introduction canary seed (phalaris canariensis l.) is a forage plant from poaceae family. this plant is drought tolerant. canary seed is originally a native to mediterranean region, which can be grown commercially in several parts of the word, especially in semi-arid conditions. increasing growth of population and lack of ability of pastures to satisfy the food requirement of animal has led to ...

Mix cropping of alfalfa (Medicago sativa) and annual ryegrass (Lolium rigidum) may improve forage production in the rangeland and field conditions, especially in spring after the establishment year. In this study, the effects of different sowing rates of alfalfa and annual ryegrass seeds in the replacement and additive series of mix cropping were evaluated on forage yield in first year after th...

Perennial ryegrass (Lolium perenne L.) is one of the most widely grown forage grasses in temperate agriculture. In order to maintain and increase its usage as forage in livestock agriculture, there is a continued need for improvement in biomass yield, quality, disease resistance, and seed yield. Genetic gain for traits such as biomass yield has been relatively modest. This has been attributed t...

This experiment was conducted in the Agriculture College of the University of Lorestan in 2007. To study morphological structure of stomata and forage yield in three species of forage vetch (Vicia sp.), a factorial experiment on the basis of a complete randomized block design (RCBD) with three replications was performed. The experimental treatments were three plant densities (100, 150 and 200...
