abstract in order to study the effect of density and time of nitrogen application on morphological, phenological characteristics, yield and yield components of black cumin (nigella sativa l) a field experiment was conducted at chenaran in khorasan razavi province in 2005 growing season. three nitrogen fertilizer (urea) application times (1- control 2- at 4-6 leaves stage 3-preblooming 4-complet...

This study aims to evaluate the efficacy of nitrogen (N) forms: ammonium, nitrate, and urea on maize performance, N uptake use efficiency, grain protein content. The experiment was laid out as a split-plot with whole plot factor being three fertilizer treatments subplot four levels (0, 25, 50, 100 kg ha?1) replicates. Plant tissues were analyzed for total uptake. Grain stover yields determined ...

background and objectives: soybean is one of the plants that need large amounts of nitrogen for grain yield production. todays bio-fertilizers are considered as a best replacement for chemical nitrogen to increase soil fertility and sustained agricultural production. meanwhile, the use of soybean symbiotic bacteria and nitroxin, which contain the most effective nitrogen-fixing bacteria of the g...

We present a system called AESOP that automatically produces affect states associated with characters in a story. This research represents a first step toward the automatic generation of plot unit structures from text. AESOP incorporates several existing sentiment analysis tools and lexicons to evaluate the effectiveness of current sentiment technology on this task. AESOP also includes two nove...

persian shallot (allium altissimum regel.) is one of the perennial medicinal and industrial plant which is naturally growing in high elevated lands. in order to evaluate the effects of different nutrient elements such as nitrogen, phosphorus and potassium on photosynthetic rate and pigment content of persian shallot; an experiment was conducted as factorial based on completely randomized design...
