Abstract

Wheat is a cereal crop that can grow well in tropical areas only at high altitudes. However, the limited area of the highlands means that wheat development is directed at the lowlands, so plant breeding efforts are needed to obtain genotypes that are adaptive in the lowlands, one of which is through gamma ray irradiation. This research aims to identify the performance of agronomic characters of several wheat genotypes resulting from gamma irradiation planted in the lowlands. This study used a Randomized Block Design (RBD) with 2 factors, namely the first factor was wheat variety (Dewata/L, Basribey/I, and G-21/F) and the second factor was irradiation dose (0 Gy, 100 Gy, 200 Gy and 300 Gy). The data analyzed using F test at 5%. The treatment means were further compared and separated by using the Duncan Multiple Range Test (DMRT) at 5%. The research results showed that the wheat variety treatment had a significant effect on plant height and leaf area of wheat, while the gamma ray irradiation treatment and the combination of the two treatments had no significant effect on all parameters observed, but showed diversity in agronomic characters.

Abstract

Insect hotels are a medium for the conservation of beneficial insects that can be developed in the community. Insect hotels are developed to provide a safe and comfortable habitat for insects, especially beneficial insects. This research aims to determine the types and populations of insects in insect hotels across different types of land, namely rice fields, plantations, greenhouses, and agroforestry. The research was conducted by installing insect hotels in various types of agricultural land for one month, with observations made once a week. The observed insects in the insect hotels were then identified, and the average population count was calculated. The research results show that the types of insects obtained from the installation of insect hotels in rice fields, plantations, and greenhouses belong to the Formicidae family, while in agroforestry land, several types of insect families were found, namely the Coccinellidae, Anthocoridae, Aradidae, Tenebrionidae, Dolichopodidae, and Formicidae families. The Formicidae family was found in all agricultural lands with different average populations. The Formicidae family with the highest average population was found in the plantation land with a value of 4.75 individuals, while the lowest average population was found in the greenhouse and agroforestry land with a value of 0.5 individuals. The Tenebrionidae family was the family with the highest average population found in agroforestry land with an average of 2.75 individuals, while the family with the lowest average population found in agroforestry land was the Formicidae family with an average value of 0.5 individuals.

Abstract

Sorghum is a cereal plant that has great potential to be developed in Indonesia as a food crop, feed, and biofuel. Sorghum breeding has resulted in a variety of adaptive lines being developed on dry land. This study aimed to determine the adaptability of sorghum in dry land of Palembang City. The research was conducted in Sukamulya Village, Palembang City, from May to October 2021.  The experimental design was arranged using  non-factorial Randomized Block Design with treatment of various sorghum lines from IPB breeding, consisting of 11 various lines: A-18-12-7-5 (G1), A-19-18-3-8 (G2), B-14-25-5-6 (G3), B-043-16-5-5 (G4), B-4-6-7 (G5), C-248-16-5-3-4 (G6), C-267-18-18-2-7 (G7), C-375-17-5-9 (G8), Bioguma 1 (G9), Super 6 Agritan (G10), dan Samurai 2 (G11),  each treatment was repeated 3 times.  The Honestly Significance Difference (HSD) test showed that there were significant differences in plant height, number of leaves, flowering age, harvest age, panicle wet weight, panicle dry weight, 1000 seeds weight, and productivity.  C-375-17-5-9 and  Bioguma 1 were lines which were able to adapt well on dry land, because overall they showed better agronomic characters than other sorghum lines. The correlation between the characters of the growth component and the yield component showed that the number of leaves, panicle weight and 1000 seeds weight could be used as estimating indicators in selection activities for the improvement of sorghum yield.

Abstract

Vermicompost is the product of organic matter decomposition by earthworms and has great potential as an environmentally friendly fertilizer. It contains natural growth hormones, enzymes, and active microorganisms, and is free from harmful pathogens and heavy metals, making it safe for both soil and plants. Alfisol soils, which are typically low in organic matter and essential macronutrients such as nitrogen (N), phosphorus (P), and potassium (K), require organic inputs to improve their fertility. This study aimed to evaluate the effects of vermicompost and manure on nutrient availability and sweet corn yield in Alfisols. The experiment was conducted using a completely randomized block design with treatments combining various doses of vermicompost and manure. Observed parameters included soil chemical properties, plant growth, and yield components. The results showed that the application of vermicompost at a dose of 1 ton/ha was not significantly different from 2 tons/ha of manure, but both treatments differed significantly from the control. The combined treatment of NPK and vermicompost (1 NPK + 2 vermicompost) increased nutrient availability and uptake, as well as sweet corn yield (total N: 0.68%, available P: 7.76 ppm, available K: 1.78 me/100 g, cob weight: 240.5 g). These findings confirm that vermicompost, as an organic nutrient source, is effective in supporting sustainable agricultural practices in marginal soils such as Alfisols, while reducing dependence on inorganic fertilizers.

