In India, especially in West Bengal, children are mainly associated with agricultural work (potato cultivation) in rural areas due to poor socioeconomic conditions. Children have to perfo...

Abstract: Potato virus Y a type species of the genus potyvirus infects several crops in the family solanaceae. PVY isolated from field infected peppers was identified on the basis of host reaction, serological and molecular characterization. The result of ELISA, Immunoblot electrophoresis and Immuno Capture Reverse Transcription Polymerase Chain Reaction   (IC-RT-PCR) indicated that...

Using panel data for 2008 and 2011, the analysis describes marketing dynamics – entry, exit, and persistence of participation, and the trends in marketing intensity associated with those dynam...

This study aims to explore the potential and advantage of using the red-edge spectral bands of the forthcoming Vegetation and Environmental New micro Spacecraft (VENμS) for assessing Leaf Area Index (LAI) in field crops. Field spectral data were collected from experimental plots of wheat and potato at the northwestern Negev, Israel. These data were resampled to the VENμS bands being used for ca...

Introduction There are many analytical challenges encountered with the extraction and quantification of pesticide residues in difficult sample matrices such as tuber crops, like yam (Dioscorea spp.), taro (Colocasia esculenta) and sweet potato (Ipomoea batatas L.). In our experience, a workflow solution based on extraction using the accelerated solvent extraction technique, followed by determin...
