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...

In order to investigate the influence of bio- and chemical fertilizers on growth parameters and essential oil of fennel (Foeniculum vulgare Miller.), an experiment based on randomized complete blocks design with five treatments and three replications was carried out. Arbuscular mycorrhizal fungi (strain Sebacina vermifera) and phosphate dissolving bacteria (genera Peseudomonas) were applied as ...

BOWERS, G. R., Jr., and R. M. GOODMAN. 1979. Soybean mosaic virus: Infection of soybean seed parts and seed transmission. Phytopathology 69: 569-572. The presence of soybean mosaic virus (SMV) (Illinois severe isolate) in cotyledons, and embryos from immature seeds of both Midwest and Merit. reproductive plant parts was compared in field-grown, manually inoculated In mature seeds, infectious vi...

use of plant growth promoting bacteria (pgpb) and high quality of seed as agricultural inputs play important roles in sustainable crop production. to study the effects of different levels of seed aging and pgpb's application on field emergence, seedling establishment and yield of two red kidney bean cultivars in field conditions, an experiment was carried out as factorial based in a rcbd d...

this experiment was carried out to evaluate the effect of rhizobium strains and plant growth promoting rhizobacteria (pgpr) on dry matter partitioning and some growth parameters of chickpea (cicer arietinum l.) arman cultivar. this research was conducted as split plot based on complete random block design at zanjan university research farm. irrigation levels (optimum irrigation during season gr...

to investigate the effects of mycorrhizal fungi, phosphatic biofertilizer and manure application on yield and quantitative and qualitative criteria of coriander an experiment was conducted at khoramabad during growing season of 2013. the experiment design was applied as factorial layout based on a randomized complete block design with 18 treatments and three replications. the factors were mycor...

in order to study of nitrogen application time and seed inoculation with plant growth promotingrhizobacteria on yield, fertilizer use efficiency and grain filling rate of sunflower, a factorial experimentwas conducted based on randomized complete block design with three replications in research farm ofislamic azad university, ardabil branch in 2011. the first factor was time of nitrogen applica...

This study evaluated the symbiotic effectiveness and economic evaluation of Rhizobium inoculants with the objective of recommending the most effective inoculant strain for soybean and cowpea production in Northern Ghana. Field experiments were established in three locations using randomized complete block design with five blocks. A total of four treatments (Legumefix, Biofix, 100 kg N ha-1 and ...

effect of free and symbiotic nitrogen fixing bacteria on seed and seedling produced seeds under deficit irrigation was conducted in laboratory and field experiments in 2006. in laboratory of karaj’s seed and plant research and certificate institute an experiment was conducted based on factorial in form of completely randomized design with four replications and in field’s of islamic azad univers...
