Profitability of rice production using a drum seeder

An experiment was carried out to evaluate the profitability of rice production using a drum seeder developed in the department of Farm Power and Machinery, Bangladesh Agricultural University, during transplant aman seasons July-December, 2004 at Mymensingh. Three planting methods viz., direct seeding with drum seeder, broadcasting and transplanting were used in the experiment. The treatments were replicated three times in Randomized complete block design. The results revealed that all the treatments under the study had significant influence on the yield and yield attributes of rice. Drum seeded crop produced the highest plant height 101.49 cm, panicle length 22.84 cm, leaf len9th 52.39 cm, root length 11.11 cm, number of panicles 382.61 m-2, number of effective tillers 8.55 hill-I, number of total tillers 9.6 hill-1, wt. of straw 29.84gm hill-1, straw yield 6882kg ha-1, harvest index 44.42 %, and biological yield 12902kg ha-1. Crop in broadcasting method produced the highest number of noneffective tillers 2.3 hill-1. Crop established with a drum seeder resulted in higher grain yield 5634 kg ha-1, which was at par with transplanting 5213 kg ha-1 and superior over broadcasting 3505 kg ha-1. Not only the yield, but also the highest net revenue of Tk 27541 ha-1 with benefit cost ratio of 1.92 was also recorded by the drum seeding. The cost of crop establishment in transplanting method was 1.71 times higher than that from seeding by the drum seeder. It might be concluded that the drum seeder technique would be more profitable than transplanting method of rice production in Bangladesh.
