Crops grown and field operations
Sorghum is a dominant grown crop, constitutes about 85% of the
cropped area, followed by sesame, while sunflower and cotton are
sown in limited areas where rain amount is sufficient for their
growth. Land preparation and seeding operations usually start
when the accumulative rainfall reaches about 100 to 125 mm,
which is sufficient for establishing crops. This usually occurs during
the second and third week of July. The wide level disk plow is the
main machine used for seedbed preparation and seeding
operations. However, deep plowing (chiseling) and shallow plowing
(disk harrowing) and row crop planter are sometimes practiced in
limited areas. Weed control usually starts 2 to 4 weeks after crops
germination. Hand weeding is the common practice, however, due
to shortage and high expense of labors, mechanical weed control
(Sarwala operation) by WLD as well as herbicides application are
recently adopted. Tractors of 75 to 80 ha are the main source of
farm power; however, big tractors were recently introduced to
operate large and heavy implements for improving timeliness of
agricultural operations. According to the used machinery and
cultural practices there are three farming system practiced; namely
conventional, zero-tillage and heavy machinery farming systems.
The mechanized farming system consists of large commercial
farms 210 to 420 ha or more.
