Abstract

Procurement of quality seeds and seedlings quickly available for consumers in sugar palm plantations still has many obstacles. Sugar palm seeds take a long time to germinate due to the dormancy period. One effort that can be done is scarification physically and chemically, including using gibberellins. This study aimed to determine the effect of scarification treatment and various concentrations of gibberellin (GA3) on breaking dormancy and germination of sugar palm seeds. This research was carried out in the Seed Technology Laboratory, Faculty of Agriculture, Andalas University, from March to August 2022. The design was used by completely randomized design (CRD) in factorial 3x4x3. The first factor was the scarification technique which consisted of three levels with using sandpaper, hand grinding, and sitting grinding. The second factor was soaking the seeds in GA3 solution with four levels which consisted of 0 ppm, 50 ppm, 100 ppm, and 150 ppm. The results of this reseach showed that the seed scarification technique had effected on the seeds water content and the electrical conductivity of the sugar palm seeds, while seed scarification and gibberellin immersion had effected the dormancy time of the sugar palm seeds, but it didnot effect the germination ability of the sugar palm seeds. Seed scarification used a sitting grinding machine and gibberellins with concentration of 100 ppm would have efficiented the fastest breaking dormancy of sugar palm seeds in 18.67 days.INTISARIPengadaan benih bermutu dan bibit yang cepat tersedia bagi konsumen pada tanaman aren masih memiliki banyak kendala. Benih tanaman aren memerlukan waktu yang cukup lama untuk berkecambah yang disebabkan terjadinya masa dormansi. Salah satu upaya yang dapat dilakukan adalah dengan melakukan skarifikasi secara fisik dan kimia diantaranya dengan penggunaan giberelin. Tujuan penelitian ini adalah untuk mengetahui pengaruh perlakuan skarifikasi dan berbagai konsentrasi giberelin (GA3) terhadap pematahan dormansi dan perkecambahan benih aren. Penelitian ini telah dilaksanakan di Laboratorium Teknologi Benih Fakultas Pertanian Universitas Andalas pada bulan Maret hingga Agustus 2022. Rancangan yang digunakan adalah rancangan acak lengkap (RAL) dalam faktorial 3x4x3. Faktor pertama adalah teknik skarifikasi yang terdiri dari tiga taraf yaitu menggunakan kertas amplas, gerinda tangan dan gerinda duduk dan faktor kedua adalah perendaman benih dalam larutan GA3 dengan empat taraf yaitu: 0 ppm, 50 ppm, 100 ppm dan 150 ppm. Hasil penelitian menunjukkan bahwa teknik skarifikasi benih berpengaruh terhadap kadar air benih dan daya hantar listrik benih aren, sedangkan skarifikasi benih dan perendaman giberelin berpengaruh terhadap waktu patah dormansi benih aren, namun tidak mempengaruhi daya berkecambah benih aren. Skarifikasi benih menggunakan mesin gerinda duduk dan giberelin konsentrasi 100 ppm menghasilkan waktu pematahan dormansi benih aren tercepat yaitu 18,67 hari.

Abstract

Tanaman karet merupakan sumber utama bahan karet alam dan komoditas perkebunan yang mempunyai peran penting di Indonesia. Hampir 20.000 Ha perkebunan karet di Indonesia sudah berumur lebih dari 30 tahun. Proses replanting perkebunan tua dengan menggunakan beberapa klon unggul yang diharapkan dapat meningkatkan produksi karet, disisi lain menimbulkan permasalahan baru yakni tingginya serangan hama dan penyakit. Salah satu hama yang menyerang adalah hama kutu tempurung. Kutu tempurung merupakan hama dari golongan serangga ordo Hemiptera dan famili Coccidae. Kutu tempurung menjadi hama yang lebih berbahaya dengan kehadiran semut. Beberapa spesies semut memiliki hubungan simbiosis dengan kutu tempurung. Untuk mengetahui spesies semut maka dilakukan penelitian keanekaragaman dan morfologi semut yang berasosiasi dengan kutu tempurung pada tanaman karet di pembibitan. Penelitian ini dilaksanakan pada bulan april sampai bulan Juni 2018 di Nagari Sungai Dareh dan Kurnia Selatan. Lokasi pengamatan berupa pembibitan karet dengan klon PB 260 yang berumur 5 bulan. Pada hamparan pembibitan dipilih 3 blok dengan jumlah bibit 300 batang. Pada blok yang sudah ditentukan dipilih tanamn sampel secara langsung. Penentuan tanaman sampel digunakan untuk mengoleksi semut yang berasosiasi dengan kutu tempurung. Berdasarkan pengamatan semut yang terkoleksi sebaanyak 5 subfamili dan 13 spesies. Kelimpahan semut yang paling banyak berasosiasi dengan kutu tempurung yakni D. affinis (1018) dengan indeks keanekaragaman (0.18), indeks kemerataan (0.07) dan indeks nilai penting (0.98). Selain itu diketahui terdapat hubungan antara kelimpahan semut dengan kelimpahan kutu tempurung pada tanaman karet di pembibitan.

