Abstract

ABSTRACTIndonesia is one of the largest wheat importers. Suitable environmental condition for wheat needs to be studied if wheat is going to be widely cultivated in Indonesia. The adaptability of wheat grown in various climates and altitudes is one of the important aspects. The objective of this experiment was to study the quantitative and morphological character of wheat grown in middle land (540 m asl) in Bogor, West Java. The experiment was arranged in randomized complete block design with three replications. Wheat genotypes used were three national varieties (Nias, Selayar, and Dewata), four new improved varieties (Guri 3 Agritan, Guri 4 Agritan, Guri 5 Agritan, and Guri 6 Unand), and one introduced genotype (SBD). Data were collected for several quantitative variables and seventeen morphological characters based on UPOV descriptor. The result showed that wheat growth was restricted in Bogor. Genotype determined plant height, leaf number, ear length, root length, number of spikelet, harvest time, seed weight, number of tillers, and plant biomass. Based on ear length, grain weight, and plant biomass, Guri 3 Agritan had the highest production than the other genotypes.Keywords: diversity, genetic relationship, high temperature, introduced genotype, phylogenetic

Abstract

ABSTRACTBambara groundnut can be cultivated in marginal land, however, its productivity is still low. In order to increase productivity, high quality seed must be used. The objective of the experiment was to evaluate the effects of seed invigoration using matriconditioning plus Rhizobium sp. and fungicide and reduction of N fertilizer on plant growth, yield, and quality of bambara groundnut seed. The experiment was conducted at Experimental Station in Cikarawang, green house in Cikabayan, and Seed Health Laboratory, Bogor Agricultural University from June 2013 until March 2014. This experiment was arranged in a split plot design according to completely randomized block design. The first factor was N fertilizer. Four levels of N fertilizer used were 0, 15.35, 30.7, 46.04, and 61.39 kg N ha-1. The second factor was seed invigoration. Seed invigoration consisted of without invigoration treatment (untreated), matriconditioning plus Rhizobium sp. and fungicide, matriconditioning plus Rhizobium sp., and matriconditioning plus fungicide. Result of the experiment indicated that matriconditoning plus Rhizobium sp. and fungicide improved plant growth (number of leaves, number of stem, nodule dry weight, root dry weight, and leaf dry weight), yield (weight of seed), and seed vigor (index of vigor). Matriconditioning plus Fungicide treatments significantly decreased the infection level of diseases on seed. Fertilizer application at the rate of 30.7 kg N ha-1 (half of optimum dose) was recommended because it showed the best result in pod fresh weight and dry weight, and seed weight.Keywords: benomyl, fertilization, fungicide, matriconditioning, Rhizobium sp.

Abstract

ABSTRACTMelon (Cucumis melo L.) is a high economic value horticultural crop that is cultivated in some regions of Indonesia under fertilization management. Application of inorganic fertilizer continuously can reduce soil microbial abundance. One of the soil microbial that promote plant growth is arbuscular mycorrhizal fungi (AMF) and Azospirillum sp. The aim of this study was to analysed the effect of AMF and Azospirillum sp. in promoting growth and production of melon. The experiment was carried out in a greenhouse and was arranged in a completely randomized design with five replicates. Five treatments tested were: control, fertilized with NPK, inoculated with AMF, inoculated with Azospirillum sp., inoculated with AMF + Azospirillum sp. The results showed that the effect of AMF on root growth and shoot growth were similar to NPK fertilizer. Azospirillum sp. increased root growth. On the other side, the effect of Azospirillum sp. on shoot growth was similar to NPK fertilizer. However, AMF and Azospirillum sp. inoculation solely increased plant height, fruit weight, fruit diameter, flavor and length of fruit storage. Meanwhile, combination of AMF and Azospirillum sp. increased plant height, root growth, shoot growth, fruit weight, fruit diameter, flavor and length of fruit storage. This study revealed that application of AMF and Azospirillum sp. in melon cultivation was more effective and efficient than NPK fertilizer.Keywords: arbuscular mycorrhizal fungi, Azospirillum sp., Cucumis melo L.

Abstract

ABSTRACTSugarcane cultivars tolerant to drought stress are needed for specific location. In vitro selection can be used to obtain plants tolerant to drought stress through regeneration of callus in the culture medium. The purpose of this study was to obtain regenerants from irradiated callus on the stress medium. The experimental design was a completely randomized design with two factors. The first factor was the regeneration medium (RG) added with PEG 6000, i.e., 0%, 5%, 10% and 15%, while the second factor was the dose of gamma ray irradiation i.e. 0 krad, 5 and 10 krad, and 15 krad. There were 12 treatments, each treatment was repeated 18 times and each repetition was a culture bottles planted with three clums of callus 10 mm diameter. RG medium was the MS medium added with 0.5 mg L-1 BAP, Kinetin 0.1 mg L-1 and IBA 1.0 mg L-1. The higher the concentration of PEG, the less regenerants were produced. Regenerants could be generated from the selection medium PEG up to 15%. Several shoots still produced from callus irradiated with 10 krad. Selection medium with PEG up to 10% decreased the precentage of albino regenerants. The gamma ray irradiation dose and the concentration of PEG significanly affected the number of  roots produced.Keywords: drought tolerant, in vitro, polyethylene glycol, plantlets, albino

Abstract

ABSTRACTThe use of high quality seed is one of the key factors to improve productivity. Probiotic bacteria has been used to increase plant growth and to control pathogens. The objective of the research was to evaluate methods of chili seed production that yielded high physiological and pathological quality using probiotic fluorescent bacteria Pseudomonas (P24). The bacteria was expected to function as plant growth promoting bacteria as well as capable of controling seedborne pathogen Colletotrichum acutatum causes antrachnose. The experiment was conducted during March until October 2014 in Seed Health Laboratory, Plant Bacteriology Laboratory, and Leuwikopo experimental garden, IPB. The experiment was arranged in a split plot randomized complete block design with three replications. The main plots were untreated and inoculation of C. acutatum. The subplot was six treatments of fluorescent Pseudomonas (P24) application. The results showed that matriconditioning and spraying of fluorescent Pseudomonas (P24) on nursery decreased disease incidence significantly. Matriconditioning and spraying of fluorescent Pseudomonas (P24) on nursery and flowering phase increased number of healthy fruit and total weight of seeds per plant significantly. These applications also increased seed physiological  quality indicated by germination percentage (GP) 77.04%, growth rate (GR) 9.72% etmal-1, vigor index (VI) 29.74%, and seed health by suppresed C. acutatum infection up to 12.25%.Keywords: anthracnose, Colletotrichum acutatum, control, matriconditioning, spraying
