due to the important role of subsurface drainage in managing the ground water level, there are many researches focused on finding a new and more economic way to develop subsurface drainage technologies. lack of proper drainage system in northern iran has caused huge implantation of rice and it is impossible to have second implantation in this region. one reason of insufficiency of current drain...
Cyanobacteria are one of the important components of rice field ecosystems. Few of which have the ability to fix atmospheric nitrogen and are therefore, considered as natural biofertilizer which enrich the productivity of rice. Calothrix is one of the potent groups of N2 fixing cyanobacteria and is very common in rice grown areas of Assam. Therefore, the present survey conducted in rice field s...
Knowing where, when, and how much rice is planted and harvested is crucial information for understanding the effects of policy, trade, and global and technological change on food security. We developed RiceAtlas, a spatial database on the seasonal distribution of the world's rice production. It consists of data on rice planting and harvesting dates by growing season and estimates of monthly pro...
Japan's rice sector is supported by high prices paid by consumers that allow many farm households to maintain small rice farms. Japan's government controls trade within a tariff-rate quota and imposes a prohibitively high tariff on imports outside the quota. Within Japan, diversion programs pay farmers to substitute other crops for rice since, without government-mandated diversion, supply would...
Impact of Rural Road Improvement on High Yield Variety Technology Adoption: Evidence from Bangladesh
Rural road improvement that enhances access to input and output markets and agricultural extension services may aid agricultural technology adoption. There is a growing body of literature on the impact of rural roads on technology adoption. However, most studies have so far relied on cross-sectional surveys comparing households with and without road improvement, which have causal attribution pr...
This article offers an account of embodied exchange with the world that associates conscious operations with actively inferring the causes of our sensations. Its agenda is to link formal (mathematical) descriptions of dynamical systems to a description of perception in terms of beliefs and goals. The argument has two parts: the first calls on the lawful dynamics of any (weakly mixing ergodic) s...
The transfer of arsenic to rice grains is a human health issue of growing relevance in regions of southern Asia where shallow groundwater used for irrigation of paddy fields is elevated in As. In the present study, As and Fe concentrations in soil water and in the roots of rice plants, primarily the Fe plaque surrounding the roots, were monitored during the 4-month growing season at two sites i...
