Abstract

Taro (Colocasia esculenta L. Schott) is a plant that has an excellent economic and healthy value, as well as a great potential development of Bengkulu coastal area. That is because taro has wide adaptability, and can be consumed both as a staple food and healthy food alternative. This research was conducted to study the vegetative growth of two cultivars of taro given four different doses of nitrogen. This study applied a Randomized Complete Block Design (RCBD) with two factors. The first factor was the cultivar of taro consisted of two levels, namely Taro Satoimo (T1) and the Taro Local (T2). The second factor was the doses of nitrogen fertilizer which consisted of four levels namely: N0 = 0 kg / ha (control), N1 = 50 kg / ha (2.6 g, N2 = 100 kg / ha, and N3 = 150 kg / ha. Thus, obtained eight treatment combinations. Each treatment was repeated three times to get 24 plots. The results showed that based on increased vegetative growth, the cultivar Satoimo has a faster response than local cultivar. Satoimo has demonstrated another advantage because it produced some leaves and number new shoot. The best dose of nitrogen fertilizer on the vegetative growth of taro in the coastal area of Bengkulu is 150 kg/ha.

Abstract

Development of high yielding and superior cultivars requires information on characteristic of germplasm will be used. Ten curly-type hot pepper genotypes was grown in a completely randomized design with three replication in a low altitude land to determine their morphological characters and to evaluate genetic relationship among them based on their morphological similarities. The study was conducted in September 2015 until January 2016 in Medan Baru experimental station of Faculty of Agriculture, 15 m above sea level.  Observation was conducted on both quantitative and qualitative characters.  The results showed that there were not significantly diferent (?=5%) for plant habitus, leaf shape, leaf tip, leaf edge, leaf shape and seed shape.  Whereas for quantitative variables of stem diameter, number of fruits per plants and fruit length were significantly different, while for the other variables were not.  Cluster analysis with phylogenetic trees in 58% similarity coefficient resulted that the genotypes grouped in to six groups.  Group I consisted of genotype LPK and Ferosa, group II Mario, group III was genotype Laris, group IV consisted of genotype Kopay and Romario, group V KH and L Curup, and group VI included genotype Bogota and Sempurna. The Kopay and Romario genotypes have the closest relationship level of 73%, while Local Payakumbuh and Lokal Curup have the farrest relationship with the coefficient of 35%. From the results of the study it can be concluded that Local Payakumbuh and Local genotypes Curup can be used as parents with the highest probability to have high transgresive segregation or highest hybrid vigor. Keywords: morphological characterization, genetic relationship, curly hot pepper

Abstract

       Guava (Psidium guajava L.) is a plant whose fruit is very popular in Indonesia because it contains high vitamin C and its leaves can be used as herbal medicine. Orchard expansion of selected cultivars and fruit production of guava can be achieved vegetatively through  propagation by using mini-cuttings with the use of Indole Butyric Acids (IBA). A study was conducted to compare rooting success of mini-cuttings of herbaceous stem of four guava cultivars with IBA treatment. Four guava cultivars tested were Bengkulu Round, Getas, Crystal, and Bangkok.  Mini-cuttings were immersed in IBA solution at 0 ppm or 1000 ppm. Cultivar and IBA treatments were arranged factorially in a randomized complete  block design with  3 replications, each consisting of 25 cuttings. Variables observed included percentage of original-leaf shedding, percentage of emerging shoots, percentage of sprouting cuttings, new leaf number, root number, root length, and percent of rooted cuttings. The results demonstrated that cultivars affected rooting percentage, sprouted percentage, percentage of original-leaf fall, and number of root.  Getas had highest rooting and sprouting percentages, and showed lowest number of  original-leaf shedding; whereas, Bangkok demostrated greatest number of root.  IBA treatment increased the number of root and the number of original-leaf shedding, but reducing rooting percentage of mini-cutting. There was no interaction between cultivar and IBA teratment.
