Abstract:
<p> There are an insufficient number of university students, specifically women, graduating with an education in agronomy to fill work force demands. This need, driven partially by population growth, is increasing due to growing rates of industrialization and consequential environmental issues. Agronomy pays special attention to the supply and demand of resources from the environment. Though there is an apparent regression in students choosing an education in agronomy, there is a need for their skill set. This study hypothesized that urban and rural women have different perceptions that influe

During outdoor trials under anaerobic saline soil conditions of paddy-style irrigation, D. palmeri exhibited high salt tolerance, grain and biomass production.

Its efficacy and lack of residual activity are therefore important to ensure adequate weed control without imposing hazards to the environment. Despite these favourable attributes for weed control glyphosate has its shortcomings. Evolution of resistance to glyphosate has been a major concern from 1996. However, there are other f
