The two major virus-specific proteins found in plants infected by maize stripe virus (MStpV), rice hoja blanca virus (RHBV), and Echinochloa hoja blanca virus (EHBV) were compared by serological and one-dimensional peptide-mapping analysis. When total cellular proteins from healthy plants and pla...

To fully exploit the diversity in African rice germplasm and to broaden the gene pool reliable information on the population genetic diversity and phenotypic characteristics is a prerequisite. In this paper, the population structure and genetic diversity of 42 cultivated African rice (Oryza spp.)...

The study analysed quality attributes that determine consumers' preference and demand for food by taking the case of rice consumption. This study also explored the segmentation of the rice market in Tanzania based on the rice products' attributes. Surveys and conjoint ranking exercises were condu...

This paper recounts of a household survey done in Long Segar, East Kalimantan, in June 1997, covering the period from 1991-1997. This survey is a follow-up survey of land use, conducted first in 1980 (1962-1980) and again in 1991 (1981-1991). The initial purpose of the 1997 survey was to assess c...

The System of Rice Intensification (SRI) - a package of practices designed to grow more rice with less water - is being widely promoted by governments and NGOs in India. In 2010-11, IWMI-Tata Program, in collaboration with local partners, undertook a study covering 2234 rice farmers in 13 major r...

We assessed the impact of laser land leveling technology in rice-wheat (RW) systems of north-west India using data collected from household surveys in 2011. We compared crop yield and total irrigation time required per season between laser leveled (LLL) and traditionally leveled (TLL) fields. Las...

This study assesses the impact of climate change on hydrological processes under rice intensification in three headwater inland valley watersheds characterized by different land conditions. The Soil and Water Assessment Tool was used to simulate the combined impacts of two land use scenarios defi...
