Abstract

The availability of drought-tolerant maize inbred materials are useful to develop a hybrid or synthetic drought tolerant maize varieties. This research was aimed to select drought tolerant and determine secondary traits for selection of inbred maize. Selection of 31 maize inbred lines was conducted in nested experimental design in which the replicate was nested into the drought stress selection condition and normal irrigation. Drought stress treatment was applied during flowering to milk phase. In the normal irrigation condition the water was supplied every 10 days. The results showed that the medium tolerant to tolerant to drought stress inbred lines were 1044-30, DTPYC9-F46-3-9-1-1-B, CML161 / NEI9008, DTPYC9-F46-1-2-1-2- B, and Mr14. The yield declined of tolerant/medium tolerant inbred lines of about 17.0-38.3% was lower than sensitive inbred lines of about 42.8-70.7% under stress condition. The tolerant/medium tolerant inbred lines can be used for developing drought tolerant or synthetic varieties. The secondary traits effective for selection of drought tolerant inbred lines were shelling percentage, leaf chlorophyll, leaf rolling scores, number of tassel, the female flowering dates, and anthesis silking interval (ASI). The traits were more effected by genetic factors than the environmental factors and correlated to yield under drought stress conditions.Keywords: anthesis silking interval, environmental condition, inbred lines, tassel number, yield

Abstract

Excessive shading during plant growth is one of the factors that might decrease the productivity of crops. The aim of this study was to determine agronomic characters of soybean germplasms grown under shaded environment. The research was carried out at Kendalpayak experimental station (grey Alluvial soil, 450 m above the sea level with C3 climate type) during dry season in Malang, from February to April 2006. The experimental design used was Randomized Complete Block Design with three replications. The genetic material observed were 120 accessions of Balitkabi’s soybean germplasm; the treatments were without shading and 50% shading using shading net. The results showed that 50% shading decreased plant age to harvest, increased plant height, and reduced the number of pods and seed weight compared to those in no shading environment. Based on Stress Tolerancy Index (STI) analysis on the seed weight per plant, fi ve accessions i.e. MLGG 0845, MLGG 3335, MLGG 0010, MLGG 0771, and Wilis demonstrated high tolerance on 50% shade

Abstract

The objective of this study was to investigate the effect of photoperiod, indole acetic acid (IAA), and phosphorus on soybean plant growth and seed quality during storage. The trial was carried out at Sebapo Experimental Station, Jambi, Center for Post Harvest Research and Development, The Ministry of Agriculture and Center for Forest Research and Development, The Ministry of Forestry, Bogor from November 2009 until June 2010. Split-split plot design was used consisted of three factors, i.e. photoperiods (12 and 14 hours 54 minutes) as the main plot, concentrations of IAA (0, 75, and 150 ppm) as subplot, and dosages of phosphorus (0, 60, and 120 kg P2O5 ha-1) as subplot. The result showed that photoperiod, IAA, and phosphorus application had significantly improved production and seed quality. The path analysis showed that the weight of 1,000 seeds affected other variables. The seed protein content has the largest path coefficient compared to other variables. The treatment of mother plant with 14 hours 54 minutes photoperiod combined with IAA of 150 ppm and P2O5 of 120 kg ha-1 resulted in the highest seed quality during 90 days of storage in room temperature.

