Question
Drum culture technique is used to determine WR of
which of the following crop?Solution
Drum culture technique is used to determine water requirement of lowland rice. In this method, four drum of size 50×50×50 cm are taken i.e. A, B, C and D. A and B have bottom while C and D are without bottom. All the drums are embedded in soil leaving 20 cm above soil surface. Rice is transplanted in drum A, C & D. and rice seedlings without roots are planted in drum B and the data on percolation, evaporation, ET, transpiration and effective rainfall is obtained.
