The effect of draining crop fields during the wheat season on the soil CH4 andN2O emissions during the rice season in this article. There were four treatments:traditional cultivation during the wheat season + cultivation without fertilizationduring the rice season (CK1 field), traditional cultivation during the wheat season +traditional cultivation during the rice season (CK2 field), draining t...

two types of paddy combine harvester (head-feed and whole-crop) are commonly available in different widths in developed countries. the use of combine harvesters can greatly decrease labor costs and efficiency. combine harvesters have been introduced in several east asian countries (china, japan, south korea) to decrease costs, but their technical and economic performance has not yet been studie...

This paper presents the effect of electric field distribution which is an electric field intensity analysis. Consideration of the dielectric heating of grains and insects, the rice and rice weevils are utilized for dielectric heating analysis. Furthermore, this analysis compares the effect of electric field distribution in rice and rice weevil. In this simulation, two copper plates are used to ...

the main purpose of this research is to determine the effective factors in adopting biological control in the farmer field school approach. the method used in this research is descriptive-correlation and comparative, which has been done by survey. the rice farmers of the township of babol, mazandaran, iran were selected as the sample population of this research. the statistical sample of the re...

This study assessed the viability of using planted, mature rice fields in mitigating diazinon (an organophosphate insecticide) runoff toxicity using aqueous 48 h Hyalella azteca whole effluent toxicity bioassays. Rice fields decreased diazinon concentrations 80.1%-99.9% compared with 10.8% in the unvegetated field control. H. azteca survival responses coincided with observed diazinon concentrat...

An assessment of within field spatial variations in grain yield and methane (CH4) emission was conducted in lowland rice fields of Myanmar. Two successive rice fields (1(st) field and 2(nd) field) were divided into fertilized and non-fertilized parts and CH4 measurements were conducted at the inlet, middle and outlet positions of each field. The results showed that CH4 emissions at non-fertiliz...

Rice crop quality evaluation method through regressive analysis between nitrogen content in the rice leaves and near infrared reflectance measurement data from near field, from radio wave controlled helicopter is proposed. Rice quality dependency on nitrogen of chemical fertilizer and water supply condition is evaluated. Also homogeneity of the rice crop quality in the paddy fields is evaluated...
