Reputation effect of the moral hazard on contract farming market development: Game theory application on rice farmers in Benin

A good reputation is the basis for rice farmers to survive and gain trust from buyers in a competitive business environment. However, due to the existence of information asymmetry between buyers and rice farmers, the moral hazard problem is the key obstacle that impedes the benefits of related shareholders and hinders the efficiency of contract farming negotiations.

Sorption-desorption isotherms of diuron alone and in a mixture in soils with different physico-chemical properties

Herbicide mixture is a widely used weed control practice in many agricultural areas. However, interactions between the herbicide mixture and soil may alter the soil dynamics. This research evaluated the effect of the physicochemical properties of the soils in the application of diuron alone and in a mixture with hexazinone, by means of sorption-desorption Freundlich isotherms. 14C-diuron sorption (isolated and mixed)...
