this research has been done for studying the effect of split application of nitrogen fertilizer on growth indexes and yield of three hybrids of grain corn in shahrood. a split plot experiment based on randomized complete block design with four replications was carried out in 2007. three hybrids of corn (double cross 370, single cross 447, single cross 499) were placed in main plots and split ap...

wheat flour is known as the best nutrients supplier for human. in this research, the effects of combined application of nitrogen fertilizer, farmyard manure (fym), sewage sludge and municipal waste compost on nutrients concentrations of wheat flour (triticum aestivum cv. alvand) were studied in a randomized complete blocks design with 15 treatments and three replicates in agricultural research ...

introduction: mycorrhizal symbiosis is one of the most popular and highest symbiotic relationship in plant kingdom. most plants (about 80% of vascular plant species) have at least one type of mycorrhiza. arbuscular mycorrhizal fungies are the most important endomycorhiza fungi that play an important role in agriculture. materials and methods: in order to evaluate the effect of arbuscular mycorr...

Grazing management is a key element determining herbage production and grazing efficiency. This study measured herbage accumulation and grazing efficiency in Mombaça grass pastures (Panicum maximum cv. Mombaça) subjected to intermittent defoliation managements. Treatments were combinations of 2 rest periods (grazing at either 95 or 100% canopy light interception — LI) and 2 grazing intensities ...
