Abstract

Sugarcane (Sacharum officinarum L.) is a sugar-producing plant and is a food commodity that is needed by the people of Indonesia. National sugar demands are increasing every year. The low productivity of sugarcane is due to the competition of weeds which can reduce sugarcane production. To achieve high productivity, it is necessary to pay attention to the varieties used because they require certain conditions in their management. The purpose of this study was to determine the effect of varieties and types of weeds on the initial growth of sugarcane. The study was conducted from September 2018 to December 2018. The study used factorial Randomized Block Design (RBD) with two factors and four replications. The first factor consists of 4 sugarcane varieties, namely: Bululawang (V1), Red HW (V2), VMC (V3) and PS 862 (V4). The second factor type of weed consists of 2 types, namely Cyperus rotundus (N1) and Amaranthus spinosus L. (N2). The results showed that (1) There was interaction between the varieties (V) and the weed types (N) in stem diameter parameters and number of tillers, the treatment V4N1 gives the best response to stem diameter 1,31 cm and 4,25 number of tillers; (2) The treatment of varieties (V) gives affects to stem diameter and number of leaves, the treatment V4 gives the best response 5,38 to number of leaves; (3) Types of thorn spinach weeds can reduce the initial growth of sugarcane.

Abstract

Robusta coffee is a type of coffee that can be cultivated vegetatively. Grafting cuttings technique is one of the propagarion techniques commonly used in Indonesia. The use of auxin and cytokinin hormones can be used in the coffee seedling phase to support the growth of coffee plants. The puspose of this study was to determine the effect of auxin and cytokinin hormones on the growth of robusta coffee seedling in the cuttings grafting method. The method use was a factorial completely randomized design with 2 factors. Factor 1 is the concentration of auxin hormones consisting of 3 levels, namely A1 (0 ppm), A2 (50 ppm), and A3 (100 ppm). Factor 2 consentration of cytokinin hormone which consists of 3 levels namely S1 (0 ppm), S2 (50 ppm), and S3 (100 ppm). The result were analysed using ANOVA and further test using Duncan Multiple Ranage Test (DMRT). The parameters observed were the percentage of cuttings success, number of leaves, number of shoots, shoot height, shoot diameter, chlorophyll content. The result showed that the provision of 50 ppm auxin and 50 ppm cytokinin had the best trend in the variable number of leaves, shoot diameter and shoot height.
