Abstract

Soil properties play essential roles in transmitting and holding precipitation water; therefore, they determine the amount of plant-available water in the soil profile. The study aimed to compare the size distributions of Andept soil pores following four-year applications of vermicompost and liquid organic fertilizer (LOF). The experiment was done from 2016 to 2019. The five doses of vermicompost (5, 10, 15, 20, and 25 Mg ha-1) set as the main factor, supplemented with 0 and 100 percent concentrations of LOF as a sub-factor, were arranged in a split-plot design with three replicates. Results showed that adding LOF decreased slow-drainage pores significantly when combined with 10 Mg ha-1 of vermicompost. However, the pore changes by LOF were not significant when applied to other doses of vermicompost. Applying vermicompost and LOF lowered the slow-drainage pores by increasing soil organic carbon and reducing soil particle density. The findings suggest that vermicompost and LOF act as soil ameliorants to reduce water loss by drainage from soil profiles. The study highlights the importance of soil properties in determining plant-available water in the soil profile.

Abstract

The comprehensive evaluation of sweet corn hybrids developed for organic production n needs to be conducted across different environmental conditions prior to their adoption by farmers. This study aimed to assess and compare the growth and yield of 17 sweet corn hybrids grown organically in a midland region characterized by a monsoon rainfall pattern. It was conducted during the dry season from July to October 2024 in Sumber Pakis Village, Pakis District, Malang Regency, East Java Province at an altitude of 550 m above sea level. The experiment was designed in a randomized complete block design with three replications and involved 17 sweet corn hybrids as the treatments. Data were collected for the plant growth performance and the ear yield characteristics. In general, the findings of the study suggest that the dry season that took place throughout the growing period led to drought stress, which negatively impacted the performances of sweet corn plants, including growth and ear yield characteristics of most of the hybrids evaluated. The exception was Caps 22 × Caps 23, which had the ability to maintain normal growth performance. Likewise, only Caps 2 × Caps 5, Caps 5 × Caps 17B, Caps 17B × Caps 23, Caps 22 × Caps 23, and Paragon still produced notable marketable ears.

Abstract

The development of organic sweet corn varieties is ideally addressed to have a good adaptation to a variety of environmental conditions. This study aims to evaluate the performance of 17 sweet corn hybrids, consisting of 15 promising hybrids and 2 commercial hybrids grown organically in the highlands. The study was conducted in Batu City, East Java (1160 m above sea level) and arranged in a completely randomized block design with three replications. Evaluation was carried out on growth performance, productivity, and yield quality. The findings of the study showed that all tested hybrids exhibited good growth performance, as indicated by robust plant and a lot of leave. Nevertheless, Caps 2 x Caps 22, Caps 5 x Caps 17B, Caps 17B x Caps 23, and Caps 22 x Caps 23, respectively, emerged as the best hybrids in terms of overall growth performance. In terms of the productivity and quality of the ears produced, the hybrids Caps 5 x Caps 17B, Caps 5 x Caps 22, Caps 15 x Caps 17A, Caps 17A x Caps 17B, and Caps 17B x Caps 22 demonstrated their superiority in ear yields while meeting all established market quality standards.These findings suggest that, for orgnic production, these five hybrids can serve as the alternative for commercial varieties adressed for conventional production.  Further evaluation on the yield stability across environmental conditions is needed to  make these hybrids more predictable and dependable for the organic growers.