Abstract

The research was conducted to study the effect of repellent plants and seed treatments on growth and production of organically grown vegetable soybean. The experiment was carried out at Cikarawang Research Station, Bogor, from September 2005 to May 2006. The organic experiment was arranged in a split plot design using four species of companion plants as repellent plants, i.e. Tagetes erecta, Cymbopogon nardus, Ocimum gratissimum, Tephrosia vogelii, and without repellent plants as the main plot, and seed treatments i.e. galangal oil, Pseudomonas fluorescens, and without seed treatments as sub plot using 3 replications and conventional system (using pesticides) as control. Plants grown under conventional system had a greater fresh pod weight (6.7 kg. 10 m-2) than those in organic system (4.80-5.79 kg. 10 m-2), a lower insect infestation (19.17, 22.92 and 32.50%) and disease prevalence (9.17, 11.42 and 14.42%), at 6, 7 and 8 Week After Planting (WAP) respectively, than the organic system. In the organic experiment, the use of O. gratissimum as repellent plants resulted in a significantly lowest empty pod per plant (0.79 g). T. erecta and O. gratissimum without seed treatment, P. fluorescens without repellent plants, and T. vogelii with galangal oil seed treatment has the significant lowest insect infestation at 6 WAP of 20.67, 23.00, 26.67 and 27.33%, respectively. An organic system using repellent plants had a significantly lower insect infestation at 8 WAP (35.67-40.33%, O. gratissimum being the lowest) than without repellent plants (50.56%). Seed treatments on organic system had the lower disease prevalence at 8 WAP (33.87% on P. fluorescens and 35.47% on galangal oil) than without seed treatments (37.73%). Number of root nodules (11.6-16.7 to 7.8) and root nodules dry weight (0.068- 0.101 to 0.040 g) of the organic system were greater than the conventional system. Soybean without repellent plants had a greater number of harvestable plants (137.3), but it was fewer than the conventional system (158.3)

Abstract

National demand on soybean can be full filled by extending production area including marginal lands. Tidal swamp is one of marginal lands which potentially can be cultivated for soybean production with the use of tolerant varieties to waterlogging. So far, there are only two varieties that are tolerant to tidal swamp condition. This research was conducted to study the response of soybean genotypes to waterlogging and to provide gene resources in breeding for tidal tolerant variety. The research was conducted from October 2007 to February 2008 in the glasshouse of Indonesian Legume and Tuber Crops Research Institute (ILETRI), Malang. The experimental design was split-plot with two replications; where the main plot was waterlogging treatment and the sub plot was soybean genotype (17 genotypes of ILETRI collection). The results showed that soybean genotypes had different responses to different water treatments, shown on the number of branches and reproductive nodes, the number of filled and unfilled pods, and yield (dry seeds) per plant. Waterlogging inhibited plant growth of all traits. Under waterlogging, the highest number of reproductive nodes and filled pods, and yield per plant was from MLGG 0537 i.e. 12.25, 19.25, and 3.13 g plant-1, respectively.

Abstract

Phosphate defi ciency is one of the main constraints to increase soybean yield in acid mineral soil. An experiment was conducted with an objective to discover scientifi c base of fertilizer selection based on soybean adaptation mechanism to mitigate P defi ciency in acid mineral soils in Bengkulu Province. A factorial experiment was arranged in a randomized complete block design with four replications. The fi rst factor was soybean genotypes, i.e. Slamet and three new soybean genotypes (NSGs) i.e. 19BE, 25EC and 13ED, and second factor was P fertilization dosages (0 and 400 mg P2O5 kg-1 soil). Soybean was grown in a greenhouse using double pot system. Research results showed that the NSGs had different mechanism in P uptake from soil with high P absorbing capacity compared to Slamet genotype. NSGs translocated more carbon to root, and decreasing of shoot-root ratio, about 66-70%. NSGs 25EC produce more oxalic and malic acid, and 13ED produce more citric acid to obtain same amount of P absorbed by Slamet variety. Under low P, NSGs developed symbioses with mycorrhizal arbuscular fungus, however, only 19BE which increase microbe population in rhizosfer. Phosphosrus fertilization supressed arbuscular mycorrhizal fungus development (15-100%), alkaline phosphatase activity (20-88%), and microbial C biomass (40-71%) in rhizosphere of new soybean genotypes

