Abstract Cultivation of irrigated desert soils in Central Iran is one way utilizing under‐exploited land to produce more food. This study explores the value soil quality indicators as measures when converting croplands. Soil samples from unfarmed desert, wheat and alfalfa sites Abarkooh Plain (Central Iran) were taken 0–10, 10–20 20–30 cm depths. including organic carbon, total nitrogen, carbohydrate, particulate carbon (POC) aggregate fractions, water‐stability determined. The contained...

This study explores the effect of drought stress and ozone on cucumber. A factorial experiment with complete randomized design was carried out in a greenhouse. Experimental treatments were stress, including three levels 100% (control), 80%, 60% field capacity (FC) concentrations 0, 0.5, 1 ppm. The (80% FC) significantly reduced fruit length, weight, yield, leaf area, number fruits. Across statistical analysis showed significant increments weight increasing concentrations. An enhancement...

In this study, the concentrations of heavy metal (Cd, Pb, Fe, and Ni) in contaminated soils adjacent to two steel mill companies three crops (i.e., wheat, rice, onion) grown these regions were compared with a non-industrial site Isfahan province, central Iran. The results manifold. both soil within industrial turned out be more significant than nonindustrial counterpart. addition, surrounding demonstrated by Cd, Ni according limits provided international standards USEPA European Union...

This study was planned to investigate the concentrations of heavy metal in soils and crops estimate potential health risks metals humans via consumption grown at industrial sites (Zarrinshahr Mobarakeh) control site (Natanz) Isfahan province, central Iran. The food (wheat rice grains onion bulbs) were digested by acid digestion method then analyzed for Mn, Cu Zn atomic absorption spectrophotometer. results showed that concentration Mobarakeh higher than Zarrinshahr Natanz. Mn Natanz...

A greenhouse experiment was conducted to investigate the effects of salt stress and ozone on yield components cucumber. The treatments were defined by a two-factorial design three irrigation water salinity levels (2, 4 6 dS/m) concentrations (0, 0.5 1 ppm). After germination, cucumber seeds grown in pots containing soil, coco peat perlite fed with Hoagland's solution imposed treatments. results showed that significantly reduced fruit owing decrease both number weight. Also, statistical...

Salinity is one of the most progressive environmental factors limiting productivity crop plants.To evaluate effects foliar application amino acid on fruit yield, some elements and proline tomato under salinity stress, a greenhouse experiment were conducted in factorial arrangement based completely randomized design with three replicates.Five levels irrigation water including 2, 4, 6, 8 10 dS mG 1 3 (0, 2 4 g LG ) by method was used.Although, results indicated that significantly reduced yield...

This study was conducted to survey the levels of cadmium (Cd) and lead (Pb) in main foods Isfahan province (central Iran). The rice grains wheat breads were collected from city villages around Mobarakeh Steel companies. food samples wet-ashed by heating presence concentrated nitric acid hydrogen peroxide. concentrations Cd Pb determined inductively coupled plasma-optical emission spectrometer (ICP-OES). potential exposure risks then estimated. Levels investigated (except Sangak beard) above...

The main objective of this work was to evaluate the effects saline irrigation water and leaching on sugar beet yield components. In a field experiment in Rudasht region (Isfahan, Iran), three salinity levels (1.6, 8.1, 12.3 dS m−1) with/without were applied. experimental units comprised completely randomized block design, with split plot four replications. results indicated that white alkalinity decreased by increasing salinity. Salts significantly increased root yield, concentration. With...

Wind erosion is a widespread phenomenon causing land degradation in arid regions.The capacity of nanoclay soil control has been assessed wind tunnel experiments as novel technology.To study the effect on stability sandy soils against erosion, laboratory research program was set up tunnel.The samples were treated with distilled water and at rate 2000 ppm uniformly spread surface.The treatments performed condition velocity 31.0,55.2 67.3 km hG 1 .The results showed that volumetric content 300...

Wind erosion is one of the major causes sandy desertification in arid regions.Wind considered to be main process land degradation, crop damage and sedimentation.In this study, wind tunnel experiments were conducted investigate effect nanoclay at three different application rates on soil control.The isolated from soils was dominant montmorillonite clay.A loam applied, which Segzi, Isfahan.The area are structurally unstable these highly erodible for most seasons.The samples treated with...

A greenhouse experiment was carried out to investigate the effects of different growing media on some properties tomato (Lycopersicom esculentum L. cv. Falcato). Four including wheat residue, composted coco peat + perlite, and soil were applied in pot with completely randomized design three replications. The results showed that fruit yield, chlorophyll, vitamin C contents tomatoes grown residue perlite treatments significantly greater than other growth media. Fresh weight root inflorescence...

Sewage sludge application on agricultural land as an organic fertilizer the recycling of valuable components such many plant nutrients.Sewage is rich in macro and micronutrients.However, high concentrations heavy metals may cause pollution soil, groundwater human food chain because toxic metal uptake by crops.The objective this research was to investigate effect sewage concentration iron manganese parsley.This study were carried out a factorial experiment completely randomized design with...

A greenhouse experiment was conducted to investigate the effects of different culture media on plantlet emergence, vegetative and generative traits Marigold (Calendula officinalis) in randomized complete block design with ten treatments three replications. The were consisted spent mushroom compost (SMC), alluvium soil (AS), garden (GS), SMC + AS (2:1), GS (1:2), (2:1) (1:1:1). results showed that application had positive vase life flower number days from first bloom appearance. highest (17.4...

In order to investigate the effect of drought stress and ozone on some properties cucumber, a factorial experiment with complete randomized design was carried out in greenhouse at Khorasgan University, Isfahan, Iran 2014.Experimental treatments were including three levels 100% (control), 80% (mild stress) 60% field capacity (severe concentrations irrigation water (0, 0.5 1 ppm).After germination, cucumber seeds grown pots containing soil, cocopeat perlite fed Hoagland solution imposed...

Carbohydrates are an important component of soil organic matter, and a method is needed to quantify them, which would be efficient in terms time cost. Different extractants methods were examined this work for their efficiency extract carbohydrate C from four calcareous soils. Four (distilled water, 0.5 M potassium sulfate (K2SO4), 0.25 sulfuric acid (H2SO4)) three incubation (shaking 16 h, heating oven (85 °C) water bath 2.5 h) compared. The results show that significantly more was extracted...
