Abstract

Potassium is an essential macronutrient that supports major physiological processes in plants and strongly influences soybean productivity. This study aimed to evaluate the effects of different potassium fertilization levels on plant physiology, yield performance, and seed nutritional composition in two soybean varieties, ‘Dena 1’ and ‘Denasa 1’.The research employed a factorial completely randomized group design with five potassium fertilizer levels (0, 15, 30, 45, and 60 kg K2O/ha) and two soybean varieties (‘Dena 1’ and ‘Denasa 1’), with three replications. The results showed that the potassium dose significantly affected plant height and leaf number but did not influence photosynthetic rate or stomatal conductance. The ‘Dena 1’ variety exhibited better growth, greater leaf greenness, and faster generative development than ‘Denasa 1’. The optimal potassium dose of 45 kg/ha improved yield components, resulting in a 30.7% increase in seed weight and a 45.8% increase in the number of filled pods compared with the control. A positive correlation was found between plant potassium content and key physiological traits, such as photosynthesis and transpiration rates. Seed nutrition analysis showed that soybean varieties significantly influenced nitrogen and phosphorus levels at the R7 and R8 stages, whereas the potassium fertilization dose had no significant effect on seed nutrient concentrations. Nutrient levels increased from R6 to R7 before declining at R8, reflecting nutrient redistribution during seed filling. Overall, the results suggest that applying 45 kg K2 O/ha is an effective fertilization rate for enhancing soybean physiological performance and yield, while varietal characteristics remain the primary factor shaping seed nutritional composition.

Abstract

Eighteen Indonesian new plant type (NPT) of rice varieties and lines were evaluated in a ratoon system. The results showed that ratooning ability was related to the vegetative growth prior to harvest, which gave high ability ratoon growth. New plant type varieties and several lines of rice had better vegetative growth and produced higher ratoon than other genotypes. Ratoons started to develop 2-7 days after harvest, with an average number of leaf 2-4 per tiller. Number of productive tillers of ratoon ranged from 6.0 to 30.0 per hill, with number of grain per panicle ranged from 38.0 to 228.2, and grain weight per hill of ratoon 10.4 to 31.2 g, dependent on genotypes. Maturity of ratoon was also dependent on genotypes. On average, maturity was 68 days after harvest of the main crop. Grouping of ratooning ability based on hierarchical cluster analysis resulted in three groups, namely nine genotypes had high potential, fi ve genotypes had medium potential, and four genotypes had low potential. This study indicated that ratoon is potential to increase rice planting index in Indonesia. The genotypes with high ratoon ability need to be evaluated for agronomic performance in the fi eld.

Abstract

Amorphophallus variabilis Blume, a member of Araceae, is a native tuber crop in Java, Madura and Kangean Islands,Indonesia. The plant showed high variations in morphology. However, genetic variations at molecular level have not beenwell studied. Amplified fragment length polymorphism (AFLP) was carried out using 8 primers combination of EcoRI andMseI on 78 accessions collected from 28 sites in Java, Indonesia. Results showed that AFLP markers able to generatepolymorphism among accessions. A total of 220 polymorphisms were found. The differences among accessions at the geneticlevel were high, and 5 clusters were constructed. Grouping was independent of geographical origin, similar to clustering ofmorphological characteristic of flowers as in the previous report. Accessions from one site composed of one to four differentcluster groups, showed that variation in single site was observed. Regarding conservation program of the A. variabilis innatural population, it is reasonable to protect one bigger site rather than many small sites, but it should be recommended tomaintain conservation areas in several districts. Further study on population structure should be carried out to explain suchvariability.

