| Abstract | ||||
| Two field trials were carried out at Shandaweel Agriculture Research Station (Sohag Govemorate) during 2008 and 2009 summer seasons to study response of maize grain yield to intercropping with three legume fodder crops under three sowing dates (simultaneous maize and interaopped crops sowing and sowing at 3 and 5 weeks after maize). A split plot design with three replicates was used. The main plots were devoted to the three legume crops, and the sub plots were allocated to sowing dates of legume crops. The data obtained indicate that all studied characters of maize, cowpea; guar and soybean were reduced as compared with solid crops. This reduction was higher in legume crops than maize. The intercropping system resulted in maize plant height espedally when the interaopped crops were planted at the same of maize planting date. Maize grain yield character and its components were significantly affected by intercropped crops and sowing date. The reduction in maize characters was higher when intercropped with guar than with cowpea or soybean, and at simultaneous (Tr) than delay sowing (T2) or (T3).The forage green yield of cowpea, guar and soybean were affected by intercropping system and sowing dates. The forage green yield at late planting dates (3 or S weeks after maize) was more decreased than those sown at the same date of maize. The results also showed that maize grain yield crop was dominant while intercropped crops were dominated , where the highest land equivalent ratio (LER) recorded 1.15 and monetary 776.96 when maize intercropped with soybean, sown at 5 weeks after maize followed by cowpea sown at the same maize planting date .While total actual grain yield loss (AYL) was positive with cowpea in the three sowing dates with range from 0.13 to 0.23 , indicating increase in grain yield by 13 to 23 %compared with solid crop .While AYL was negative with guar at the first and second sowing dates which indicate decreased in yield with this system. It could be conduded that intercropping maize with cowpea at the same date or with soybean at delayed sowing (5 weeks after maize) had favored the growth and yield of both crops. | ||||
