News Update on Rice Farmers Research: May – 2019

Profit efficiency among Bangladeshi rice farmers

Production unskillfulness is sometimes analyzed by its 3 components—technical, allocative, and scale potency. during this study, we offer an on the spot live of production potency of the Bangladeshi rice farmers employing a random profit frontier and unskillfulness effects model. The data, that are for 1996, embrace seven typical inputs and several other other background factors moving production of contemporary or high yielding varieties (HYVs) of rice unfold across twenty one villages in 3 agro-ecological regions of People’s Republic of Bangladesh. The results show that there are high levels of unskillfulness in fashionable rice cultivation. The mean level of profit potency is seventy seven suggesting that associate calculable twenty three of the profit is lost because of a mixture of technical, allocative and scale unskillfulness in fashionable rice production. The potency variations are explained mostly by infrastructure, soil fertility, experience, extension services, residency and share of non-agricultural financial gain. [1]

Better Technology, Better Plots, or Better Farmers? Identifying Changes in Productivity and Risk among Malagasy Rice Farmers

We introduce a technique for correctly attributing discovered productivity and risk changes among new production strategies, farmers, and plots by dominant for farmer and plot nonuniformity. Results from Madagascar show that the new system of rice intensification (SRI) is so a superior technology. though regarding half the discovered productivity gains seem thanks to farmer characteristics instead of SRI itself, the technology generates the calculable average output gains of over eighty four. The hyperbolic calculable yield risk related to SRI would notwithstanding build it unattractive to several farmers inside the quality vary of relative risk aversion. [2]

Genetic conservation: a role for rice farmers

The genetic resources of rice are well utilised in efforts to unravel today’s food issues. Rice land races, collected over many decades, became ‘parents’ of the high-yielding, pest-resistant and well-adapted varieties that resulted in new will increase in rice yields. the value of rice to lots of customers is currently just about 0.5 what it had been in 1960 thanks to these gains in productivity.

Probabilistic assessment of chlorpyrifos exposure to rice farmers in Viet Nam

Chlorpyrifos is that the most typical insecticide compound registered for agricultural use in Vietnam. The aim of this study was to judge organophosphate exposure to rice farmers in Vietnam, employing a probabilistic approach. excretory product samples on a 24-h basis were collected from farmers before and post application of chemical. Samples were analysed for three,5,6-trichloro-2-pyridinol (TCP), the most important urinary substance of organophosphate, victimization associate degree protein pre-treatment for extraction and HPLC-MS/MS. Absorbed daily doses (ADD) of organophosphate for farmers were later on calculable from the urinary transmission control protocol levels. The baseline and post-application exposure levels were evaluated at the fifth, 50th, and ninety fifth grade representing low, medium and high-exposure teams within the population. multivariate analysis was applied to look at the association between exposure level and factors. The baseline exposure level, that ranged from zero.03 to 1.98 μg/kg/day was below the chronic tips counseled by international and national bodies. However, the post-application exposure level, that ranged from zero.35 to 94 μg/kg/day exceeded most of the acute tips at the ninety fifth grade level. statistical method provided robust proof for a relationship between post-application exposure level and quantity of organophosphate used, likewise as body coverage of non-public protecting instrumentation.

Factors Influencing Economic Viability of Small Farmer of Rice Production in Bangladesh

The focus of this study was to conduct analysis on tiny rice farmers and to spot the factors and their influence in viability of rice production in Bangla Desh. The study was conducted employing a longitudinal survey created below the Village Dynamics in South Asia (VDSA) project of International Crops analysis Institute for the Semi-Arid Tropics (ICRISAT). a complete of 179,179,156 and 177 tiny rice farms were elite as a sample for the years of 2009, 2010, 2011 and 2012, severally. Among 691 tiny farmers, 562 farmers were viable farmer and 129 farmers were non-viable farmers WHO were manufacturing rice within the study space. the little farmers lived within the same socio-economic atmosphere. The economic surplus of husbandman was 11018.5 tk. 12205 tk., 6006 tk. and 4461 tk. in numerous years. to realize the target discriminant operate analysis was used. For this analysis eight discriminant factors were elite i.e. family size, farm size, education, price productivity from crops, profits from farm, off-farm financial gain, total fastened investment and domestic expenditure. it’s found that off-farm financial gain was the foremost important discriminat issue among the eight factors associated with the discriminating of viable and non- viable of tiny farmers of rice production Besides price from crops, total fastened investment and domestic expenditure were the opposite important factors found throughout all the years.
