Fifteen cassava (Manihot esculentaCrantz) genotypes were grown at two field sites of Nigeria from 1994 to 1996 (Ibadan: 28±5°C, altitude 210 masl and Jos: 18±5°C, altitude of 1260 masl) to evaluate the use of chlorophyll fluorescence in screening for cold tolerance in cassava. At 12 months after ...

A range of physical means of manipulating yam tuber dormancy was tested, including the use of temperature, water, electric shock, microwave, heat and storage treatments. Most treatments had very little practical effect on tuber dormancy though differences in dormancy length between clones were de...

Life table studies were conducted to assess the effect of constant temperature on the rate of population growth of the cassava mealybug, Phenacoccus manihoti Matile‐Ferrero. Four temperatures, between 20 and 30.5 °C, were tested. An inverse relationship was observed between temperature and most d...

Chamelia (catchment area = 1603 km2 ), a tributary of Mahakali, is a snow-fed watershed in Western Nepal. The watershed has 14 hydropower projects at various stages of development. This study simulated the current and future hydrological system of Chamelia using the Soil and Water Assessment Tool...

The Andean potato tuber moth, Symmetrischema tangolias (Gyen) [Lepidoptera, Gelechiidae], is an economically important pest of potato (Solanum tuberosum L.) in the mid-elevated Andean region and an invasive pest of partially global importance. Determination of the pest's population life table par...

Using biophysical and social analysis methods, this paper evaluated agricultural practices under changing climate in the Koshi Basin and assessed adaptation options. Agricultural trend analysis showed that in the recent three to four decades, the total cultivated area had declined in all parts of...
