Sainfoin in believed as an important forage crop regarding its suitable agronomical characteristics and feeding livestock. Evaluation of general combining ability is a critical preliminary stage before selection of suitable parent and production of synthetic varieties. Thirty six sainfoin landraces which have been collected from different parts of Iran were grown in 2000 in a randomized complet...

In order to study fungi associated with seeds of sainfoin, several seed samples of sainfoin were collected from Isfahan, Ardabil, Zanjan and eastern Azerbaijan provinces, Iran. Seed lots, only half of which were surface sterilized, were allowed to grow on PDA, SMA, MA, sterilized wet paper and drenched sands. The dishes containing seeds were incubated at 25°C with alternate cycles of 12-hour fl...

The incorporation of plant residues in soils of arid and semiarid regions is a major principle of sustainable agriculture. This study was conducted at the research farm of Urmia University (37° 32’N and 45° 5’ E), Urmia, Iran during the 2009 and 2010 growing seasons. Five green manure crops were grown in four replications arranged in a randomized complete block design. The treatments included w...

This study was conducted to investigate the effect of formic and sulphuric acids on chemical composition, dry matter (DM) and crude protein (CP) degradability of alfalfa silage and its effect on early lactating Holstein cow as three trials. In the first trial, chopped alfalfa (22 and 33% DM) was ensiled with three levels of formic acid (0.0, 15 and 20 ml/kg DM) and two levels of sulphuric acid ...
