    Development, Testing and Evaluation of Inclined Plate Planter for Pelleted Vegetable Seed
    (Punjab Agricultural University, Ludhiana, 2016) Gautam, Anand; Khurana, Rohinish
    Onion (Allium cepa L.), Carrot (Daucus carota L.) and Radish (Raphanus sativus) are important vegetable crop grown throughout the country. Onion, carrot and radish can be grown by direct seeding method which can help in saving labour. Small and irregular shaped seeds lead to variation and placement of the seeds when sown using existing planters. Seed pelleting was done in the ratio of 1:1 to 1:3 so that the physical properties of the seeds are altered to be applicable for use with an inclined plate planter. An inclined plate planter was developed for pelleted seeds. Preliminary evaluation of the developed planter was done in the laboratory for the treated seeds (S1, S2 and S3) using different developed seed plates having 18, 24 and 30 grooves at forward speeds of 1.0, 2.0 and 3.0 km/h. Performance was evaluated on the basis of average spacing, missing index, multiple index and quality of feed index. Based on average seed spacing and index value the optimum combination of direct sowing of onion, carrot and radish was found for S3 seed with 24 groove plate at 2.0 km/h forward speed and 45o inclination angle of plate. Field evaluation of the machine was done on the basis of these selected parameters s in the laboratory evaluation. The machine was used to plant onion, carrot and radish S3 seeds on 100 cm wide beds. The yields observed were 478.80 q/ha, 252.00 q/ha and 322.60 q/ha for onion, carrot and radish respectively. Field capacity of the machine was found 0.164 ha/h and the fuel consumption during the sowing operation was 4.5 l/h. The cost saving in estimation were 94.5and 49.5 percent for onion and carrot, radish crop.
