Labor Saving Technique for Production of High Quality Welsh Onion by Improved Molding and Fertilizer Application Method (Part 2)

Labor Saving Technique for Welsh Onion Cultivation Using a Fertilizer Applicator-Ditcher

Abstract

A fertilizer applicator-ditcher saves labor and cultivation costs for welsh onion. Work using the fertilizer applicator-ditchers was compared with conventional in ando and sandy soils. This fertilizer applicator-ditcher had 736-mm-long moldboards. Ditches produced using this device were fit for welsh onion cultivation in both fields. Fertilizer placement using the device was 1cm deep and 4cm from the ditch center. Work using this device was 10 times faster than conventional work in the ando soil field and 13 times faster in the sandy soil field. Moreover, the land area coverage increased to 3.8-5.3 times that of conventional work. Yields obtained using this device resembled that for a conventional work in the ando soil field. However, top dressing was necessary to maintain an equivalent yield in the conventional section.
