Abstract

A study aiming at comparing the effectiveness of seed extract of Phaleria papuena Warb andchemical insecticides for controlling beet armyworm pest (Spodoptera exigua Hubner) at the onioncrops has been conducted. The experiment was set up by using a completely randomized design(CRD) with five treatments and tree replicates. The treatments applied were: without insecticideapplication as a control (P0), botanical insecticide, Phaleria papuena extract 2% (P1), 4% (P2), and6% (P3), and chemical insecticide, prevathon 50 SC (P4). Variables measured were Spodoptera exiguapopulation density and intensity of pest infestation. Results showed that application of botanicaland chemical insecticides significantly reducing the population density and the infestation ofSpodoptera exigua. Effectiveness of Phaleria papuena extract 6% (P3) and prevathon (P4) was notsignificantly different in controlling Spodoptera exigua. In average, the application of Phaleria. papuenaextract 6% (P3) and prevathon (P4) reduced population density at 9.4% and 9.3%, respectively, andinfestation intensity of Spodoptera exigua 37.8% and 36.7%, respectively. These results suggestthat the seed extract of Phaleria papuena is highly potential to be developed as botanical insecticide.Key Words: Botanical insecticides, Phaleria papuena, Spodoptera exigua.

Abstract

Assessment of six varieties of in-hybrid swamp rice (Inpara) adaptation at Debowae village, district Waeapo, Buru regency was conducted from September to December 2011. The assessment goal was to get 1 to 2 adaptive varieties with high productivity on sub-optimal land. The land area size used was 1 hectare. The assessment were done for six varieties namely Inpara 1 (V-1), Inpara 2 (V-2), Inpara 3 (V-3), Inpara 4 (V-4), Inpara 5 (V-5) and Indragiri (V-6). This research used a Randomized Block design replicated 3 times (farmers as replicates). Fertilizers used were 300 kg NPK Phonska ha-1, 200 kg urea ha-1 and 3 t of manure ha-1. Rice cultivating was done based on a model of integrated crop management (ICM). The whole amount of NPK Phonska fertilizer was applied 7 days after planting while urea fertilizer was given twice, half at 7 days after planting (dap), and the rest at 21 and 35 dap. Manure was spread on the plot before planting. Parameters measured were physical and chemical properties of soil, crop growth and yield components. The study results showed that the type of soil at the study site was Endoaquepts with low soil fertility status. The six Inpara varieties are average provide higher productivity(4.87 to 7.95 t ha-1) compared with the average productivity advance (1-2 t ha-1) or grain yield obtained by farmers who plant varieties superior to the rice field (2.60 to 2.90 t ha-1). From the sixth varieties studied, four varieties of which provide results on the 7 t ha-1, which is Inpara 4 (7.95 t ha-1), Indragiri (7.75 t ha-1), Inpara 1 (7.44 t ha-1), and Inpara 2 (7.10 t ha-1), so the opportunity to developmenton the land sub-optimal in the Moluccas, especially in the Buru plains Waeapo.

Abstract

The infertile of Entisol, especially low availability of N, P, and K, causes the decreasing in growth and development of plant. Hence, important efforts on management of Entisol are the increasing in N, P, and K availability for crop demand. The extract of market organic residue compost is as source of organic matter used to improve the soil, although the fertilizers are still not yet have full attention. A study that was aimed to elucidate roles of the market organic residue compost extract on increasing N, P and K availability, improving crop growth and N, P, and K uptake by red onion Palu local variety in an Entisol was conducted in a glasshouse. Twelve treatments consisting of the fermentation duration and concentration of the extract, three rates of fermentation duration (4, 8 and 12 days), four rates of concentration of the extract (0, 5, 10, and 15 cc/L water) were arranged in a factorial randomized block design with three replicates. Results of the experiment showed that application of the extract concentration and fermentation duration significantly increased N, P, and K availability, improved plant growth and increased N, P and K taken up by the plant grown for 45 days.

Abstract

The objective of this research was to study the effect of phosphorus (P) and calcium (Ca) fertilizers on productivity and nutrient uptake of two soybean genotypes under saturated soil culture. The experimental design was a Split Split plot with three factors i.e. P fertilizer, Ca fertilizer and genotype planted under saturated soil culture. Saturated soil culture with P fertilizer (72 kg P2O5 ha-1) and lime (1 ton ha-1) increased the number of pods and grain weight plot-1. Tanggamus variety had higher number of pods and grain weight per plot than Anjasmoro variety. Interaction of phosphorus fertilizer 72 kg P2O5 ha-1 with lime 1 ton ha-1 increased grain weight plot-1. Largest direct effect on increasing grain weight is plant height and the number of branches. The application of P fertilizer (72 kg P2O5 ha-1) and liming (1 ton ha-1) also gave highest uptake of P and Ca. Saturated soil culture technology can be applied to increase soybean nutrient uptake and productivity.

Abstract

Spodoptera exigua and Lyriomisa chinensis are one of the decstuctive insect and main obstacles in development of onion in Donggala. Pest control by chemicals has been widely reported to give a variety of negative impacts. Other efforts are needed as alternative technology to reduce impact of using synthetic chemical insecticides. One of them is entomopathogenic fungi as bio-insecticide. The objective of this research was to collect Beauveria spp. as enthomopathogen fungy. More specifically, number of Beauveria spp. was collected from several location and host as bio-insecticide formulation matter. There were 12 isolates of Beauveria spp. obtained from various locations in Central Sulawesi. Seven isolates from Lepidoptera while the remaining isolates were two from Homoptera, two from Hemiptera, and one from Coleoptera. Various insect species belong to Lepidoptera order investigated were Spodoptera exigua, Helicoperva armigera, Scirphopaga innotata, Ostrinia furnacalis and Plutella xylostella; belong to Homoptera order were Nilaparvata lugens, and Aphids; belong to Hemiptera order were Leptocoryza acuta; and belong to Coleoptera order was Oryctes rhinoceros. The observation indicated that the color of colony was ranged from yellowish white to white. There was no germination difference among the Beauveria spp. isolates in relationto to their location, host of insects, and insect orders. Differences in virulence showed only in Beauveria isolates from Spodoptera exigua with a high virulence against Spodoptera exigua pest and not for the other insects.