Abstract

Estimation on oil palm production is important for company planning. However, there are only few studies have been conducted in Kalimantan. The objective of the study was to identify agronomic and agroecological factors determined production of oil palm in Kalimantan. The study was conducted at PT Ladangrumpun Suburabadi, Minamas Plantation Angsana Estate, Tanah Bumbu District, South Kalimantan, Indonesia from February 15 to June 15, 2010. Data were collected from the company, government institutions and interviews with the company staffs. Results showed that seven parameters signifi cantly determined estimation of oil palm production. Out of 18 possible linier models, 6 models showed good fi t as predictor. The best modeling as predictor was determined by current plant age (in months), fertilizer application at 18 months before harvest (MBH), relative air humidity at 6 MBH (%), light intensity at 18 MBH (%), rainfall at 6 MBH (mm), level of water defi cit at 24 MBH (mm) and number rainy day at 18 MBH (days). It was expressed in equation Y = 3.15 + 0.010 age -0.016 fertilizer -0.016 light intensity -0.005 water defi cit -0.015 number of rainy day. This fi nding implies that recording data of agronomic and ecological factors are important for production estimation. Eventhough the model is best fi t to the study site, however, it needs further verifi cation when applied in larger area of the other sites in Kalimantan.

Abstract

Background: Habanero Francisca pepper (Capsicum chinense Jacq.) is an ornamental chili cultivar whose seedling quality is strongly influenced by the composition of the growing medium. Rice husk charcoal, cocopeat, and bamboo compost are commonly used nursery substrates because they improve water retention, aeration, and nutrient availability; however, information regarding their combined use for Habanero Francisca pepper seedlings remains limited. This study aimed to identify an effective growing medium composition based on substrate physical properties and seedling morphological responses. Methods: A randomized complete block design with one factor (growing medium composition) and four treatments was applied: M0 (commercial growing medium, control), M1 (rice husk charcoal: cocopeat: bamboo compost = 2:1:1), M2 (1:2:1), and M3 (1:1:2). Substrate properties, including bulk density, particle density, and porosity, were measured. Seedling growth was evaluated through plant height, leaf number, root length, root number, total fresh weight, and total dry weight. Data were analyzed using the F-test followed by Duncan’s Multiple Range Test at the 5% significance level. Findings: The composition of the growing medium significantly affected plant height, root length, root number, total fresh weight, and total dry weight, but had no significant effect on leaf number. The M2 treatment produced the highest porosity (82.11%) and superior seedling performance, with plant height of 9.55 cm, root length of 10.36 cm, total fresh weight of 0.55 g, and total dry weight of 0.07 g, compared with 5.69 cm, 4.05 cm, 0.25 g, and 0.01 g, respectively, in the control treatment. Higher porosity in M2 likely enhanced root development and resource uptake, resulting in greater biomass accumulation. Conclusion: A cocopeat-dominant medium (1:2:1) is the most effective composition for producing high-quality Habanero Francisca pepper seedlings, supporting the use of agricultural residues as a renewable, resource-efficient alternative to commercial peat-based media in pepper nurseries. Novelty/Originality of this article: This study is the first to integrate substrate porosity assessment with morphological performance evaluation to determine an effective nursery medium specifically for Habanero Francisca pepper, a cultivar for which such information has not previously been reported.

