Manual Paddy harvesting by SEVAI Women Self Group Members |
Paddy
Harvesting in SEVAI is done by manually Rice Paddy harvesting is the process of
collecting the mature rice crop from the field. Paddy harvesting activities
include cutting, stacking, and handling, threshing, cleaning, and hauling. SEVAI
applies good harvesting methods to be able to maximize grain yield. To harvest
manually, SEVAI Self Help Group members cut the rice with a sickle at the stems
close to the ground. Manual harvesting system is most common in SEVAI. It
includes the rice crop is cut with simple hand sickle 10-15 cm above the ground
level. After harvesting the rice crop put together in bundles and left on the
field itself for drying for easy threshing. Taking the average duration of the
crop as an indication, SEVAI drains the water from the field 7 to 10 days
before the expected harvest date as draining hastens maturity and improves
harvesting conditions. When 80% of the panicles turn straw colour, the crop is
ready for harvest. Even at this stage, the leaves of some of the varieties may
remain green. It is confirmed: maturities by selecting the most mature dehusk a
few grains. If the rice is clear and firm, it is in hard dough stage. When most
of the grains at the base of the panicle in the selected tiller are in a hard
dough stage, the crop is ready for harvest. At this stage harvest the crop,
thresh and winnow the grains. Dry the grains to 12% moisture level for storage.
Grain yield in rice is estimated only at 14% moisture for any comparison. Manual
system using manually operated tools is common in SEVAI Target area of paddy cultivation.
This includes use of traditional tools for threshing such as threshing racks,
simple treadle threshers and animals for trampling. Harvest paddy rice at the right
moisture content. At maturity, about 80% of the grains turn yellow whilst part
of the stems and leaves remains green. Panicle maturity normally occurs at
about 28-34 days after heading. Timely harvest will reduce yield loss due to:
Grain shattering, cracking of grains in the field and grain breakage during milling,
Lodging and grain discolouration, under wet weather, Birds and rodent attack. Harvesting is an
operation of cutting, picking, plucking, digging or combination of these for
removing the useful part or economic end product, part from the plant.
Threshing is the process of separating the grain from the straw. It can be
either done by hand.-Govin
