Comparative Evaluation of Maize Planters in Conservation Agriculture under Black Cotton Soil of Central India

Abstract

The present study was conducted at ICAR-Central Institute of Agricultural Engineering, Bhopal research farm to study the effect of no-till planters such as inclined plate planter and broad bed shaper-cum-planter on yield, energetics and economics of maize crop production and compared with conventional practices of maize sowing using seed-cum-fertilizer drill. The maize hybrid variety of DMRH-1303 was sown in kharif season of 2019 using inclined plate planter and broad bed shaper-cum-planter under wheat residue load 8 t/ha (HI-1544). The wheat was harvested by combine harvester and its residue was chaffed using shredder. The actual field capacity and field efficiency of inclined plate planter, broad bed shaper-cum-planter and seed-cum-fertilizer drill were observed as 0.31, 0.32 and 0.39 ha/h and 51.67, 58.18 and 76.47%, respectively. The energy consumption for shredding of wheat straw was 399.31 MJ/ha. The energy consumption was maximum in case of sowing with convention seed drill (1965.30 MJ/ha) including single pass of each cultivator and rotavator, which was followed by broad bed shaper-cum-planter under permanent bed condition (792.39 MJ/ha) and inclined plate planter under permanent bed condition (468.77 MJ/ha). The broad bed shaper-cum-planter and inclined plate planter saved energy consumption by 59.7% and 76.14%, respectively as compared to conventional seed-cum-fertilizer drill.The use of inclined plate planter (Rs. 652 per ha) or broad bed former-cum-planter (Rs. 664 per ha) could save 67% in cost of operation compared to seed-cum-fertilizer drill (Rs. 2017 per ha).

Research and Development for the Hurdle Avoidance During Transplanting Manipulation Based on Kinect Vision Processing

“…In this design, Kinect1.0 RGBD vision processor is used which is shown in Fig. 4, which contains two depthsensing cameras and one RGB infrared camera and its stable and effective sensing distance is 500~4000 mm (Sawant et al, 2020). Two depth-sensing cameras can complete the collection of seedling height information.…”
