Abstract

Field experiments to study "Organic Fertilizer Dose Variations on Three Sweet Sorghum Varieties on Growth and Yield of Sorghum for Ethanol" aimed to 1). Examines the interaction between wide varieties of sweet sorghum with a dose of organic fertilizer. 2). Determine an appropriate dose of organic fertilizer for growing sweet sorghum. 3). Determine the sweet sorghum varieties in response to the dose of organic fertilizer. Research conducted at the Experimental station, Faculty of Agriculture UPN "Veteran" Yogyakarta; using a split plot design with three replications and Research Laboratory, Faculty of Agriculture UPN "Veteran" Yogyakarta. The main plots varieties were: V1: Patir-3, V2: Samurai-2, and V3: Mandau and as subplot were dose of organic fertilizer: D1 = 20 g / plant; D2 = 40 g / plant; and D3 = 60 g / plant. The results showed that: (1) There was interaction between varieties with a dose of organic fertilizer on sorghum stalks weighting parameter. Each of sweet sorghum varieties gave different looks on any given dose of organic fertilizer. (2) Treatment varieties showed real effect on plant height parameter 8 mst, leaf number 8 mst, panicle length, sorghum stalk length, weight of 100 seeds, sorghum stem juice volume and juice sweetness level.Keywords: fertilizers, sweet sorghum varieties, bioethanol

Abstract

Sorghum Sorghum bicolor L. Moench is a crop cereal grains which is included in Gramineae or grasses. In Indonesia, currently sorghum crop brings new opportunity to be developed as a food crop, feed and producing bioethanol. The study aims to examine the interaction between the type of sweet sorghum genotypes and arbuscular micorhize doses, approppriate micorhize dose and sweet sorghum response to micorhize treatment. The research was conducted through a field experiment with a split plot design with sorgum genotypes as the main plot consisting of three genotypes which is G1=HZ-30, G2=Mandau, G3=Patir 9, and G4=Patir 3. As the sub plot is the micorhize dose consisting of three doses namely: D1=0 g/plant, D2=5 g/plant, and D3=10 g/plant with three replications. Observation were made on growth parameters which are plant height, stem diameter, leaf area, root volume, root dry weight, dry weight of the canopy and the dry weight of the seeds per hectare. Yield parameters consist of: essay panicle length and dry weight of seeds per hectare. The data is then analyzed its variance at 5% level of significance, and to find out the differences between treatments Duncan’s Multiple Range Test was conducted at 5% level of significance. The result shows: 1. An interaction is found between the treatment of genotypes and micorhize doses to both vegetative and generative growth of sweet sorghum. 2. Micorhizal dose treatment has not significant affect on all generative growth of sweet sorghum genotypes. 3. HZ-30 genotype with no micorhizal treatment produces the heaviest dry weight of seeds per hectare.Keywords: growth, arbuscular micorhize, genotype, yields.
