A protectant fungicide (Captan, a.i. captan) and a systemic fungicide (Switch, a.i. fludioxonilþ cyprodinil) were evaluated as preand post-inoculation applications for control of anthracnose fruit rot (AFR), caused by Colletotrichum acutatum, under a short (6 or 8 h) or long (18 or 24 h) wetting period. Evaluations were conducted for two seasons in Maryland and for two seasons in Florida. Both ...
The effect of potash biofertilizer and chemical fertilizer was studied on quantitative and qualitative traits of periwinkle in a factorial experiment based on a Randomized Complete Design with three replications, 48 experimental units, and two factors: (1) different methods of potash bio-fertilizer application at four levels of control (B0), seed inoculation (B1), root inoculation (B2) and seed...
In the present study, three chromium resistant bacterial strains (CrT-1, CrT-2, CrT-3) which could resist veryhigh concentration of K2CrO4 (up to 40 mg ml-1 on nutrient agar plates and 10 mg ml-1 in acetate-minimalmedium) were used to inoculate the sunflower seeds both as control and under chromium stress. Cr(VI)caused severe reduction in different growth parameters (seedling ...
Potassium is the most abundant nutrition element in the surface soil but most of the potassium is unavailable to the plants. The present study was conducted with the aim of isolation of potassium solubilizing bacteria from rhizosphere soil and evaluation of quantitative ability of released potassium from different sources of silicate by strains. For this propose, laboratory and greenhouse evalu...
A field experiment was conducted during the kharif season of 2014 at Crop Research Farm, Department Agronomy, SHIATS, Allahabad, UP to evaluate influence different sources phosphorus on productivity and profitability Greengram. The in randomized block design with 9 treatments viz. Control (No Phosphorus, 100% P through SSP, URP, 50% SSP + 75% 25% PSB inoculation, URP inoculation. greengram vari...
بررسی اکولوژیکی ازتوباکتر در دو منطقه مرتعی آذربایجان و اثر تلقیح آن روی رشد و تغذیه معدنی گیاه گندم
A great number of studies have been conducted on the role of Azotobacter - a free living N2-fixer - in agricultural soils, but our information is lacking on the importance of Azotobacter in pasture soils. This research was conducted to study the relationship between ecological and edaphical factors with the population of the bacteria in soil. Soil samples were taken from two sites in Azarbaidja...
In a field experiment conducted in a Mediterranean area of inner Sicily, durum wheat was inoculated with plant growth-promoting rhizobacteria (PGPR), with arbuscular mycorrhizal fungi (AMF), or with both to evaluate their effects on nutrient uptake, plant growth, and the expression of key transporter genes involved in nitrogen (N) and phosphorus (P) uptake. These biotic associations were studie...
Objective: The inoculation of substrates with arbuscular mycorrhizal fungi (AMF) is one of the most important effective strategies applied and one of the aims of sustainable agriculture. Methods: This experiment was conducted to evaluate the effects of AMF inoculation (0, 2.5, and 5 W/W) on morpho-physiological traits such as flower and root dry weight, water-use efficiency and antioxidant capa...
abstract large-scale mortality of in vitro raisedplantlets occurred during acclimatization, i.e. glasshouse hardening, and later at field transfer still has remained as a significant bottleneck in micropropagation. the usefulness potential of some arbuscular mycorrhizal fungi (amf) to minimize mortality rate of three commercial grape rootstock genotypes during glasshouse acclimatization was stu...
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...
