in order to investigation of waterlogging stress effects on morphological and physiological traits of rapeseed in different developmental stages, a pot experiment was conducted at gorgan university of agricultural sciences and natural resources during 2010-2011. the experiment design was completely randomized with factorial arrangement and three replications. examined factors were developmental...

Soil drying and rewetting may alter the release and availability of aged pesticide residues in soils. A laboratory experiment was conducted to evaluate the influence of soil drying and wetting on the release of pesticide residues. Soil containing environmentally long-term aged (9-17 years) (14) C-labeled residues of the herbicides ethidimuron (ETD) and methabenzthiazuron (MBT) and the fungicide...

effect of different amounts of sulfur fertilizer (0, 50, 100, 150, 200, 250 kg/ha) and 200 kg/ha of thiobacillus inoculant on yield, quality and storability of two edible onion cultivars red rey and white qom were investigated. the experiments were conducted at experimental field and laboratories of the department of horticulture, seed and plant improvement institute, karaj, iran in 2007-08 cro...

in order to study the effect of organic fertilizer on shoot yield and essential oil content of lavender, this experiment was conducted in the research institute of forest and rangelands, karaj, iran, in 2013-14. the treatment groups consisted of vermicompost (0, 5, 10 and 15 ton/ha) and cow manure (0, 10, 20 and 30 ton/ha). the experimental design was a factorial experiment based on randomized ...

to evaluate the effect of water, tape drip and furrow irrigation methods on the performance components and features of agria cultivar potato, an experiment was carried out in the agriculture faculty of kermanshah. repeated three times, this study was carried out in the form of full random blocks with the main factor of different amounts of irrigation water in three levels (50, 75, and100 percen...

abstract poultry manure contains considerable nutrients and its application to agricultural land may boost soil fertility. in order to study the effects of poultry manure and its incorporation method with soil on soil chemical properties, a field experiment was conducted at the ecological research center of zagroos, 30 kms from northeastern of khorramabad for two consecutive years (2004 and 200...

Post-anthesis drought affects wheat production worldwide, primarily through the limitation of grain filling. The enhanced remobilization stem reserves induced by can provide considerable carbon sources for aim this study, which was part an ongoing wheat-breeding program targeting tolerance, to assess ability 20 contrasting common genotypes (2 cultivars, 8 F6:7 families (FAM), and 10 parent (PAR...

In this trial effects of feeding pistachio by-product silage with date waste (PBSD) on dry matter intake (DMI), live weight gain and blood parameters of lambs were studied. Ensiling of pistachio by-products (PBP) with date waste increased dry matter (DM) and metabolizable energy (ME), but decreased the percentages of crude protein (CP), total tannins and phenolic compounds (P

in this study, the chemical composition of the tea wastes determined. the value of dry matter, organic matter, crude protein, crude fiber, calcium and phosphorous 95, 94, 13.3, 23.1, 0.011 and 0.29 percent, respectively. in the experiment of digestibility by animal, five experimental rations (including tea waste and alfalfa in the proportion of 0:100, 10:90, 20:80, 25:75 and 30:70 percent) and ...
