Interactions among leguminous trees, crops and weeds in a no-till alley cropping system
Trees improve the soil quality and their rapid growth in the tropics make agroforestry systems potentially effective for establishing low-input agricultural systems in this region. This study assessed the effects of the biophysical interactions among leguminous trees, weeds, cotton and maize in an alley cropping system. The experiment comprised six treatments: Clitoria + Gliricidia; Acacia ...

متن کاملInfluence of environmental factors on the sap flux density of mango trees under rain-fed cropping systems in West Africa
Xylem sap flux density (Fd) was measured, on a 43-year-old (mature) and three 4-year-old (young) mango (Mangifera indica L.) trees, using Granier-type probes. The relative influences of environmental variables were examined under well-watered condition. Circumferential variation in Fd was also investigated by placing sensors on the north, south-west and south-east sides of the mature tree. Sap ...
متن کاملMeasure and comparison of economic, social and ecological sustainability of farming systems in the Marvdasht plain
