Abstract

The productivity of forage is strongly influenced by cutting height and interval of defoliation. Experiment was conducted at the Research Institute for Industrial Plants and Other Palm (BALITKA) Manado since June 2008 until April 2009. The objective of the experiment was to find out the effects of intensity and intervals of defoliation on dry weight production and the quality of nutrients. The experiment was arranged in factorial RCBD. The intensity of defoliation was based on cutting height, i.e. 5, 10, 15 cm, whereas the intervals of defoliation were 30, 45, 60 day and 456.54 Degree Days (DD). The data of dry weight production, leaf stem ratio, nutrient quality were collected. The results showed that there were significant effects of treatments on all parameters. Productivity of B. humidicolai terms of high dry weight yield, high leaf stem ratio and crude protein, low crude fiber and acid detergent fiber (ADF) content were found in the interaction of intensity 10 cm with the interval of defoliation among the vegetative development stage of 30 and 45 days, as well as the interval of defoliation based on heat unit accumulation of 456.54 DD. The research implies that a cutting height at 10 cm and interval of defoliation as mentioned above is ideal for B. humidicola. Utilization of growing degree days (GDD) to determine the appropriate time for defoliation is considerable under this experiment.Keywords: B. humidicola, defoliation, forage, nutrient, productivity

Abstract

The objective of this research was to study the morphology and physiology of jatropha leaves and its relation to photosynthesis. Research was conducted using Randomized Complete Block Design with single factor, i.e., leaf ages at the canopy with ten replications. The results showed that jatropha had phyllotaxy 5/13 with angular divergence 1380 . In early growing leaf enlarged sharply and then constant after 9 week, remaining green for 14 weeks. Chlorophyll a, b, and total achieved maximum at 9 week, i.e., 0.45 g/cm2 , 0.19 g/cm2 , and 0.62 g/cm2 , respectively. Photosynthesic rate was maximum at 6 week, i.e., 8.99 µmol/m2 /s, while number of stomata was maximum at 9 week (289.47 mm2 ). This finding implies that leaf number 11 to 13 or age 6 week after emergence could be used as reference for photosynthetic evaluation.

Abstract. Hastini T, Suwarno WB, Ghulamahdi M, Aswidinnoor H. 2019. Short Communication: Correlation and regression among rice panicle branches traits. Biodiversitas 20: 1140-1146. Panicle was a very important organ in rice since the grains are developed from the panicle branches. This study aimed to find out the information about the relationship among rice panicle branching traits using correlation and regression analysis. The trial was conducted at the IPB Research Station, Babakan, Bogor, Indonesia from December 2015 until April 2016. Twenty genotypes of lowland rice were used as treatments with three replications and arranged in a completely randomized design. The panicle branches traits were observed. The result showed that there was positively and a highly significant relationship among the panicle branches traits in general. Analysis using linear regression revealed that, in general, the total grains number per panicle showed the linear relationships with other traits, and only total grains number per panicle vs tertiary branches number, total grains number per panicle vs grains number of tertiary panicle branch, and total grains number per panicle vs the number of secondary branches per panicle branch showed the quadratic relationship. Among all rice panicle branching traits, the secondary panicle branches number had the highest contribution to the total grains number per panicle.

Abstract. Toyip, Ghulamahdi M, Sopandie D, Aziz SA, Sutandi A, Purwanto MYJ. 2019. Physiological responses of four soybean varieties and their effect to the yield in several saturated soil culture modification. Biodiversitas 20: 2266-2272. This study aimed to evaluate the production and physiological response of four soybean varieties in saturated soil culture (SSC), compared to conventional dry culture on tidal swamp soil growing media. Four popular varieties in Indonesia, namely Anjasmoro, Grobogan, Tanggamus and Malika, were planted on undisturbed intact tidal swamp soil from Jambi from November 2016 to March 2017 at Bogor. Randomized completely block design with two factors applied in this work, i.e. 4 varieties namely Anjasmoro, Grobogan, Tanggamus and Malika; and 9 culture methods such as dry culture as control of no SSC (i), 1 months SSC (ii), 1.5 months SSC (iii), 2 months SSC (iv), continuous SSC (v), 1 months SSC with water improvement (vi), 1.5 months SSC with water improvement (vii), 2 months SSC with water improvement (viii), and continuous SSC with water improvement (ix). The results showed that (i) pod production per plant was significantly affected by the interaction of both factors; (ii) different varieties lead to significant different of physiological response, i.e. photosynthetic rate, transpiration rate, stomatal conductance and water use efficiency; (iii) the variation of culture methods only showed a significant effect on photosynthetic rate, i.e. saturated soil culture with water improvement (SSC WI) showed 48% and 18% higher photosynthetic rate than dry culture and regular SSC methods, respectively. Pod production was positively correlated to photosynthetic rates and water use efficiency; and negatively correlated to transpiration and stomatal conductance. The highest number of pod production per plant was achieved by Malika variety that planted in 2 months SSC WI.

