An experiment was conducted in July-November 2013 to study the effect of transparent plastic tunnel and mulch on the growth and production of Lembah Palu shallot variety. The experiment was arranged in Split Plot Design and the combination treatments were replicated thrice. The main plot was transparent plastic tunnel consisted of without transparent plastic tunnel and transparent plastic tunnel of 0.13 mm thick. The sub plot was kinds of mulch included without mulch, paddy straw and black plastic. The Anova was used to determine the effect of treatments, and the honestly significant different at α of 0.05 to examine the differences among the treatments. The use of transparent plastic tunnel combined with paddy straw mulch increased the diameter of leaf sheet. Single treatment of transparent plastic tunnel produced higher plant height, total leaf number, total tuber clump-1 and fresh tuber weight ha-1 than without the transparent plastic tunnel. The application of paddy straw mulch and black plastic mulch resulted in higher number and length of leaf sheet, and weight of fresh tuber clumb-1 of Lembah Palu shallot variety compared to that without the mulch. Key words : Growth and production, mulch, shallot, and transparent plastic tunnel.

Community needs for the shallot commodity take place regularly every day because it is a food flavoring ingredient. For this reason, it needs to be followed by the availability of production supplies that are in accordance with consumer needs. Sigi Regency is one of the centers of shallot and chili production in Central Sulawesi, so far it has not been able to make a real contribution in meeting the needs of the community which tends to increase. This is because the exploitation of shallots and chillies is still monoculture, so the risk of crop failure, production decline and farmers' losses is very high. This research was carried out with the aim to determine the growth and yield of shallots planted with various cropping patterns mong chillies, so that information on suitable cropping patterns can be obtained to ensure the availability of high yields of shallots and chillies to meet community needs. The results showed that (i) various shallot cropping patterns among chilli plants did not significantly affect the greenness of leaves, tuber length, fresh weight per tuber, fresh weight of tuber per clump, harvest index and moisture content of shallot bulbs; (ii) leaf length, harvest age and fresh tuber weight of onion bulbs per hectare planted with different cropping patterns among chilli plants were not significantly different, except with monoculture shallot cropping patterns obtained by longer leaves, shorter harvest age (62.0 days) and the weight of fresh bulbs per hectare is higher (1.83 t / ha) compared to various shallot cropping patterns among chilli plants.

This study aimed to determine the influence of atonic concentrations which can increase plant growth and yield of shallot (Allium cepa L. Aggregatum Group) of Lembah Palu variety. This study was conducted from February to May 2015in Bulupountu village, Sigi District, Central Sulawesi Province. This study used a Randomized Block designin which grouping was based on diameter of shallot bulbs. Five treatments with four replicates were applied including Control (A0), 0.25 ml atonic/l water(A1),0.50 ml atonic/l water (A2), 0.75 ml atonic/l water(A3), and 1.0 ml atonic/l water (A4).Datawas analyzed using analysis of variance (ANOVA) followed by a HSD test at 5% if the atonic effect was significant. The atonic concentrations significantly affected the growth and yield of Lembah Palu shallot variety in which the best treatment was found in the application of 1.0 ml atonic/l water. Keywords: Atonic, Lembah Palu shallot variety.

Shallot 'lembah palu' variety is the main raw material for fried onion industry in Central Sulawesi. This study aims to examine the LEISA technology package through the use of liquid and solid organic fertilizers from agricultural waste in order to obtain the quality of shallot bulbs that are good as raw material for fried onions. Research using Randomized Complete Block Design (RCBD) was repeated 4 (four) times. Treatment consists of: (A)= without organic fertilizer; (B)= liquid organic fertilizer (Biourin 40 mL/L of water); (C)= solid organic fertilizer (bokashi goat manure 20 ton/ha); (D)= solid organic fertilizer (bokashi goat manure 10 ton/ha) + liquid organic fertilizer (Biourin 20 mL/L of water); (E) = solid organic fertilizer (bokashi goat manure 20 ton/ha) + liquid organic fertilizer (Biourin 40 mL/L of water); (F)= solid organic fertilizer (20 ton/ha bokashi mixture of goat manure and shallot residues); (G)= solid organic fertilizer 20 ton/ha bokashi mixture of goat manure and shallot residues)+liquid organic fertilizer (Biourin 30 mL/L of water); (H)= solid organic 10 ton/ha bokashi mixture of goat manure and shallot residues)+liquid organic fertilizer (Biourin 60 mL/L of water; and (I)= solid organic fertilizer 30 ton/ha bokashi mixture of goat manure and shallot residues)+ liquid organic fertilizer (Biourin 60 mL/L of water). The results of the study were (i) the combination of types and doses of organic fertilizer in general resulted in higher growth and yield of shallots compared to without organic fertilizers, and (ii) a combination of solid organic fertilizer (mixture 20 ton/ha bokashi goat manure and shallot residue), produce number of leaves, leaf dry weight, fresh weight per tuber, and fresh weight of tuber per hectare higher than without organic fertilizer.

The need for raw materials of fried onions derived from 'lembah palu Shallot tubers variety is high enough and can not be fulfilled, because the productivity is still low. This study aimed to find the type of plant growth regulator substances (PGR) with a long period of proper immersion to improve the germination of Shallot tuber. The research was conducted on Mei until June 2017 in Bulupontou Village, Sigi Regency. The study used two factorial Randomized Block Design (RBD). First factor of type RGS: (Z1) onion extract 100 g/l water, and (Z2) atonic 5 ml/l water. The second factor was long seed immersion in PGR: (T1)=30 min; (T2)=60 minutes; (T3)=90 minutes, and (T4)=120 minutes. Each treatment was represented 20 plants and repeated 3 times, so it was used 480 plants. The results showed that (i) red onion tubers soaked with Shallot extract 100 g/liter of water for 30-90 minutes yielded 100% Germinations, and tubers soaked in red onion extract for 30 minutes resulted in germination rate 31.3%/etmal, (ii) the type of growth regulator of shallot extract and atonic (PGR) effect was not significant on the germination of shallot; and (iii) the 30 minute long growth regulator immersion produced the highest hypothetical vigor index.

Gulma yang tumbuh ke permukaan tanah berasal dari simpanan biji gulma di dalam tanah. Terdapat banyak propagul gulma yang tersimpan di dalam tanah sawah. Penelitian ini bertujuan untuk mengidentifikasi propagul gulma pada berbagai jenis tanah sawah. Penelitian dilakukan sejak Februari hingga Mei 2019 di rumah kaca Fakultas Pertanian Universitas PGRI Yogyakarta. Percobaan disusun dalam rancangan acak lengkap (RAL) faktorial dan diulang tiga kali. Faktor pertama adalah jenis tanah sawah terdiri atas empat macam, yaitu: tanah pasir pantai, vulkanik, latosol, dan regosol. Faktor kedua adalah kedalaman tanah terdiri atas enam aras, yaitu: 0-5, >5-10, >10-15, > 15-20, >20-25, dan >25-30 cm. Hasil penelitian menunjukkan bahwa jumlah jenis gulma tertinggi pada tanah regosol, kemudian menurun pada tanah pasir pantai dan terendah pada tanah vulkanik dan latosol. Jumlah propagul gulma tertinggi terdapat pada tanah regosol di kedalaman >10-15 cm. Temuan penelitian menunjukkan bahwa ada perbedaan nyata jumlah propagul gulma antar jenis tanah maupun antar kedalaman tanah sawah. Kami menyarankan bahwa untuk pengendalian gulma agar berhasil maksimal, maka perlu disesuaikan dengan jenis tanah sawah untuk budidaya padi.
