The Effect of Bed Type and Manure On Growth and HerbageYield of Forage Crop In Saline Soil

Abstrak

Plants  growing in  saline  conditions   usually face toxicity problems,  especially   Sodium (Ma)  toxicity that often leads  to crop failene. The research was conducted to evaluate  the effect of bed type and manure on growth  and herbage yield  of forage crop in  salin  soil. The experiment   was arranged in split   plot design with  three replication.   The  first  factor as main plot  was bed type:   G 1    (without bed type) and 02 (with bed type). The second factor as sub plot  was dosage of manure which was devided  into 4 levels KI (0 kg N/ha), K2 (50 Kg Nzha), K3 ( I 00 kg N/ha) and K4 ( 150  kg N/ha). The parameters were observed in  this experiment: plant,  height,  leaf number, fresh yield,   dry yield,   level of death and Sodium  content in  soil (ppm).  Data were analizcd  by analysis of variance.  The differences  among means were determined by using Duncan's   Multiple Range Test. The result  showed that the application   of manure  increased  leaf number,  fresh yield   and dry yield  significantly   (p<0.05).  Application of manure decreased the level  of death and Na content in soil significantly    (p<0.05).  There was no effect of using  bed type on leaf number,  fresh yield.  dry yield,  level  of death and Na content in soil.
