Abstract

Research on Trichoderma sp. isolates derived from the roots of the wild orchid Paphiopedilum javanicum for application in commercial orchid acclimatization is still limited. The study aimed to determine the optimal dose of Trichoderma sp. isolates to grow hybrid Dendrobium discolor >< lasianthera seedlings at the acclimatization stage. The study was conducted using a Complete Randomized Block Design (CRBD) with non-factorial experiments and repeated 4 times as blocks. Treatments in the form of Trichoderma sp. doses were 0 g, 2 g, 2.5 g, 3 g, and 3.5 g. Trichoderma sp. doses significantly affected the increase in plant height, the amount of chlorophyll a, and root infection. A dose of 2.46 g was the optimal dose that gave a Trichoderma infection rate in the roots of 100%. A dose of 2.5 g gave the best results in increasing plant height (0.625 cm). A dose of 3.5 g gave the best results in chlorophyll a (4.55 mg/l). Trichoderma has the potential to be propagated into a biofertilizer product to support the growth of commercial orchids during acclimatization.

Abstract

The increasing demand for sugar is not accompanied by increased productivity of sugarcane, the primary raw material for making sugar. Utilizing dry land is one strategy to increase sugarcane productivity. Poor soil fertility caused by limited water and nutrients can affect the growth and productivity of sugarcane. It can be solved by using inorganic fertilizers combined with biological fertilizers such as Arbuscular Mycorrhiza in the planting media. One effort to increase the productivity of sugar cane plants is to improve the quality of sugarcane seedlings. The speed of growth at the beginning of the seeding period is determined by soil fertility and the variety of sugarcane plants used. This research was conducted from September to December 2023 at the Patrang Greenhouse, Jember Regency. This experiment was conducted using Factorial Completely Randomized Factorial Design (CRD) 2 factors with five replications. Factor 1 is the administration of mycorrhizal doses consisting of 4 levels, namely: Aₒ (0 grams), A₁ (5 grams), A₂ (10 grams), A₃ (15 grams). Factor 2 is the variety consisting of 2 types, namely, as follows: V₁ (Bulawang variety) and V₂ (PS 862 variety). The interaction of mycorrhizal dose treatment and the sugarcane variety significantly affected the plant's variable fresh weight. The combination treatment with a mycorrhizal dose of 15 grams applied to the PS 862 (A3V2) sugarcane variety gave the best results.

Abstract

This study examines the effectiveness of Ganoderma sp. in decomposing lignin in herbaceous plants. The study was conducted in a greenhouse at the Faculty of Agriculture, Sriwijaya University, with temperatures ranging from 28-30oC and humidity reaching 70-80%. The test plants consisted of uwi (Dioscorea alata) and talas (Colocasia esculenta), and oil palm seedlings were used as a comparison. The parameters observed included the level of decay and mycelium viability after inoculation. The results showed that the highest level of decay occurred in taro, reaching 65.22% in sterilized soil and 52.56% in unsterilized soil, while uwi experienced decay of 33.9% and 33.03%. The viability of Ganoderma sp. mycelium remained high (>70%) in all treatments. This indicates a strong ability to adapt to various environmental conditions. Thus, the study shows that the ligninase activity of Ganoderma sp. contributes significantly to decomposition without reducing the viability of the Ganoderma sp.

Abstract

This research aims to determine the effects of fertilization timing and weed control on the growth and yield of Sponge Gourd, and to identify the best timing for optimal growth and yield. The research was conducted from April - July 2024 on a farmer's land at Palangka Raya, Central Kalimantan. The method used was a Randomized Block Design (RBD) with 10 treatment combinations and 3 groups. Treatments included fertilization with Gandasil B at 20 and 23 days after planting (DAP), 25 and 28 DAP, and 30 and 33 DAP, along with weed control intervals of 7, 14, and 21 days. Observed variables were plant length, number of leaves, number of branches, fruit diameter, fruit length, fresh weight of sample fruit, number of sample fruits, fresh weight of fruit per plot, and number of fruits per plot. The results showed significant differences in fertilization timing and weed control on plant length, number of leaves, number of branches, fresh weight of sample fruit, number of sample fruits, fresh weight of fruit per plot, and number of fruits per plot, but no significant differences in fruit diameter and length. Weed vegetation analysis indicated that babadotan weeds had the highest Summed Dominance Ratio (SDR) of 26% before land preparation, and jukut pendul weeds had the highest SDR of 45% post-harvest. Treatment G4, with fertilization at 25 and 28 DAP and weed control every 7 days, was the best treatment. Observations showed that all variables in treatment G4 had the highest average values.

