collection capacity, rice straw loss in the field,and diesel consumption (Table 3).
Except for loose straw obtained
from the gathering machine, straw roller-bales collected by the
other baler machines had almost the same length of 70 cm. This
could be attributed to the machines having the same length of
roller-chambers. The specific weight of the roller-bales ranged from
73 to 104 kg m−3 at an MC of 12.4 (±1.21)% (MC of rice straw was
slightly reduced after baling). Collection capacity ranged from 0.87
to 2.47 t h−1. Rice straw loss in the field (which remained in the field after collection) was very different and ranged from 18 to 43%.
Diesel consumption ranged from 4.2 to 11.9 L t−1.
