One of the most important issues in rangeland management is the estimation of carrying capacity. To estimate range production, we need to use a large number of sample plots to clip plants in a sampling scheme; therefore, due to vast area of rangelands and time and cost limitations, direct estimation of rangeland production by sampling plots […]
To find an accurate and rapid method of estimating herbage crop, Double Sampling (DS), Comparative Yield (CY), and clipping and weighing (CW) methods were applied to a summer rangeland in North-eastern Alborz Mountains, Iran. The method was called SMFY (Simulation Model of Forage Yield) to emphasize the statistical aspects of simulated model. In representative stands […]
Colocynth (Citrullus colocynthis) is one of the major medicinal plants, naturally growing in deserts of Middle East and North Africa. Extending cultivation of this species is useful for sand dune fixation and livelihood of the local inhabitants. In spite of numerous studies on seed germination, there are still debates on the best methods of breaking […]
