Abstract
A lagoon (irregularly shaped depression) of 2-1 ac was levelled by filling with soil from the surrounding land, to give a levelled area of 4 ac. Maize, forage sorghum and a sorghum/Sudangrass hybrid were grown on the levelled area in 1964-6. DM yields on this area were 3500 lb/ac for maize, 4030 lb/ac for sorghum and 4620 lb/ac for the sorghum/Sudan grass hybrid, these yields being, 2000, 610 and 40 Ib, respectively, more than those on unlevelled land. Crops on the levelled area yielded an average of 830 Ib more DM/ac per year than crops on unlevelled areas. Levelling the lagoon gave more uniform distribution and efficient use of impounded runoff water. It was concluded that the ratio of runoff-contributing area to levelled area should be about 3: 1 and no greater than 5: 1. At a ratio of 5: 1, more efficient water use might be possible by sowing deep-rooted crops such as lucerne or smooth bromegrass.-M.R.H.
