Summary

The yield of Chipewa variety of soyabean was investigated in relation to spacing and fertilizer levels on a range of paddy soils exhibiting good, medium and poor drainage. Under good conditions of drainage optimum yield was obtained at a density of 100,000 plants/ha and a fertilizer level equivalent to N—54, P2O5—54, K2O—75 and MgO—9 kg/ha. Under poorer conditions of drainage yield continued to increase up to a density of 162,000 plants and fertilizer levels of twice the above rates. Even under sub-optimal drainage conditions, however, satisfactory yields equivalent to about 1500 kg/ha were obtained from this variety.
