Assessing food production capacity of farms in periurban areas

Soil Fertility Map for Food Legumes Production Areas in China

Given the limited resources of fossil energy, and the environmental risks of excess fertilizer on crops, it is time to reappraise the potential role of food legume biological nitrogen fixation (BNF) as sources of nitrogen for cropping systems in China. 150 soil samples across 17 provinces and 2 municipalities of China were collected and analyzed. A distribution map of the soil fertilities and t...

Biomass production, antioxidant capacity and removal of nitrate and phosphate by marine microalgae Tetraselmis tetrathele cultivated in food wastewater

This study was conducted to investigate the cultivation of Tetraselmis tetrathele in food effluent and the effect of different concentrations of effluent on specific growth rate, biomass, chlorophyll a, chlorophyll b, total carotenoids and comparing them with Conway medium. Meanwhile, in this experiment, the percentage of phosphate and nitrate removal from food effluent by T. tetrathelewas eval...

molecular and physiological characterizations of floral scent production in rosa damascena mill.

گل محمدی (r. damascena mill.)مهمترین گونه ای است که در تولید گلاب، عطر و اسانس، در صنعت عطرسازی و دارویی کاربرد دارد. با وجود اهمیت عطر گل محمدی، پژوهش های مولکولی و بیوشیمیایی عطر گل این گونه هنوز در مراحل ابتدایی است. در این پژوهش، ویژگی های مولکولی و فیزیولوژیکی تولید عطر در گل محمدی در آزمایش های مختلف مورد بررسی قرار گرفتند. در آزمایش اول، پژوهشی به منظور بررسی تنوع شیمیایی اسانس میان 44 ت...

Issues in Caribbean Food Security: Building Capacity in Local Food Production Systems

Investigation of Energy Efficiency of Broiler Farms in Different Capacity Management Systems

An experiment was performed to investigate the energy efficiency and effect of poultry house size on energy productivity in 3 different capacity management systems. Capacities of houses were 10000(3 housings), 20000 (2 housings) and 28000 (1 housing) birds per production period and were assigned as HI, HII and HIII respectively. This experiment was conducted in a completely randomized design ap...
