Silicon (Si) has been shown to suppress diseases of rice such as blast when applied to Si-deficient soils. In 1995 and 1996, Si was applied at 1,000 kg ha-1 to at two locations in eastern Colombia to determine if Si combined with reduced rates of fungicide could be used to manage leaf and neck bl...

The inheritance of the ability of Sogatodes oryzicola to support replication of the rice hoja blanca virus (RHBV) was studied by following the segregation of progeny of crosses between insects of known pedigree and known ability to support virus replication and transmission. Virus transmission to...

Protocols were established for screening rice genotypes for tolerance to water-limited conditions under field conditions. These protocols were successfully used to select the best genotypes for further experiments. Rice genotypes responded differently when subjected to water-limited conditions. E...

Shifting cultivation is practiced by millions of farmers in the tropics and has been accused of causing deforestation and keeping farmers in poverty. The assumed positive relationship between fallow length and crop yields has long shaped such negative opinions on the sustainability and environmen...

Action thresholds for Tibraca limbativentris Stall (TL) on rice were calculated to be 8.8 and 25.8 TL per 10 sweep nets for 30- and 40-day old plants, respectively. Population dynamics of TL at two localities in Valle del Cauca, Colombia, indicated a density of 1.2 TL per sweep (12 TL per 10 swee...

The objective of the forest rehabilitation study with taungya system was to find out optimum method, cash crop species, constraints, and how much this system benefits forest rehabilitation. It was carried out using red meranti (Shorea smithiana) and rubber (Hevea brasiliensis) as plantation trees...
