AMA, Agricultural Mechanization in Asia, Africa and Latin America (ISSN: 00845841) is a peer-reviewed journal. The journal covers Agricultural and Biological Sciences and all sort of engineering topic. the journal's scopes are in the following fields but not limited to:
The existing area of vegetable planting in India is declining and cannot meet demand due to lack of mechanization. Labor costs associated with sowing and transplanting operations in vegetable planting are very high. Therefore, mechanization in sowing is important for increasing the area of vegetable planting. In this regard, a precision multi-variety transplanter for onion cultivation was evaluated for the selected onion crop, the local sowing variety Punjab Naroyawas. The sowing interval was adjusted to 0.02x0.75 m in the laboratory. A 1.25 m wide floor was created by a rotary cultivator and bedformer, and the average fuel consumption was 6.93 and 7.01 lh -1 for cultivated and non-cultivated soils, respectively. Four lines of onions were sown on each bed using a pneumatic transplanter. Average speed 3. 36Km.H -1, average fuel consumption 2.65Lh -1, average RTR spacing, 20.42cm, the average depth of the seed 2 cm, the average PTP spacing 7.86Cm, average field amount 0. 17Ha.H - It was 1. The mean observation index (PI) of the transplanter was 4.52%. Mean bulbs weight and yield of onion seed by pneumatic precision-mix transplantation machine, 57.45G and 9,562kg. acre relative grafting method -1 and 57.86g and 10,515Kg. Acre -1 was. The cost and time savings of the pneumatic precision high-mix transplanter were 55.12% and 98.53% compared to the transplantation method. The profit-cost ratios for onion sowing by the pneumatic precision high-mix transplanter and the manual transplantation method were 5.11: 1 and 2.62: 1, respectively.
The plastic roller cup feeding and weighing mechanism of the automatic sowing and fertilizing drill was improved for sowing between wheat chickpea (2: 1) and wheat mustard (3: 1). Weighing rollers were selected based on seed shape and size and the number of cells in the periphery. Different types of seed flow from each cup feeding roller were achieved by splitting the seed hopper in separate compartments. For the selection of weighing mechanism, calibration was performed among the seven available cup feeding weighing rollers with different combinations of seed box exposure lengths. The improved intercropping seed drill was calibrated in the laboratory for the required seed rate. The seed rate for wheat-chickpea intercropping is 75 kg / ha for wheat with 4 rollers and 25 kg / ha for chickpeas with 5 rollers on a seed box exposure scale of 7. I found out. The required seed rate for wheat-mustard cropping is 75 kg / ha for wheat with 4 rollers and 6 kg / ha for mustard with 7 rollers on the seed box exposure scale. It turned out. The effective field capacity of the sowing and fertilizing drill for chickpeas was 0.42 ha / h, and that for the mustard mustard intercropping was 0.47 ha / h. As a result of agricultural studies, wheat-chickpea (2: 1) intercropping was performed better than wheat-mustard (3: 1) intercropping and single crops.
