<p><strong>Background</strong>. Shallot plant is an important commodity in Central Sulawesi because it functions as a raw material in the fried onion home-industry. <strong>Objective.</strong> The aim of this study was to evaluate the effect of mulch and organic fertilizers on the agronomic performance of the “Lembah Palu” variety of shallot (<em>Allium cepa </em>L. var. <em>Aggregatum</em>) on dryland. <strong>Methodology.</strong> The experiment consisted of three types of mulch (no mulching, rice straw, and <em>Gliricidia sepium</em> leaf) and four types of organic fertilizers (no fertilizer, bioculture, biourin and cattle manure compost). The experiment was laid out as a randomized complete block design in a factorial arrangement with three replications. A total of 36 plots were used for the experiment. The agronomic performance measured were: plant height, number of leaves per plant, number of tillers, fresh weight, dry weight, bulb diameter and bulb yield of shallot. Environmental parameters include temperature and humidity. <strong>Result.</strong> Results showed that the application of rice straw mulch plus bioculture organic fertilizer had positive  significant effect (<em>P≤ 0.05</em>, respectively) on next agronomic parameters: plant height, number of leaves per plant, number of tillers, fresh weight, dry weight, bulb diameter and yield bulb of shallot. <strong>Implications. </strong>Significantly positive results on the agronomic parameters of shallots indicate that the application of mulch and bioculture organic fertilizers can be used on other crops to increasing the efficiency of dryland.<strong> </strong><strong>Conclusion.</strong> The highest production of shallots was 9.46 t^.ha^-1. Thus, it can be recommended that straw mulch at a dose of 5 t^.ha^-1 and bioculture at a dose of 750 L^.ha^-1 is better for the growth and yield of shallot in dryland. The use of rice straw mulch and bioculture as organic liquid fertilizer provides benefits to increase productivity, add value to the crop and livestock waste, reduce environmental pollution, and application to plants will produce healthy products.</p><strong></strong>

Abstract. Pasaru F, Yunus M, Toana MH, Edy N, Anshary A, Saleh S. 2021. Incidence of banana leaf roller and diversity of it is parasitoids in Central Sulawesi, Indonesia. Biodiversitas 22: 5023-5029. Incidence of banana leaf roller and diversity of it is parasitoids in Central Sulawesi, Indonesia. Indonesia is still facing banana losses due to the leaf roller (Erionota thrax). Fortunately, it has several natural enemies potentially to control them. Therefore, a survey was done to measure the incidence of banana leaf roller (BLR) at different altitudes and banana cultivars as well as the diversity and parasitism of its parasitoids. The pra-imago stages of BLR were collected at different altitudes and banana cultivars in Central Sulawesi, Indonesia, and transported to the laboratory for rearing and parasitism observation. The study revealed that the incidence of E. thrax in the surveyed locations varied from 28.6% to 85.8%, whereas the parasitism level of the BLR parasitoids was 0.0 to 22.1%. Incidence of E. thrax tended to be higher at a higher altitude while Kepok cultivar seemed to be less prone to BLR infestation compared with Raja and Mas cultivars. A total of nine parasitoids of BLR were recorded. They were Agiommatus sumatraensis, Pediobius erionotae, Ooencyrtus pallidipes, Brachymeria lasus, Brachymeria thracis, Cotesia erionatae, Xanthopimpla gampsura, Casinaria sp, and Palexorista solennis. Among them, B. lasus was the most abundant, widely distributed, and had the highest parasitism rate. Our study figured out that BLR infestation is a major problem in Central Sulawesi. Nevertheless, the presence of parasitoids recorded in this study may potentially be used as the biological control.

Moutong merupakan salah satu kelompok tani yang aktif dalam budidaya padi sawah. Masalah yang dihadapi dalam budidaya padi adalah: (1) kurang tersedianya pupuk organik, (2) rendahnya produktivitas padi yang dihasilkan, (3) serangan hama dan penyakit, dan (4) manajemen organisasi kelompok masih lemah. Program Kemitraan Masyarakat bertujuan untuk membantu petani menerapkan teknik menanam padi sawah organik, mengembangkan input dan bahan produksi untuk mengendalikan hama dan penyakit secara ekologis, dan menyediakan makanan sehat bagi masyarakat. Metode pelaksanaannya meliputi: pembinaan dan pelatihan, praktek teknis dan demonstrasi, pertanaman percontohan serta pembinaan partisipatif. Hasil pelaksanaan kegiatan pengabdian menunjukkan bahwa pengetahuan dan keterampilan peserta meningkat. Pada pelaksanaan demplot budidaya padi sawah organik terlebih dahulu diaplikasikan pupuk organik yang telah dikembangkan sebelumnya ke lahan yang akan ditanami sebagai pupuk dasar, kemudian dilakukan penanaman bibit padi yang sesuai dengan prinsip good agriculture practise. Pelaksanaan demplot tersebut adalah dalam rangka mendukung program pemerintah daerah yaitu Kabupaten Parigi Moutong sebagai daerah beras di Sulawesi Tengah.
