This study presents the availability of fish feed ingredients and their nutritive value in Lakshmipur region, southern Bangladesh considering the presence of large number of fish farms in those areas. A survey was conducted to collect the ingredients from the local markets and fish farms of the area. A range of commonly used feed ingredients for fish farming was available in the markets that in...

Intensified use of agricultural inputs, particularly fertilizer, is a possible route to improved agricultural productivity. Field trials of these technologies show substantial increases in yields, but typically are done on highly monitored experimental plots rather than by farmers themselves. Returns to a certain technology might be quite different on real-world farms than on experimental farms...

While wind farms have no inherent storage to supply power in calm conditions, this paper demonstrates that large tidal turbine farms in channels have short-term energy storage. This storage lies in the inertia of the oscillating flow and can be used to exceed the previously published upper limit for power production by currents in a tidal channel, while simultaneously maintaining stronger curre...

Beyond the conventional role of providing food, rice farming in European Mediterranean wetlands performs a valuable non-marketable function related to the provision of environmental services. Rice and biodiversity are jointly produced, so that provision of flooded-rice-fields based environmental services depends crucially on private profitability of rice farming. Recent reforms of the Common Ag...

Implications of increasing labour costs and the development of herbicide resistance for profitable weed management in Philippine rice farming systems are investigated. The study employs RIMPhil (Resistance and Integrated Management in the Philippines), a bioeconomic simulation model developed to provide a comprehensive assessment of integrated weed management programmes for the control of annua...

Rice, Oryza sativa L., is the staple food for more than three billion people or over half the world’s population (FAO 2004). It provides 27 per cent of the dietary energy supply and 20 per cent of dietary protein intake in the developing world. Grown in at least 114 mostly developing countries, rice is the dominant crop in Asia where it covers half of the arable land used for agriculture in man...

Spodoptera frugiperda (Smith) is a polifagous insect of major economic impact in the western hemisphere and exhibits two strains (i.e., corn and rice) that are morphologically identical but differ in ecology, genetics and physiology. In this work we identified these strains and their respective hybrids by using a PCR-RFLP of the COI gene and PCR of the tandem region FR. Moreover, we performed a...
