400 one day-old broiler chicks were allocated on a randomized complete design experiment with five treatments consisting of four replications for 42 days. experiment treatments were included: 1 . based diet consist 20 percent barley (barley control), 2 . barley control + 0.1 percent of mixed essential oil (antibiofin), 3 . barley control + 0.2 percent organic acid, 4 . barley control + 15 ppm o...

this study was carried out to determination of in vitro binding capacity of organic (wheat and barley) and inorganic (perlite) sources for mn, zn, cu, and fe. for this reason wheat and barley were analyzed chemically for moisture, protein, ash, and ether extract, total carbohydrate, ndf, adf, adl, crude fiber, viscosity, cellulose, and total dietary fiber. the in vitro mineral binding capacity ...

improvement of soil properties through sustainable agriculture requires suitable management of plant residues. this study was conducted to investigate the effect of different types and managements of plant residue on soil physical properties in a field experiment as factorial based on rcbd with three replicates. the first factor was residue type including barley straw and alfalfa residue, and t...

The objective of this study was to determine whether supplementing organic acids can prevent incidences of subacute ruminal acidosis (SARA) in beef heifers fed a diet consisting of 8% barley silage and 92% barley grain-based concentrate (DM basis). Ten ruminally cannulated Hereford crossbred heifers (484 ± 25 kg BW) were used in a replicated 5 × 5 Latin square design with 14-d periods including...

effects of drought stress and chemical treatments was studied on growth and developmental traits of four barley cultivars using a split- split plot design (rcbd) in agricultural research farm, kerman university. main plots consisted of irrigation (control and drought stress after flowering), sub-plots consisted of four barley cultivars ( ʻnosratʼ, ʻafsalʼ, ʻyousofʼ and ʻuh12 lineʼ) and sub-sub ...

this study was conducted to study the effect of organic acids on the preservation of alfalfa nutritional value after harvesting. a split plot design with 4 treatments and 3 times was conducted in which organic acids were sprayed on the 30percent moisture content forage before baling. treatments were: 1) forage without additives as control, 2) pure propionic acid, 1percent, 3) acetic acid percen...

effects of drought stress and chemical treatments was studied on growth and developmental traits of four barley cultivars using a split- split plot design (rcbd) in agricultural research farm, kerman university in 2013-14. main plots consisted of irrigation (control and drought stress after flowering), sub-plots consisted of four barley cultivars (ʻnosratʼ, ʻafsalʼ, ʻyousofʼ and ʻuh12 lineʼ) an...

Responses of soluble amino acids and organic acids to either ambient (36 Pa) or elevated (100 Pa) CO2 treatments were determined using barley primary leaves (Hordeum vulgare L. cv. Brant). Total soluble amino acids were increased 33% by CO2 enrichment 9 days after sowing (DAS), but a decrease relative to the ambient CO2 treatment was observed with increasing leaf age. Marked declines of glutami...

background and objectives: suitable tillage methods and planting cover crops are such factors in sustainable agricultural systems, which play an important role in the sustainability of agricultural production systems. minimum and no-tillage systems methods that leave instead of usually more than 30 percent of crop residue on the soil surface, are used to reduce soil erosion, improve soil physic...

objective:  in addition to the role of organic matter in plant nutrition, this material improves soil quality, physical structure, ventilation and water supply, and ease of penetration and expansion is rooted deep in the soil surface. effects of organic matter due to climatic factors, soil characteristics may vary from region to region, resulting in organic materials management must be given to...
