in order to study the effect of biological and chemical fertilizers of nitrogen and phosphorus on some physiological, morphological and phenological traits of sunflower this study was carried out in eivanegharb (ilam province) in summer of 2011. treatments were arranged in split factorial based on rcbd with three replications. the main plot include 4 levels of phosphorus and nitrogen chemical f...

Cowpea (Vigna unguiculata) is a major source of dietary protein and essential component of the cropping systems in semi-arid regions of Sub-Saharan Africa. However, yields are very low due to lack of improved cultivars, poor management practices, and limited inputs use. The objectives of this study were to assess the effects of rhizobia inoculant and P on nodulation, N accumulation and yield of...

to evaluate the effect of bio-fertilizers on physiological traits in soybean under water deficit condition, agreenhouse experiment was conducted in 2011, at faculty of agriculture, tarbiat modares university,using a factorial design based on rcbd with three replications. the experimental treatments weredifferent irrigation regimes including non-stress (40% water depletion), moderate stress (60%...

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...

The fungal entomopathogen Beauveria bassiana became established as an endophyte in in vitro-grown cocoa seedlings tested for up to 2 mo after inoculation to the radicle with B. bassiana suspensions. The fungus was recovered in culture from stems, leaves and roots. B. bassiana also was detected as an epiphyte 1 and 2 mo postinoculation. Penicillium oxalicum and five bacterial morphospecies also ...

The main objectives of the current study were to investigate effect arbuscular mycorrhizal fungi (AMF) and nano-iron chelate fertilizer under water deficit conditions on grain yield, root colonization, leaf chlorophyll concentration, oil percentage, fatty acid profile Lallemantia species. experiment was carried out as a factorial based complete randomized block design consisting three factors i...
