Environmental Impacts Of Modern Agricultural Technology Diffusion In Bangladesh: An Analysis Of Farmers' Perceptions And Their Determinants, S Rahman Jan 2003

Environmental Impacts Of Modern Agricultural Technology Diffusion In Bangladesh: An Analysis Of Farmers' Perceptions And Their Determinants, S Rahman

School of Geography, Earth and Environmental Sciences

Farmers' perception of the environmental impacts of modern agricultural technology diffusion and factors determining such awareness were examined using survey data from 21 villages in three agro-ecological regions of Bangladesh. Results reveal that farmers are well aware of the adverse environmental impacts of modern agricultural technology, although their awareness remains confined within visible impacts such as soil fertility, fish catches, and health effects. Their perception of intangible impacts such as, toxicity in water and soils is weak. Level and duration of modern agricultural technology adoption directly influence awareness of its adverse effects. Education and extension contacts also play an important …

Farm-Level Pesticide Use In Bangladesh: Determinants And Awareness, S Rahman Jan 2003

Farm-Level Pesticide Use In Bangladesh: Determinants And Awareness, S Rahman

School of Geography, Earth and Environmental Sciences

Farmers' awareness of beneficial and harmful effects of pesticides and factors determining use of pesticides were analyzed using survey data from 21 villages in three agro-ecological regions of Bangladesh. Pesticide cost accounts for about 7.7% of the gross value of output in cotton, 3.6% in vegetables, 2.5% in potato, 1.8% in modern rice, 1.6% in spices and less than 1% in other cereal and non-cereal crops. About 77% of farmers (highest 94% in Comilla) used pesticides at least once (37% applied once and 31% applied twice, and the rest applied for 3-5 times) in a crop season. Cultivation of traditional …

A New Hplc‐Elsd Method To Quantify Indican In Polygonum Tinctorium L. And To Evaluate Β‐Glucosidase Hydrolysis Of Indican For Indigo Production, Lg Angelini, E Campeol, S Tozzi, Et Al Jan 2003

A New Hplc‐Elsd Method To Quantify Indican In Polygonum Tinctorium L. And To Evaluate Β‐Glucosidase Hydrolysis Of Indican For Indigo Production, Lg Angelini, E Campeol, S Tozzi, Et Al

Peninsula Medical School

A method to quantify the indigo precursor indican (indoxyl-β-d-glucoside) in Polygonum tinctoriumL. has been developed. Plant material was extracted in deionized water, and indican was identified and quantified using high performance liquid chromatography (HPLC) coupled to an evaporative light scattering detector (ELSD). Results confirmed that with this method it is possible to measure indican content in a short time, obtaining reliable and reproducible data. Using this method, leaf indican content was quantified every 15 days during the growing season (from May to October) in P. tinctorium crops grown in a field experiment in Central Italy. Results showed that indican increased …
