Studying plant phenology is very important to regulate the rangeland utilization. Plant phenology can be determined by Growing Degree Days (GDDs). Since temperature varies yearly, the phenological stages may consequently differ yearly. Determining the base temperature is one of the key steps in the calculation of GDDs. The aim of this study was to calculate […]
Zagros forests are one of the important natural ecosystems in Iran with high plant diversity and variety of plant communities. In recent decades, fire events have frequently occurred in some of these ecosystems. The purpose of this research is to investigate the composition and diversity of herbaceous species after nine years of fire occurrence in […]
In the rangelands of Iran, the lack of appropriate grazing management is one of the major problems ultimately leading to untimely and excessive grazing intensity of forage. Accordingly, most of the rangelands show a retrogression trend and poor conditions. In forage species, phenological stage is one of the most important criteria for range management. Bromus […]
The Artisanal and Small-scale Gold Mining (ASGM) activities has become the main source of income for the local people in Sekotong sub-district since 2008. However, the decreasing gold production enforce them to leave the ASGM activities and work back to the agricultural sector. The study aims to evaluate and develop a crop and beef cattle […]
Estimation of long-term pasture production using important factors of climate and soil characteristics on forage production is inevitable. Reduced water and precipitation is important factor limiting production of fodder, especially in arid and semi-arid areas. Water use efficiency in these areas is the amount of water stored in the root orientation early in the growing […]
The survey was conducted in Urban and peri urban areas of mid and high land of Bale, Ethiopia during September 2016 to June 2017 with the objective of identifying available feed resources, its utilization methods and constraints related to feeding. The three major towns of Bale zone Ginir, Goba and Robe and the villages surrounding […]
A study was conducted in May–July, 2019 to determine the nutritional values of selected forages consumed by ruminants in the derived Savannah zone of Nigeria. The leaves of plant species were separated, identified, washed, screened, air-dried and milled for chemical analyses and in vitro degradability measurement. Three West African Dwarf rams were used to ascertain […]
One of the main factors to decrease water quality in rivers is land use changes. This study was conducted to choose the best way for land use management in order to increase water quality related to the least turbidity, improving natural landscape quality and attracting ecotourism. So, the effect of land use changes on turbidity […]
Before starting any classical breeding program on plants, it is necessary to dominate the fertilization behavior of that plant. Despite a large number of Salvia species in the flora of Iran, there is little information about the breeding system of this genus. In the current study, the flower specifications and breeding system of seven Salvia […]
This book brings together and discusses information relating to animal production systems in different parts of the world. Throughout this book there are examples of systems comprised of a collection of interdependent and interactive elements that act together to accomplish a desired outcome. As indicated in the Editor’s Preface, we sought to give a broad […]
