aData were combined over years (2014 and 2016). PH = plant height; PPP = pod per plant; SPP = seed per pod; SY = stover yield; GY = grain yield; TSW = thousand seed weight; SA = spatial arrangement; PT = planting time
*, **’*** are significant at 0.05, 0.01, 0.001 probability level, respectively and Ns is non-significant at 0.05 probability level.
