Description Rice (Oriza sativa) is a major crop in Punjab. Rice is grown in area of 2.85 million hectares
with production of 16.9 million tonnes and it is estimated that 21 million tonnes of paddy
straw produced each year, in Punjab. Paddy straw has very limited end use. Burning of paddy
straw not only causes air pollution but also, is a reason for depletion of natural recourses.
Paddy straw chopper with combine cutting head mechanism helps in solution of this problem.
The study was conducted to evaluate the performance of chopper with various independent
variables. Two levels of number of days after combine harvesting (immediate and after 7
days), two levels of cylinder used (single cylinder and double cylinder) and three levels of
forward speed (1.8, 2.4 and 3.0 km/h). Their effects were studied on dependent parameters
like size of cut of the straw, uniformity of straw spread and fuel consumption. Wheat sowing
technologies were evaluated with treatments as T1= Sowing by ZTD immediately after
rotavator operation after chopping, T2= Sowing by ZTD after 7 days of rotavator operation
after chopping and T3= Sowing by spatial ZTD. Percent sizes of cut (up to 4 cm) decreased
with increase in number of days between combine harvesting and chopping of paddy straw. It
also, decreased with increase in forward speed. Percent size of cut (up to 4 cm) increased
when double cylinders are used instead of single cylinder. Fuel consumption (l/ha) decreased
with increase in number of days between combine harvesting and chopping of paddy straw
and increase in forward speed . Fuel consumption (l/ha) increased with use of double
cylinders. Grain yield was found non significant for different sowing treatment but it
decreased with increase in number of days between combine harvesting and chopping of
paddy straw. Maximum grain yield was 5498 kg/ha and lowest was 3005 kg/ha. Based on the
operational performance, chopping of paddy straw immediately after combine harvesting of
paddy using paddy straw chopper with combine cutting head mechanism using double
cylinder at forward speed 1.8 km/h and then sowing with spatial ZTD (N1C2F1T3) was found
more appropriate wheat sowing technology among different sowing techniques.
