The weight of available straw per ha means the yield (t ha−1)
of cut straw left in the field before being collected (i.e., not including
the straw stubbl that remain in the field). The weight of collected
straw was taken from the calculation for collection capacity. The
measurement ofthe collected straw was done two hours after measuring
the available rice straw, causing the rice straw to lose weight.
To avoid this error, the weight of both collected and available rice
straw were converted into the same moisture content.
