| Abstract: | The objectives of this research were to study the effect of dosage and methods of sago pith waste application on some soil physical properties, surface runoff and vertical flow water loss, soil erosion and corn yield. Research was conducted in the Tawiri Village, Ambon City. The experiment used a factorial randomized block design which was repeated three times. The first factor was the dosage of sago pith waste and the second factor was the method of sago pith waste application. Response variables measured were the amount of surface water flow, the vertical flow of water, soil erosion, soil physical properties, corn yield, the value of CP and tolerable erosion. The results of experiment indicated that 40 ton.ha -1 of ela sagu dosage applied on soil surface was more effective to increase soil C-organic, vertical flow, aeration pores, available water pores, soil porosity and soil aggregate stability, and to reduce the amount of surface flow, slow drainage pores, bulk density, soil erosion, and was able to supress soil erosion under tolerable erosion value. Optimum dosage was 27.42 ton.ha -1 of sago pith waste mixed with soil which has given maximum corn seed dryweight 6.14 ton.ha -1 , whereas the optimum dosage was 21.42 ton.ha -1 of sago pith waste applied on soil surface gave maximum corn seed dry weight 6.81 ton.ha -1 . Application of 30 ton ha -1 sago pith waste on the soil surface was able to supress soil erosion under tolerable erosion value, which was 0.99 ton ha -1 yr -1 . As much as 40 ton ha -1 of sago pith waste produced the lowest CP respectively 0.24, 0.32, 0.29, 0.28, 0.27, while ela sago on the surface soil produced the lowest value of each CP 0.46, 0.50, 0.50, 0.49, 0.48, and 0.47 to corn at each age period. Differences in the age period of corn showed no significant effect on the value of CP. |
