Due to climate change and declining water resources, some farmers are turning to wastewater. One of water pollutants is household detergent. To examine this, a study was conducted to determine the effect of water contaminated with hand washing liquid on the germination characteristics of wheat, flax, and lentil in a completely randomized design wit...

Drought is the major challenge of the present century in agricultural areas. Water scarcity has led to the use of contaminated water. The objective of the study was to determine the tolerance of wheat, Sirvan cultivar, to detergent contaminated water and drought at germination and early growth stages. The research included germination and pot exper...

Drought limits plants growth. In many parts of the world, crop productions depend on water availability. Seed germination is a sensitive and low water stage in plants. A pot experiment was designed to test the effect of dew-irrigation on seed germination percentage of fennel, flax, and fenugreek. Irrigation treatments included dew-irrigation and co...

Water shortage leads farmers to use sewages for irrigation. Sewages contain a large amount of laundry detergent. In this study the impact of irrigation by contaminated water on shoot biomass and seed germination of foxtail millet (Setaria italica) was investigated. The research was conducted as laboratory and pot experiments. Iso-potentials (− 0.04...

Irrigation is an increasingly important practice for sustainable agriculture. Water reuse as refined or non-refined wastewater can help agroecosystem productivity. Contaminated water may influence seed germination. Two experiments as laboratory and pot were carried out to assess impact of different levels of laundry detergent and water stress on se...

Response of pumpkin species including Cucurbita pepo convar. Pepo, Cucurbita moschata Duch, Cucurbita pepo, Cucurbita maxima, and Lagenaria vulgaris to bentazon, trifluralin, metribuzin, and oxyfluorfen was evaluated in Outdoor pot experiments in 2014 and 2015. Different postemergence doses (bentazon and oxyfluorfen) and preplant incorporated (metr...

Weeds are a serious threat to crop production in Iran as they reduce the yield of wheat, barley, rice, maize, and chickpea on average by 23%, 21%, 35%, 20%, and 50%, respectively. Orobanche spp., Avena ludoviciana (Durieu.), Convolvulus arvensis (L.), Sorghum halpence (L.) Pers, and Cuscuta compestris (Y.) are the most important weed species that c...

Foxtail millet is a short life cycle plant and known as a drought tolerant crop. Nowadays, contaminated wastewater with laundry detergent is used for irrigation. A pot experiment was conducted to evaluate the effect of contaminated water with laundry detergent on foxtail millet root and physiological traits. Contaminated water (concentration of 0,...

Myagrum perfoliatum is a noxious broad-leaved weed in western Iranian farming systems. A better understanding of the timing of seedling emergence would facilitate the development of better control strategies for this weed. Therefore, the objective of this study was to examine the effects of different factors on muskweed seed germination. Only 2.8%...

Two pot experiments were carried out to investigate effect of deficit irrigation with wastewater on seed yield, heavy metals and seedling emergence in oat (Avena sativa). The research at seedling stage included different ratios of sewage-contaminated water (100% well water, 75% well water + 25% wastewater, 50% well water + 50% wastewater, 25% well...

Irrigation is an increasingly important practice for sustainable agriculture. One of the sources for irrigation is sewage. Contaminated water may affect seed germination and plant growth. A laboratory experiment and a pot experiment were conducted in 2012 to determine the effect of different doses of laundry detergent and water stress on seed germi...

Defoliation can affect maize seed yield. In order to determine the effect of defoliation treatments on maize yield, yield components and produced seed germination traits, a field and a laboratory experiments were conducted in 2012. The field experiment included six defoliation treatments (D1= control, no leaf removal, D2 = defoliating tassel leaf,...

Two field experiments were conducted to evaluate the possibility of increasing diversity of winter cereals- based double cropping systems and their responses to deficit irrigation. In experiment 1, forage yield and quality of three corn hybrids, three sorghum cultivars and three species of millet (foxtail, common and pearl millet) were evaluated. B...

Field and laboratory experiments were conducted in 2011 to determine the effect of tassel removal and intensity of defoliation on yield of maize. The field experiment consisted of four defoliation treatments (D1= control, no leaf removal; D2= defoliation of leaves at the top of the ear; D3= defoliation of leaves under the ear; D4= defoliation of al...

One of the sources for irrigation is sewage. Contaminated water may affect seed germination and plant growth. A laboratory experiment and a pot experiment were conducted in 2012 to determine the effect of different doses of detergent on seed germination traits and early growth of sunflower (Helianthus annuus L.). The experiments included eight dose...

People are worried about effect of household cleaning products in the environment. One of the sources of detergent is sewage that is being used for irrigation of the crops. A laboratory experiment and a pot experiment were conducted in 2012 to determine the effect of irrigation with different doses of detergent on plant growth and seed germination...

A field experiment and a laboratory experiment were conducted in 2011 to determine the effect of intensity of defoliation on yield of maize (Zea mays). The field experiment included seven defoliation intensities (0, 2, 4, 6, 8, 10 and whole leaves per plant) from top to bottom leaves. Seeds of the field experiment were used for the laboratory exper...

Improper irrigation management is a major factor contributing to water shortage problem. A pot experiment was conducted in order to evaluate partial root zone drying and water use efficiency in root-divided foxtail millet. The study was conducted as a factorial experiment based on randomized complete block design (RCBD) with three replications. We...

Early and late cold stress in fall and spring, saline, drought and heat stress are also some important factors for decreasing percent and rate of germination in wheat. Osmotic priming increases the rate of germination and monotonousness of emergence and decrease undesirable effects of stress by changing on activity of some seed enzymes. In present...

A field and a laboratory experiments were conducted in 2008 to determine the effect of irrigation treatments on yield, yield components and seed germination of foxtail millet (Setaria italica). Conventional furrow irrigation (M1) and alternate furrow irrigation (M2) methods and different deficit irrigation levels including 100, 85, 70 and 55% of cr...
