Abstract

Red onion (Allium azscalonicum L.) is a kind of Horticultural commodity that has big opportunity in the sector of Agribusiness. This research aimed to determine of the diversity and evenness of Arthropod that are distributed under different planting patterns. This research started on April until July 2016, located in Sidera, Sigi Biromaru Sub district, Sigi Biromaru Regency, Central Sulawesi. The method used in this research was an absolute method (a unit sample used was an area size of 1m x 4m within which observations to all individual Arthropod were done systematically) and the nisbi method (Pitfall, Sweep, and Yellowtraps were used). The planting pattern simple mented in this research were red onion – red onion, red onion – chili, and red in the planting pattern of red onion – beans. The diversity of Arthropod on the different planting patterns and the planting pattern of red onion – chili and red onion – beans was classified as medium category with the production of red onion was 3.49 ton/ha. Keywords : Arthropoda, Diversity, Onion, Planting Patterns.

Abstract

Red onion (Allium ascolanicum L.) is one of the leading vegetable commodities that farmers have long been cultivated intensively.The low productivity of onion due to cultivation techniques conducted at the field level is not adequate, and the use of NPK inorganic fertilizers is still diverse. One alternative that can be done to improve the growth and yield of onion is the choose of the right type of NPK fertilizer. This study aims to obtain a proper dose of NPK fertilizer on the growth and yield of onion crops. This research was conducted in Sidera village, Biromaru sub district, Sigi regency, Central Sulawesi province, This research used Randomized Block Design (RAK) consisting of 5 treatment levels: P0 = control, P1 = 75 kg.ha-1 of NPK fertilizer, P2 = 150 kg.ha-1 NPK fertilizer, of P3 = 225 kg.ha- 1 of NPK fertilizer, and P4 = 300 kg.ha-1 of NPK fertilizer. All treatments were repeated 4 (four) times, so overall there were 20 experimental units.The results showed that the dosage of NPK fertilizer of 300 kg.ha-1 had a significant effect (the best) on the growth and the yield of onion crop that indicated by the average plant height of 33.10 cm, average number of leaves of 22,50 strands, total dry weight of 6.02 g, total tuber per hill of 6.13 fruit, tuber weight per hill of 25.48 g, and tuber yield per hectare of 12,06 ton.ha-1 . Keywords: Onion, NPK Fertilizer.

Abstract

This study aimed to know the effect of light trap intensity on the population density and intensity of S. Innotata attack. This research was conducted using the method of observation, with two light trap type of LED with a power of 5 watts and 10 watts, each light trap placed between two observed plots. Observation plots were observed in this study were four plots with the size of 30x20,5m. In each sectional observation was made by 5 measuring of 2x2m observation point, so that the total number of observed in plots this study were 20 subplots. Planting on each plot using “Jajar Legowo” system with the size of 20x40m. Population and intensity of S. innotata were analyzed using t-test. The results of this study showed that the number of adult S. innotata at 5 watt lamp light treatments da 10 watt increased starting from the first week of observation until the final week of observation, where the observation is done once a week for 8 times observation. Total catches imago of S. innotata at most in 5 watt is 110 tails and in 10 watts the highest number of catches is 219 and the result of t-test analysis is that the treatment between the fluorescent lights of 5 watts and 10 watts significantly effect on the intensity of S. innotata observed. Keywords: Intensity of the attack, Lamps traps, and S.innotata, population.
