Abstract

Dioscorea is potentially used as staple food to support food security. The research was aimed to determine the effect of stake length and time of  stem twining  on  the growth of Dioscorea sansibarensis Pax. The experiment was conducted  in  Purwodadi Botanic Garden from December 2014 until May 2015 using split plot randomized block design consisted of two factors, i.e. the stake length and time of stem twining. The stake length was the main plot consisted of 150 cm, 100 cm and 50 cm above soil surface and without stake (control). The time of stem twining as subplots, i.e. stem twined early, twined at the time of 4 leaves stage, and twined at 8 leaves stage. Each combination of the treatments was replicated three times. The results showed that there was significant effect on the stake length  and the time of stem twining treatments on the plant growth and yield. The stake  length of 150 cm treatment produced the highest fresh tuber and total plant dry weight, i.e., 257.24 g and 132.77 g per plant, respectively. On the contrary, the plant without stake produced the lowest fresh tuber and  total dry weight of plant, i.e., 112.10 g and 48.65 g per plant, respectively.Keywords: biomass,leaf area, photosyntesis, tuber weight

Abstract

ABSTRACT Sorghum is one of the potential foods with a higher protein content than rice. Sorghum seeds can be milled and cooked as sorghum rice. This study was aimed to obtain information on the inheritance of morphological and agronomic characters from the population derived from crosses of wide genetic background. The study consisted of the formation of F1 population and evaluation of morphological and agronomic characters in the segregated population (F2) of the three selected F1 genotypes. The location of the research was at IPB Experimental Field, Leuwikopo. The performance of the F1 genotypes were between the two parents, except for the yield components of PI-150-20-A x Numbu and PI-150-20-A x Kawali were higher than the parental lines. The performance of the F2 generation population was also between the parental lines, but with a wider distribution. The sorghum seed color is controlled not only by additive and dominant gene action, but also by epistatic gene action. The character of seed weight per panicle is controlled by epistatic gene action. In the F2 population of the crosses of PI-150-20-A x Numbu and PI-150-20-A x Kawali and PI-10-90-A x Numbu, the seed weight character is inherited with moderate heritability value. Based on genes action dan heritability, bulk or single seed descent method are suitable for yield improvement of the populations.Keywords: gene action, heritability, seed color, segregation, sorghum

Abstract

ABSTRACTInformation on combining ability and heterosis are desirable to determine the best parents in chili pepper hybrid variety development. To estimate general and specific combining abilities and  heterobeltiosis of backcross lines selected for CMV tolerance, eight selected lines were crossed to three CMV tolerant lines in a Line x Tester method and the crosses were evaluated in a CMV inoculated condition. The results showed that general and specific combining abilities varied tremendously among crosses and traits. Generally, specific combining ability (sca) variances were higher than general combining ability (gca) variance indicating that interaction of non-aditive predominance the inheritance of traits under study. Amongs lines evaluated, there was no a general combiner line for vegetative growth. However, lines S1B3A-29-13-47 and S1B3B-12-13-2 were the best general combiner for a breeding program to improve total number of fruits and fruit weight per plant, respectively. Crosses of S1B3C-16-22-34 x C1042, S1B3B-49-40-6 x C1043, and S1B3C-34-18-9 x C1042 were consedered the most prospective crosses as indicated by high value of sca, i.e., 130.53, 102.01 and 61.93, with heterobeltiosis estimate of 146.06, 26.05 and 24.31, respectively.Keywords: capsicum annuum, heterobeltiosis, GCA, SCA

Abstract

Sugarcane and replanting programs require a lot of seed cane and can not be fulfilled from  budsetts. To fill  up the gap the use of budchip seedlings  is suggested. The appropriate planting arrangement for budchip seedling has not been studied thoroughly. The study was conducted at the Asembagus Experimental Station, Situbondo, East Java, from January to December 2014 for the plant cane (PC) and from January to December 2015  for ratoon  cane (RC). Research was arranged in a randomized block design with three replications. The treatments consisted of (1) single budsett in single row planting, (2) double budsetts in double rows planting, (3) single budchip in single row planting, (4) single budchip in double rows planting, and (5) double budchips in double rows planting. The results showed the budchip seedling increase productivity 14.46-15.46%, sugar yield 18.17-23.38%, and profit 873% from budsett seedling. Double rows planting with budchip seedling increase productivity 52.11-61.01%, sugar yield 48.51-61.84%, and profit 603%  from single row planting. Double rows planting suitable for budchip seedling is  single budchip with productivity 52.53-88.30 ton ha-1, sugar yield 3.69-8.17 ton ha-1 and profit IDR 9,123,000 ha-1 per year.

