T14 in which 100% plant density was used for corn and 50% was used for potato). The experimental design was randomized complete block design with three replications. Results showed that the highest maize yield (11690 kg ha-1) was obtained in treatment T8 (1 row of potato and 3 rows of maize) which was higher than that in maize sole cropping. The highest potato tuber yield (16010 kg ha-1) was produced in potato sole cropping. The highest LER was obtained in T8 (1.61). It is concluded that potato:maize intercropping with planting row ratios of 1:3 was more suitable in early spring planting in Jiroft region in Iran. |
