Abstract

Canopy Arthropod Community Dwellers in Maize Planting. Dwellers the canopy arthropod community structure observed in maize planting in the Village Bajeng, District of North Polombangkeng, Takalar District, South Sulawesi. Observation of the canopy arthropod dwellers performed using suction machine. The results showed that the arthropod community on corn cropping consists of arthropod natural enemies, fitofag and other arthropods. Most of the arthropods that act as predators, which consists of four insect family is Formicidae, Coccinellidae, Carabidae, Gryllidae, and the two spider families is Lycosidae and Linyphiidae. Maize crop canopy arthropod dwellers generally is formicid, coccinellid, cicadellid, and pentatomid. In the maize crop canopy, formicid and aphid abundance were higher in the edge plots, whereas coccinellid, lycosid, and linyphiid higher in the center of the plot.

Abstract

Erosion Hazard on Production Forest Area at Gerokgak, Buleleng, Bali The experiment about erosion hazard has been conducted at production forest area at Gerokgak, Buleleng, Bali. The aims of the research are to predict erosion and determine the erosion hazard. The method used in this research is USLE (Universal Soil Loss Equation). Land unit was classified base on slope, land use pattern, and soil type. The result of the research showed that soil erosion was classified as moderate to heavy. The moderate erosion was occurred at land unit 18 (58.104 tons/ha/year); heavy erosion at land unit 19 (65.059 tons/ha/year); 20 (31.342 tons/ha/year); and 24 (52.895 tons/ ha/year); and very heavy erosion at land unit 16 (934.799 tons/ha/year); 17 (668.072 tons/ha/year); 21 (266.799 tons/ha/year); 22 (285.735 tons/ha/year); 23 (65.652 tons/ha/year), 24 (260.962 tons/ ha/year); 25 (295.207 tons/ha/year); 26 (249.304 tons/ha/year and 271.329 tons/ha/year); and 27 (130.757 tons/ha/year).

Abstract

Assessment of Various Fertilizer Recommendation on Growth, Yield Components, and Yield of Inpari 1 Rice Variety. Integrated fertilizer application to new high yielding variety (HYV) and irrigation technology give largest contribution to rice production with supports of good practices and pest and disease control (IPM). Therefore, an assessment on wetland rice production with four fertilizer recommendation such as : package, ICM, NPK+LCC and PuPS (Site Specific Fertilizing on Rice). It was used Randomized Block Design with four replications were conducted in Tanjung Sari village, Pondok Salam subdistrict, Purwakarta district, in dry season 2009. The objectives were to obtain the best fertilizer recommendation on growth, yield components, and yield of Inpari 1 rice variety. The results showed that fertilizer recommendation of NPK+LCC significantly affected plant height, number of tiller, and number panicles per hill of Inpari 1 variety, while number of total grains per panicle, filled grain number per panicle, 1000 grain weight, and dry grain yield were not affected by fertilizer recommendation (Package, ICM, NPK+LCC, and PuPS). Fertilizer recommendation of NPK+LCC increased yield of 0.84 t/ha compared that to package recommendation.
