Tillage affected germination. It was highest with the rototiller, where aggregate sizes favored good seed-soil contact and the highest soil moisture content. Soil penetration resistance recorded at pegging stage was least in the rototiller treatment. Haulm and pod yields were highest in the tractor-drawn treatment, closely followed by those with the rototiller. The higher yields obtained with tractor tillage compared with bullock-drawn treatments might be due to the deeper plowing, which resulted in the breaking of the subsoil hardpan layer and smaller aggregates. Higher yields with rototiller was due to uniform aggregates size and low soil strength (penetration resistance)
