in this research, the effects of split application of nitrogen fertilizer on yield and yield component of three varieties of corn have been investigated. for this purpose, a split plot experiment on the base of randomized complete blocks in four replications was used. the main plots were three varieties of corn (370, 447 and 499), and sub plots were six split application of urea fertilizer trea...

in order to study the effect of chemical and biological fertilizers on silage corn under different plant densities, a split plot experiment was carried out in a randomized completely block design with three replicates in south western iran. the main plot included nitrogen fertilizer treatment at three levels (n1: with out chemical and organic fertilizers, n2: 75% chemical fertilizer + 100% orga...

Changes in the human gastrointestinal microbiome are associated with several diseases. To infer causality, experiments in representative models are essential, but widely used animal models exhibit limitations. Here we present a modular, microfluidics-based model (HuMiX, human-microbial crosstalk), which allows co-culture of human and microbial cells under conditions representative of the gastro...

the high yield depends on high dry matter production per unit area. azotobacter bio-fertilizer experiment to investigate the effect on the index, total dry matter accumulation and pishtaz and chamran wheat cultivars in 2005 was conducted in the faculty of agriculture, lorestan university. experiment, a split-plot randomized complete blocks design with four replicates were tested. treatments con...

BACKGROUND: Fertilizer management plays an important role for obtaining satisfactory yields and to increase crop productivity. Nitrogen is generally a limiting nutrient in crop production, and especially in sorghum, as it has been said to be the most responsive nutrient for its production. OBJECTIVES: Current study was conducted to assessment effect of urea fe...

Effects of organic manure (poultry manure) applied alone and integrated with inorganic fertilizer (urea) on yield and yield component, N-uptake and soil fertility in wheat-maize cropping system was evaluated in a field experiment at Nuclear Institute for Food and Agriculture, Peshawar, Pakistan. Poultry manure was applied alone and were integrated in different proportions with mineral nitrogeno...

BACKGROUND: Fertilizer management plays an important role to achieve sustainable agriculture. OBJECTIVES: Current study was conducted to assess response of agrophysiological traits of wheat to apply different level of fertilizer and biologic fertilizer (Phosphorus and Nitrogen). METHODS: This research was carried out via factorial e...

Microbial production and consumption of greenhouse gases (GHG) is influenced by temperature and nutrients, especially during the first few weeks after agricultural fertilization. The effect of fertilization on GHG fluxes should occur during and shortly after application, yet data indicating how application timing affects both GHG fluxes and crop yields during a growing season are lacking. We de...
