Abstract

Bambara groundnut (Vigna subterranea (L.) Verdc) is recognized for its nutritional benefits and ability to improve soil fertility through nitrogen fixation. This study evaluated growth performance, nitrogen dynamics, and seed quality across six landraces: Tasikmalaya, Sukabumi, Sumedang, Small Sumedang, Bogor, and Gresik. The experiment was conducted at IPB University’s Sawah Baru experimental field from July 2022 to March 2023. The experiment used a randomized complete block design with four replications. The measured variables were petiole length, number of petioles, number of leaves, leaf greenness, plant dry weight, nitrogen content, nitrogen uptake in roots, petioles, leaves, and pods, protein content in pods, and seed quality. Results showed significant variation among landraces. Gresik exhibited superior vegetative growth and dry biomass, while Tasikmalaya had the highest pod nitrogen (4.58%) and protein content (28.03%), indicating efficient nitrogen assimilation. Nitrogen analysis revealed distinct uptake patterns across landraces, particularly with Gresik, where a rapid increase in nitrogen suggests that this landrace is well-suited to environments where nitrogen is efficiently fixed and mobilized toward reproductive growth. Sukabumi and Bogor showed the highest germination rates (94%), and Bogor and Gresik had the highest vigor indices (76% and 72%). Overall, Gresik is recommended for balanced performance in growth and seed vigor, while Tasikmalaya is optimal for protein yield and nitrogen use efficiency.

Abstract

Sweet corn (Zea mays L. var saccharata) is a valuable crop whose productivity depends not only on macronutrients but also on micronutrients such as zinc (Zn) and boron (B), which play essential roles in plant physiological processes. However, the effectiveness of foliar-applied micronutrients in sweet corn cultivation under tropical conditions remains insufficiently studied. This research aimed to evaluate the agronomic effectiveness of a micronutrient fertilizer containing Zn (5.46%) and B (3.59%) when combined with reference and reduced doses of NPK fertilizer. The experiment was conducted from February to May 2025 at the Sindangbarang Experimental Farm, IPB University. This experiment was conducted using a randomized complete block design with four treatments, namely control (no fertilizer), reference fertilizer, reference fertilizer + 1 dose of micronutrient fertilizer, and ¾ dose of reference fertilizer + 1 dose of micronutrient fertilizer, with six replications. Results showed that micronutrient application significantly enhanced vegetative growth and yield components compared to the control. The combination of reference NPK and one dose of micronutrient fertilizer produced the highest productivity, with a 78.8% increase over the control and a relative agronomic effectiveness (RAE) value of 114.5%, indicating a 1.14-fold improvement over the reference treatment. These findings suggest that integrating Zn and B into fertilization strategies can enhance sweet corn performance and support more efficient nutrient management in tropical agroecosystems.

Abstract

Quality seeds are crucial for successful sweet corn production. Various factors influence seed quality, including harvest time and initial water content. Therefore, understanding the interaction between harvest time and initial water content is essential for optimizing the quality of sweet corn seeds. This study aims to determine the optimal harvest time and initial water content for assessing the seed quality of four sweet corn genotypes: T13.1.8, SB13.1.3, T8.3.6, and T8.3.2. The experiment employed a factorial Randomized Complete Block Design (RCBD) with two factors. The first factor, harvest time, consisted of five levels (73, 76, 79, 82, and 85 days after planting [DAP]). In contrast, the second factor was the initial water content for seed testing, categorized as harvest water content and 10-12% moisture content. Each treatment was replicated three times, resulting in a total of 30 experimental units. The findings indicated that the sweet corn genotypes T13.1.8 and SB13.1, which were harvested at 76 to 82 hours after sowing (DAP) and had an initial water content of 10 to 12%, represented the optimal treatment combination. These genotypes exhibited germination rate and vigor index variables ranging from 92.7 - 100% and 70.67 - 96.67%. Sweet corn genotypes T8.3.6 and T8.3.2 can be harvested between 79 - 85 DAP with an initial water content of 10-12% to obtain seeds with a germination rate ranging from 86.00 - 98.67% and a vigor index of 58.00 - 86.67%. The study results can be used as a recommendation for seed producers to apply the harvest time and water content according to the genotype used, to ensure that the seeds produced have high viability and vigor.

Abstract

Suboptimal environmental conditions cause low imbibition rate in maize plants, thus disrupting enzyme activation and food availability for the sprouts, and inhibiting the germination process. This study aims to provide a better understanding of the imbibition pattern and physiological characteristics of germination, hopefully obtaining useful information in the development of seed processing techniques and more efficient agricultural technology. The maize seeds used in this study were the seeds of four maize varieties. The imbibition pattern was obtained by weighing the seeds from 0 to 120 hours with a 6-hour time interval. The results showed that the four varieties showed a typical three-phase imbibition pattern with almost the same time. Overall, the highest seed growth and germination was found in Jantan F1 and Paramita, which have great potential for use in seed propagation, while Baruna variety showed low seed quality and needs further evaluation for improvement.

