Abstract

Tanaman padi memerlukan unsur fosfor (P) dalam proses pertumbuhan dan perkembangannya. Pentingnya peran fosfor dalam mendukung peningkatan produksi pada tanaman padi menyebabkan unsur ini harus selalu tersedia pada saat penanaman padi, sehingga pemupukan di lahan sawah seringkali dilakukan secara intensif. Namun demikian kebanyakan lahan Indonesia telah jenuh fosfat, tetapi P tersebut tidak dapat dimanfaatkan semaksimal mungkin oleh tanaman karena P dalam bentuk terikat. Salah satu alternatif untuk meningkatkan efisiensi pemupukan fosfat dalam mengatasi rendahnya fosfat tersedia dalam tanah adalah dengan memanfaatkan mikroorganisme pelarut fosfat yaitu dengan penggunaan bakteri Bacillus amyloliquefaciens yang dapat melarutkan fosfat tidak tersedia menjadi tersedia sehingga dapat diserap tanaman. Penelitian bertujuan untuk mengetahui dosis bakteri B. amyloliquefaciens terbaik untuk mengurangi penggunaan pupuk anorganik serta meningkatkan pertumbuhan dan hasil tanaman padi metode SRI. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan dua faktor. Faktor pertama adalah dosis pupuk fosfor terdiri atas 4 (empat) taraf perlakuan yaitu 25, 50, 75, dan 100%. Faktor kedua adalah dosis bakteri B. amyloliquefaciens terdiri atas 3 (tiga) taraf perlakuan yaitu 0, 200, dan 400 g/ha. Berdasarkan hasil penelitian disimpulkan bahwa Pemberian bakteri B. amyloliquefaciens 200 g/ha mampu meningkatkan hasil padi metode SRI sebesar 14.9 % menjadi 6.64 ton/ha. Serta Pemberian pupuk fosfor 50% rekomendasi sudah cukup untuk mendapatkan pertumbuhan dan hasil tanaman padi metode SRI yang terbaik.

Abstract

Dwipa I, Syarif A, Suliansyah I, Swasti E. 2018. West Sumatra Brown Rice resistance to Brown Planthopper and Blast Disease. Biodiversitas 19: 893-898. Brown rice is a highly nutritious rice widely consumed as the carbohydrate substitute of common rice. Brown rice resistance to biotic stress is one of indicators of a superior variety. Our study aimed to analyze the response of several brown rice genotypes from West Sumatra to brown planthopper attack and blast disease. This study comprised two experiments, the resistance assay to brown planthopper (Nilaparvata lugens (Stal.) and the resistance assay to blast fungi Pyricularia oryzae. The resistance assay to brown planthopper was done using randomized block design experiment with three replicates. Eighteen brown rice genotypes (15 brown rice, 2 black rice, and 1 control genotype) were tested in the assay. From 17 brown and black rice tested, 7 genotypes were resistant and 2 were moderately resistant. For blast resistance analysis, fifteen rice genotypes (13 brown rice and 2 black rice) were used. There was only 1 genotype highly resistant and 3 moderately resistant to blast disease among those 15 brown and black rice.

Abstract. Marwan AP, Munandar A, Anwar A, Syarif A, Hayati PKD. 2022. Variability, heritability, and performance of 28 West Sumatran upland rice cultivars, Indonesia. Biodiversitas 23: 1058-1064. The abundance of genetic diversity, especially local upland rice cultivars, makes an excellent opportunity to obtain local cultivars with the desirable character. The study aimed to assess the genetic variability and heritability of agronomic traits among local upland rice cultivars from West Sumatra. In this study, 28 local upland cultivars from West Sumatra were subjected to the analysis of variance. The research was conducted from November 2020 to April 2021 at the Research Station of the Faculty of Agriculture, Andalas University, Padang. The evaluation was conducted using a Randomized Complete Block Design with three replicates. Results showed variation in each agronomic trait, ranging from intermediate to tall in plant height, short to moderate in panicle length, low to moderate in the number of tillers, days to flowering and days to maturity, and light to moderate in grain yield. Plant height, number of tillers, days to flowering, and days to maturity were traits with high to moderately high GCV values and high heritability values. The number of tillers and days to maturity could be chosen as selection criteria for assembling superior varieties. Both traits performed high heritability estimates and significant genotypic correlation with grain yield.

Abstract

The use of ex-limestone mining land as an alternative planting medium requires technological innovation to overcome nutrient limitations and unfavorable soil conditions. This study aims to determine the effect of Arbuscular Mycorrhizal Fungi (AMF) types and Yomari liquid organic fertilizer (POC) concentrations on the growth of oil palm (Elaeis guineensis Jacq.) seedlings at the pre-nursery stage in limestone mining waste soil. This experimental research was conducted in February - May 2025. The experiment was conducted at the Experimental Garden UPT, Faculty of Agriculture, and Plant Physiology Laboratory, Faculty of Agriculture, Andalas University, Padang. The design used was a factorial Completely Randomized Design (CRD) with two factors, namely the type of AMF (Glomus sp., Gigaspora sp., and a combination of Glomus sp. x Gigaspora sp.) and the concentration of Yomari POC (0; 0.5; 1.0; and 1.5 mL L⁻¹) which were each repeated three times, resulting in 36 experimental units. Each experimental unit consisted of 9 plants, with 5 samples for destructive observation and 4 samples for non-destructive observation, resulting in a total of 324 sample plants. The results showed no significant interaction between AMF types and POC concentrations on all growth parameters. However, individually, the AMF Glomus sp. type proved to be the most effective in supporting the growth of oil palm seedlings, as indicated by a high percentage of root colonization, increased phosphorus (P) uptake, and an increase in root length and volume. Meanwhile, the application of POC Yomari at a concentration of 1.0 mL L⁻¹ resulted in the best seedling growth, indicated by an increase in P uptake parameters, root length, and root volume. This indicates that the application of Glomus sp. AMF and POC Yomari at a dose of 1.0 mL L⁻¹ is effective in supporting the growth of oil palm seedlings in post-limestone mine soil media. In addition, the results of this study provide a scientific basis for the use of arbuscular mycorrhizal fungi and liquid organic fertilizer as a sustainable soil management strategy for post-mining land rehabilitation and improvement of oil palm nursery practices.

Abstract

This study aimed to determine the interaction between the best AMF types and doses, the best AMF types, and the best doses on the growth of cocoa seedlings planted in after-lime mine soil. The experimental study was conducted from February to June 2025. This research was conducted at the Wire House, Faculty of Agriculture, Andalas University, Padang City, West Sumatra, in the Seed Science and Technology Laboratory, Faculty of Agriculture, Andalas University. Root colonization observations were conducted at the Plant Physiology Laboratory, Faculty of Agriculture, Andalas University, Padang. The study used a factorial completely randomized design (CRD) consisting of two factors. The first factor was the type of AMF, with three levels: Glomus sp., Gigaspora sp., and Acaulospora sp. The second factor was the AMF dosage, with four levels: 0 g/seedling, 10 g/seedling, 20 g/seedling, and 30 g/seedling. Data were analyzed statistically using the F-test at a 5% significance level. If the calculated F-test was greater than the table F-test, the analysis was continued with Duncan's New Multiple Range Test (DNMRT) at a 5% significance level. The results of this study indicate that there was no interaction between the type and dosage of AMF on the growth of cocoa seedlings planted in ex-lime mining soil. The Glomus sp. AMF was the best AMF for enhancing the growth of cocoa seedlings planted in ex-lime mining soil. Meanwhile, the AMF dosage of 30 g/seedling was the best for enhancing the growth of cocoa seedlings planted in ex-lime mining soil.
