Modern rice farms are characterized by the use of synthetic agrochemicals, which eliminate a large segment of biodiversity on-farm. In contrast, organic rice farms tend to preserve much of natural biodiversity. While biodiversityproductivity relationship in organic vs. chemicalised rice farms is contested, the relationship of on-farm biodiversity with food web structural properties and ecosyste...

abstract present study used translog cost function for determining break point of paddy farms. requested data set include inputs’ prices and quantities, and production amounts had been acquired from 500 rice farmers of guilan province at 2009. model used in this study is seemingly unrelated regressions (sur). the results showed that labor and pesticides had the highest and lowest share of produ...

state in the country with more than 1.5 million This study evaluates the economic suracres (USDA, Crop Production). vivability of rice farms in the Delta area of Since 1981, rice acreage in the Mississippi Mississippi. A general whole-farm simulation River Delta region, as in other rice-producing model, FLIPSIM V, is used to simulate the regions of the country, has generally declined. operation...

BACKGROUND Pyrethroid insecticides (PYR) are commonly used in rice farms and household pest control in Thailand. No investigative study has yet been made regarding factors associated with PYR exposure among Thai children. OBJECTIVE This study aimed to compare the levels of PYR exposure between children living in rice farms (high-intensity PYR used) and aquacultural areas (low-intensity PYR us...

abstract the production unit size is one of the effective factors in optimum uses of inputs. since optimum size is affected by the characters and economical conditions in each district, the studies for determining the optimum farm size should be done specially for each crop and each district. in this study tried to determine the optimum rice farm size in guilan province which is one of the most...

One of the reasons for the success of the agricultural sector in the developed countries is regulate the size of the farms, because it helps to scale economy of production. Considering that the size of agricultural production units should be specifically determined for each product and in each area, the aim of this study is to determine the optimum size of rice farms in the Fereydounkenar count...

The study was undertaken to examine the socio-economic profiles of women participated in farms and rice mills activities; to examine contribution of women to household income which reducing their poverty; to identify the factors influencing the level of family income in farms and rice mills labourers; and to identify the problems and constraints of farms and rice mills.

Extensive land and market reform in Vietnam has resulted in dramatic increases in rice output over the past thirty years. The land and market reforms in agriculture were pervasive, moving the system of rice production from commune-based public ownership and control to one with effective private property rights over land and farm assets, competitive domestic markets and individual decision makin...

In this study the environmental impact of consolidated rice farms (CF) - farms which have been integrated to increase the mechanization index - and traditional farms (TF) - small farms with lower mechanization index - in Guilan Province, Iran, were evaluated and compared using Life cycle assessment (LCA) methodology and adaptive neuro-fuzzy inference system (ANFIS). Foreground data were collect...

This paper employed the endogenous switching regression and propensity score matching methods to analyse the impact of row-planting technology on rice productivity using 470 rice farms in Northern Ghana. The empirical findings showed that the adoption of row-planting technology exerted greater positive impact on rice yields of smallholder farmers. In addition, rice yields of adopters and non-ad...
