Abstract

The beet armyworm, Spodoptera exigua is a notorious pest that inflicts significant damage to shallot crops, especially leeks, causing leaves to wither due to brown spots and transparency. This issue often leads to excessive chemical control measures, which, in turn, promote insecticide resistance. This study hypothesized that symbiotic bacteria within S.exigua have the capacity to degrade chlorpyrifos-based insecticides. S.exigua samples were collected in Dringu, Gending, and Leces districts, Probolinggo, and subsequently examined for symbiotic bacteria with biodegradation potential. Bacterial exploration and identification were conducted from April to October 2023 at the Pesticide Toxicology Laboratory, Brawijaya University. The study analyzed the clear zone diameter produced by bacteria in media contaminated with chlorpyrifos-based insecticides as an indicator of biodegradation. Out of 41 surviving bacterial isolates, 10 demonstrated notable biodegradation capabilities. The Genus identification revealed that Erwinia sp., Pantoea sp., and Coryneform sp. were among the contributing bacteria. This research emphasizes the potential role of S.exigua-associated symbiotic bacteria in managing chlorpyrifos-resistant pest populations, offering a promising avenue for sustainable pest control methods.

Abstract

Bambara groundnut (Vigna subterranea L.) is a legume plant from Africa. This plant is a promising food crop because it has many benefits regarding nutritional content, health, and agronomic aspects. However, efforts to increase the genetic diversity of potential yields are constrained by the limited genetic resources with high yields. Polyploidy induction increases plant diversity by giving chemical mutagens such as colchicine. This study aims to obtain the optimal concentration for the induction of bambara groundnut plant diversity with the drip method. This research was carried out from May 2022 to July 2022, located in the experimental field and at the Plant Breeding Laboratory, Faculty of Agriculture, Brawijaya University. The treatments used were different concentrations of colchicine, namely K0: 0% (control), K1: 0.1%, K2: 0.2%, K3: 0.3%, K4: 0.4%. The analysis of variance with the 5% level test showed that the colchicine concentration treatment significantly affected all observations of the bambara groundnut plant's quantitative character. The coefficient of the diversity of plants treated with colchicine was higher than the control treatment. The concentration used in this study did not cause the death of 50% of plants, so the LC50 value has not been found. Abnormal plants were found at 0.3% and 0.4% colchicine concentrations with different leaf shapes from the control plants.

Abstract

Sunflower (Helianthus annuus L.) it has high economic potential as a raw material for the food industry and is extracted to produce vegetable oil. The high use of sunflowers causes this plant to be widely cultivated around the world, including in Indonesia. Sunflower production in Indonesia is not enough to meet market needs due to low knowledge related to seed quality. Quality seeds of appropriate size can affect germination and plant growth character. The purpose of this study is to determine the relationship between physical quality and physical character of seeds on the germination of sunflower seeds. The research activity was carried out at the Plant Breeding Laboratory, Faculty of Agriculture, University of Brawijaya Malang in the month of Mare-June 2024. The research was conducted using observation and measurement methods. The variables observed were seed length, seed width, seed thickness, weight of 1000 seeds, seed moisture content, germination power, maximum growth potential, vigor index, growth speed, growth synchronicity, plumula and radicle length. This study uses the analysis of diversity coefficient and correlation coefficient. The results showed that the physical character of sunflower seeds between genotypes had medium diversity and within genotypes had low to high diversity. Physical quality characteristics and physical characteristics of seeds between size groups regardless of genotype, between genotypes, and in genotypes have a positive correlation for all germination characteristics. The improvement in physical quality and seed size was followed by an increase in germination characteristics. Large seeds have a larger embryo size and food reserves as well as enough nutrients to support embryonic development during the germination phase.

Abstract

Kelapa sawit memiliki potensi yang besar dalam meningkatkan sumber devisa negara. Salah satu upaya yang dapat dilakukan adalah meningkatkan mutu bibit kelapa sawit pada tahap pre-nursery dengan penggunaan komposisi media tanam dan interval pemberian air yang sesuai agar kelapa sawit dapat tumbuh dengan maksimal. Media tanam yang digunakan adalah tanah (top soil) dan pupuk kandang. Tujuan penelitian ini untuk mempelajari pengaruh antara media tanam dan interval pemberian air terhadap pertumbuhan bibit kelapa sawit tahap pre nursery. Penelitian ini dilaksanakan pada bulan Januari hingga Maret 2022 di lahan percobaan Jatimulyo Fakultas Pertanian Universitas Brawijaya. Menggunakan rancangan acak kelompok faktorial yang terdiri dari dua faktor yaitu 5 dosis komposisi media tanam dan 3 dosis interval pemberian air dengan 3 kali ulangan. Faktor pertama komposisi media tanam terdiri dari 5 dosis yaitu: 100% tanah, 75% tanah + 25% pupuk kandang, 50% tanah + 50% pupuk kandang, 25% tanah + 75% pupuk kandang, dan 100% pupuk kandang. Faktor kedua interval pemberian air terdiri dari 3 dosis dengan pemberian air 0,5 liter yaitu: 1 kali sehari, 2 kali sehari, dan 3 kali sehari. Pupuk kandang pada media tanam dapat mengurangi interval pemberian air. Bobot kering kelapa sawit umur 90 HST pada perlakuan komposisi media tanam 100% tanah dengan interval pemberian air 3 kali sehari dan komposisi media tanam 75% tanah + 25% pupuk kandang dengan interval pemberian air 2 kali memiliki nilai sebesar 3.96 dan 4.10 g serta memberikan hasil yang lebih baik dibanding perlakuan lainnya. Namun komposisi media tanam 75% tanah + 25% pupuk kandang dengan interval pemberian air 2 kali sehari lebih efisien dalam penggunaan air.

