Abstract: | Summary The effects of three water table (WT) depths (0, 15 and 40 cm) and calcium peroxide (Calper) on the growth and yield of cowpea
(Vigna unguiculata, L.) and soybean (Glycine max) were investigated in field lysimeters for a sandy loam soil. Cowpea growth was the best at 40 cm WT depth. Leaf area, plant
height, dry matter production, number of leaves and pods, grain yield and consumptive water use of cowpea increases with deeper
(lower) WT depth. Application of calcium peroxide improved per cent emergence, leaf area, dry matter, number of leaves and
pods, weight of 100 seeds, grain yield and water use in cowpea. The optimum WT depth for vegetative growth of soybean was
15 cm, although the highest grain yield was obtained at 40 cm WT depth. Number of pods, grain yield and water use efficiency
of soybean increased with deeper water table depth. Application of calcium peroxide to soybean increased number of leaves
and pods per plant, and grain yield for the 15 cm WT depth treatment. |
