This study was carried out to evaluate the effects of four nitrogen treatments (50, 100, 150 and 200 Kg urea / ha) on biomass, crude protein, soluble carbohydrates and crude fiber contents in three fodders (corn, sweet sorghum and sweet sorghum bagasse) at the filed experimental station. The results showed the effects of nitrogen treatments and fodders on the above measurements were significant...

in many crops, incorrect management of nitrogen and water is one of the most important factors in the resources productivity such as water and nitrogen. in order to evaluate the effects of different nitrogen levels (zero, 50, 100 and 150 kg ha-1) and irrigation application rates (100, 75 and 50% of water requirement per species) on corn, sesame and sugar beet, three separate experiments was con...

introduction multiple cropping such as intercropping plays an important role in agriculture because of maximizing beneficial interactions. intercropping of legumes and cereals is an old practice in tropical agriculture that dates back to ancient civilization. maize-legume intercrops could substantially increase forage quantity and quality and decrease requirement for protein supplements (ahmad ...

in order to study the competition effects of redroot pigweed (amaranthus retroflexus) and millet (panicum miliaceum) on maize performance under different rates of n fertilizer, a field experiment was conducted in 2009 in the research fields of tarbiat modares university in tehran as a randomized complete block design with factorial arrangement of treatments and three replications. accordingly, ...

Objective: This field experiment was laid out in order to study on effect of Nano and Bio fertilizers on yield and yield components of tomato (Lycopersicone sculentum L.) during the growing seasons 2013- 2014. Methods: The experiment was laid out in a factorial based on randomized block design with three replications. Treatments were K nanofertilizer in five levels such as (0, 100, 200...

nitrogen is one of the most limiting nutrients for cereal production in many parts of iran. the effects of crop residue incorporation [0 (control), 25 and 50% of wheat (triticum aestivum l.)] and nitrogen (n) levels (0, 150, and 300 kg ha-1) on corn (zea mays l.) grain yield and nitrogen use efficiency were investigated at agricultural research station, shiraz university, shiraz, iran for two y...

A 3- years (2015, 2016 and 2017) field study was carried out at National Wheat Research Program, Bhirahawa, Rupandehi, Nepal to evaluate the influence of crop residues and nitrogen levels on rice. The experiment was conducted in split plot design with three replications. Main plots were two crop residue levels (with crop residues of 30 cm wheat stubble and without crop residues) and sub plots c...
