Abstract

A field trial was carried out for three consecutive seasons (2004-2005, 2005-2006 and 2006-2007) to study the increase of faba bean productivity and improve soil properties by using farm yard manure and irrigation regimes on reclaimed high terrace soils (Aridisols). The experiment consists of three irrigation regimes, which are (after 7, 14 and 21 days), and application of 0.0 and 10 ton/ha farmyard manure (FYM). Superphosphate at a rate of {½ P=20 kg P/Fed) was applied to all treatments at sowing. One faba bean variety was used namely SM-L. The experiment was replicate four times in split-plot design with main plot allotted to FYM treatments and subplot to irrigation regime. Data on grain yield and biomass show that there were significant differences in grain yield between the two FYM levels effects. The irrigation regime also significantly affected grain yield. As expected the addition of FYM to the soils improved grain yield in all irrigated periods compare to without manure (0 FYM), and also in 7 days irrigated were higher than in 14 and 21 irrigated periods. The reduction of faba bean grain yield from 14 to 7 days and from 21 to 7 irrigated days ranges about 5% and 35% for 0 ton/ha FYM treatments, and about 19% and 57% for 10 ton/ha FYM treatments, respectively. However, addition of 10 ton/ha FYM (M1) at irrigation every 7 days interval was significantly higher than in 14 and 21 irrigated days regimes. It can be concluded that the highest faba bean yield was observed in to use 10 ton/ha FYM with irrigation period (every 7 days interval) in the soil reclamation of saline soils and to improved crop productivity.