Abstract. Rosyad A, Ilyas S, Qadir A, Suhartanto MR, Sopandie D. 2025. Plant growth modeling in six landraces of Bambara groundnut seed production (Vigna subterranea). Biodiversitas 26: 2097-2105. The unavailability of high-quality seeds, low productivity, and lack of information on ecophysiological responses are the major problems in Bambara groundnut (Vigna subterranea) seed production. In this context, agro-climate components influencing plant growth include solar radiation and temperature. These components are quantified in the form of a plant model to influence growth through metabolic processes. A dynamic model is used as a solution to the problem. Therefore, this research aimed to create a dynamic model for the seed production of six Bambara groundnut landraces and to study the physiological processes related to yield. The stages in the model construction included (i) identifying system components, (ii) model construction, (iii) simulation, and (iv) validation. The ecophysiological reaction of plants to temperature and solar radiation in photosynthesis and respiration was constructed using the growth model. Model construction used the STELLA software.  Each landrace has different input components at each stage of development, including the carbohydrate partition coefficient, specific leaf area, extinction coefficient, and light usage efficiency. Simulated seed productivity on Tasikmalaya, Sukabumi, Sumedang, Small Sumedang, Bogor, and Gresik landrace was 2,115 kg ha-1, 2,263 kg ha-1, 1,975 kg ha-1, 1,890 kg ha-1, 2,179 kg ha-1, and 1,975 kg ha-1, respectively. The level of validity of the Tasikmalaya landrace, Sukabumi, Sumedang, Small Sumedang, Bogor, and Gresik growth model reached 82.4%, 82.4%, 94.1%, 82.4%, 88.2%, and 82.4%, respectively. These models are considered fit as the validity is greater than 80%. The seed production growth model with pod dry weight output was named 'The BAMSeed Model'. In practice, this model could benefit the researchers in predicting the yield of bambara groundnut using the selected system components.

Abstract

Melon (Cucumis melo L.) is a high-value horticultural commodity with an increasing market demand. This condition requires the availability of high-quality seeds to support optimal productivity and fruit quality. Therefore, a rapid, accurate, and non-destructive method for seed characterization is needed to support seed quality assesment. This study aimed to characterize Salfa F1 hybrid melon seeds using a digital imaging approach and to evaluate their morphophysiological characteristics  based on imbibition, germination, and vigor. The research was conducted at the Seed Biology and Reproduction Laboratory, Department of Agronomy and Horticulture, IPB University, from September to November 2025. The results showed that Salfa F1 melon seeds exhibited relatively homogeneous morphological characteristics based on  area, perimeter, and shape parameters (circularity, aspect ratio, and solidity). The imbibition pattern showed a nonlinier  response over time, with the qubic regression model providing a high level of fit to the observed data. In line with the imbibition pattern, the high germination percentage and vigor index indicated good physiological testing can provide complementary information for characterizing the morphophysiological quality of Salfa F1 melon seeds.

Abstract

Sweet corn is a high-value horticultural crop with steadily increasing demand for both fresh consumption and use as a raw material in the food industry. This study aims to evaluate the effectiveness of NPK 16-16-16 fertilizer on the growth and yield of sweet corn. The research was conducted at Sindangbarang Experimental Field, Faculty of Agriculture, IPB University from July to October 2025. This experiment used a Randomized Complete Block Design (RCBD) with a single factor, namely the dose of fertilizer application. Treatments were using fertilizer dosages of 0, 50, 0,75, 1,00, and 1,50 NPK 16-16-16, with a control treatment for comparison. During the vegetative phase, sweet corn exhibited similar growth responses across all fertilization levels relative to the control. However, all fertilizer doses significantly improved stover weight, cob weight with and without husk, cob length, cob diameter, yield per plot, and overall productivity compared to the control. The application of NPK 16-16-16 fertilizer at the recommended (1.0) rate achieved the highest relative agronomic effectiveness (103.11%), corresponding to a 1.03-fold yield increase over the control and outperforming the comparison treatment. Application of NPK 16-16-16 at the 1.0 recommended dose is suggested as the most efficient fertilization strategy for sweet corn production, as it maximizes yield and productivity without unnecessary increases in fertilizer input.

Abstract

Sweet corn (Zea mays var. saccharata) is a high-value horticultural crop whose productivity depends heavily on balanced fertilization. This study evaluated the effectiveness of a straight iron micronutrient fertilizer (Fe-EDTA, 12% Fe) applied together with varying rates of standard NPK on the growth and yield of sweet corn. The experiment was conducted at the IPB Sindangbarang Experimental Field, Bogor, from October 2025 to January 2026, using a Randomized Complete Block Design with a single factor and four replications. The six treatments were: control (P0); standard NPK (P1); and 0.25, 0.50, 0.75, and 1.00 NPK-std each combined with one foliar dose of Fe-EDTA (P2–P5), with the micronutrient applied three times at 4, 6, and 8 weeks after planting. During the vegetative phase, growth responses were broadly similar across the fertilized treatments. All fertilized treatments significantly increased stover weight, cob weight with and without husk, cob length, cob diameter, yield per plot, and productivity relative to the control. The highest productivity was recorded in P5 (13.16 t ha⁻¹) and P1 (13.12 t ha⁻¹), which did not differ significantly, indicating that adding Fe-EDTA to a full NPK rate did not further increase yield. Treatments combining Fe-EDTA with 0.50–0.75 NPK-std (P3–P4) produced yields statistically comparable to standard NPK (12.07–12.34 t ha⁻¹), and the highest Relative Agronomic Effectiveness was obtained in P5 (100.87%). These results suggest that, on soils with high native Fe availability, sweet corn yield is governed primarily by NPK supply, and that Fe-EDTA application combined with a reduced NPK rate can maintain productivity comparable to the full standard rate.
