in order to study the effects of sowing date and plant density on forage yield and some morphological characteristics of corn, an experiment was conducted in gorgon research station in 2008. in this experiment two sowing date (18 april and 21 june) and six plant densities (25000, 45000, 65000, 85000, 105000, and 125000 plant per hectare) were evaluated in form of factorial experiment (2×6) with...

to evaluate the effect of nitrogen fertilizer amounts on grain yield of forage corn in 2012, a pilot was implemented in islamic azad university agricultural research station, isfahan, as a split plot in a randomized complete block design. main plots consisted of four levels: control (no fertilization ) , 50 , 100 and 150 kg per ha nitrogen from urea source and subplots , including several varie...

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...

Preservation of forage crops as silage offers opportunity to avoid the high risk of rain-damaged hay in the humid south-central USA. Recent developments with baled silage or baleage make silage a less expensive option than typical chopped silage. Silage has been important in the region primarily for dairy production, but baleage has become an option for the more extensive beef cattle industry i...

Suwarno, Wittenberg, K. M., Ingalls, J. R. and McCaughey, W. P. 2000. Performance of lactating dairy cows fed macerated forage conserved as silage and hay. Can. J. Anim. Sci. 80: 123–129. The effect of forage maceration at harvest on silage characteristics and its effect on lactation performance of Holstein cows were determined. Either a roller conditioner or a prototype forage macerator manufa...

Effects of eutrophication on the relative importance of nutrients and macroherbivores as controls of microphytobenthic standing crop were examined in estuaries with different nitrogen loading rates: Sage Lot Pond (14 kg ha–1 yr–1), Green Pond (178 kg ha–1 yr–1), and Childs River (601 kg ha–1 yr–1). We selected 5 sites with similar salinity ranges on shallow-water, sandy substrates per estuary. ...

A study was done to determine the macroand micronutrient requirements of young northern highbush blueberry plants (Vaccinium corymbosum L. ‘Bluecrop’) during the first 2 years of establishment and to examine how these requirements were affected by the amount of nitrogen (N) fertilizer applied. The plants were spaced 1.2 · 3.0 m apart and fertilized with 0, 50, or 100 kg ha of N, 35 kg ha of pho...