Abstract. Tajuddin M, Santosa E, Sopandie D, Lontoh AP. 2020. Characteristics of growth, flowering and corm yield of iles-iles (Amorphophallus muelleri) genotypes in third growing period. Biodiversitas 21: 570-577. Iles-iles (Amorphophallus muelleri Blume) is an emerging crop for producing glucomannan, and it is predominantly cultivated in agroforestry systems. The study aimed to evaluate characteristics of growth, flowering, and production of genotypes in the third growing period in order to develop new clones. The experiment used 2-year-old corm of ten genotypes, i.e. BKB, CF, CR, LSP, SB, SBM, SG-BKK, SGH, SR and STS. The corms were planted in June 2018 to May 2019 in the field under 45% artificial shading net. Plant growth was evaluated on weekly basis from bud emergence until dormant. Flowering rate was ratio the number of corms with flower to number of planted corms in each replication. Corm dry mass was measured after harvest, which was conducted at dormant stage at 46 weeks after planting. Candidate clone was selected from the highest total score of five criteria i.e. flowering rate, corm shape, corm healthiness, marketable yield, and total yield. Results demonstrated that genotypes exhibited variation in growth, flowering rates, and yield. Based on emerging time, three genotypes (SB, SGH, SG-BKK) were classified as early emergence, five genotypes (CF, CR, LSP, SBM, STS) as a medium, and two genotypes (BKB, SR) as the late emergence. All genotypes produced inflorescence at rate 1 to 52%, and 3 genotypes (CF, CR, STS) had flowering rate >20%. Five genotypes (CR, LSP, SBM, SGH, STS) had an average corm weight > 1500 g. CR and SBM genotypes produced the largest average corm weight, i.e., 2,509.33 g and 2,129.25 g, respectively, while the BKB produced the smallest one (912.94 g). All genotypes had similar dry mass content, i.e., 18.73-20.70%. The scoring evaluation recommended CR, SBM, and STS genotypes as candidates of new clones with productivity > 30 ton/ha. It needs further evaluation of selected clones in the farmer production field.

Abstract. Maretta D, Sobir Helianti I, Purwono, Santosa E. 2020. Genetic diversity in Eddoe Taro (Colocasia esculenta var antiquorum) from Indonesia based on morphological and nutritional characteristics. Biodiversitas 21: 3525-3533. Low yield uniformity and quality due to genetic performance become negative incentives to farmers in Eddoe Taro production. However, genetic evaluation is rarely been reported in this taro type in Indonesia. In this study, 14 eddoe genotypes collected from different regions in Indonesia were evaluated to develop a diversity map for crop improvement and future breeding activities. The genotypes were planted in the open field from September 2018 to March 2019 at the experimental station belonging to LAPTIAB-BPPT, PUSPITEK at South Tangerang District, Indonesia. Morphological and nutritional characters were accessed on the shoot and underground parts. The genotypes exhibited variation in 38 out of 48 characters in which 12 quantitative characters were distinct including oxalate level. The study revealed three findings: (i) Characters related to growth and yield had high genotypic variance coefficients, i.e., sheath length, total petiole length, plant height, number of suckers, corm and cormels weight, (ii) Genotypes clustered into two separate groups as introduced and landraces, and (iii) Landraces had high genetic variation leading to speculation of high clonal variation. Considering the findings, accession S6, S7, S18, S30, and S36 are recommended for further studies in crop improvement purposes.

Abstract. Hidayatullah CSR, Santosa E, Sopandie D, Hartono A. 2020. Phenotypic plasticity of eddoe and dasheen taro genotypes in response to saturated water and dryland cultivations. Biodiversitas 21: 4550-4557.  The phenotypic plasticity of dasheen and eddoe taro genotypes was evaluated based on growth and yield characters to select proper genotypes in response to climate change. The study was conducted at the Leuwikopo Experimental Farm, Bogor, Indonesia from May to October 2019. Dasheen (Talas Sutra and Talas Bentul) and eddoe genotypes (S28 and S19) were planted in saturated water cultivation (SWC) and dryland cultivation (DC). DC relied on rainwater, and SWC was manipulated dryland by flooding. SWC promoted vigorous growth and tuber weight, irrespective of genotypes. Increasing taro biomass production in SWC was supported by higher photosynthetic rate, leaf number, and size. Dasheen genotypes produced higher tuber weight than the eddoe in SWC, conversely, the eddoe tended to produced heavier tuber than the dasheen in DC; indicating phenotypic plasticity is strongly affected by soil moisture and genotype. The dasheen had more plastic growth and yield characters to soil moisture than the eddoe genotypes, with plasticity level, ranging from low to very high. Taro had high resiliency to multiple abiotic stresses, e.g. flood, and drought. Considering the marketable value of the yield, dasheen and eddoe genotypes are recommended in flooding and drought-prone areas, respectively.
