Malaria vectors can reach very high densities in villages near irrigated rice fields in Africa, leading to the expectation that malaria should be especially prevalent there. Surprisingly, this is not always the case. In Niono, Mali, villages from nonirrigated areas have higher malaria prevalence than those within the irrigated regions, which suffer from higher mosquito numbers. One hypothesis e...

SUHARDONO and D.B. COPEMAN 2000. Population dinamics of Lymnaea rubiginosa in rice fields and its infection with larvae of trematodes. Jurnal Ilmu Ternak dan Veteriner 5(4): 241-249. Field of irrigated rice paddy was the most suitable habitat as breeding site of snail Lymnaea rubiginosa, the intermadiate host of Fasciola gigantica and other trematodes. Fluctuations in the population of fresh wa...

Pantoea ananatis 1.38 is a strain isolated from the rhizosphere of irrigated rice in southern Spain. Its genome was estimated at 4,869,281 bp, with 4,644 coding sequences (CDSs). The genome encompasses several CDSs related to plant growth promotion, such as that for siderophore metabolism, and virulence genes characteristic of pathogenic Pantoea spp. are absent.

THE RICE LANDS of Malaysia, tolaling 0.6 M ha are broadly classified as either granary or nongranary areas. The granaries comprise 8 large and contiguous irrigation schemes, covering 210,000 ha and producing more than 65 percent of the country's total output; and it is in these granaries that further developine.nt of rice production will bt. concentrated. The nongranaries are either rain-fed or...

We characterized a rice introgression line, YTH34, harboring a chromosome segment from a New Plant Type (NPT) cultivar, IR65600-87-2-2-3, in the genetic background of an Indica Group elite rice cultivar, IR 64, under upland and irrigated lowland conditions in Japan. The number of panicles (as an indicator of tiller number) and number of spikelets per panicle of YTH34 were lower than those of IR...

The worldwide usage of and increasing citations for ORYZA2000 has established it as a robust and reliable ecophysiological model for predicting the growth and yield of rice in an irrigated lowland ecosystem. Because of its focus on irrigated lowlands, its computation ability is limited to the representation of the effects of the highly dynamic environments of upland, rainfed, and aerobic ecosys...

Introduction Arsenic from irrigation water is accumulating in soils (Ullah, 1998; Panaullah et al., 2003). The presence of high As in Bangladeshi soils and continuing use of As contaminated irrigation water may affect the movement of As in soil and accumulation of As in rice (Abedin et al., 2002). Transport of As in soil, as well as uptake by plants is governed by mobility, yet mobility of As i...
