introduction bean (vicia faba l.) has the great old history of crop cultivation to date would be pushed back to a fairly long day plant, resistant to frost and cool season crop and up to 5 degrees celsius tolerated. bean prefers wet and cold conditions. excessive heat may cause fetal growth problems, loss and reduce the number of seeds per pod bean flowers to the growth of plant and fruit set o...

The effect of nitrogen fertilization of maize on fermentability of maize grain in the rumen was studied by means of in vitro method based on the measurement of gas produced during the incubation of samples with rumen liquor. Gas production was recorded continuously up to 72 h incubation time and cumulative gas production was described by the Gompertz equation Y=A*exp(-exp(-d*(t-tm))). Seven tre...

To assess the impact of S fertilization on bahiagrass (Paspalum notatum) quality and Cu metabolism in cattle, two studies were conducted during the summer grazing season (1999 and 2000). Pasture replicates (16.2 ha; n = 2/treatment) received the same fertilizer treatment in each growing season, consisting of 1) 67 kg N/ha from ammonium sulfate (AS), 2) 67 kg N/ha from ammonium nitrate (AN), and...

forage is the main product of rangelands. so, determining its economic value as one of the main important nonmonetary functions can help managers to improve planning and optimal utilization management of rangelands. the main purpose of this study is to estimate the economic valuation of the forage of summer rangelands in nour-roud watershed basin in mazandaran province. consequently, total fora...

kochia scoparia is a salt resistant plant that can be used in producing forage in the areas with salt water and soil resources. one of the problems which produce the forage plants in these areas decreases the function and quality of the forage in irrigation condition with salt water. therefore, using the chemical fertilizers can be considered as a useful solution. this study was conducted to ev...

In recent years, prices for N fertilizer have increased dramatically, reducing net returns of fertilized pasture systems. A 5-yr study from 2005 to 2009 was conducted to evaluate management strategies and relative differences in profitability for 3 methods of backgrounding calves on smooth bromegrass pastures. Forty-five steers were used each year for a total of 225 animals in a randomized comp...

In the conditions of a long stationary experiment conducted in Saratov region on Southern Chernozem, it was found that for eight rotations six-field grain-pair crop rotation (48 years) variant without fertilization, carbon losses from 0-40 cm layer were highest. Fertilizers N32P16K7 and N38P13K8 per 1 ha area reduced its by 29-32%. When applying N54P17K7, an increase migration organic into unde...

In recent years, there has been a growing interest in brown midrib (BMR) sorghum (Sorghum bicolor (L.) Moench.) · sudangrass (Sorghum sudanense Piper) hybrids (SxS) as a replacement for silage corn (Zea mays L.) in the north-eastern USA. Recent studies suggest it is suitable for both rotational grazing and as a hay crop and could compete with corn harvested for silage in years when wet spring c...

Liu G.D., Morgan K., Hogue B., Li Y.C., Sui D. (2015): Improving phosphorus use efficiency for snap bean production by optimizing application. Hort. Sci. (Prague), 42: 94–101. Phosphorus (P) is essential for crop production. Adequate application P rate is critical for enhancing productivity and profitability of snap bean (Phaseolus vulgaris L.). The goal of this study was to optimize P applicat...
