Abstract

Recently planting site of sugarcane was shifted from lowland to upland area. Sugar cane cultivation in upland has many constraints, especially limited water supply and low nutrition availability. The objectives of this research were to study the influence of  application of composted filter cake on growth and water use efficiency of upland sugar cane. The research was conducted in Jengkol, Kediri. Treatments consist of three factors: frequency of irrigation (once every 1 week, once every 2 weeks, and once every 3 weeks); sugarcane varieties (PS-862 and  PS-864); and  compost doses (0, 2.5, 5, and 7.5 ton ha-1). Split plot design with three replications was used in each  irrigation treatment, using composted filter cake as main plots and sugarcane varieties as sub plots. The results showed that the highest sugar content was  reached at application of 5 ton ha-1   compost  and the  greatest crystal sugar was reached at 3.09 ton ha-1 compost. Compost application at 5 ton ha-1 on each planted row can reduce  frequency of irrigation from once a week to once every 2 weeks.   Keywords: compost of filter cake, frequency of irrigation, upland sugar cane
