Soil fertility is the central axis of agricultural productivity. Different approaches are being exercised and applying appropriate rate chemical fertilizer one. A study was conducted in Pawe district to evaluate effects N, P, K S fertilizers on maize grain yield for two consecutive years. Including negative control 23,46,69,92 kg/ha 10, 20 30 P with 92 Kg & 2.5,5,7 kg were also combined the...

There are three approaches to health economic evaluation for comparing two therapies. These are (i) cost minimization, in which one assumes or observes no difference in effectiveness, (ii) incremental cost-effectiveness, and (iii) incremental net benefit. The latter can be expressed either in units of effectiveness or costs. When analysing data from a clinical trial, expressing incremental net ...

Recent studies of mutualism have emphasized both that the net benefit to participants depends on the ecological context and that the density-dependent pattern of benefit is key to understanding the population dynamics of mutualism. Indeed, changes in the ecological context are likely to drive changes in both the magnitude of benefit and the density-dependent pattern of benefit. Despite the clos...

the present study modeled how future terrestrial net primary productivity (npp) changes spatiotemporally for the eastern mediterranean biomes of turkey using carnegie ames stanford approach (casa) model, moderate resolution imaging spectroradiometer (modis) data, the four regional climate change scenarios (rcp 2.6, rcp 4.5, rcp 6.0 and rcp 8.5), and such ancillary data as percent tree cover, la...

the study on gender and net farm income of cassava-based farmers under individual land tenure system was done in abia state of nigeria. the main objective was to determine the net farm income (nfi) and the benefit cost ratio (bcr) of the cassava farmers by gender vis-aviz their income levels as well as food security in the state. a multi-stage random sampling technique was adopted while data we...
