Abstract

[PHYSIOLGICAL PERFORMANCES AND YIELD OF GUINEA GRASS (Panicum maximum Jacq.) AS AFFECTED BY APPLICATIONS OF GYPSUM, MANURE, AND NITROGEN]. Agricultural production on saline soil is often hampered by the inherent soil properties that limit the plant to gain optimal growth and development. Objective of this study was to determine the effects of gypsum, manure, and nitrogen applications  on the physiological characteristics and yield of guinea grass. A factorial experiment was set up in a greenhouse, involving two levels of manure (0 and 20 ton ha-1), four levels of gypsum (0, 0.75, 1.5, and 3 ton ha-1), and three levels of nitrogen (0, 50 kg N ha-1 in form of nitrate, and 50 kg N ha-1 in form of ammonium). Application of manure at 20 ton ha-1 produced higher leaf area per plant (LAPP), photosynthetic rate, nitrogen uptake, relative growth rate (RGR), plant height, and forage and dry matter productions as compared to no manure. Similarly, LAPP, photosynthetic rate, and net assimilation rate (NAR) had increased linearly as the gypsum applications were increased from 0.75 to 3 ton ha-1. ANR were increased in quadratic fashion on both manure treatments in accordance with the increment of gypsum applications. LAPP, NAR, ANR, N uptake, plant height, RGR, and dry matter production were increased by application of either nitrate or ammonium application, whereas the highest forage production was found on combination of manure at 20 ton ha-1 and N at 50 kg ha-1 in form of ammonium.

Abstract

[THE EFFECTIVENESS OF Trichoderma sp. AND Gliocladium sp IN CONTROLLING FUSARIUM WILT ON CHRYSANTHEMUM]. Fusarium wilt is a major soil borne disease in chrysanthemum, which results in yellowing and permanent wilt on the plant. The disease has capability to remains intact in the soil for years so that preventive operation prior planting often fail to provide fusarium-free environment for the plant. The elaboration of use of antagonistic organisms as the biological agents may provide an effective solution for controlling the disease. Objective of this study was to evaluate the effectiveness of two species of fungi, Trichoderma sp. and Gliocladium sp.,  as the antagonistic agents for controlling the development of fusarium wilt on chrysanthemum. Both fungi were applied singly or in combination onto the fusarium inoculated soil which were prepared as growing media for chrysanthemum plants. Results indicated that Trichoderma sp. and Gliocladium sp. were effective in controlling the development of fusarium wilt in krisan, where application of  combined antagonistic agents had produced the highest suppression to the fusarium development (70.1 %), followed by single application of Trichoderma sp. (56.4 %) and Gliocladium sp. (55.9 %).

Abstract

[THE ISOLATION OFSteinernema FROM CORN FIELD AND ITS PATHOGENECITY TO Spodoptera litura F]. Insect pathogenic nematode (IPN) offers an environmentally sound of controlling insect pest, as alternative for chemical insecticide. This research was conducted to evaluate the effectiveness of  Steinernema sp isolates collected from corn fields in Southern parts of  Bengkulu Province. The factorial experiment involved treatment combinations between sources of IPN isolate (Seluma, South Bengkulu, and Kaur) and density of IPN isolate  (100, 200, and 400 JI mL-1). The pathogenecity of the isolates were tested by inoculating the isolates on 4th instar of S. litura. The isolate of IPN collected from Seluma and Kaur corn fields were more effective in controlling the insect compared to those of the South Bengkulu as S. litura was killed faster and caused the 100 % mortality at 60 hours after inoculation. The symptoms of attacked larvae of S. litura were sluggish movement, body color changed to blackish with damaged internal organs. (JI=juvenile infective)

