in order to investigate the yield and quality of forage in intercropping barley and fennel, an experiment was carried out as split plot based on a randomized complete block design with three replications at the research farm of agriculture and natural resources of ramin university during growing season of 2012-2013. four treatments levels of nitrogen including: (0, 70, 140 and 210 kgn.ha-1) hav...

to evaluate the yield and quality of barley (hordeum vulgare)–vetch (vicia desycarpa) intercropping, a series of experiments were conducted at the experimental field of the college of agriculture, university of tehran, in karaj (iran) from 2003 to 2005. the ex-periments were arranged in a randomized complete block with a split plot design and four replications. three levels (0, 45 and 90 kg n h...

Data-driven metric adaptation is proposed for proteome analysis of 2D-gel electrophoretic plots aiming at identification of stress related proteins in two barley cultivars with different response towards different salt stress conditions. Gradient descent is applied to the ratio of intraand inter-class distance sums to optimize the matrix parameters of generalized Mahalanobis distances in order ...

Because of continuing increases in atmospheric CO2, identifying cultivars of crops with larger yield increases at elevated CO2 may provide an avenue to increase crop yield potential in future climates. Free-air CO2 enrichment (FACE) systems have most often been used with multiple replications of each CO2 treatment in order to increase confidence in the effect of elevated CO2. For screening of c...

Morphological characters of soybean can be influenced by shading which are occasionally caused in plants. Thus, this study aimed to evaluate the effect different levels on epicotyl length, diameter and height The experiments were conducted a greenhouse. When plants reached V2 development stage, measurements taken length experiment I (conducted autumn); diameter, plant II (spring/summer) III (su...

Reasons for the variable amylose content of endosperm starch from waxy cultivars of barley (Hordeum vulgare) were investigated. The mature grains of most such cultivars contain some amylose, although amounts are much lower than in wild-type cultivars. In these low-amylose cultivars, amylose synthesis starts relatively late in grain development. Starch granules in the outer cell layers of the en...

a field experiment was conducted during 2003-4, 2004-5 cropping seasons evalute the effects of plant density on growth and yield of different rapeseed cultivars. the study was carried out at ramin agriculture and natural resources university (35 km from northeast of ahwaz). the experiment was in the form of split plots' based upon a complete randomized block design of four replications. ma...

greenbug isolate avirulent to Wintermalt. Subsequent work by Ogecha et al. (1992) confirmed that biotype G Most biotypes of the greenbug [Schizaphis graminum (Rondani)] was less successful in feeding on Wintermalt compared are extremely damaging to barley (Hordeum vulgare L.). However, with other biotypes. When compared with biotypes E greenbug biotype G has been reported to be unable to succes...
