In acid soils, Al toxicity and nutrient deficiencies are main constraints for low yield of cacao (Theobroma cacao L.). A controlled growth chamber experiment was conducted to evaluate the effect of three Al saturations (0.2, 19, and 26%) adjusted by addition of dolomitic lime on growth and nutrient uptake parameters of cacao. Overall, increasing soil Al saturation decreased shoot and root dry w...

A commercially available microbial inoculant (Plant Growth Activator Plus) that contains 50 microorganisms, primarily bacteria, was evaluated in a soilless container substrate to determine its effects on root bacterial populations and growth response of container-grown plants at three fertilizer rates. The tropical ornamental plants included hibiscus (Hibiscus rosa-sinensis ‘Double Red’), spath...

in order to study impacts of organic manure levels and inoculation with mycorrhiza fungi on growth, quantitative and qualitative yield of hyssop (hyssopus officinalis l.), a field experiment was conducted as factorial based on a randomized complete block design with three replications at the agricultural research station, ferdowsi university of mashhad, during two growing seasons of 2009-2010 a...

Interactions between herbicides and vesicular-arbuscular mycorrhizal (VAM) fungi are little-known but may differentially affect the development of tolerant and susceptible plants. We conducted this greenhouse study to determine if VAM fungi modify the effects of the herbicide bentazon (3isopropyllH-2 ,1 ,3-benzothid iaz in(4)3H-one 2,2-dioxide) on soybean (Glyc ine max (L.) Merr.) and common co...

Pyrethrum is a perennial daisy grown commercially for the insecticide that is extracted from its flowers. In order to evaluate germination and seedling growth of pyrethrum under different temperature and drought stress treatments, an experiment was conducted in seed technology laboratory of Faculty of Agriculture of Islamic Azad University of Isfahan branch in 2018. During this experiment, poly...

allelopathic relationship between plant associations, could be applied in non-chemical ‎weed management, however, those allelochemicals should not have adverse effects on arable ‎crops. in order to evaluate allelopatic effects of barley (hordeum vulgare) on ‎germination & growth characteristics of lentil (lens esculenta), two experiments were ‎conducted based on compactly randomized design (crd...

in order to study, the effects of drought stress on germination and seedling growth of chickpea genotypes, experiments were carried out on two susceptible genotypes (mcc68, mcc448) and two resistant genotypes (mcc392, mcc877). in the first experiment the seeds were sown under different levels of drought stress (0,-0.4,-0.8,-1.2mpa) in 25◦c at the growth chamber with 4 replication. the results s...