Abstract

Chili pepper (Capsicum annuum L.) was grown with polyethylene mulched on Inceptisol soil with low pH (5.5), low organic-C (1.54%), very low total N (0.12%), low K content (0.29 me (100 g)-1), but very high soil P2O5 concentration (19.2 ppm) to evaluate the best crop management practices with starter solution. Seven starter solution combinations (1 = No Starter Solution + No CM + No SI, 2 = CM + SSVC, 3 = CM + SSG, 4 = SI + SSVC, 5 = SI + SSG, 6 = SI + CM+ SSVC, and 7 = SI + CM + SSG) were arranged in a randomized completely block design with four replications. Whereas CM = cow manure, SSVC = organic starter solution, SSG = inorganic starter solution, and SI=standard inorganic fertilizer. The results showed that inorganic, as well as organic, starter solution increased chili pepper growth and yield in less fertile soil. The highest marketable yield was obtained with application of standard inorganic (SI) + cow manure (CM) + inorganic starter solution (SSG). Inorganic starter solution application resulted in a better plant growth than organic starter solution, being evident at 1 week until 7 weeks after transplanting. However, inorganic starter solution did not signifi cantly increase total marketable yields. Application of cow manure, standard inorganic fertilizer, or addition of organic starter solution reduced total unmarketable yield, improved fruit qualities and increased marketable yield

Abstract

The purpose of the research was to examine the pollen germination process and growth rate of pollen tubes of papaya. Pollen tube growth of nine genotypes of papaya (IPB 1, IPB 2, IPB 3, IPB 4, IPB 5, IPB 7, IPB 8, IPB 9, and IPB 10) was investigated in this experiment in order to study their pollen germination rate and pollen viability. The fresh pollen were excised from the fl owers of papaya grown at Tajur Field Station of Research Center for Tropical Fruit, Bogor Agricultural University (IPB), Bogor. The extracted pollen was cultured aseptically on the Brewbaker and Kwack medium (pH 7.3) at ambient temperature of 26-28 °C. Pollen germination and pollen tube growth was observed under optical microscope with 100 and 400 magnifi cation. Papaya pollen viability was not associated with size-based categories of papaya fruits. IPB 4 had the longest pollen tube at fi rst 30 minutes after germination (115.5 µm), whereas IPB 10 had the shortest (99.5 µm). The distance from stigma to ovary in hermaphrodite fl owers varies with genotypes, ranging from 7.38 to 13.44 mm. Average length of pollen tube within four hours of germination for small papaya fruit category (IPB 1, IPB 3, and IPB 4) was 1,030.67 ± 19.14 μm, while the distance between stigma and ovary was short (14.85 ± 2.19 mm) so that the expected of fertilization process occurred sooner. At the end of the experiment (four hours after germination), IPB 1 genotype had the longest pollen tube (1,052 µm) while IPB 9 genotype (913 µm) had the shortest pollen tube. Genotype with the highest percentage of germination at the end experiment was IPB 2 (65.65%), whereas the lowest was IPB 7 (42.56%).

Abstract

Gamboge is the main problem in mangosteen agribusiness because it is one of the major factors lowering fruit quality. Calcium is one of the important elements that strengthening cell wall; it is which was binding with the pectin as a middle lamella component. The objectives of the research were to study the effect of calcium application on the presence of gamboge spots, physical, and chemical properties of mangosteen fruit. Trial was conducted in a randomized complete block design with three replications in two consecutive years. The calcium source was dolomite, applied in four different dosages, i.e. 0, 18, 24, and 34 ton ha-1 for the fi rst year and 0, 12.5, 15, and 17.5 ton ha-1 for the second year. The results showed that calcium application raised soil pH and calcium content of the soil, exocarp and mangosteen leaves. Dolomite applications using 18 and 24 ton ha-1 in the fi rst year and 17.5 ton ha-1 in the second year were effective to reduce gamboge spots on the outer part of fruit, however they were not effective to reduce gamboge in aril. Dolomite applications did not increase transversal diameter, fruit weight, total soluble solids, total titratable acids, and ratio of total soluble solids with total titratable acids of the fruits.
