Possibility of Using Air-Blast Duster for Broadcasting Soaked Paddy
This study aims to investigate the possibility of using the air-blast duster as a broadcaster for the direct-seeding of soaked paddy rice in flooded fields. In order to achieve that four blower air stream velocities of 55, 68, 77 and 86 m/s, four different metering chamber volume of 17, 24, 31 and 38cm3 and three tilt angles of the seed blowing duct of 0, 5 and 10º were studied. These variables were tested and analyzed statistically. The main obtained results were as follows; the best results of coefficient of variation for uniformity of seed distribution and seeds density were 18.5% and 643 seeds/m2, respectively, which obtained at the metering chamber volume of 24 cm3, an air stream velocity of 68 m/s and a tilt angle of 5º. The effective field capacity of the distributor was 1.88 fed/h at the same previous operating factors. The economic evaluation also showed the feasibility of using a knapsack power duster as an alternative method to the traditional sowing methods with a decrease of about 35% in the total operating costs.
