EFFECTS OF YEAR, SEASON AND SOWING PERIOD ON GRAIN YIELDS AND YIELD COMPONENTS OF MAIZE-COW PEA INTERCROP IN ILE-IFE AND ABEOKUTA, SOUTHWESTERN NIGERIA.
An investigation of the influence of cropping year (2003-2005), season (early and late) and cowpea sowing dates (0. 14. 28. 42 and 56 days after maize sowing) on yield and yield component of mave (cv DMRE SR-Y) and cowpea (cv OLOYIN) in intercrop was conducted at the Teaching and Research Farms of O...

| description | An investigation of the influence of cropping year (2003-2005), season (early and late) and cowpea sowing dates (0. 14. 28. 42 and 56 days after maize sowing) on yield and yield component of mave (cv DMRE SR-Y) and cowpea (cv OLOYIN) in intercrop was conducted at the Teaching and Research Farms of Obafemi Awolowo University, Ile-Ife (latitude 7o 28' N and longitude 4o 33' E) and University of Agriculture, Abeokuta (latitude 7o 9' N and longitude 3o 21'E). The two sites were located in the rain forest zone and derived savanna zone of south western Nigeria, respectively. The study was in a split-plot design with three replications. At Ile-Ife, maize grain yield increased from 2.47 t/ha in 2003 to 2.63 t/ha in 2004 and later decreased to 1.64 t/ha in 2005 also at Abeokuta the highest grain yield was obtained in 2004 (2.85 t/ha) followed by 2003 with 2.22 t/ha while the grain yield in 2005 was the least (0.75 th). The sowing year and season effects of OLOYIN as component crop had no significant effect on grain yield and yield component of maize (cv DMRE SR-Y] but were highly significant on grain yield and yield component of OLOYIN at the two locations. The late season cowpea produced significantly higher grain yield compared to the early season crop. Sowing cowpea at 28, 42 and 56 days after planting maize caused significantly decrease in yield and yield components of cowpea. Delay after 14DAP caused significant decrease in yield in the order of 56%, 72% and 90% at Ile-Ife and 48%, 77% and 96% at Abeokuta for 28, 42 and 56 days, respectively after planting of maize. |
