to investigate the effects of drought stress and different combinations of animal manure with super absorbent polymer on yield and yield components of corn, a split plots design was conducted based on a randomized complete block design with 3 replications in fars agricultural research center in 2007. irrigation treatments were assigned as the main factor in three levels: 70, 105 and 140 mm evap...

A study of the aquatic fate of the triethylamine salt of triclopyr (3,5,6-trichloro-2pyridinyloxyacetic acid) was conducted in three bays of Lake Minnetonka, Minnesota. Triclopyr is under review by the US Environmental Protection Agency as a selective aquatic herbicide. The primary purpose of this study was to determine dissipation rates of the parent active ingredient, triclopyr, and its major...

Abstract While weed management is often thought of as an agricultural issue, weeds are also problematic for homeowners, public space managers and utilities. In these situations, typically hand‐pulled, mechanically treated or managed via herbicides. Hand pulling mechanical treatments labour‐intensive, all control methods may have unintended off‐target impacts, necessitating new alternatives cont...

in order to evaluate the effects of duck with azolla sp. on weed density and growth parameters in rice-duck farming system, an experiment was conducted at sari agricultural sciences and natural resources university during 2012. experiment was arranged in split plot based on randomized complete block design with three replicates. main plots were duck at four levels (control, 400, 800 and 1200 pi...

Gurdaspur borer causes great losses to sugarcane especially ratoon crop. On one way it damages the crop and on the other way its infestations paves way for certain diseases like red rot, stem rot and ratoon stunting disease. Experiments were conducted at Sugar Crops Research Institute, Mardan during 2003-2004 in sugarcane ratoon crops with the objective to see the effect of different control me...

On the one hand, commercial biometric systems and forensic identification require different approaches in order to evaluate system outputs. On the other hand, bayesian approach for evidence analysis and forensic reporting perfectly suits the needs of the court and the forensic scientist. Inside this bayesian framework, any biometric system can be adapted to provide its results in the form of li...

Damage caused by water shortages leads to physiological and biochemical changes in metabolism of plants and make them predispose to attack by pests and diseases and reduce the quality of the crops. In order to evaluate the effect of supplemental irrigation on safflower fly (A. helianthi) population of safflower cultivars, an experiment conducted as a split plot based on randomized complete bloc...

the erosion in dryland caused decrease in yield and soil quality, especially in slope land with conventional tillage. to investigate effect of tillage and planting methods in slope land on erosion and yield of dryland wheat, an experiment was conducted in 2007 at kermanshah province. the statistical design for this research was strip split plots in rcb (randomized complete blocks) with three re...
