introduction: in respect of underground cultivation, production and consumption wheat is the major alimentary seed in iran. the contamination of wheat to fungi especially aspergillus flavous (the most important aflatoxin producer in nature) and aflatoxin is a risky factor to community health. the aim of this study was to identify aspergillus flavous and aflatoxins in the stored wheat of mazanda...

this study evaluated direct drilling planters used for wheat cultivation in khorasan-e razavi province. a randomized complete block design with three replications was used. the treatments were direct drilling of wheat plants into wheat residue using the following direct planters: (1) sfoggia (13-25), (2) baldan (spd3000), (3) tondar (spd 2500), (4) semeato (shm 11/13). the parameters measured w...

this experiment was conducted using a randomized complete block design with three ‎replications with 10 barley cultivars in dryland research station of northern khorasan (shirvan) ‎in 2004-2005 growing season. results indicated that there was significant differences among the ‎lines in terms of the stand percentage, days to emergence, days to heading, days to maturity, plant ‎height, number of ...

the present study aimed at investigating the effect of different levels of nitrogen on yield and yield components of bread and durum wheat. to this end the experiment was conducted in 2010-2011 in south west of iran as split plots based on randomized complete block design with three replications. main plot included four levels of nitrogen 60, 120, 180, 240 kg.ha-1 and the sub plot included four...

We present a novel non-parametric method for finding a subspace of stimulus features that contains all information about the response of a system. Our method generalizes similar approaches to this problem such as spike triggered average, spike triggered covariance, or maximally informative dimensions. Instead of maximizing the mutual information between features and responses directly, we use i...

Neural adaptation underlies the ability of neurons to maximize encoded information over a wide dynamic range of input stimuli. Recent spiking neuron models like the adaptive Spike Response Model implement adaptation as additive fixed-size fast spike-triggered threshold dynamics and slow spike-triggered currents. Such adaptation accurately models neural spiking behavior over a limited dynamic in...

to determine the effect of n-fertilizer on nitrogen harvest index (nhi), crop production and growth indices of corn (s.c.704 cultivar), an experiment was conducted with five nitrogen rates (100, 140, 180, 220 and 260 kg n/ha) in a randomly complete block design in four replicates. the effect of n-fertilizer rates on variation of grain yield, number of kernels, 1000-kernel weight, nitrogen harve...

with increasing the world population, and needing to feed it, the yield enhancement of cereals crops is of the most important approaches meet this target, which is achieved via identifying the effective factors underlay yield of cereals like wheat. this experiment was conducted to evaluate the grain yield and its association with some contributed traits in a doubled-haploid (dh) wheat populatio...

a field study was conducted at the college of agriculture, shiraz university, shiraz, iran to evaluate the effect of different crop residue and nitrogen rates on yield and yield components of two dryland wheat (triticum aestivum l.) cultivars. the experiment was conducted as a strip split plot with four replications. vertical plots included two dryland current wheat cultivars (azar2 and nicknej...