Abstract

[EFICATION OF BOTANICAL INSECTICIDE OF Tephrosia vogelii Hook. f. LEAF EXTRACT AGAINTS Crocidolomia pavonana (F.) AND Plutella xylostella (L.) AND ITS EFFECT TO Diadegma semiclausum (Hellen)]. The active fraction of hexane extract of Tephrosia vogelii (Tv) leaves was evaluated for this insecticidal activity on second-instar larvae of Crocidolomia pavonana and Plutella xylostella as well as for the safety to the adults of Diadegma semiclausum parasitoid. Fraction (fr) 2-4 of Tv from column chromatography (CC) had strong insecticidal activity on C. pavonana and P. xylostella.  In the test with C. pavonana, the fraction was more active by feeding than by contact. Based on LC50 at 72 hours since treatment (HST), fr 2-4 CC Tv was 1.8 times more toxic to P. xylostella than to C. pavonana.  The fr 2-4 CC Tv showed strong antifeedant effect against C. pavonana larvae.  At equal test concentrations, the treatment with fr 2-4 CC Tv caused much lower mortality in D. semiclausum parasitoid adults than in its host larvae, P. xylostella.   In contrast, an organophosphate profenofos, included in this study as a positive control, was much more detrimental to D. semiclausum than to P. xylostella.  In the semifield experiment, fr 2-4 CC Tv had comparable effect with profenofos and bioinsecticide Bacillus thuringiensis in reducing the population of C. pavonana larvae on broccoli plants.

Abstract

[BOTANICAL SUPPRESSION ON CONTAMINATED TOMATO SOIL BY Fusarium oxysporum f.sp. lycopersici]. A screen house study was carried out to identify the best botanical materials and their application time on suppression of Fusarium oxysporum f.sp. lycopersici pathogen in contaminated soil and on the growth of tomato. A randomized block design with three replications was used allocate 19 treatment combinations of botanical materials (extract of neem leaves, clove leaves, teak bark, pine bark, and catalpha leaves) and time of applications (4, 2, or  4 and 2 weeks before planting).  Observations were made on the development of the pathogen, disease intensity, and plant growth. Results showed that all botanical materials used could reduce the pathogen population but not the plant growth components. Extract of clove leaves applied at 4 weeks before planting was the best in decreasing the pathogen population (79.22 %).

Abstract

[SOIL PROPERTIES DEVELOPED FROM VOLCANIC MATERIALS IN WEST HALMAHERA, NORTH MALUKU]. West Halmahera region is dominated by soils formed from young volcanic materials that have unique properties and high productivity for agricultural use. The purpose of this study is to characterize soil properties derived from volcanic materials in that area and to test the andic soil properties according to Soil Taxonomy 2006. Four pedons of strato volcanoes from the area were described their morphological properties in the field and 16 soil samples were analyzed for physical, chemical and mineralogical properties in the laboratory. The results indicated that all the pedons show black to very dark brown colored in A horizons and dark brown to brown in B horizons. The soils are deep, loam to sandy loam texture (sand content 38-71 %). The soils have weak to moderate subangular blocky structure and very friable consistency. The soils show slightly acid to neutral reaction (pHH2O 6.0-6.8), high pHNaF (10.78-10.95), high organic carbon (3.75-4.65 %) in A horizon, moderate to high cation exchange capacity and base saturation. All the pedons show high P-retentions (45-80 %), high values of ammonium oxalate extractable (Alo+0.5Feo) (2.91-6.070 %), high volcanic glass content (>5%), and index values of [(Alo+0,5Feo) x 15,625+ (%volcanic glass)] > 36.25 that meet the requirements for andic soil properties, and thus they are classified as Andisols order. The sand minerals are dominated by volcanic glasses and dark minerals that belong to intermediary properties, and high weatherable mineral reserve.

