| Abstract | ||
| The field experiment was conducted out at the Teaching and Research farm of Joseph Sarwuan Tarka University in Makurdi. during the 2018 and 2019 farming seasons to evaluate the performance of three groundnut varieties (SAMNUT 23, SAMNUT 24 and SAMNUT 25) in intercropping with maize at three levels of intra-row spacings (50 cm, 75 cm and 100 cm). The experiment was laid out in factorial arrangement in a Randomized Complete Block Design (RCBD) in three replications. The study revealed that the highest groundnut pod yields (2276.55kg/ha in 2018 and 2355.11kg/ha in 2019) in the sole cropping system, whereas in intercropping, pod yield (2090.07kg/ha in 2018 and 2165.24kg/ha in 2019) of groundnut were highest when combined with maize at 100 cm intra-row spacing. Groundnut variety, SAMNUT 23 had pod yields (1991.68kg/ha and 1959.84kg/ha) superior to other varieties in intercropping in 2018 and 2019 respectively. Groundnut pod yields in intercropped irrespective of varieties was highest at 100 cm and least at 50 cm intra-row spacing of maize. The highest maize output (1524.85 kg/ha and 1645.95kg/ha grain yields) in 2018 and 2019 respectively were achieved at intra-row spacing of 50 cm in intercropping with Groundnut variety, SAMNUT 24. The highest Land Equivalent Ratio of 1.30 and 1.32 were observed in 2018 and 2019 respectively when maize planed at intra-row spacing of 75 cm was combined with the Groundnut variety, SAMNUT 23. SAMNUT 23 intercropped with maize at 75 cm intra-row spacing is thus recommended for optimal intercrop yield in Makurdi. | ||