Abstract. Retnowati D, Solihin DD, Ghulamahdi M, Lestari. 2021. Next-generation sequencing-based Actinobacteria community associated with Callyspongia sp. from Kepulauan Seribu Marine National Park, Jakarta, Indonesia. Biodiversitas 22: 3702-3708. Sponges are sessile benthic filter-feeding animals, which harbor numerous microbes. The enormous community and abundance of sponge-associated actinobacteria envisage sponges as hot spots of microbes. The metagenomic approach with Next Generation Sequencing (NGS) technology was used to investigate the actinobacteria community of Callyspongia sp. collected from Kepulauan Seribu Marine National Park, Indonesia. Fourteen actinobacteria families were found associated with the sponge. Among them, Microbacteriaceae was the most dominant family. The community of actinobacteria was higher than that of the culturable method from our previous study. The research showed that a metagenomic approach using NGS technology reveals better information regarding the actinobacteria community associated with Callyspongia sp.

Abstract. Suwarti, Ghulamahdi M, Sopandie D, Trikoesoemaningtyas, Sulistyono E, Azrai M. 2022. Secondary trait and index selection determination for maize genotype selection in acidic tidal swamp environment. Biodiversitas 23: 4169-4179. Determining secondary traits as complementary selection in maize genotypes for abiotic stress environment is compulsory since yield-based selection usually provides biased result. This study aimed to obtain secondary traits for maize selection in an abiotic multi-stresses of Fe, Al, and temporary flooding environments of acid sulfate tidal swamp land using multivariate analysis. A total of 150 (un-repeated) maize inbred lines and five check genotypes in five replicates were arranged in a randomized augmented plot design in three environments to generate 525 single plots. Three types of environments based on irrigation regimes were applied on acid soil tidal swamp land to study the agronomic characteristics of maize genotypes in each environment. Saturated Cultivation Technology (SSC) was considered the optimal environment. Dryland treatment was the condition to let the irrigation only depend on rainwater. Temporary flooding treatment was carried out at five stages of different growth periods. Several steps of analysis were applied in this study by taking variance, and heritability was used as the basis for selections. The characters affected by treatments with medium to high heritability were then analyzed with correlation and pathway analysis. Seven selection indexes, SSI, GMP, YSI, YI, TOL, STI, and MP, that have a high correlation to yield in both optimum and stress environments, were applied simultaneity with the selected trait characters to screen the genotypes utilizing PCA biplot analysis. Venn analysis was used to group the genotypes based on the result of the analysis. Indices of STI, MP, GMP, and traits of rows number per ear and the weight of 6 ears were selected as secondary characters for the maize genotypes selection in Saturated Soil culture with temporary flooding stress. Meanwhile, STI, MP, and ear stand height were the selected characters in the dryland of acid sulfate tidal swamp land. Based on the combination of all secondary character selection, genotypes were grouped into five types of stress tolerance in SSC+TF and DL environments. Eight genotypes were tolerant to both SSC+TF and DL stress, and two genotypes were susceptible to both environments.

