Effect of inter-row spacing on JengumaSoyabean Yield Components and Yield.

The study focused on effect of different inter-row spacing on the yield components and yield of JengumaSoyabean and yield. The experiment was carried out on a 0.2 ha plot at Nyankpala in Northern Region of Ghana. A Randomised Complete Block Design (RCBD) was used in the study in which four inter-row spacing (45 cm, 60 cm, 65 cm and 75 cm) were used. Plant population at establishment, population at harvest, plant population The study focused on effect of the different inter-row spacing on the yield components loss, weed biomass, number of pods per plant, number of seeds per pod, one thousand seed weight and grain yield were evaluated.The results from ANOVA showed that the narrow spacing had the highest plant population with low weed intensity. Grain yield correlated positively and significantly with plant population at establishment and plant population at harvest. The 45 cm inter-row spacing gave the highest grain yield. This study indicates that farmers can reduce the inter-row spacing required to produce Jengumasoyabean, without negatively impacting yield, at least in the study area.
