Abstract:
Rice (Oryza sativa L.) is a cereal that feeds billions of people and serves as a primary staple food. Its production will be required to increase with the rapid increase in population in the future decades. However, rainfed lowland rice in many places are prone to drought and limiting yield. A field experiment was conducted to evaluate the potentiality of potassium fertilisation on compensating the negative effect of drought on rice grain production. Under water stress at the reproductive stage, rice grain production was more limited than water stress at the vegetative stage and higher dose of potassium application substantially compensates the negative effect of water stress, though the extent of effect of potassium was genotypic dependent.
