In low-input land-use systems combining timber trees with shade-tolerant understorey crops, it is essential to establish the effects of tree density upon weeds and the contribution of weeds to competition and nutrient cycling. Adjusting tree density may alter weed competition for light, water and...


Norgrove, L.Hauser, S.Weise, S.F.[Response of Chromolaena odorata to different tree densities in a tropical agrisilvicultural system. Aboveground biomass production, partitioning, decomposition and nutrient release]Response of Chromolaena odorata to different tree densities in a tropical agrisilvicultural system.

In Cameroon, parasitism by Loranthaceae is a limiting factor of the avocado tree cultivation as well as the many diseases and pests which have been better studied. Inventories were carried out in the agroecosystems of five localities around Yaounde, Cameroon. In each one of these localities, all ...

Speargrass, Imperata cylindrica (L.) Raeuschel, is a serious weed, threatening crop productivity in smallholder farms in West Africa. Since the use of more effective practices such as deep tillage and chemical control is beyond the means of resource-poor farmers who carry out most agricultural ac...

The critical period of weed interference was investigated from 1982–1985 In two local cassava cultivars in Cameroon. Unweeded plots had more than 90% losses and were infested by birds and rodents which caused much damage to the fresh storage roots. One weeding round was not an effective treatment...

The use of agroforestry systems in which pruning from trees is used to mulch the companion crops is an important area of research in the tropics. However, previous studies mostly evaluated the contribution of mulch to soil improvement and rarely examined the effect of mulch on weeds. Field experi...

Populations of plant parasitic nematodes and their effects on symbiotic nitrogen (N) fixation in herbaceous legumes and on some selected characteristics of other plant species associated with such cover crops were studied. Two legume species [mucuna, Mucuna pruriens (L) DC. var. utilis (Wright) B...

Monoculture of irrigated rice (Oryza sativa L.) in Latin America has led to serious weed problems and intensive herbicide use. Yield loss prediction enables the economic analysis of weed control, providing a basis for strategic use of herbicides and diversified weed management, but site differenc...

This article is a result of a research project to characterize degrated sites in Pucallpa, Peru and determine the adaptability of six native tree species in areas abandoned after agricultural use. Nine farmers were selected for setting-up experimental plots on abandoned land characterized by Ulti...