Abstract

The success of rice production is largely determined by the quality of the seeds and proper management during storage. The study aims to evaluate the influence of storage methods on the quality of local rice seeds in West Bangka, as well as the chemical content of 8-month storage seeds. The method used is an experiment with a Complete Random Design (CRD) design. The main treatment is the storage method of seedling tubs and panicles. Six local rice accessions in Bangka, namely Mukot, Jawa, Ungu, Pulut Hitam, Balok Merah, and Mayang Hutan, were used as research materials. The observed characteristics include germination power, maximum growth potential, germination rate, and proximate content in seeds. The results showed that the storage method in the nursery was able to maintain the characteristics of germination, moisture content, vigor index, growth synchronicity and dry weight of normal sprouts. The storage method of panicles is able to maintain the characteristics of the seeds, such as maximum growth potential, germination rate and growth speed. Jawa rice accession is the accession that is most able to maintain seed quality with germination power (72.33%) and has better characters in parameters such as maximum growth potential, growth synchronicity, and germination rate after storage. Chemical content analysis showed that seeds stored using the bean sprout method had a more stable and lower moisture content than storage in a nursery tub. The carbohydrate content of seeds stored by the malai method is higher, which supports the germination process that requires high metabolism.

Abstract

Garlic has been recognized as a medicinal plant. The most efficacious part of garlic is the bulb, because it contains the compound allicin, a substance that functions as an antibiotic and can boost the immune system. Allicin is an organosulfur compound. This study aims to examine the effect of sulfur application on increasing organosulfur content in garlic plants cultivated with phosphate fertilization. This study used a factorial Randomized Complete Group Design (RCGD), consisting of two treatment factors, which are the provision of phosphate fertilizer in three levels (S1: SP-36 150 kg/ha, S2: SP-36 200 kg/ha, S3: SP-36 250 kg/ha) and sulfur fertilizer in three levels (B1: 40 kg/ha, B2: 80 kg/ha, B3: 120 kg/ha). From the experiment, the results showed that the application of sulfur had a very significant effect on plant height and number of leaves and gave differences in organosulfur content in tubers although not significant. There was also no significant difference in the application of phosphate fertilizer and sulfur on organosulfur content in garlic bulbs. The highest organosulfur content in the bulbs was 341.12 mg/kg obtained in the treatment of SP-36 150 kg/ha and sulfur as much as 80 kg/ha.

Abstract

Coffee is a strategic plantation commodity with increasing global demand. However, its productivity remains relatively low due to pest and disease infestations. One of the major pests causing substantial yield losses is the coffee berry borer (CBB), with infestation levels reaching 50–60% and yield reductions of 25–49%. This study aimed to identify the genera of CBB based on morphological characteristics. Infested coffee berries were collected from the field, followed by laboratory observations and morphological identification using the methods of Browne and Le Pelly. The morphological data were then compared with insect specimens from the collection of the Centre for Agriculture and Bioscience International (CABI). The results revealed morphological differences between the CBB specimens collected from the field and those of the Hypothenemus genus in the CABI collection. Three genera were identified Hypothenemus, Chryphalus, and Stephanoderes, each exhibiting distinct morphological features. The Hypothenemus imago is dark black with a three-segmented antenna ending in a rounded club; Chryphalus has a slightly black coloration, an elliptical head crown extending backward, a very small body size (<1 mm), and a soft, fragile texture; whereas Stephanoderes shows light to dark brown coloration, a prominent mouthpart resembling a shrimp head, a four-segmented antenna with a cylindrical tip, and evenly aligned setae on the wing surface. The intensity of infestation varied among the genera: Hypothenemus caused 35–77% damage in Robusta coffee, Chryphalus 10–25% in Robusta coffee, and Stephanoderes 33–50% in Arabica coffee.

Abstract

Drought stress is one of the abiotic factors that can inhibit plant growth and yield. This study aims to assess the effect of drought stress on the physiological characteristics of pasak bumi (Eurycoma longifolia, Jack). This study used a completely randomized design with two treatments, namely P0 = daily watering (control) and P1 = drought stress for two days. Each treatment consisted of 15 plants; there were 30 sample plants. Parameters observed included chlorophyll content, stomatal conductance, transpiration rate, photosynthetic rate, and Water Use Efficiency. The results of this study showed that drought stress decreased chlorophyll content (5.81%), stomatal conductance (10.34%), transpiration rate (18.73%), photosynthetic rate (3.78%), and water use efficiency (33.127%) compared to control plants. Eurycoma longifolia Jack exhibits an adaptive physiological response to drought stress, characterized by moderate reductions in chlorophyll content, photosynthesis rate, and stomatal conductance while maintaining efficient photosynthetic activity. Although water use efficiency declined significantly, the findings indicate effective compensatory mechanisms, positioning this species as a potential candidate for cultivation under water-limited conditions.
