potassium (k) is an element essential for plant growth, playing a significant role in physiological and biochemical processes in plant. the relationship between a soil testing extractant vs. plant nutrient uptake should be a determining parameter in the selection of a soil testing method. the objective of this study was to evaluate different extractants employed for extracting available k in 10...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
Wheat (Triticum aestivum L.) was grown in earthen pots containing soil of Balkasar Soil Series (Sandy Loam) in green house at the Department of Soil Science and SWC, Pir Mehr Ali Shah Arid Agriculture University, Rawalpindi during Rabi season, 2007. The Crop was treated with two levels of Phosphorus (40 and 80 kg P ha-1 ) in the form of SSP, TSP, NP and DAP. A basal doze of 100 kg N and 60 kg K...

The influence of Nitrogen (N) rates on mineral nutrient uptake in stem and seeds, proline and carbohydrate in flag leaves of Wheat (Triticum aestivum L . Var Chamran) under saline conditions was studied in a field experiment in 2003 and 2004. The experiment was conducted using a split plot design with three replications. The treatments comprised five levels of salinity: 1.5, 5, 10, 15 and 20 ds...

Correlation between components of Q/I and wheat (Triticum aestivum L.) growth indices was studied in a greenhouse experiment during 2003-04 growing season. Eighty soil samples (0 – 30 cm depth) were collected randomly in farms around the Abyak region, Ghazvin province. Twenty-one samples were then selected based on soil texture and NH4OAC-K. The research included treatments of 21 soils and two ...
crop residues management is one of the most important factors to sustain agro-ecosystems. application of plant residues as organic fertilizers has functional role on the amount of soil elements, their availability for crops and finally yield obtained. in order to investigate the effect of different crop residues and their management on providing wheat potassium requirement, a four-replicated fi...
A field experiment was conducted to evaluate the interference effects of wild barley (Hordeum spontaneum L.) on wheat (Triticum aestivum L.) yield, in 2009. The effects of different densities of wild barley (0, 25, 50, 75, 100, 125 plants m-2) in interferences with wheat at density of 300 plants m-2 were studied in a completely block design with three replications. Results showed that with incr...
Cadmium is a toxic element in plant nutrition and is considered as a contaminant of food and feed. A greenhouse experiment was carried out to examine the effects of combined application of cadmium and zinc on responses of wheat on a clay loam soil texture. This experiment was designed in a factorial experiment with randomized complete block design (RCBD) and four replicates per treatment. Three...
