Sorghum grain yields under the karité and the néré are reduced by an average of 50% and 70% respectively, in comparison with yields in the open field. Soil fertility, limiting primary production in the region, is at least as favorable under the tree canopies as in the open field. Reduced light...
Management of hillside cropland is a critical issue in the tropical world because of the extreme pressure on the land itself that results from the decision to farm what would be considered in many countries as marginal land.
Relative windspeed reduction was measured behind nine relatively narrow, homogeneous windbreaks in southern Ontario, Canada to assess whether any characteristics of the windspeed reduction curve could be predicted from optical porosity. The latter was determined for each windbreak using high...
The effect of browse supplementation on maize husk (Zea mays) utilization by goats was studied in a 12 week feeding and 2 week digestibility trial. Twenty-four goats were stratified according to their weight, and then randomly allocated to four treatments. Browse supplementation significantly...
Forage and wood yield of Acacia cyanophylla, also known as Acacia saligna, was studied in a 300–400 mm precipitation zone in Tunisia. Yields were measured during and after drought. This short (2–8 m) evergreen leguminous tree is used as a forage drought reserve in frost free regions where mean...
Agroclimatograms are presented for assisting species selection in the tropics by analyzing agroclimatological factors and similarities. The diagrams include data for temperature, precipitation, water budget and potential evapotranspiration (PET). A computer program to calculate the PET is...
A maize-leguminous tree alley cropping system was studied on N-deficient soils in Hawaii to determine mulch effects on maize yields. Calliandra calothyrsus, Cajanus cajan, Cassia siamea, Gliciridia sepium, KX1 — Leucaena hybrid (L. pallida X L. diversifolia), L. leucocephala, L. pallida, L....
