Abstract

Indonesia has extensive acid soil but its utility is still limited because of its low nutrient content. Jatropha is a plant which can grow on various soil types, includes on marginal one, and has used as raw material for biodiesel. Therefore, the growth of jatropha on acid soil need to be studied as an effort for developing jatropha and utility of acid soil in Indonesia. To initiate the effort, research to grow various jatropha genotypes on acid soil was done. The objectives of this research was to obtain a potential tolerant jatropha genotype for acid soil. The research was conducted at UPTD Development of Dryland Technology at Singabraja Village, Tenjo Subdistrict, Bogor, West Java, from November 2010 ? August 2011. This research using Randomized Complete Block Design (RCBD) with jatropha genotype as factor. The result showed that there were differences in growth among the jatropha genotypes. There are five jatropha genotypes with better growth in acid soil (pH 5.0) compare to others, i.e. Medan I-5-1, Dompu, IP-2P-3-4-1, Sulawesi, and Bima M.Keywords: physic nut, genotypes, Jatropha curcas, acid soil

Abstract

Increased productivity of maize can be done with the use of high quality seeds from improved varieties such as hybrid seed. The objectives of this study were Increasing productivity of maize female parent is important in order to reduce the price of hybrid seed. The objectives of this study were to determine the nitrogen fixing bacteria compatible with phosphate solubilizing bacteria (PSB), and using those bacteria to increase physiological seed quality and seedling growth of maize female parent. The research consisted of laboratory and field experiments. Laboratory experiment for the isolation and identification of rhizobacteria resulted in 25 Azotobacter and 29 Actinomycetes non-pathogenic isolates capable of fixing nitrogen and PSB selected for compatibility tests were AB3, B28, P12, P14, P24, and P31. The compatibility test showed 25 pairs of BPF with Azotobacter and 16 pairs of BPF with Actinomycetes were mutually compatible. The BPF pair with Azotobacter or Actinomycetes P24-AzL7, P24-AzL9, B28-AcCKB4, P24-AcCKB9, P24-AcCKB20, and P24-AcCKW5 were able to increase the vigor index of hybrid maize female parent seed. Field experiment was arranged in a split plot design with three replications. The main plot was dosage of N-P fertilizer (0%, 25%, 50%, 75%, and 100% of recommendation dosage), and the subplot was 12 rhizobacteria treatments selected from 25 compatible pairs of BPF with Azotobacter and 16 pairs of BPF with Actinomycetes and 1 control. The application of compatible pairs of bacteria had a significant effect on plant height, the number of leaves at 3 and 4 weeks after planting and plant dry weight. However, the best treatment i.e. B28-AcCKB4 was not significantly different with the nutrient broth treatment (as control).

Abstract

ABSTRACTThe recent scarcity of fuel has stimulated many efforts to remove dependence on petroleum oil by finding alternative sources of new and renewable energy. Jatropha curcas L. has been chosen as a source of biofuel that has an important role as a petroleum oil substitute, especially for producing biodiesel. Possible efforts for the development of Jatropha in Indonesia include exploration of Jatropha plants from various regions of Indonesia, introducing the plants from abroad and plant breeding. The purpose of this study was to study the genetic parameters of morpho-agronomic traits and selection of potential genotype for genetic improvement of Jatropha curcas. The experiment was conducted at the Biotech Center, BPPT from November 2011 to July 2012. The experiment was performed using a complete randomized block design with sixteen genotypes of J. curcas. Five plants were used for each genotype, with three replications. Results of this study showed that genetic diversity of the genotypes based on morpho-agronomic characters was relatively narrow, with genetic diversity coefficient ranged from 2.73% to 9.02%. The broad-sense heritability was high for all characters, ranged from 32.26% to 85.89%. None of morpho-agronomic characters observed in the 16 genotypes was directly correlated to productivity and seed oil content. Number of fruit and total seed number per bunch were the best characters for selection criteria to obtain high dry seed weight. Based on the bi-plot analysis on seed oil content and dry weight characters among the observed genotypes, LMP and CRP x PDI could be recommended as potential F1 parents to be used in constructing F2 population.Keywords: biplot analysis, broad-sense heritability, genetic diversity coefficient
