in order to investigate the effects of fertilizer types and irrigation regimes on quantitative criteria of three medicinal plants: lavander, rosemary and hyssop, an experiment was conducted at research field of faculty of agriculture, ferdowsi university of mashhad, during two growing years of 2007-2010. a split-split plot design with three replications was used. treatments were three irrigatio...

The two greatest silage problems are shrinkage (dry matter losses) and heating (aerobic spoilage). Therefore, one of the main aims of silage making is to reduce losses of dry matter during the preservation process. Dry matter losses occur during the three main stages of silage preservation namely the aerobic respiration stage after cutting, the anaerobic fermentation stage after sealing, and th...

this experiment was carried out to study the effects of corn and green gram intercropping on yield and some quality characteristics of forage at agricultural research station of gorgan during summer 2006 & 2007. the experimental design was a randomized complete block design (rcbd) with twelve treatments and four replications. a local green gram and corn single cross 550 were the crops used in t...

Anaerobic digestion of dairy cow manure (CM), the organic fraction of municipal solid waste (OFMSW), and cotton gin waste (CGW) was investigated with a two-phase pilot-scale anaerobic digestion (AD) system. The OFMSW and CM were digested as single wastes and as combined wastes. The single waste digestion of CM resulted in 62m3 methane/ton of CM on dry weight basis. The single waste digestion of...

Monensin 3 , a polyether antibiotic, was blended with a forage diet at levels of 0, 11, 22 and 33 ppm and fed to steers to determine its effect on cot ton fiber, dietary carbohydrate and nitrogen digestibility, on numbers of rumihal microbes, and on concentration of ruminal volatile fa t ty acids. No differences (P>.10) in cellulose digestibility from cot ton were observed in response to monens...
