in order to select and release of nassim, a new cultivar of red clover, the researcher carried out the researches at the field of seed and plant improvement institute (spii) in karaj and some research stations such as shahrekord, sanandej, kermanshah, arak, gorgan during years 1996-2006. the experimental research was carried out design rcbd with six treatments and four replications during years...

To assess the effect of non chemical management of weed control on forage Sorghum (Sorghum bicolor) a field study was conducted in Varamin, Iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (W1= one time cultivation at 3-leaf stage using a duck foot cultivator, W2<...

The second occurs in late spring and early summer (May to June) when wheat has ceased growth and warm-seaThis study was conducted to determine seasonal forage production son pastures are not yet available for grazing (Northup, and nutritive value of the cool-season annual legumes grasspea (Lath2003). New plant species that can fill these gaps with yrus sativus L. cv. AC-Greenfix) and lentil (Le...

The objective of this study was to investigate the effects of concentrations of forages and dried distillers grains with solubles (DDGS) on production of lactating dairy cows. Twelve Holstein cows were assigned randomly to replicated 4 × 4 Latin squares in a 2 × 2 factorial arrangement of treatments. Diets were formulated containing low forage (LF; 41% of diet DM) or high forage (HF; 60% of die...

Maximizing P removal with cropping can increase regulated Pbased manuring rates or reduce soil test P in manure-enriched soils. The potential for increased P removal with winter forage–corn silage double cropping was evaluated in a 3-yr study at Parma, ID. Winter barley (Hordeum vulgare L.), and both winter and spring genotypes of wheat (Triticum aestivum L.) and triticale (3Triticosecale Wittm...

To assess the effect of non chemical management of weed control on forage Sorghum (Sorghum bicolor) a field study was conducted in Varamin, Iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (W1= one time cultivation at 3-leaf stage using a duck foot cultivator, W2<...

with those choosing to grow wheat as a forage-only or GO crop (Redmon et al., 1995), but they need to follow Winter wheat (Triticum aestivum L.) is the foundation of many a recommended set of management practices to optiagricultural enterprises in the southern Great Plains and is grown primarily as either a grain-only (GO) or a dual-purpose (DP, grazing mize returns. plus grain) crop. Tradition...

Various recommendations have been issued regarding the sampling schedule of diet components, especially forages. Their basis is unclear and none are justified from an economic standpoint. The objective of this research was to derive a general method for determining the optimal sampling design for forages. The process of forage removal from storage can be conceptualized as a quality control issu...

Targhee ewes with single or twin lambs were used in four trials during early lactation through weaning to evaluate ewe milk production (MP), kilograms of lamb weaned, and forage intake by ewes and lambs. During Trial 1, ewes with lambs were individually penned, fed .45 kg of barley-ewe-1.d-1 and allowed ad libitum access to chopped alfalfa hay. Trials 2, 3, and 4 were conducted on three differe...

Plant growth promoting rhizobacteria (PGPR) have originally been defined as root-colonizing bacteria that cause either plant growth promotion or biological control of plant diseases. The mechanisms by which PGPR promote plant growth are not fully understood, but it is believed that the plant growth promoting rhizobacteria enhance plant growth and yield either by direct or indirect mechanisms. T...
