      abstract = {This study was carried out in the Teaching and Research  Farm of Delta State University, Asaba Campus (Nigeria) from  March to December in 2008 and replicated between March and  December, 2009, to evaluate the effects of variety and  spacing on yield indices of Open-pollinated maize. It was a  factorial experiment carried out in a Randomized Complete  Block Design (RCBD) with four replicates. Four  open-pollinated varieties (Suwan -1- SR, ACR97,  BR9922-DMRSF2 and AMATZBRC2WB) were evaluated under three  different plant spacing for such yield indices as number of  cobs/plant, cob length, grain weight and number of  grains/cob of maize. The results obtained indicated that  variety BR9922-DMRSF2 was outstanding with number of  cobs/plant of 1.7 in both 2008 and 2009, cob length of 27.7  cm and 26.7 cm in 2008 and 2009, respectively. Its grain  weight was 4.7 t/ha in 2008 and 4.9 t/ha in 2009, and its  number of grain/cob was 467.7 in 2008, and 463.9 in 2009.  Plants sown at spacing of 75 cm x 15cm had higher number of  cobs/plant of 1.9 in both 2008 and 2009.Their grain weights  (t/ha) were 5.0 in 2008 and 5.2 in 2009, their cob lengths  were 18.6cm in 2008 and 20.1cm in 2009, while their number  of grains/cob were 363.0 in 2008, and 369.0 in 2009. The  results of interaction showed that except variety x space,  the parameters investigated were all significantly (P <  0.05) different and affected yield indices of  open-pollinated maize. Based on the findings of the study,  it was recommended that (i) open-pollinated variety  BR9922-DMRF2 be grown in the study area for increased grain  yield indices of maize. (ii) Plant spacing of 75 cm x 15 cm  which resulted in higher number of cobs/plant and higher  grain weight be adopted in maize production.},
