The effects of spacings between hedgerows (alley widths) and the spacings of trees within hedgerows ofGliricidia sepium on growth and grain yield of maize were investigated at Senehun in southern Sierra Leone. Four between-row spacings (2, 4, 6 and 8 m) were combined with three within-row spacings (0.25, 0.50 and 1.00 m) in a split block design. Maize, at(More)
An investigation was undertaken at Senehun — Kamajei, a high rainfall region in Sierra Leone, to assess the effects of Leucaena leucocephala, on the growth and productivity of maize, cowpea and sweet potato. The experiment was laid out in a completely randomised design with four replicates of each treatment. The treatments and controls were: (i) pure crops(More)
The effect of cutting height and cutting interval on dry matter production of Leucaena leucocephala (Lam) De Wit was investigated at Njala, Sierra Leone using three year old Leucaena trees. Four cutting heights, (25, 50, 75 and 100 cm), and two cutting intervals (one and three months), were adopted. Dry matter yields were highest at the 75 and 100 cm(More)
The quantities of nitrogen, phosphorus and potassium supplied by an ‘average’ African soil cleared from bush fallow, assuming no losses, were approximated. Values ranged from 23 to 120 Kg N ha−1, 1.8 to 12 Kg P ha−1, 47 to 187 Kg K ha−1, depending on type of fallow, length of fallow, drainage and extent of depletion of native supplies. Additional amounts of(More)