Abstract

The community service took place for the Women Farming Group (WFG) of Banda Langik in the Sungai Bangek, Balai Gadang, Koto Tangah District, Padang City, from July to November 2022. It was held in demonstration plots (dump lots) of Liquid Organic fertilizers (LOF) with coconut coir, and banana stems as raw materials. These raw materials were straightforward to find in this area. Plots were made of 2 beds, and each was planted with pull-out Kale from seeds. Each bed was divided into two parts: without LOF and given LOF. It helped the WFG members differentiate the growth and yield pull-out Kale between being given LOF and without LOF. LOF was made by fermenting coconut coir separately and banana stems in a closed bucket for two weeks. The fermented products were sprinkled on the plants every week, starting at the age of two weeks after planting until they were close to harvest. The results showed that the plants given LOF were higher than those without LOF. The plant has given LOF more leaves. Their length and width of leaves were more significant than those without LOF. LOF is very useful given to vegetable plants, especially pull-out Kale.

Abstract

One of the factors hindering the development of upland rice cultivation among annual crops is the limited number of shade-tolerant upland rice varieties. It is very important to assemble shade-tolerant upland rice varieties with high yields. The purpose of the study was to determine the effect of shade on the growth and productivity of five genotypes of upland rice. This research was carried out in the experimental garden of the Faculty of Agriculture, the Islamic University of North Sumatra with an altitude of 25 m above sea level, from June to December 2020. The research design was split-plot and repeated three times. The main plot of shade treatment consisted of two levels, namely no shade (0%) and shade treatment (70%). The sub-plots were five genotypes of upland rice in Deli Serdang and two shade-tolerant varieties. Shade treatment affected the growth and productivity of five genotypes of upland rice in Deli Serdang District (Sialus, Arias, Ramos Merah, Silayur, and Sirabut) and two shade-tolerant varieties (Rindang 1 and 2). Two genotypes of upland rice were obtained, namely Silayur and Sirabut which were more shade tolerant, based on flowering age, harvest age, and grain weight per clump. When compared with Rindang 1 and 2 varieties, the two genotypes of upland rice were the same or more tolerant.

Abstract

Conductivity test is a test to physically measure the electrolyte leaking from seeds and be classified as vigor test. However, some factors may affect the result of the test; therefore, standardized procedures should be defined for its accuracy and consistency. The research reported here was aimed at obtaining specific method of conductivity test for wheat seeds and to study the correlation between conductivity test result with seed germination and field emergence. The experiments were conducted at the laboratory of BBPPMBTPH, Cimanggis, Depok from February to June 2013. The experiment was designed to identify the correct amount of wheat seeds and the volume of water used to soak the seeds. The experiment was assigned according to a completely randomized design (CRD) with 20 wheat seed lots and three replicates. Data collected including seed germination (SG), vigor index (IV) or First Count Test (FCT), field emergence (FE) at 8, 14, and 21 days, tetrazolium test (TZ), and conductivity test for nine combinations of wheat seed amount and the water volume for soaking (50, 75, and 100 seeds in 100, 150, and 200 mL of water). Results show that soaking 75 wheat seeds in 200 mL of water was best for conductivity test. This soaking condition resulted in negatively significant correlation between seed germination and field emergence. Moreover, low value of conductivity resulted in high values of SG, IV, FE, and TZ. Wheat seed germination and field emergence can be estimated using the equations of y = 0.028x2 – 3.321x + 104.9 and y = 0.022x2 – 2.704x + 87.96, respectively.

Abstract

One of the efforts that can be done is to increase the national corn productivity by developing prolific composite corn varieties. This is done because prolific corn is a type of corn with a tendency to produce two or more cobs, so that it can increase the value of corn production. The purpose of this study was to obtain prolific corn candidates (two cobs) with high yield and uniformity. This research was conducted using the mass selection method. Mass selection is done by selecting plants that have the desired character, namely prolific corn (cob two). The observed variables were the diversity in the F4 population, the percentage of prolific maize, and the comparison of the yield components of prolific maize with non-prolific maize. This study succeeded in obtaining 50% prolific corn on the cob and has wide diversity criteria. Of the 561 prolific corn plants, there are 91 corn plants that are classified as productive prolific. Prolific maize has a higher yield component than non-Prolific maize. Seed weight with cobs on productive prolific corn reached 318 g and seed weight reached 268 g.
