EFFECTIVENESS OF TRANSPLANT DATE AND SOWING DENSITY RELATED TO TILLERING CAPACITY OF RICE (Oryza sativa L.)

Each year, in many countries, there is low rice production due to their traditional practices. Yields and incomes are low, despite the use of lots of inputs. However, other countries are increasing their rice production potential by improving agricultural techniques. The main objective was for assessing the transplant date and the density of sowing on tillering capacity, with a view to improving traditional peasant practices and increasing production potential rice. It was conducted using a split-plot design. It essentially consisted of setting up trials in rural areas for two different years. At planting, the improved variety RWA24 was selected as experimental material. Trials resulted in an average of up to more than 21 total tillers, and more than 12 fertile tillers per plant of rice. This greater number of tillers was recorded with the combination of two yield factors according to the model of the System of Rice Intensification (12 days old plants and transplanting to 1 strand per seed hole). With few inputs of seeds, the rice farmer can therefore improve his production by adopting these techniques to the detriment of traditional practices.
