The growing demand for agricultural output and limited resources encourage precision applications to generate higher-order output by utilizing minimal inputs of seed, fertilizer, land, and water. An electronically operated planter was developed, considering problems like ground-wheel skidding, field vibration, and the lack of ease in field adjustments of ground-wheel-driven seed-metering plates. The seed-metering plate of each unit of the developed planter is individually driven by a brushless direct current (BLDC) motor, and a BLDC motor-based aspirator is attached for pneumatic suction of seeds. The revolutions per minute (RPM) of the seed-metering plate are controlled by a microcontroller as per the received data relating to RPM from the ground wheel and the current RPM of the seed-metering plate. A feedback loop with proportional integral derivative (PID) control is responsible for reducing the error. Additionally, each row unit is attached to a parallelogram-based depth control system that can provide depth between 0 and 100 mm. The suction pressure in each unit is regulated as per seed type using the RPM control knob of an individual BLDC motor-based aspirator. The row-to-row spacing can be changed from 350 mm to any desired spacing. The cotton variety selected for the study was RCH 659, and the crucial parameters like orifice size, vacuum pressure, and forward speed were optimized in the laboratory with the adoption of a central composite rotatable design. An orifice diameter of 2.947 mm with vacuum pressure of 3.961 kPa and forward speed of 4.261 km/h was found optimal. A quality feed index of 93% with a precision index of 8.01% was observed from laboratory tests under optimized conditions. Quality feed index and precision index values of 88.8 and 12.75%, respectively, were obtained from field tests under optimized conditions.

Precision machinery is one of the most important technology in the recent decades in respect to judicious use of resources. In precision machinery one of the most important machine is seeding machines because it picks the seed from the hopper and individually placed in field. An effort has been made to optimize the operational (forward speed and vacuum pressure) and design (nozzle diameter) parameters of the precision seed drill. For optimizing the metering mechanism three parameters i.e. nozzle diameters: 2.00, 2.50, 3.00, 3.50 and 4.0 mm; forward speed: 0.27, 0.55, 0.83, 1.11 and 1.38 m/s and vacuum pressure: 19.33, 39.32, 43.98, 58.64 and 68.63 kPa were selected. The seed to seed spacing was 300 mm. The RSM technique was used to optimize the above parameters. The machine was evaluated on the basis performance parameters like miss index, multiple index, quality of feed index and precision. The optimum value for forward speed, vacuum pressure and the nozzle holes diameter was 0.83 m/s, 43.98 kPa and 3.50 mm, respectively. The most important variable that governs planting phenomenon for vegetable pigeon pea seed is nozzle diameter as well as vacuum pressure.

Under the condition of high-speed sowing (12-16 km/h), due to the high rotational speeds of the seed disk, the seeds leave the disk at an excessively high speed, which challenges the seed-picking capacity of the belt-type high-speed seed guide device. In this paper, the theory of seed-picking mech-anism is analyzed, and performance optimization tests are completed to further improve the operation effect of the seeder. The mechanical model of seed picking was established through the force analysis of seeds. The influence of vacuum degree, feeder wheel rotation speed, and seed picking angle on seed picking quality and the parameter range of each factor were obtained by single factor test. A three-factor five-level quadratic orthogonal rotation combination test was performed, and the test re-sults were refined and evaluated. The test factors used were vacuum degree, feeder wheel rotation speed, and seed picking angle. The test indexes used were the seed picking rate, re- picking rate, and miss- picking rate. According to the results, the seed picking rate was 99.89%, the re-picking rate was 0, and the miss-picking rate was 0.11% when the vacuum degree was 6.89KPa, the feeder wheel rota-tion speed was 568.95rpm, and the seed picking angle was 7.6°.
