Faruq Hasan M. 2008. Economic Efficiency and Constraints of Maize Production in the Northern Region of Bangladesh. j. innov.dev.strategy 1(1): 18-32 The study was conducted at the Sadar upazila of Dinajpur and Panchagarh to estimate the costs, returns and economic efficiency of maize production compared to Boro rice. The growth rate of maize in the country and constraints to maize production at...

abstract striped rice stem borer, chilo suppressalis walker (lepidoptera: pyralidae) is one of the important pests in rice fields of mazandaran. therefore, almost the farmers of northern iran apply several pesticides in nurseries for the pest control; while it is causes environmental risks and damages to human. in this research two different items including, 1- study of egg masses density in nu...

Abstract There is a decrease in cultivated area and production of rice Iraq. This study was conducted Mahanawiyah District, Diwaniyah Province, Iraq, to identify constraints facing farmers. One hundred thirty farmers were randomly selected. A list 3 categories affecting cultivation: production, financial institutional, covering 25 prepared administered the respondents.50% indicated there high l...

Spatial patterning often occurs in ecosystems as a result of a self-organizing process caused by feedback between organisms and the physical environment. Here, we show that the spatial patterns observable in centuries-old Balinese rice terraces are also created by feedback between farmers' decisions and the ecology of the paddies, which triggers a transition from local to global-scale control o...

A study was conducted to determine the magnitude of area shifting to different crops over the years, assess the profitability of maize cultivation and to evaluate the factors determining area devotion to maize cultivation in Bangladesh. Sample survey was done in five districts capturing both favourable and drought prone production environment. Two villages under each district were chosen in con...

A comprehensive assessment of drought environmental and socio-economic impacts provides critical information to rational decisions supporting drought mitigation policies and programs. The objectives of this study were to survey environmental and socio-economic impacts of drought in Guilan Province, and prioritize them from the viewpoint of paddy farmers. This study was a descriptive-correlation...

The main aim of this paper is to propose a state of art wireless sensor technology in agriculture, which can show the path to the rural farming community to replace some of the traditional techniques. In this project, the sensor motes have several external sensors namely leaf wetness, soil moisture, soil pH, atmospheric pressure sensors attached to it. Based on the value of soil moisture sensor...

Human niche construction encompasses both purely biological phenomena, such as the evolution of lactose tolerance, and dual inheritance theory, which investigates the transmission of cultural information. But does niche construction help to explain phenomena in which conscious intention also plays a role? The creation of the engineered landscape of Balinese rice terraces offers a test case. Pop...
