Abstract

ABSTRACT   This study used a randomized block design with five standard treatments as follows: A1 (15 days), A2 (20 days), A3 (25 days), A4 (30 days), A5 (35 days). The treatment was repeated three times. The purpose of this study was to obtain the best age of the seeds in order to obtain high growth and production. The results of statistical analysis showed that there was no siginifcant difference in the number of unproductive tillers 70 days after transplanting, but this was not the case for the leaf area index; 70 days after germination there was a significant difference. A1 treatment (15 days) had the highest LAI is 4, 56. The same result was shown in the weight of 1000 grains of rice where there was a significant difference among treatments; A1 treatment (15 days) weighted 31.12. It was concluded that the age of seedlings after transplanting had a significant effect on LAI and 1000 grain weight of rice grain after harvest. Keywords: Rice, seedling, transplanting ABSTRACT   Penelitian ini menggunakan rancangan acak kelompok dengan lima taraf perlakuan sebagai berikut : A1 (15 hari), A2 (20 hari), A3 (25 hari), A4 (30 hari), A5 (35 hari). Perlakuan diulang sebanyak tiga kali. Tujuan penelitian ini untuk mendapatkan umur bibit yang tepat sehingga diperoleh pertumbuhan yang tinggi. Hasil analisis statistika menunjukkan bahwa tidak terdapat perbedaan yang nyata pada jumlah anakan yang tidak produktif 70 hari setelah pindah tanam namun pada indeks luas daun 70 hari setelah berkecambah terdapat suatu perbedaan yang nyata, terlihat pada perlakuan A1 (15 hari) memiliki ILD tertinggi yaitu 4,56. Hal yang sama terlihat pada bobot gabah 1000 butir terdapat suatu perbedaan yang nyata antara perlakuan yaitu pada perlakuan A1 (15 hari) memiliki bobot tinggi yaitu 31,12. Disimpulkan bahwa umur bibit setelah pindah tanam sangat berpengaruh pada ILD dan bobot gabah 1000 butir padi setelah panen. Kata kunci: Padi, bibit, pindah tanam

Abstract

ABSTRACT   Insect vectors disease is a major problem for chilli crop production in North Sulawesi. The effect is significant in decreasing crop production. The use of plant-derived insecticide is potential and environmentally friendly way in controlling the insect, as a form of integrated pest management. Seeds of Bitung (Barringtonia asiatica) and seeds of soursop (Annona muricata) plants can be used as an organic insectiside to control the several types of insect vectors  in pepper crop. The purpose of this study was to determine effects of the application of extracts of B. asiatica and A. muricata on the growth of insect vector (Aphis gossypii) in pepper and and determine the extracts’s lethal level.  This research was conducted in the Green House of Plant Pests and Diseases Department of the Faculty of Agriculture Unsrat Manado, for 6 months time. The research used a complete randomized design consisting of 6 treatments;  each treatment was consisted of three replications. The results showed that the percentage of dead insects assay (Aphis gossypii) increased as the concentration of the extract used increased. This study found that the concentration of soursop seed extract at 50 g / l and a concentration of 1.75% Bitung seed extract was the best to be used as a botanical insecticide in controlling the insect population vector (Aphis gossypii) in laboratory conditions. It has an effective lethal concentration for 93, 67% and 90.0% of all test insect population. Overall bioactivity increased the effectiveness of soursop Bitung seed extract as botanical insecticides. Keywords: Barringtonia asiatica, Annona muricata, Aphis gossypii, chilli plants ABSTRAK   Serangga vektor penyakit merupakan masalah utama bagi produksi tanaman cabai di Sulawesi Utara karena dapat menurunkan produksi. Salah satu sarana pengendalian yang memiliki peluang baik untuk dikembangkan dalam menunjang penerapan PHT adalah pemanfaatan bahan insektisida yang berasal tumbuhan.