Abstract

[ELIMINATION OF Pineapple Mealybug Wilt-associated Virus (PMWaV) FROM PINEAPPLE PLANT BY HOT WATER TREATMENT]. Mealybug wilt of pineapple (MWP) is a devastating disease found in all the major pineapple growing regions. Closterovirus particles can be detected in both MWP symptomatic and asymptomatic pineapple. Rogue of symptomatic plants is the simplest method of controlling MWP disease, but this method is less effective as PMWaV might remains at asymptomatic plants. Use of pesticide to control mealybug and ants is not efficient and high cost. The research was conducted to develop elimination method for PMWaV-free plant by hot water treatment. PMWaV infected plant parts (leave, stem, crown) were exposed to two hot water treatments, consisting of 35 ºC for 24 hour as pre-treatment and immediately followed by hot water treatment either 56 ºC for 60 minute or 58 ºC for 40 minute in a water bath. The infected plant without hot water treatment served as the positive control, and healthy plant without hot water treatment as the negative control. PMWaV infection could be eliminated from propagative material through hot water treatment 58 ºC 40 minute in a water bath without decrease propagative material viability.

Abstract

[THE PRODUCTIVITY OF LOWLAND RICE UNDER DIFFERENT POPULATION DENSITIES]. Population density will determine the crop productivity on either individual plant basis or area basis. Objective of this study was to evaluate the productivity  of lowland rice at different population densities.  Rice variety IR-64 was planted on 13.2 m x 10 m plot at four population densities (16, 25, 49 and 100 plant m-2)  in a completely randomized design with three replications. Observations were made on the yield components on individual plant basis and grain yield per area. Results indicated that tiller number, number of productive tiller, number of spikelet per panicle, number of fertile spikelet, and grain yield per hill were reduced  as the population density was increased.  On contrary, grain yield per 100 m2 was increased linearly in accordance to the increment of population density, where 47.57 kg grain per 100 m2 produced at the density of 16 plant m-2 and 86.53 kg was produced at the density of 100 plant m-2.

Abstract

[STABILITY IMPROVENT OF STEEP HILL SOIL STRUCTURE BY MEANS OF HYDROSEEDING OF MOSSES AND SOIL CONDITIONERS]. Steep hill is very sensitive to soil erosion and land slide. The objective of this study was to determine the effects of mosses (musci) and soil conditioners applied through hydroseeding technique on the development moss colony and stability of soil structure of steep hill. A randomized complete block design with three replications was used to allocate the treatment combinations of soil conditioners (no soil conditioner, water + manure, and water + manure + latex) and moss species (no moss, Andrea petrophila, and Polytricum commune).  1m x 1m plots were made on steep hill with 65% inclination and each plot was sprayed with 2 L of the soil conditioner and moss mixture (hydroseeding). Observations were made on the moss development and soil physical properties. The results showed that the moss colony increased significantly as applied with soil conditioners.  The highest colony size of moss was found on the application of water + manure + latex (200.85 m-2), followed by water + manure with (156.46 m-2), whereas no soil conditioner produced the lowest (104.91 m-2).  Hydroseeding of moss and soil conditioner had significantly improved the stability of soil structure . Combination of Polytricum commune and water + manure + latex produced the highest improvement in soil structure stability by 93.3 % as compared to the control.

Abstract

[VEGETATIVE AND REPRODUCTIVE PERFORMANCES OF MAIZE HYBRIDS GENERATED FROM INBRED MUTANTS (M4) ON DARMAGA LATOSOL]. The development of hybrids from local germplasms are extensively done as alternative to the expensive imported hybrid seeds. The farthest genetic distance of parental lines is required to develop the best hybrids. The objective of this study was to compare the vegetative and reproductive performances of hybrids generated from crosses of M4 inbred lines, generated from the selected gamma irradiated mutants. Twenty eight hybrids derived from diallel crosses of M4 inbred lines and a check hybrid variety (NK33) were evaluated on Darmaga latosol. The results showed that all hybrids had lower performances on vegetative and reproductive characters compared to NK33. However, based on the selection index involving all characters, hybrids of G3 x G8, G6 x G8, and G8 x G6  with the index values of   9.45, 7.85, and 6.72, respectively,  performed better than or similar to  NK33.
