The reproductive output of Shorea siamensis, a widespread dipterocarp tree, was assessed in relation to disturbance and tree density at three sites in western Thailand during the 1996 and 1997 flowering seasons. The locations were similar except in disturbance history, which was reflected in decr...

The mating system in 11 natural populations of Pterocarpus macrocarpus Kurz in Thailand was investigated based on the mixed mating model using 16 isozyme markers. Single-locus outcrossing rates (tm) ranged from 0.719 to 0.959. Both ts and tm revealed a geographic pattern with western populations ...

Traditionally, Indian farmers kept bovines, especially cattle, for draught purposes in agriculture and transportation with milk as an adjunct. However, with increasing farm mechanization and rising demand for milk, the bovine functions have shifted more towards dairying. While bovine population h...

With a limited number of cash cropping areas, sub-Saharan Africa has the lowest level of mechanization including animal-driven implements and use of tractors. In this paper previous research is reviewed to evaluate the economic and ecological constraints to animal draft cultivation. Results of pa...

Agriculture is the mainstay of the country and also the major source of employment and income. About 85 percent of the population live in the rural areas and are primarily engaged in agriculture and related activities. Among the other agricultural sector, livestock production contributes about 30...

Although Ethiopia has abundant land for irrigation, only a fraction of its potential land is being utilized. This study evaluates suitability of lands for irrigation using groundwater in Ethiopia using GIS-based Multi-Criteria Evaluation (MCE) techniques in order to enhance the country's agricult...

Owing to the reduction of population density and/or the environmental changes it induces, selective logging could affect the demography, reproductive biology and evolutionary potential of forest trees. This is particularly relevant in tropical forests where natural population densities can be low...