Abstract

ABSTRACTThis experiment is a further development of several previous studies on the potential of Bacillus subtilis 5/B and Pseudomonas diminuta A6 (rhizobacteria), and Aeromonas sp. F112 (phyllobacteria) as biological agents. Research aimed to evaluate the application of biological agents to promote plant growth and to control bacterial leaf blight (BLB) disease in rice seed production. This research consisted of two experiments, the first was in the nursery while the second was in the field. The first experiment conducted in a completely randomized  design with one factor (seed treatments) and three levels, i.e., control (untreated), matriconditioning + streptomycin sulphate 0.2% (BsM), biomatriconditioning + B. subtilis 5/B + P. diminuta A6 (BM). The second experiment was conducted in a randomized complete block design with one factor (biological agent aplication methods) and nine levels, i.e., control (untreated), matriconditioning +  streptomycin sulphate 0.2% (BsM), biomatriconditioning + B. subtilis 5/B + P. diminuta A6 (BM), soaking of seedlings root with  B. subtilis 5/B + P. diminuta A6 (RA), foliar spraying with Aeromonas sp. F112 (SD), BM + RA, BM + SD, RA + SD, BM + RA+ SD. The result showed that seed treatments significantly increased field emergence. Eventhough all treatments did not significantly affect plant growth, incidency and severity level of BLB disease, and yield components, biomatriconditioning showed a better improvement in yield components. The seeds produced from plants treated with the biological agents showed significantly higher vigor index than untreated and matriconditioning + streptomycin sulphate 0.2%.

Abstract

Sorghum (Sorghum bicolor L. Moench) is prospective crop for food as well as feed and bioenergy. It adapts to wide agroclimate and agroecology. However, the productivity is accounted low in Indonesia. Low productivity of sorghum can be enhanced through intensification, e.g., precise dose of nitrogen and phosphorus fertilizers application. The aim of this research was to determine the optimum dose of nitrogen and phosphorus fertilizers to maximize growth and yield of sorghum in latosol soil, in order to develop fertilizer recommendation on specific soil type. The research was conducted at Cikarawang, Bogor from March to July 2015. Nitrogen and phosphorus fertilizers were arranged and applied simultaneously using randomized completely block design with three replications. Nitrogen fertilizer was applied in five levels, i.e., 0, 60, 120, 180, 240 kg N ha-1 and phosphorus levels were 0, 18, 36, 54, 72 kg P2O5 ha-1. Results showed that the application of nitrogen and phosphorus fertilizers significantly increased vegetative growth and yield components. The optimum dose were 161 kg N ha-1 (133.7%) and 43 kg P2O5 ha-1 (121.5%) for latosol soil.Keywords: fertilizer, optimum dose, soil type, vegetative, yield component

Abstract

Area of ratoon cane (RC) in Indonesia is more than 75% of total area of cane with productivity lower than plant cane (PC). To improve the productivity proper fertilizer application is required in accordance with the planting system used. This study was aimed to acquire a package of NPK compound fertilizer efficient for several planting systems of ratoon cane. The experiment was conducted in Muktiharjo Research Station, Pati in October 2013-September 2014. Two packages of compound fertilizer, i.e. 15N:15P:15K:10S formula package (500 kg compound fertilizer + 600 kg ZA ha-1) and 16N:8P:18K:2S:2Si formula package (500 kg compound fertilizer + 100 kg ZA ha-1) were arranged in randomized block design with four replications. Both packages were applied to two single row planting systems and two double row planting systems. The results showed that in single row planting system with both center - to - center (ctc) distances, i.e. 130 and 110 cm, the application of 16N:8P:18K:2S:2Si formula package resulted productivity, sugar content, and sugar yield that are no different from those with 15N:15P:15K:10S formula package. However, in double row planting systems with ctc 50/170 cm, 16N:8P:18K:2S:2Si formula package increased 9.20% sugar yield. The profit from 16N:8P:18K:2S:2Si formula package (12.07 million-14.23 million rupiah ha-1) in single row planting systems were lower than that of 15N:15P:15K:10S formula package (13.15 million-15.15 million rupiah ha-1). However in double row planting systems with ctc 50/170 cm, 16N:8P:18K:2S:2Si formula package produces profits (39.92 million rupiah ha-1) higher than with 15N:15P:15K:10S formula package (28.49 million rupiah ha-1).Keywords: planting-system, productivity, sugar-content, sugar-yield

Abstract

The genetic transformation via pollen-tube pathway is an alternative method to overcome the constraints imposed by genotype specificity in transformation and regeneration in jatropha (Jatropha curcas L.) tissue culture. Therefore, it is necessary to establish important parameters for efficient genetic transformation of jatropha via pollen-tube pathway. The objective of the research was to study the efficiency of direct transformation of jatropha via pollen-tube pathway based on histochemical and molecular analysis. Solution of purified pCAMBIA1301 DNA plasmid carrying a hptII marker gene and a gus reporter gene with concentration level of 0.05, 0.25, 0.50 µg µl-1 were applied to stigma of flowers at 1, 2, 4, 7, 10 h after pollination. Seedling of IP3A, IP3P and JcUMM18 jatropha’s genotypes derived from 15 combination treatments of plasmid DNA concentration and application time, also wild type was subjected to histochemical and molecular analyses. Based on those analyses, the efficiency of transformation via pollen-tube pathway of three jatropha genotypes ranged from 1.5-16.7%. PCR analysis showed that a number of positive plants were identified by using specific primers hptII and gus, i.e. 1-3 and 3-7 plants of the 15 combined treatments, respectively. It indicated that the transformation efficiency via the pollen-tube pathway varied in each jatropha genotype.Keywords: Jatropha curcas L., pCAMBIA1301, plasmid DNA, stigma-drip
