2023-12-222023-12-228310.22146/ipas.92228Effects of seed soaking with plant growth regulators combination on the aggregation ability of shallot from seeds
https://jurnal.ugm.ac.id/jip/article/view/90993
<p>The true seed of shallot (TSS) is an alternative technology to boost high-quality seeds, farming cost efficiency, and shallot productivity in Indonesia. Despite the advantages of TSS, including extended shelf life and lower seed requirements, farmer and consumer acceptance remains limited due to the genetic and physiological constraints leading to single and large-sized bulbs, as an effect of low aggregation ability. This caused shallot bulbs from TSS to have a low price and were not suitable for use as seed bulbs. This research addresses challenges in shallot (<em>Allium cepa</em> L. Aggregatum group) production from TSS by investigating the impact of various plant growth regulators (PGRs) treatments and different soaking time on shallot growth and aggregation ability of 'Tuk Tuk' planting from TSS. The study in Yogyakarta employed a split-plot randomized block design from July to November 2018. The main plot varied the PGRs combination (9 treatment), while the subplot used the soaking time of 4 hours and 12 hours. The results indicated that a GA₃ concentration of 100 ppm, in synergy with NAA at 50 ppm for 12 hours, effectively enhanced aggregation compared to another treatment. Notably, the 'Tuk Tuk' shallot, characterized by low aggregation ability, demonstrated improved potential through seed treatment by PGRs, which could raise the number of bulbs from one to an average of two bulbs per plant. This study enhanced shallot aggregation ability, providing valuable insights for research and developing shallot production from true seeds in Indonesia.</p>Retno PangestutiEndang SulistyaningsihBudiastuti KurniasihRudi Hari Murti

https://jurnal.ugm.ac.id/jip/article/view/77785
The high phosphate retention in Andisols causes the availability of P to be low, can not be absorbed by plants. Actinomycetes are capable of solubilizing bound phosphates. This research aimed to identify Actinomycetes in Andisols Namanteran, assess their ability to increase phosphate availability, and understand how they work to increase phosphate availability in this soil. The research design used a factorial randomized block design with 2 factors; factor 1 was Actinomycetes isolate, consisting of A₀ = No Inoculant, A₁ = Inoculant A₁₃₂ (vegetable crops; 32 × 10⁸ CFU mL⁻¹), A₂ = A₄₆₈ (forest plants; 41 × 10⁸ CFU mL⁻¹), A₃ = A₄₅₈ (forest plant; 58 × 10⁸ CFUmL⁻¹), A₄ = A₄₇₁ (coffee plant; 35 × 10⁸ CFU mL⁻¹), A₅ = A₄₅₉ (forest plant; 63 × 10⁸ CFU mL⁻¹), A₆ = A₃₂₁ (hibiscus plant; 37 × 10⁸ CFU mL⁻¹), and A₇ = A₃₅₆ (vegetable plant; 33 × 10⁸ CFU mL⁻¹), and factor 2 was soil water content, consisting of K₁ = 50%, K₂ = 75% and K₃ = 100% of field capacity. The results showed that the availability of P in Andisols increased due to the application of Actinomycetes from 42.46 ppm to 159.20−266.60 ppm. The population of Actinomycetes in Actinomycetes treatment ranged from 27.33−31.58 × 10⁸ CFU mL⁻¹), with a soil pH of 4.41. Water content of 100% was the best in increasing soil pH and Actinomycetes population, but not having significant effects on the available P of the soil.

https://jurnal.ugm.ac.id/jip/article/view/88272
<p>In sustainable agricultural ecosystem management, a key focus is on minimizing chemical fertilizer use and maximizing the use of non-chemical alternatives. Our study was designed to explore the impact of mycorrhizal fungi and humic acid (HA) on the quantitative and qualitative characteristics of faba beans under varying chemical fertilizer levels. The experiment involved different treatments, which included HA and mycorrhiza in four variations (control, HA, HA+ mycorrhiza, and mycorrhiza alone), and nitrogen, phosphorus, and potassium (NPK) fertilizers at three different dosages (50%, 75%, and 100% of the recommended amount). The findings revealed that combining HA with mycorrhiza significantly influenced root colonization, with the highest chlorophyll a concentration (1.58 mg g⁻¹) observed in the HA+ mycorrhiza treatment at 75% NPK. This treatment also led to the highest counts in seeds per pod, number of pods, and weight of 100 seeds. Between the 100% and 75% NPK levels in the HA+ mycorrhiza treatment, no significant differences were noted in terms of grain and biological yield. The greatest grain yields were measured at 4356 kg ha⁻¹ and 4322 kg ha⁻¹ for the HA+ mycorrhiza treatment at 100% and 75% NPK, respectively. Additionally, the highest concentrations of Fe, N, P, K, and Zn were observed with the HA+ mycorrhiza application at the 100% NPK level.</p>Mandana MirbakhshSeyedeh Sara Sohrabi Sedeh

https://jurnal.ugm.ac.id/jip/article/view/84677
Drought condition is one of the major problems in producing rice in Indonesia. In plant breeding, selection is the main step to create superior varieties. An indicator of drought stress-tolerant rice varieties is the root distribution pattern because it describes the behavior of the roots in searching for water for photosynthesis and metabolism processes. One of the morphological traits related to drought tolerance in rice is root growth and development. This study aimed to determine the morphological and anatomical characteristics of drought-tolerant rice roots and identify drought-tolerant genotypes. The experiments were arranged in a factorial randomized block design with four replications. The first factor was genotype, consisting of ten genotypes. The second factor was drought stress, consisting of two environments without drought and with drought stress. Drought was given only in the vegetative phase, i.e., 1–14 days after planting. WINDEX analysis was performed to determine rice drought tolerance and identify drought-tolerant genotypes. The results showed that three out of the ten tested genotypes had higher WINDEX values, namely BP30411f (7.62), B13983-KA-6-3 (7.99), and BP29790d-PWK-2-SKI-1-3 (9.25). Based on the root distribution pattern, plants with longer primary root lengths, more seminal roots, longer seminal root lengths, and high root angles were predicted to be drought tolerant characteristics. Selection of these characters could be used in future rice breeding programs to obtain plants with superior genotypes.Adin NovitasariIndrastuti Apri RumantiRina Hapsari WeningDamanhuri Damanhuri

https://jurnal.ugm.ac.id/jip/article/view/80771
<p>Research on the effects of seed size, soil-based and soilless media to determine the best condition for increased seedling production of African walnut was carried out at the green house of Department of Crop Science and Technology, Federal University of Technology, Owerri. Seed size was categorized into 10.23 to 10.31g (for large seeds) and below 10.23g (for small seeds). Soil-based nursery medium was sawdust mixed with topsoil volume by volume (v/v) 1:1, while soilless was sawdust alone. The experiment was a 2×3 factorial in a complete randomized design with 6 replications. Data were collected on number of days to emergence, plant height at 4, 8, and 12 weeks after planting (WAP), and number of leaves at 4, 8, and 12 WAP. Data collected were tested with analysis of variance (ANOVA), and treatment means were separated with Fishers least significant difference at 5% level of probability. Result showed that large seeds planted on soil-based media performed best in all the assessed traits. The inference is that high quality seedlings of African walnut can be produced by planting large seeds in soil-based media.</p>Nwakuche Chinenye OnwubikoRaymond Onyedikachi Enwereji
