Development of the Seed Drill to Suit Planting in Wet Soil

Abstract

In this study, the seed drill with double disk furrow openers was developed to suit planting in wet soil (Heraty sowing) by adding an auxiliary furrow opener, disk cleaning blade and soil firming roller. The performance of the developed seed drill was evaluated at different planting forward speeds of 1.8, 2.3, 3.1, and 4.2 km/h; different sowing depth of 5, 6 and 7 cm; and two different soil moisture content of 34.5 and 31.1% (d.b.). The emergence ratio, emergence period, seed scattering, slippage ratio were measured, and also the required power, consumed energy and total cost were estimated. The obtained results revealed that the developed seed drill can used for sowing in wet soil (Heraty sowing) at planting forward speed not exceed a limit of 2.3 km/h, sowing depth ranged between 5 - 6 cm and soil moisture content not exceed 31.1% (d.b.).
