Given a curve of genus 3 with an unramified double cover, we give an explicit description of the associated Prym variety. We also describe how an unramified double cover of a non-hyperelliptic genus 3 curve can be mapped into the Jacobian of a curve of genus 2 over its field of definition and how this can be used to do Chabautyand Brauer-Manin type calculations for curves of genus 5 with an unr...
The Indo-Swiss collaboration in Biotechnology (ISCB) initiated in Phase IV a pigeon pea network considering the importance of pulses in the food and nutrition security of India. Pulses are grown on rainfed marginal lands with meagre nutrient and pest managements. Pigeon pea (Cajanus cajan L.) is the second largest pulse crop and is an important source of dietary proteins in India. India contrib...
Cassava (Manihot esculenta Crantz) is a highly productive tuber crop growing on marginal land, providing rural communities in India with nutritious food, as well as income generated by huge industrial demand for sago and starch. In Tamil Nadu (TN) alone it supports over 10,000 smallholder farmers. To sustain the livelihoods of this community of smallholder farmers, the Indo-Swiss Collaboration ...
Perennial herbaceous crops can become the main basis for renewable energy production in agricultural ecosystems in future. To determine the plant species that are the most suitable for biomass production, their biological peculiarities and productivity, biochemical composition and thermophysical properties, social and ecological impact must be investigated thoroughly. The local varieties of per...
Rice is the staple food for more than half of the world’s population. Although rice production has doubled in the last 30 years as a result of the development of high-yield, widely adaptable, resource-responsive, semi-dwarf varieties, the threat of a food crisis remains as severe as it was 60 years ago due to the ever-increasing population, water scarcity, labor scarcity, shifting climatic cond...
Subsistence farmers may not respond to market incentives if their resource allocation decisions are based on shadow prices. This may lead to “puzzling” results from an economic point of view if shadow prices are not taken into account. Subsistence maize farmers in rural Mexico are an example with their non-response to decreasing maize prices after NAFTA. I analyze the true value measure of maiz...
The importance and extent of wine consumption in all life aspects at the Holy Land is well documented. The Muslim influence in this region led to the abandonment of winemaking practices, and possible loss of indigenous wine varieties. Here we present a country wide collection of the local grapevine population including wild and cultivated forms, and its characterization by genetic, ampelographi...
The general objective of this study was to trace the intensi®cation process on sandy soils in the Birni N'Konni area of south central Niger and to identify the role of traditional and modern inputs. The primary hypothesis is that farmers intensify ®rst using traditional inputs, such as traditional varieties, labor and manure, and turn to modern inputs, like inorganic fertilizer, improved variet...
Improvements in water productivity and yield arise from interactions between varieties (G) and their management (M). Most G×M interactions considered by breeders and physiologists focus on in-crop management (e.g. sowing time, plant density, N management). However, opportunities exist to capture more water and use it more effectively that involve judicious management of prior crops and fallows ...
