NICDAO, ANTHONY C. University of the Philippines Los Bafios. April 2011. Design and Development of a Sweet Sorghum Seeder with Fertilizer Applicator Major Professor: Dr. Arsenio N. Resurreccion This study was conducted to design and develop a sweet sorghum (Sorghum bicolor (L.) Moench) seeder with fertilizer applicator. The performance of the seed metering plate was evaluated in terms of travel speed(S), hopper inclination (J, and hopper capacity (H). The fertilizer metering device was evaluated in terms of speed (S), hopper regulator opening (O), and hopper capacity (H). The combinations that gave the ideal discharge and less broken seeds were treatments, S, x I, x Hg (2kph, 25° inclination, and 1/8kg hopper capacity)for 10-hole; S;x I3 x Hz (2kph, 45°, and 1/2 kg hopper capacity) for 14-hole; and S, x I; x H3 (2 kph, 45°, and % kg hopper capacity) for 20-hole metering plates. The results revealed that S; (2 kph) gave the most appropriate speed for 10-hole, 14hole, and 20-hole metering plates with the least broken seeds among the treatments. Seed spacing uniformity had a standard deviation of 2.42 cm and coefficient of variation of 21.91%. The field capacity of the seeder was 0.143 ha/h and efficiency of 83.14%, The cost of fabricating the machine was PhP16,323.00. Results of the investment analysis showed a break even point of 12.52 operating days and internal rate of return of 40.28%. Result of the farmers assessment on the overall performance of the sweet sorghum seeder with fertilizer applicator categorized the machine as good technology in terms of.
