Chemical-mechanical separation of pig slurry into a solid fraction rich in dry matter, P, Cu and Zn and a liquid fraction rich in inorganic N but poor in dry matter may allow farmers to manage surplus slurry by exporting the solid fraction to regions with no nutrient surplus. Pig slurry can be applied to arable land only in certain periods during the year, so it is commonly stored prior to fiel...

Twenty-four multiparous Holstein cows were used in six 4×4 Latin squares with 28day periods to determine inclusion rates for wet corn gluten feed (WCGF) in diets for lactating dairy cows. Cows were housed in a tie-stall barn and fed diets to meet or exceed NRC (1989) nutrient requirements. Experimental treatments were 1) control, 2) WCGF constituting 20%, 3) WCGF constituting 27.5%, and 4) WCGF...

this experiment was conducted to study the effect of plastic mulch on the growth and some physiological characteristics of two strawberry cultivars (paros and queen elisa) under drought stress. a factorial experiment was performed based on randomized complete block design with four treatments, including mulch, without mulch, normal irrigation (control) and deficit irrigation (-10 bar) with thre...

Tassel traits are important in maize breeding programs aiming to reduce the size and number of branches and maintain satisfactory pollen production in order to increase grain yield. The objectives of this study were to determine the sample size (number of tassels) required to estimate the mean values for tassel traits in maize genotypes and to verify the variability of sample size among genotyp...

This experiment was conducted to study the effects of various amounts of treated sunflower meal (SFM) with extracted tannins from pistachio hulls on in vitro gas production and ruminal fermentation in ruminants. The SFM was treated with pistachio extract concentrate (PEC), which contained 111.40 g kg-1 total phenol and 71.30 g kg-1 total tannin per dry matter of e...

Sunflower is one of the most important edible oil that growth of annual crops, it is grown over a widely area and is considered a crop adapted to an every environmental conditions, in order to study growth analysis of sunflower under sowing date and cultivars in dry condition a farm experiment was conducted a split plot arranged in a complete randomized block design with three replications in t...

abstract the aim of this experiment was the study of freezing tolerance of bellis perennis under controlled conditions and were arranged in a completely randomized design with three replications. plants after sowing and grow in the bed, at the middle of autumn (after hardening in natural conditions), in the 7-8 leaf stage put on the thermogradiant freezer with the 12 freezing temperatures (0,-2...