Abstract

Rice husk biochar has the potential to enhance the growth of sweet corn plants during the dry season due to its water-holding capacity, high organic-C and CEC (Cation Exchange Capacity) content, and its ability to improve soil biological quality. This research was conducted with the main objective of testing the effect of rice husk biochar application on the agronomic characteristics of sweet corn grown on a farmer's field in Togaso village, Galang District, Tolitoli Regency, Central Sulawesi, during the dry season. The study employed a Randomized Block Design (RBD) with four treatment levels and four replications, namely b0 (0 tons ha-1), b1 (5 tons ha-1), b2 (10 tons ha-1) and b3 (15 tons ha-1) biochar. The results of the study showed that the application of rice husk biochar had a significant effect (p<0.05) on the observed parameters, namely the increase in plant height, number of leaves, stover dry weight (or: shoot dry weight), Leaf Area Index (LAI), fresh cob weight with and without husks, and production per hectare, but had no effect on the Net Assimilation Rate (NAR) parameter of sweet corn plants in the dry season.

Abstract

Climate change in Indonesia has led to an increase in abiotic stress, particularly drought, which significantly affects sugarcane productivity. This research was conducted from 2024 to 2025 at the Laboratory of Molecular Biology and Biotechnology, Waste Management Unit, and Integrated Laboratory, University of Jember. The aim of this study was to evaluate the agronomic, physiological, and biochemical responses of five sugarcane varieties under drought stress conditions. The results showed that drought stress had varying impacts depending on the tolerance of each variety. The drought-tolerant transgenic variety (NXI4T) exhibited more stable responses, as indicated by lower drought and leaf rolling scores, higher soil water content (SWC) and relative water content (RWC), and relatively stable levels of chlorophyll, phenolics, and flavonoids. In addition, lower H₂O₂ accumulation and a stronger root system supported better adaptation to drought conditions.

Abstract

The development of superior varieties requires accurate genetic information, especially on the traits that will be used as selection criteria. Variance components (genetic variance, environmental variance, and phenotype variance) and heritability values are the genetic information for the selection process. Selection will generally be effective if the characters used as selection criteria have heritability values that are included in the high category (> 50%). The objective of this research for estimating the components of variance and heritability in a broad sense for a number of agronomic characters in the second generation (F2) population of cayenne pepper from the hybridization between Capsicum frutescens L. and Capsicum annuum L.  The genetic materials consisted of two parental lines, P1 (Bonita IPB) and P2 (Perisai IPB), each represented by 20 individual plants, and 150 individuals from the F2 generation. Estimation of variance components and broad-sense heritability was performed using the Mahmud–Kramer method. The results of the study showed that the diversity in the F2 population was higher than in both parents. This is indicated by the variance values for all characters being greater than both parents. Traits such as plant height, canopy width, stem diameter, day of flowering, fruit weight per plant, number of fruits per plant, fruit weight, fruit length, and fruit diameter showed high heritability values, while day of harvesting showed moderate heritability. These heritability estimates suggest that effective selection can be focused on traits with high heritability, thereby increasing selection efficiency and enabling favorable genetic progress in subsequent generations.

Abstract

The utilization of swamp land in cultivating rice plants has obstacles, especially the presence of abiotic stress, which are submersion in the vegetative phase and drought in the generative phase which impacts productivity. The use of superior varieties that can withstand submersion and drought stress can be a solution in increasing rice productivity in swamp land. This study aims to evaluate the growth and production performance of BC2F4 generation accessions, in shallow swamp land. This study was conducted in Pelabuhan Dalam Village, Pemulutan District, Ogan Ilir Regency, South Sumatra from June to October 2024. This study used a Randomized Block Design using accessions resulting from BC2F4 crosses, including; T1, TR1, T2, TR2, T3, and TR3, as well as Inpago 5 varieties (recipient parents) and IR 64 (popular varieties). The results showed that all BC2F4accessions showed better growth and yield performance compared to Inpago 5. The T3 variety showed the highest productivity at 3.25 tons/ha. In addition, the Pearson correlation showed that productivity was influenced by the variables of the number of tillers (0.58), productive tillers (0.68), and grain weight per panicle (0.89).