Abstract

Rice has a very important role for the sustainability of human life, this is because rice is one of the staple foods needed by humans. Based on data from the Central Statistics Agency (2022), rice production in the East Java region has decreased by 102,827.67t compared to rice productivity in 2021. So, to reduce imports is to carry out agricultural intensification, need to get superior varieties. These must through several stages starting from crossing to several stages of selection to get superior lines. These superior strains are then subjected to yield tests before being made into new superior varieties (NSV). The aims of this research were to determine the yields of 6 F7 strain of rice in irrigated lowland areas and their differences with the control varieties, and to obtain the selected F7 strain which had high yield characteristics. The yield component parameters observed included: plant height (cm), number of tillers (sum), number of productive tillers (sum), panicle length (cm), flag leaf shape, 50% dan 100% flowering age (DAP), and harvesting age (DAP), number of grains per panicle (sum), the number of panicles per clump (sum), filled grain (%), 1000 grain weight (g), yield (t/ha), and the difference in yield to the control variety (%). The outcome component parameters and results will then refer to the IRRI Standard Evaluation System of Rice (SES) 2013. The data obtained analyzed using ANOVA and if any significantly different results a further test used the Duncan Multiple Range Test (DMRT) at 5%.

Abstract

Beras merupakan bahan pangan utama bagi sebagian besar masyarakat Indoensia. Namun, dengan adanya perubahan iklim global memacu terjadinya fluktuasi hasil panen pada berbagai wilayah di Indonesia, termasuk Kabupaten Bojonegoro, Jawa Timur. Kabupaten Bojonegoro merupakan salah satu sentra produksi beras Jawa Timur yang didominasi oleh lahan sawah tadah hujan. Lahan sawah tadah hujan memiliki faktor pembatas yaitu air sehingga mengandalkan ketersediaan air dari air hujan. Fluktuasi ketersediaan air dapat diketahui dengan pendekatan neraca air dan dapat menjadi pertimbangan dalam menentukan periode tanam. Penelitian bertujuan untuk mempelajari ketersediaan air tanah dan penentuan periode tanam yang tepat untuk tanaman padi khususnya di lahan sawah tadah hujan. Penelitian dilaksanakan pada bulan Maret sampai Mei 2023 di Kabupaten Bojonegoro, Jawa Timur. Metode penelitian menggunakan metode deskriptif dengan pendekatan kuantitatif. Pengumpulan data dilakukan dengan mengumpulkan data primer (kapasitas lapang dan titik layu permanen) dan data sekunder (curah hujan dan suhu). Analisis data yang digunakan yaitu analisis neraca air lahan dan analisis penentuan periode tanam. Hasil penelitian menunjukkan bahwa ketersediaan air tanah di Kabupaten Bojonegoro mengalami kondisi surplus pada Desember I – April III dengan kadar air tanah mencapai kapasitas lapang, sedangkan pada Mei I – November III terjadi kondisi defisit dan kadar air tanah mengalami penurunan hingga mencapai titik layu permanen. Periode tanam untuk tanaman padi di lahan sawah tadah hujan dapat dilakukan pada 2 periode tanam. Periode tanam pertama dilakukan pada Desember I – Maret I dan periode tanaman kedua dilakukan pada Maret II – Juni II.

Abstract

The permanent export of soil nutrients by rubber latex systematically leads to a notorious impoverishment of the soil and consequently to a decrease in rubber production from the plantations. To do this, three studies on the mineral fertilization of rubber trees clones GT 1, PB 235 and PB 217 were carried out on plots belonging in South-west Côte d’Ivoire. The research was carried out under the ecological conditions of the area, on ferrallitic soils of granitic origin, to compare the effect of nitrogen, phosphate, and potassium fertilizers, applied alone or in combination, and different doses of N-P-K-Mg (8-4-20-4) on the radial isodiametric growth, yield, and nutrient content leaves of rubber trees. Fertilizer applications were carried out on elementary plots of 84 to 100 trees in two experimental designs (factorial and Fischer block). obtained revealed that the application of increasing doses of nitrogen, phosphate and potassium fertilizers had no apparent effect on rubber tree growth parameters trees. Small gains in rubber yields have observed, ranging from 1.5 to 5%, regardless of the rubber clone. These fertilizer applications, without prior knowledge of the physico-chemical status of the soil, have sometimes caused a decrease in production by creating or accentuating imbalances between soil minerals. Based on these results, we recommend that fertilization policies on rubber plantations should consider the level of local soil fertility and the nature, frequency, and timing of fertilizers applications, but without excess, to gain a better appreciation of the effect of fertilizers on the agronomic parameters of rubber trees.
