The present study assessed the effect of seed inoculation with single or multiple plant growth-promoting rhizobacterial (PGPR) strains on yield in spring wheat (Triticum aestivum spp. vulgare var. Kırık) and barley (Hordeum vulgare cv. Tokak) plants in both greenhouse and field conditions during the years 2007 and 2008. The treatments of wheat and barley plants during the first year include...

This work evaluated the effect of seed size and morphology on the development and biomass of durum wheat seedlings. Three different seed-grading sizes selected by sieving were used in glasshouse experiments, and a set of three developmental and 23 biomass-related indices were measured on eight genotypes, at two moisture levels. The influence of seed size on seedling development was studied at h...

Andrographis paniculata Nees is traditionally known as Kalmegh, Allelopathic effect of Kalmegh was examined on seed germination and seedling growth of four (Sonalika, VL-914, Euguanda-6 and Mond’s Aids) wheat genotype, the aqueous leaf extracts reduced seed germination and seedling growth of wheat. On the basis of value of per cent reduction in seed germination, germination relative index and v...

Agricultural sector area plays major role in Indian economy. This paper shows research comparison in between MLP Feed Forward Neural Network, Generalized Regression Neural Network and Radial-Basis Function Neural Network in the field of Wheat yield prediction using Z-score Normalization method. The outcome represents that GRNN present better prediction results as compared to FFNN and RBNN. Eigh...

in order to study the interaction allelopathic effects of wheat, barley and wild mustard on seed germination and seedling growth, this investigation was conducted in 2009 in two separate experiments. allelopathic effect of four aqueous extracts (0, 2.5, 5 and 10%) of wild mustard on wheat and barley germination was evaluated in the first experiment, based on two randomized completely designs (r...

Preventing the introduction of weeds into the farming system through sowing of clean seeds is an essential component of weed management. The weed seed contamination of cleaned grain and herbicide resistance levels of the recovered weed seeds were examined in a study conducted across 74 farms in the Western Australian grainbelt. Most farmers grew and conserved their own crop seed. The majority o...

drought stress is considered as one of the main important factors reducing field crop yield, thus leading researchers to study the related physiological characteristics may reduce drought effects. this experiment was conducted in research farm of seed and plant improvement institute (spii) in karadj, arak and jolgeh rokh for three cropping seasons (2008-2011) to evaluate drought tolerance of br...

An endophytic fungus found in Kentucky 31 (KY-31) tall fescue has been associated with the "summer syndrome" (fescue toxicity) in grazing cattle. Four experiments were conducted to investigate the use of weanling rats as an animal model to study the fescue toxicity syndrome. When graded levels of fungus-infected (INF) or fungus-free (FF) KY-31 seed were fed, feed intake and growth rates were in...

ABSTRACT-This experiment was carried out as factorial based on a randomized complete block design with three replications at the research station of the Islamic Azad University-Arak Branch, Iran, in 2011 and 2012. Experimental factors consisted of three levels of salicylic acid (SA); seed priming with distilled water (hydro priming), seed priming with 0.5 mM SA, and 0.5 mM SA  seed priming 1 mM...
