In order to evaluate the productivity of 20 bread wheat promising lines using multivariate statistical methods, an experiment was conducted based on a randomize complete block design under terminal moisture stress, in 2011-2012. Factor analysis showed that the three first factors explained 66% of total variance. Plant height, peduncle length, 1000 kernel weight, harvest index, biological yield,...

 To study the effects of plant density and species on forage and grain yield of Vicia sp., anexperiment was conducted in College of Agriculture, University of Lorestan, under dry farming conditions during 2007-2008 growing season. Three levels of plant density at 100, 150 and 200 seed per square meter along with three species of Vicia including Vicia narbonensis, Vicia sativa and Vicia dasycarp...

This research was carried out to determine the optimum conditions for acidic extraction of gelatine from cattle bones. The effects of different treatments such as pH (1.8 to 2.6), temperature (60 to 80°C) and time (40 to 120minutes) on yield of extraction, gel strength, viscosity and absorption (420 nm) was measured. Coefficients of central composite rotatable design (CCRD) and regression surf...

The moisture content of urban solid wastes in Iran is very high. A large volume of leachate is, therefore, produced in the process of converting these wastes into compost. The leachate contains relatively large amounts of organic matter, plant nutrients, soluble salts as well as small amounts of some heavy metals. The effects of urban solid waste leachate on growth and yield of corn and heavy m...
