AL-ISSA, TAHA A. and RAOUL E. NASR, 2005. A financial comparison between conventional, conservation and no-tillage systems used in barley production under rainfed conditions in Jordan. Bulg. J. Agric. Sci., 11: 503-509
Barley (Hordeum vulgare L.) is the most widely grown cereal crop under semi-arid conditions of Jordan. The traditional or conventional tillage systems practiced in Jordan depleted soil resources and resulted in lower crop yields. The use of conservation tillage system increases the efficiency of soil moisture storage. Therefore, the conservation tillage system is expected to increase crop yield as compared with the conventional tillage systems. A field study was conducted during the growing season of 2002/2004 in Northern Jordan, to investigate the performance of barley under conventional or traditional tillage using a disk plow, conservation tillage using a chisel plow and no-tillage systems in a fallow barley rotation. Cost and returns of the production process were calculated. All systems showed positive gross margins. Conservation tillage system showed the highest gross margin and superiority to the prevailing conventional tillage system and no-tillage system simply because it maintained the highest total revenue. Therefore, barley-growing farmers under rainfed conditions in Jordan are recommended to try and test the conservation tillage system using the chisel plow. However, In order to pass a more sound economic judgment, these technologies should be tested using farm level data.
