Abstract

Intercropping patterns in upland rice must be carefully managed to prevent excessive competition among crops. This research aimed to determine the ideal proportion of upland rice–legume intercropped and legume types for rice growth and yield. The research was conducted in Mersi, East Purwokerto, Banyumas, Central Java, from April–August 2025. The study was arranged in a split-plot design consisting of a main factor in form of the proportion of upland rice to legumes (1:1, 2:1, and 3:1), and a sub-factor, i.e., legume types (peanuts, mung beans, and soybeans). The data were analyzed using Analysis of Variance and Tukey's HSD test at α = 5%. The results showed that the height of upland rice plants in intercropping was significantly higher than in sole cropping at 35 and 56 days after planting (DAP). The SPAD leaf greenness index of upland rice leaves at 70 DAP in sole cropping was significantly higher than in intercropping. Intercropping produced the insignificant number of stems, leaves, panicles, dry weight, number, and weight of grain per plant as upland rice in sole cropping. The number and weight of empty grains per plant, as well as upland rice productivity in sole cropping, were significantly higher than in intercropping. Both factors did not significantly affect the growth and yield of upland rice under intercropping condition. Intercropping upland rice and peanuts at a 2:1 planting proportion resulted in a land equivalent ratio greater than 1, indicating that the system was productive and efficient despite a high competitive ratio.

Abstract

Glyphosate is a non-selective systemic herbicide that has been widely used to control weeds by local corn farmers in South Sulawesi and Lampung Provinces of Indonesia. However, some corn farmers in these two regions were considered that glyphosate herbicide at the standard field dose no longer effective against goosegrass (Eleusine indica). To confirms the level of its resistance to glyphosate, seeds of E. indica suspected to be glyphosate-resistant were collected from corn fields in Soppeng Regency-South Sulawesi and South Lampung Regency-Lampung (designated as GR-1 and GR-2 respectively), along with a known susceptible biotype from Sumedang Regency-West Java (GS) as a comparison. By using whole-plant pot assay method in a greenhouse at the Ciparanje. A range of seven glyphosate concentrations was applied to the seedlings at the Experimental Farm, representing 0, 0.25, 0.5, 1, 2, 4, and 8 x the standard field rate. Dose–response experiment showed that GR-1 and GR-2 biotypes has a low levels resistance to glyphosate (2.57 and 2.96 folds of each) compared to susceptible biotype (GS). Sequencing results confirmed the Pro-106-Ser mutation in the EPSPS genes of the resistant biotypes. This specific amino acid substitution is among the most frequently documented mechanisms of resistance in weed species. Therefore, the shared mutation in the GR-1 and GR-2 biotypes likely confers this resistance. These findings serve as an early warning for corn farmers to manage and prevent further spread of E. indica glyphosate-resistant biotypes.

Abstract

One strategy to increase shallot production is the utilization of microorganisms in the soil, such as arbuscular mycorrhizal fungi (AMF), which is applied together with fertilizer. This research aimed to investigate the effects of different nutrient inputs and mycorrhizal association on the growth and yield of shallots. This study used a split-plot design with three replications as blocks. The main plot included four treatments: no nutrient inputs, NPK fertilizer, NK fertilizer, and humic acid, while the subplot involved the mycorrhiza application (with or without). The measured variables included growth (plant height and number of leaves) and yield (fresh weight and number of bulbs per plant). The results showed no interaction between treatments for any growth or yield parameters. Application of humic acid significantly improved shallot development and yield, producing the highest results compared to other fertilizer types. Mycorrhizal inoculation enhanced plant height and boosted bulb weight per plant. The application of humic substances has been proven to increase 27.82%, while AMF enhanced 12.9 % weight bulb of shallots. Hence, humic substances have the potential to enhance the shallot with or without AMF application.

Abstract

Soybean production has been extended to saline areas. This development is a strategy to expand planting areas to suboptimal land to increase worldwide production. To support cultivation in these locations, it is necessary to develop superior varieties that are resistant to salinity and provide supporting technological inputs. In saline conditions, soybeans may face stress that leads to morphological, physiological, and yield disturbances. Consequently, the response of several soybeans in East Java should be observed. This study is a pot experiment and arranged in a Factorial Completely Randomized Design (CRD) consisting of two factors, soybean varieties and NaCl concentrations. The treatments comprise several NaCl levels: 0 g/L (non-saline), 5 g/L (moderate salinity), 15 g/L (high salinity), and 25 g/L (very high salinity). The observation used several parameters: chlorophyll content, plant height, leaf number, flowering time, pod forming time, number of pods, number of seeds, weight of 100 seeds, and harvest time. The soybean varieties used were Anjasmoro, Wilis, Dering 1, and Dering 3. Anjasmoro was identified as the soybean variety most tolerant to salinity stress based on chlorophyll content, morphology, and yield.

Abstract

The availability of phosphorus (P) is one of the main limiting factors for plant productivity in Andisol soils due to the strong fixation of P by allophane clay minerals, aluminum and iron oxides. Giving the phosphate solubilizing fungi (PSF) is an alternative to increase available P which plants can use to increase the yield. This study aimed to evaluate the effectiveness of phosphate-solubilizing fungi (PSF) in improving P availability on Andisol. The experiment used a block randomized design (BRD) with three replications. The first factor is Andisol soil origin (Soil 1 and Soil 2) and the second is isolate of phosphate solubilizing fungi (Aspergillus niger P13, A. niger P21, A. pseudodeflectus BJ21, and A. niger BJ23). The research results showed that Soil 1 generally produces higher growth and yield of shallots than soil 2. A. pseudodeflectus BJ21 can increase available P by 48.46% and A. niger P13 by 45.71% compared to without phosphate solubilizing fungi. A. niger P13 can reduce P retention by 18.48% compared to without phosphate solubilizing fungi. A. niger BJ23 can increase plant P uptake by 35.35% compared to without phosphate solubilizing fungi. Inoculation of isolates A. niger P13 and A. pseudodeflectus BJ21 was able to adapt and grow well on Andisol soil which significantly increased the population compared to the control. Indigenous phosphate-solubilizing fungi (A. niger and A. pseudodeflectus) improved P availability and uptake in Andisol, reduced P retention, adapted well to the soil environment, and showed strong potential as environmentally friendly biofertilizers based on local resources.
