Normalized difference vegetation index (NDVI) is a non-destructive measure of green vegetation growth or above ground biomass of a crop. NDVI may also be used to evaluate traits such as early vigour and stay green which are important for adaptation to drought stress. In the present study, the rel...

A collection of 64 accessions of the South American pasture legume Aeschynomene histrix Poiret was characterized in 1995 at Ibadan in south-west Nigeria in order to test the potential of the accessions as forage plants in subhumid areas and as a trap crop for the parasitic plant Striga hermonthic...

Relative importance of harvest index (I) and total biomass yield (B) to economic yield (Y) was assessed in several food crops at different levels of environmental productivity. Importance of B is generally higher in low than high yielding environments, while that of I is higher in high than low y...

Se evaluaron en invernadero en un suelo de Matazul, Meta, Colombia durante 6 semanas, 2 genotipos de Brachiaria (uno mejor adaptado a bajo P, B. decumbens y otro menos adaptado, B. ruziziensis) y 8 progenies del cruzamiento entre ellos ( mejores adaptados: H-7, H-40, H-28, H-58; menos adaptados: ...

In 1998, Fisher et al. attempted to draw together published and anecdotal information to answer some of the questions raised by the findings of Fisher et al. (1994; 1995), that introduced pastures of African grasses on the eastern plains of Colombia accumulated large amounts of C in the soil. Thi...

Between 1988 and 2000, changes in the above-ground biomass (AGB) of trees in an East Kalimantan lowland forest, damaged by fires in 1982-83 and 1998, were estimated using allometric functions and an annual inventory of stem diameter. The original vegetation of the study site was lowland dipteroca...

Biomass of a mature man-made forest in West Java, Indonesia, was estimated to evaluate the carbon sequestration potential of plantation forest in the humid tropics. Twenty plots, each 0.25 ha in area and containing one to six planted species over 40 years of age and with closed canopies, were sel...

The article followed the establishment and growth response of 13 commercial tree species to canopy opening, above-ground biomass removal, and experimental burns of low and high intensities in a lowland dry forest in Bolivia. Three patterns of response to treatments were observed among the most ab...
