Abstract
The effects of various row spacing on the yield and yield components of okra with groundnut were conducted at the training and research farm of the Federal University of Technology, Owerri. Yield and yield components of the crops in the various row spacing, monetary value of fresh okra fruits and dry groundnut pods were determined. The efficacy of the inter-cropping on weed suppression was evaluated. Okra plant height showed that R30 (30x50 cm) was highly significant than the other treatments in the experiment. Treatment R90 (90x50 cm) and R75 (75x50 cm) had significantly higher number of branches (p=>0.05). The results show that productive nodes increased with increasing row spacing, R90 had 77%, while R75 and R60 had 69 and 66%, respectively. This actually affected crop yield. However, R75, R60 and R90 had the highest fruit yield and were significantly higher than R30 and R45 at p>0.05. Conversely, R30 and R45 suppressed weeds better but had low fruit yield compared to R75, R60 and R9d . The yield of groundnut showed that R60 and R75 had the highest yield although it was not significantly different from R90. Treatment R75 had the highest monetary yield of N 132,200.00 ha-1 than the other treatments compared.
