Abstract

Allelopathy-based bioherbicides for drought-stressed sorghum plants are a concrete step towards sustainable agriculture. The aim was to identify the germination characteristics of sorghum seeds and flavonoid levels in their extracts at various levels of drought stress. Extract materials were prepared from June to August 2024 at Bengkulu University Greenhouse, Kandang Limun Village, Bengkulu City, and bioassay tests were conducted in August 2024 at Pematang Gubernur, Muara Bangkahulu, Bengkulu City. Flavonoid analysis was performed at the Integrated Research and Testing Laboratory (LPPT) of Gadjah Mada University in August 2024. This research used a completely randomized design (CRD) with one factor. One sorghum variety, Super 1, was planted with water stress treatment through watering patterns every day, every 2 days, every 3 days, every 4 days, and every 5 days. The experimental unit was a petri dish, and the experiment was repeated four times. The Petri dish bioassay method was applied in this experiment. Each petri dish was given 10 mL of aqueous extract, and 25 mung bean seeds were planted and incubated for three days. The results showed that the watering pattern achieved the highest flavonoid content every 4 days (4121.00 µg/g), and the second highest flavonoid content was Super 1 + every 5 days. The once every 5 days watering pattern achieved the highest sprout inhibition. The higher the level of stress, the higher the level of inhibition of seed germination, so it has the potential to be the best bioherbicide.

Abstract

Sorghum has the potential to be developed considering that this plant is easy to cultivate in various types of soil and various climatic conditions. The purpose of this study was to determine the dose of bovine bone ameliorant on the growth and yield of sorghum in swampland and to determine the interaction of ameliorant and varieties of sorghum cultivated in swampland. This research is expected to provide information about the effect of giving cow bone ameliorant to several varieties of sorghum in swamps. The research was carried out from February to April 2020, in Gunung Alam Village, Arga Makmur District, Bengkulu Utara Regency. The study used a Completely Randomized Block Design with 12 treatments and 6 replications. The treatment used in this study consisted of two factors, namely the first factor was bovine bone ameliorant with 2 levels, namely bovine bone ameliorant treatment and without beef bone ameliorant treatment. The second factor of sorghum varieties, namely Numbu, Super 1, and Super 2. The results showed that the 50 g dose of beef bone ameliorant gave the highest value in this study.

Abstract

The potential of sorghum plants to produce allelopathy is determined by the variety and the level of stress it receives. This study aimed to obtain information on the potential of sorghum water extract as a bioherbicide due to water stress treatment with different varieties. This study used a one-factor group randomized design. The extract source treatments were as follows: Super 2 + watering once every 1, 2, and 3 days; Suri 4 + watering once every 1, 2, and 3 days; Bioguma + watering once every 1, 2, and 3 days and control. Bioassay method experiments in petri dishes. Each petri dish was given 10 ml of aqueous extract with a concentration of 5%. A total of 25 sorghum seeds were planted and incubated for three days. The results showed that all water extracts from sorghum varieties Super 2, Suri 4, and Bioguma, combined with all water stresses, could inhibit the growth of the test plants. However, Super 2 + once every 5 days inhibited the test plants the most compared to the other treatments. Therefore, these sorghum water extracts have the potential to be used as bioherbicides to control weeds

Abstract

ABSTRACTSoybean extensification on mineral and peaty mineral soils of tidal land are limited by Al and Fe toxicity.  Modification of growing environment and the use of tolerant variety are the possible alternatives to overcome the limitation.  The research was aimed to study soybean productivity in various soil types with different depth of water level and different water compositions. The experiment was held under mineral, peaty mineral soils with interaction types B and C  of tidal swamp in Banyuasin, South Sumatera from May to August 2014.  At each location, there was a three factor experiment was arranged in a split-split plot design. The first factor was two water depth (10 and 20 cm), the second factor was three varieties (Tanggamus, Cikuray, Ceneng) and third factor was three different water compositions (river water, peat water, high-tide water). The results showed productivity on mineral soil types C, peaty  mineral soil types B, and mineral soil types B were 4:50, 3.65, 0:32 ton ha-1 respectively. In peaty mineral soil types B, Ceneng with a depth of 20 cm water level resulted in highest productivity. In the mineral soil overflow type B, Cikuray with peat water composition had highest productivity.Keywords: mineral, peaty mineral, sensitive, tolerant

Abstract

Peningkatan produksi kedelai dapat dilakukan dengan menanam tanaman di lahan marginal, seperti tanah salin. Upaya yang dapat dilakukan untuk mengatasi permasalahan tersebut salah satunya dengan menyeleksi tanaman yang toleran pada kondisi salin. Penelitian dilakukan pada bulan Mei-Juli 2021 di rumah kaca Departemen Agronomi, Fakultas Pertanian, Universitas Bengkulu, 10 m di atas permukaan laut. Penelitian ini bertujuan untuk mengevaluasi toleransi 18 varietas kedelai yang ditanam pada cekaman salinitas. Kedelai ditanam dalam pot plastik berdiameter 10 cm yang dipupuk dengan larutan AB-mix dengan perlakuan 0 dan 6 dSm-1 NaCl selama 15 hari dari cekaman salinitas. Pertumbuhan dan indeks toleran cekaman bibit diukur. Hasil penelitian menunjukkan bahwa varietas kedelai mempengaruhi pertumbuhan tanaman secara berbeda. Selain itu, cekaman salinitas secara nyata mengurangi pertumbuhan tanaman. Hasil penelitian menunjukkan bahwa 18 varietas kedelai tergolong pada toleran salinitas pada tingkat salinitas 6 dSm-1. Kata kunci: salinitas, toleransi varietas kedelai
