in order to evaluate a better sowing date of chickpea cultivars in dry land conditions, a factorial experiment in randomized complete block design with four replications was carried out at research station of bahar (hamadan province) during 2005-2006 cropping season. two planting time included winter and spring and four chickpea cultivars (cvs.) including one local (check) and three improved cv...

The amount of manure produced on dairy farms can affect the financial bottom line. Labor, equipment, and facilities are needed to move and store manure, all of which have a cost. Increased output of manure can represent losses in potentially digestible nutrients (increased feed costs). Lastly, the environmental impact of dairy farming is strongly related with the quantity and composition of man...

abstract. information on forage quality in phenological stage could help range managers to choose suitable grazing method to achieve higher animal performance without detriment to vegetation. vetiver grass (vetiveria zizanioides) is a non-native perennial grass that was introduced to the iran in 2008. this plant is a multi use species that could be considered from different viewpoints. thus, it...

throughout the present study some vegetative and reproductive characteristics of rosa damascene fewer than three different irrigation regimes (100, 70 and 40% of potential evapotranspiration) through an application of surface vs subsurface drip irrigation systems were investigated. some morphological characteristics investigated, included the number of branches per plant, shading diameter, plan...

one of the effects of reducing water content on soil is reduction of growth and development of seedlings and variation of field development of them. it was found that seed priming improves some characteristics of seedling and plant. an experiment was conducted for evaluating the effect of seed priming by salicylic acid on some characteristics of barley seed at early growth stages, antioxidant e...

effect of electron beam irradiation on degradability coefficients and ruminal- postruminal digestibility of dry matter and crude protein of soybean meal, canola meal and lathyrus sativus seed, irradiated at doses of 50, 100 and 150 kgy was investigated. ruminal degradability of dry matter and crude protein was determined by in situ method using two cannulated holstein heifers. ruminal- postrumi...

Wheat by-products are feedstuffs that vary in nutritional value, partly because of arabinoxylans that limit nutrient digestibility. Millrun is a byproduct from dry milling wheat into flour and contains varying amounts of the bran, middlings, screening, and shorts fractions. The digestible nutrient content of mill-run is not well known. Effects of xylanase supplementation (0 or 4,000 units/kg of...

to evaluate durum pasta quality traits, using international standards, a study was conducted on seven improved and local durum wheat varieties. the traits examined included grain vitreousity (i.cc. no. 129), grain hardness index (h.i.), yellow berry (y.b.(, black point (h.p.), hectoliter weight (h.l.w.), thousand kerne! weight (t.k-w.j, protein percentage (i.cc. no. 105.1), protein quality ...
