A pot experiment was carried out to determine the effect of foliage spraying of silicon (Si) on growth and ornamental characteristics of calendula grown under salt stress and greenhouse conditions. A factorial experiment based on completely randomized design was conducted with 3 levels of Si (0, 50 and 100 mg/l) and 3 levels of NaCl (0, 100 and 200 mM) with 4 replications. At flowering stage, S...

to investigate the effects of priming and foliar spray by 24-epibrassinolide (ebr) on some of marigold morphological, biological and biochemical traits, an experiment was conducted as factorial on completely randomized design with three replications at experimental laboratory of department of horticulture, shahid bahonar university of kerman in 2014. each of priming and foliar spray of ebr had ...

Results from an innovative approach to improve remediation in the rhizosphere by encouraging healthy plant growth and thus enhancing microbial activity are reported. The effect of arbuscular mycorrhizal fungi (Am) on remediation efficacy of wheat, mungbean and eggplant grown in soil spiked with polyaromatic hydrocarbons (PAH) was assessed in a pot experiment. The results of this study showed th...

The interaction of retention time in the rumen and concentrate diet on methane production in vitro and acetate:propionate ratio was examined. Twenty-four fistulated sheep were used in a complete factorial design with the sheep randomly divided into 4 groups. The sheep had a 5-wk acclimatization period on an oaten chaff diet, followed by two 3-wk diet phases. Two of the 4 groups were maintained ...

The endoparasitic nematophagous fungus Meria coniospora reduced root-knot nematode galling on tomatoes in greenhouse pot trials. The fungus was introduced to pots by addition of conidia at several inoculum levels directly to the soil or addition of nematodes infected with M. coniospora to the soil; both methods reduced root galling by root-knot nematodes. These studies represent a part of a rec...

Establishing forage legumes into endophyte-infected tall fescue (Festuca arundinacae Schreb.) pastures is problematic, especially in well-established stands. A oversowing field experiment determined if this problem was because of poor nodulation. Four renovation techniques, clipped sward (treatment A), herbicided + rye seeding in the previous autumn (treatment B), herbicided in the autumn and s...

biological methods based on using soil beneficial microorganisms’ potentials for creating symbiosis relationship with plants by modifying genetic structure of plants resulting in improving nutritional status and crops quality. this study was conducted in order to investigate the effect of piriformospora indica inoculation on root colonization and uptake and transportation of phosphorus, zinc an...

Background: Root-knot nematodes (Meloidogyne spp.) are the most devastating pests of vegetables, especially in tropic and subtropic regions. Meloidogyne incognita is among major pathogens found tomato crop causes a significant yield loss. This study evaluates resistance susceptible cultivar against root-knot incognita). Methods: A greenhouse was conducted to evaluate or susceptibility nine cult...

Pot experiment was conducted to study the alternate and fixed partial root zone drying on irrigation water use efficiency phosphorus absorption of corn (Zea mays L.) in a gypsiferous soil during spring growing season. The included three techniques, which were conventional (C1), alternating root-zone (APRD) (FPRD), levels phosphate fertilizer application (40, 80, 120 Kg h-1), for stages plant gr...

Rice has become a major staple cereal in sub-Saharan Africa. Currently, upland rice cultivation is expanding particularly in rainfed areas where the root parasitic weed Striga hermonthica, a major constraint to cereal production, is endemic. Laboratory, pot, and semi-controlled open air experiments were performed to evaluate resistance of selected rice varieties in Sudan to a resident S. hermon...
