Journal Article 1999

Autor: Kamara, A.Y. Chikoye, D. Jutzi, S.C.

The weed seed bank under seven fallow tree species was analysed in size and composition five years after tree establishment. The seed bank was lower in Enterolobium cyclocarpum fallows than in the other tree fallows at both 0-5 and 5-10 cm depths. Nuclea latifolia and Terminalia superba tree fall...

Weed seed bank size and composition were analysed in 1995 and 1996 in maize fields mulched with pruning from Gliricidia sepium, Leucaena leucocephala, and Senna siamea in South Western Nigeria. Plots mulched with pruning from the three trees had a lower weed seed bank in the first year of croppin...

Cutting and carrying of mulch from established tree plots is an alternative to in situ mulch in agroforestry systems. Through the cut-and-carry method, the undesirable e ects of tree-crop competition characterized by in situ mulching can be avoided. An economic evaluation of the cut-and-carry met...

Soybean (Glycine max) is a major cash crop in the savannas of Nigeria although productivity is typically constrained by poor soil fertility. The objective of this research was to determine the interactive effect of N and P on soybean productivity in the northern Guinea and Sudan savannas of north...

Striga hermonthica is a serious biotic constraint to sorghum production in the dry savannas of subSaharan Africa but the use of improved cultivars and appropriate planting dates may help to control the weed. A two year trial was conducted to evaluate the effect of sowing dates on four sorghum cul...

Field trials were conducted in 2005 and 2006 in Tilla (northern Guinea savanna) and Sabon-Gari (Sudan savanna) in northeast Nigeria to determine the performance of two improved cowpea varieties when relay-intercropped with early and late maize, 6 and 8 weeks after planting the maize. Grain yield,...

Sorghum (Sorghum bicolor [L.] Moench) is one of the most important cereal crops grown in the dry savannas and semi-arid regions of West Africa under rain-fed conditions. Although total sorghum production in Nigeria has increased over the years, the average grain yield on farmers' fields has remai...
