Save And Grow Farming Systems Fact Sheet 2
|
Traditionally rice has been cultivated in most of Asia as follows: fields are first flooded then ploughed to create soft muddy soil often overlying a dense, compacted layer that restricts downward loss of water. Rice seedlings 20 to 60 days old are then transplanted to the fields in clumps of two to four flooded with 5 to 15 cm of water until the crop matures. That system has enabled the cultivation of rice for millennia at low, but relatively stable yields. When the Green Revolution introduced high-yielding varieties, mineral fertilizer and chemical pest control, per hectare productivity in many Asian rice fields doubled in the space of 20 years. A set of crop, soil and water management practices known as the System of Rice Intensification (Sri) takes a strikingly different approach. Seedlings 8 to 15 days old are transplanted singly, often in grid patterns with spacing of 25 x 25 cm between plants.
