in order to investigate the effects of fertilizer types and irrigation regimes on quantitative criteria of three medicinal plants: lavander, rosemary and hyssop, an experiment was conducted at research field of faculty of agriculture, ferdowsi university of mashhad, during two growing years of 2007-2010. a split-split plot design with three replications was used. treatments were three irrigatio...
It is believed that various types of field bean, including pinto, white and red, differ in adaptability to high temperatures and may, thus, differ in response to delay in planting. In order to evaluate this response, an experiment was conducted during 1996 at the Agricultural Research Station, Isfahan University of Technology, using a randomized complete block design with split-plot layout. Mai...
Wheat (Triticum aestivum L.) was planted as winter crop using raised bed and conventional planting system with four N levels at Regional Wheat Research Station, Rajshahi (latitude 28°75′ N and longitude 92°58′ E), during November to March in 2002 and 2003 to study N content in grain and straw, uptake of total nitrogen, N use efficiency, fertilizer recovery percentage and grain yield. The highes...
To assess the effect of non chemical management of weed control on forage Sorghum (Sorghum bicolor) a field study was conducted in Varamin, Iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (W1= one time cultivation at 3-leaf stage using a duck foot cultivator, W2<...
Intercropping is one of the effective components of sustainable agriculture. In order to assess the effects of nitrogen application and planting arrangement on linseed and berseem clover leaf area, light absorption and their yield an experiment was conducted as a split plot based on randomized complete block design with three replications at the Research Farm of College of Agriculture, Isfahan ...
In order to investigate the effect of nitrogen (N) fertilizer and transplanting date (TD) on yield, yield components and stem lodging of rice (Oryza sativa), a two-year study (2007-2008) was carried out in Fozveh Research Station, Agricultural and Natural Resources Research Center of Isfahan, Iran, using split plots, based on randomized complete blocks design with three replications. Four N fe...

A field study was conducted in the boro season of 2011-12 and aman season of 2012 at Jessore, Bangladesh, to evaluate the performance of sequential applications of preemergence herbicides (oxadiargyl 80 g ai ha(-1), pendimethalin 850 g ai ha(-1), acetachlor + bensulfuranmethyl 240 g ai ha(-1), and pyrazosulfuron 15 g ai ha(-1)) followed by a postemergence herbicide (ethoxysulfuron 18 g ai ha(-1...
The effect of N levels and planting densities on quantitative and qualitative characteristics of grain yield in grain sorghum (cv. Kimia) was studied in summer 1998 at Kushkak Agricultural Research Station, Shiraz University. The experiment was a spilt plot with 4 replications in which 4 levels of planting densities (7.7, 10, 15.4, 20 seeds m-2) were applied as main plots and 4 levels of N (0, ...
this research was conducted at torogh agricultural research station in khorasan-e razavi province to determine the impact of irrigation cutoff at different growth stages and percentage of water use on the yield and water use efficiency (wue) of wheat cultivars using sprinkler irrigation. the study was done from 2006-2008. the experimental design was a randomized complete block design with a str...
