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. |
