Abstract

In this res arch, a seed-drilling machine with appropriate size was DESIGNed for SMALL FARMS using Auto CAD software. Then three dimensional sample of the machine was prepared by computer and its operation was simulated and recorded on videotape. When the engineering drawings were prepared, the required components were constructed and the machine was assembled according to the drawings.Preliminary workshop evaluation, using polyethylene balls with 3mm diameter, showed that there was a linear relationship between speed and the amount of seeds planted within the range of 2 to 5 kilometer per hour. With regard to mechanical damages of the balls three pieces of seed metering device (selector wheel) with different types of seed cells were constructed and mounted on the machine. The following workshop evaluation confirmed the suitability of the cell type C in which the lowest percent seed damage namely 1.24 percent and percent cell fill of about 97 at traveling speed of 3 kilometer per hour occurred. The work was followed by evaluation of the seed drill on the sand type seed bed and in the field respectively, and its performance was compared with pneumatic German made seed PLANTER. In sand bed tests there was a significant difference between two types of PLANTERs at 1% probability level with regard to mean seed spacing, feeding quality, multiple planting, skips and planting depth indices. According to field test results carried out on two types of planting beds, there was a significant difference between two PLANTERs with regard to mean plant spacing and accuracy range of 2 indices as well as feeding quality, multiple planting, skips, percent of germination, deviation from planting line and plant leaf area and dry weight of plant indices at 1% probability level and mean planting depth and hypocotyls diameter indices at 5% probability level. Since the evaluation of the selector wheel was carried out for only one seed size of the seed, therefore further investigations are need to be made with regard to different types of ce& before different types of selector wheels according to seed size and planting spacing are recommended and constructed. To improve other indices and also to improve planting conditions of the seeds and to increase the field emergence rate for the manual PLANTER it is suggested that further investigation of seed delivery tube as well as soil engaging components be made and after making necessary modifications, a laboratory soil bin test as well as field test be carried out for the PLANTER.
