Abstract

This research aimed to determine the effectiveness of several types of liquid organic fertilizer (LOF) derived from plant waste and the dose of P fertilizer on the growth and yield of upland rice on degraded acid soil. The treatments consisted of two factors. The first factor (A) was several types of LOF consisting of A1 (control), A2 (LOF containing isolates of P-solubilizing bacteria), A3 (LOF-banana waste), and A4 (A2+A3). The second factor (B) was fertilizer doses consisting of B1 (50% of the recommended dose of P fertilizer), B2 (75% of the recommended dose of P fertilizer), and B3 (100% of the recommended dose of P fertilizer). The treatment combinations were arranged in a factorial randomized block design with three replications. The research results showed that applying either LOF-banana waste or the mixture of LOF-banana waste and LOF-containing isolates of P-solubilizing bacteria improved plant height, the number of tillers, and N and P uptake by the plant. The rice grain yields among the treatments were not significantly different, but the highest rice grain yield (139.8 g/pot) was obtained at the treatment of the mixture of LOF-P isolate + LOF-banana waste (A2+A3 treatments). The 75% of the recommended dose of P fertilizer was not significantly different from 100% P fertilizer with LOF on growth and yield upland rice and nutrient uptake by the plant.

Abstract

Chemical composition of canna and arrowroot flour and starch cultivated in genetic resources garden collection in Natar, South Lampung. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 929-936. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).This study aimed to determine the chemical composition of flour and starch made from canna tubers and arrowroot tubers. Processing tubers into flour or starch provides opportunities for wider utilization and longer storage. The tuber flour was processed using the dry method while the tuber starch was processed using the wet method. Characterization of chemical composition includes proximate analysis consisting of moisture content, ash content, crude fiber, protein, fat and carbohydrates as well as whiteness. The fat and protein content of canna tuber flour (0.93% and 2.30%) and arrowroot (0.59% and 3.50%) were slightly higher than the fat content of canna tuber starch (0.89% and 1, respectively). 2%) and arrowroot (0.39% and 1.26%). The yield and whiteness of canna and arrowroot flour and starch produced in this study were low.