Abstract

Keunggulan Pupuk Organik Cair (POC) dibandingkan pupuk sintetik adalah memiliki efek residu yang lebih kecil bagi lingkungan. Disamping itu, selain kontribusinya dalam menyediakan unsur hara, POC dapat dibuat dari berbagai sumber bahan organik. Gulma atau tanaman pengganggu yang keberadaannya tidak diinginkan dapat dimanfaatkan sebagai sumber POC. Penelitian ini bertujuan untuk menentukan kosentrasi dan jenis POC terbaik terhadap pertumbuhan dan hasil tanaman bawang merah. Penelitian dilaksanakan di Kebun Percobaan Fakultas Pertanian, Universitas Bengkulu. Rancangan yang digunakan adalah Rancangan Acak Lengkap pola faktorial yang terdiri atas dua faktor perlakuan dan diulang tiga kali. Faktor pertama adalah Jenis POC, yaitu POC yang berasal dari gulma paitan (Tithonia diversifolia), babandotan (Ageratum conyzoides) dan eceng gondok (Eichhornia crassipes) sedangkan faktor kedua adalah konsentrasi POC terdiri atas 0%, 25%, 50%, 75% dan 100%. Variabel yang diamati meliputi tinggi tanaman, jumlah daun per rumpun, tingkat kehijauan daun, bobot brangkasan kering bagian atas, jumlah umbi per tanaman, dan bobot segar umbi per tanaman. POC berbahan dasar gulma paitan, gulma babandotan, dan eceng gondok memiliki dampak yang sama terhadap pertumbuhan dan hasil tanaman bawang merah. Oleh karena itu, ketiga gulma tersebut memiliki potensi sebagai POC untuk diaplikasikan pada tanaman bawang merah.Kata kunci: babandotan, bawang merah, eceng gondok, gulma paitan, POC.

Abstract

This study evaluated the physicochemical characteristics of degraded Inceptisol and the growth performance of Barangan banana (Musa paradisiaca L.) under two soil management systems—tillage and no-till—in Seluma, Bengkulu Province, Indonesia. Field observations were conducted on a 25 ha banana plantation, with soil samples collected at depths of 0–15 cm and 15–30 cm. Plant growth measurements were taken from two representative plants per plot. Data were analyzed using a randomized complete block design (RCBD), followed by Duncan’s Multiple Range Test (DMRT) at α = 0.05. Tillage significantly improved several soil properties, including bulk density, aggregate stability, and nutrient availability. Tilled plots exhibited greater aggregate stability, higher cation exchange capacity (CEC), and increased exchangeable K and available P. The surface layer (0–15 cm) also contained higher total nitrogen and available nutrients compared with deeper soil. For plant responses, tillage enhanced plant height and pseudostem girth, suggesting better soil structure and nutrient uptake, whereas no-till plots produced more leaves. Overall, moderate tillage improved soil physical quality and nutrient dynamics in degraded Inceptisol, thereby supporting superior vegetative growth of Barangan banana. Full text pdf

Abstract

Rice (Oryza sativa L.) is a major staple food crop in Indonesia whose production is highly vulnerable to flooding stress as a result of climate change. This article presents a systematic–narrative literature review examining scientific publications from the past ten years concerning the morphological and physiological responses of rice plants to flooding stress. The synthesis indicates that the main adaptive mechanisms of rice include the formation of aerenchyma tissue and adventitious roots, regulation of stem elongation (escape and quiescence strategies), and activation of anaerobic metabolism regulated by the SUB1A and SNORKEL1/2 genes. These mechanisms have been reported to enhance plant survival and maintain rice yield by approximately 20–40% compared with flood-intolerant varieties. An integrated understanding of these adaptive responses has important implications for the breeding of flood-tolerant rice varieties, adaptive water management in paddy fields, and the development of cultivation strategies in flood-prone areas to maintain rice production stability and support national food security amid climate change.

Abstract

Red chili pepper (Capsicum annuum L.) is a major horticultural crop with high economic importance and a vital role in meeting food demands. Its demand continues to increase alongside population growth, yet production is often limited by drought stress, particularly in coastal regions characterized by sandy soils, low water-holding capacity, and high salinity. This review aims to assess the physiological responses of red chili plants to drought stress in coastal environments and to identify adaptive mechanisms that enhance plant tolerance. Drought stress has been reported to decrease photosynthetic activity, chlorophyll concentration, and transpiration rate due to stomatal closure. Plants counteract water deficit by accumulating osmolytes such as proline and soluble sugars and by enhancing antioxidant enzyme activities, including superoxide dismutase (SOD) and peroxidase (POD), to mitigate oxidative damage. Drought conditions also result in significant reductions in plant height, flower number, and fruit yield, reaching up to 51%. These adaptive mechanisms highlight the importance of developing drought-tolerant cultivars and applying water-efficient cultivation techniques, such as silver-black plastic mulch and drip irrigation, to sustain red chili productivity in drought-prone coastal regions.
