Iron (Fe) and zinc (Zn) deficiency has been known as a key factor in limiting crop production in calcareous soils of arid and semi-arid regions. Since the components of organic matter can change Fe and Zn availability, this study was conducted to investigate the effects of humic treatments including humic acid (HA), fulvic acid (FA), vermicompost (Verm), HA+FA and HA+FA+Verm and mycorhiza inocu...
Humic substances (HS) reportedly enhance moisture retention of soil. However, no information is available as to the effects of HS on sand-based golf course putting greens. HS have acidic functional groups (COOH) that are reaction sites on the molecule. An greenhouse experiment was conducted to evaluate the effect that the acidic functional groups in humic acid, tannic acid and citric acid have ...
In order to increase the quality of agricultural products and improve healthy food production systems, application of organic fertilizers has become very important in agroecosystems. To investigate the effect of different concentrations and time of humic acid foliar application on the qualitative characteristics and shoot and grain micronutrients content of Triticale, an experiment was conducte...
بررسی ارزش غذایی تاغ و عمل آوری آن با سود و آهک در مراحل مختلف رشدبا استفاده از روش کیسه های نایلونی
abstract this study is carried out to determine the chemical composition in the three vegetative stages of the haloxylon sp., degradation parameters, with adding naoh and ca(oh2 ). for this purpose, in may and october and january 2010 enough some haloxylon sp. of the ammary area was prepared. crude protein and ash percentage are decrease, neutral detergent fiber percentage with pragress stage ...
To investigate the effects of humic acid and mycorrhiza fungi on visual quality, some characteristics of roots and chlorophyll changes of ryegrass, an experiment was carried out in Research Greenhouses of Department of Horticultural Science, University of Tehran, in spring and summer of 2009. The ryegrass was “Speedy green” perennial ryegrass, which is composed of three lolium (Lolium perenne L...
to survey the effects of nutritional and growth regulator components on adverse effects of recent consecutive droughts, an experiment was conducted on uniform grape trees (vitisviniferal.clv.'khalili') in bavanat and shiraz (akbar-abad) regions in 2010- 2011.trial was arranged in a randomized complete blockdesign (rcbd), with three replication and five trees per each plot. experimental treatmen...
abstract to assay the effect of acetylsalicylic acid pretreatment on enhancement of yield and yield components of barley (reihan-03) under water stress condition, an experiment was conducted as a spilt-plot arrangement based on randomized complete block design with four replications at the research field of shahid bahonar university of kerman, iran, in 2012-2013. irrigation condition was arrang...
silicon is known to ameliorate the deleterious effects of drought on plant growth. we evaluated growth of wheat (triticum aestivum l. cv. chamran) under water-deficit stress induced by polyethylene glycol as affected by si application. in this article, the effects of si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (rwc), electrol...
Soil salinity is a serious environmental problem that has negative impacts on growth and production of plants. On the other hand, application of chitosan has recently been increased to enhance the resistance to different stresses, such as salinity. In order to study the effect of chitosan seed-priming on alleviation of salinity stress in fenugreek (Trigonella foenum-graecum L.) a factorial expe...
nitric oxide (no) is a bioactive molecule, which was found to have several physiological roles, including antioxidant. to have a better understanding of the effects of no concentrations (0, 0.1 and 0.2 mm) on germination, growth, photosynthetic pigments, lipid peroxidation and antioxidant activity of basil (ocimum basilicum l.) under different salinity concentrations (0, 100 and 200 mm of nacl)...