Abstract. Rohaeni WR, Suwarno WB, Susanto U, Trikosoemaningtyas, Ghulamahdi M, Aswidinnoor H. 2023. Genetic diversity, heritability, and accumulation patterns of Zn content in biofortified rice. Biodiversitas 24: 208-214. The study on zinc accumulation patterns in various rice organs is valuable information to support effective biofortified breeding. Research reports related to zinc accumulation have only been limited to seeds, while the pattern of zinc accumulation in each part of the plant has not been reported, especially for Indonesian rice germplasm. The study aims to provide information on the pattern of accumulation and genetic diversity of Zn content in rice plants. The experiments used a randomized complete block design (RCBD) with 3 replications and genotypes as a treatment. The genotypes were 29 lines of BC4F3 Inpari IR Nutri Zinc////Inpari 23, 5 lines of BC4F3 Inpari IR Nutrizinc////Sintanur, and 1 line of BC4F3 Inpari IR Nutrizinc////Inpari 35. A total of 6 varieties were used as checks. The Zn content of dehulled (brown rice) grains sample was measured using the Oxford Supreme8000 XRF machine with the Rice15 method that had been validated by the Inductively Coupled Plasma (ICP) method, while the analysis of the pattern of Zn content of several organs (seeds, leaves, stems, and roots) used the Inductively Coupled Plasma Optical Emission Spectrometry (ICP-IOS) method. The coefficient of genetic variation of the grain zinc content (GZn) was moderate and had high heritability criteria (H2bs = 0.83). Yield characters have a narrow coefficient of genetic variation and low heritability. There were differences in the pattern of Zn accumulation in plant organs between high GZn and low GZn genotypes. The distribution of Zn content in high GZn genotypes showed 26.4% in seeds, 13.7% in leaves, 39.3% in stems, and 20.6% in roots. The distribution of Zn content in low GZn genotypes showed 14.2% in seeds, 10.9% in leaves, 31.0% in stems, and 44.0% in roots. The results of this study indicate that a different breeding strategy is needed to develop new high-yielding rice varieties based on zinc accumulation patterns in cross-parents.

Abstract

Tidal lands have considerable potential for sugarcane expansion but are constrained by low phosphorus availability, soil acidity, and low productivity under conventional systems. Despite advances in water-saturated cultivation and the use of arbuscular mycorrhizal fungi (AMF), their combined effects with phosphate fertilization in sugarcane–soybean intercropping systems remain insufficiently understood. This study aimed to evaluate the effects of AMF inoculation and phosphate fertilizer rates, as well as their interaction, on crop productivity and land use efficiency. A field experiment was conducted on tidal land in Banyuasin, South Sumatra, using a randomized complete block design with two factors and three replications. The treatments consisted of AMF inoculation (without and with local AMF derived from maize) and phosphate fertilizer rates (0, 36, 72, and 108 kg ha⁻¹ P₂O₅) under a 4-month water-saturated cultivation system. Productivity and land equivalent ratio (LER) were used as key indicators. The results showed that the interaction between AMF inoculation and phosphate fertilizer rates was not significant for sugarcane productivity. However, AMF inoculation significantly increased the productivity of both sugarcane and soybean in intercropping and monoculture systems. In contrast, phosphate fertilizer rates did not significantly affect land use efficiency. The intercropping system consistently produced LER values greater than 1 (1.55–1.73), indicating higher land-use efficiency than monoculture systems. These findings demonstrate that AMF inoculation plays a more important role than phosphate fertilization in improving crop productivity under water-saturated tidal conditions.

Abstract

This study aimed to analyse the effect of exopolysaccharide-producing (EPS) bacteria on rice growth and yield under mercury stress induced by applying 40 mg HgCl? to each bucket containing 10 kg of soil. The research was conducted on a plastic-house scale in Sijunjung Regency, West Sumatra, Indonesia, from December 2025 to March 2026. The experimental design used was a two-factor factorial completely randomized design. The first factor was rice variety (IR 64 and Sertani). The second factor was no bacterial treatment versus bacterial consortium treatment (Priestia megaterium, Priestia aryabhattai, Pseudarthrobacter defluvii, and Burkholderia vietnamiensis). Each treatment was replicated three times. The results showed that there was no interaction between bacterial treatment and the tested rice varieties. In the IPB 9G and Sertani cultivars, the bacterial consortium increased tillers per hill, total productive tillers per hill, root dry weight, and shoot dry weight. It also increased 1,000-grain weight, filled-grain weight per panicle and per hill, and the number of filled grains per panicle. Compared with the control, the bacterial consortium treatment increased filled grain weight per hill by 25.76% in the IPB 9G variety and by 60.77% in the Sertani variety. Based on PCA, the variables contributing to PC1 were panicle length (PL) (0.925), PW (0.869), and PH (0.859). Correlation analysis showed that panicle weight (PW) and number of filled grains per panicle (NFGPP) (r = 0.98).
