Abstract

Keberadaan anggrek D. bicaudatum mulai mengkhawatirkan. Kerusakan alam akibat aktivitas manusia dan pengambilan anggrek di alam secara berlebih memicu kepunahan anggrek pada habitat asal. Tindakan konservasi tanaman baik secara in situ maupun ex situ perlu dilakukan untuk mengurangi ancaman kepunahan anggrek tersebut. Penelitin bertujuan untuk menyelidiki efek dari paclobutrazol pada media kultur sebagai penghambat pertumbuhan tanaman, salah satu upaya konservasi secara in vitro. Penelitian dilakukan secara eksperimental menggunakan rancangan acak lengkap. Variabel bebas penelitian adalah konsentrasi PBZ berturut-turut 0, 1, 3, dan 5 mg L-1 yang ditambahkan pada medium tanam berupa MS padat. Hasil penelitian menunjukkan konservasi jangka menengah anggrek D. bicaudatum dengan penambahan pactobutrazol menunjukkan pengaruh yang sangat nyata. Penghambatan pertumbuhan vegetatif seperti jumlah daun dan panjang akar terdapat pada PBZ 1-5 mg L-1, sedangkan pada variabel diameter batang terjadi pembesaran pada semua perlakuan dibandingkan kontrol. Reduksi jumlah akar terjadi pada perlakuan PBZ 1 dan 3 mg L-1. Kata kunci: kepunahan, kultur in Vitro, reduksi

Abstract

The palm breeding and cultivation challenges are mainly related to the seed germination process. Various factors, including seed dormancy, often influence this process. Various scarification methods and several types of palms that can play a role in breaking dormancy need to be tried. This research aims to determine the best dormancy-breaking scarification method for various palm seeds. This research was carried out in Bakung Village, Sukasada District, Buleleng Regency, from January to March 2024, using a Nested Design comprising two factors. The first factor is that the type of palm seed consists of four levels: Putri palm, Pinang palm, Squirrel Tail palm, and Green palm. The second factor consists of six levels, namely control method (without peeling), peel scarification method, peel scarification method+warm water, peel scarification method+H2SO4, peel scarification method+KNO3, peel scarification method+GA3. The results of the research showed that the scarification method had a significant effect (p<0,05) on the percentage of sprouts and shoot length. Very significant effect (p<0,01) on the variables of germination, maximum growth potential, seed growth speed, and root length, had an not significant effect on the synchronization of seed growth. This research concludes that the scarification method affects breaking seed dormancy in several types of palm, except for the areca palm.

Abstract

Choosing the right seed size is essential in shallot cultivation. Using good-quality seeds will increase the growth of shallots. Through growth analysis of various sizes of shallot seedlings, information will be obtained about the growth potential of shallots. This research aims to compare the growth patterns of shallot seedlings of varying sizes. The research was carried out from August to September 2023 at Br. Aseman, Sedang Village, Abiansemal District, Badung Regency, Bali and at the Plant Breeding and Seed Technology Laboratory, Faculty of Agriculture, Udayana University, Denpasar. This research used a one-factor randomized block design (RBD) with different treatment sizes of shallot seedlings, namely 3 g, 5 g, 7 g, 9 g, and 11 g. Each treatment was repeated 5 times, yielding 25 experimental units. The results showed that differences in the size of shallot seedlings very significantly influenced the initial growth of the seedlings (3-15 DAP). The heavier the weight of the shallot seeds, the higher the growth of the shallots. The plant growth analysis metrics, relative growth rate and net assimilation rate, reveal that the results do not differ significantly across observation time intervals. The treatment using seed size 11 g showed the highest increase in each parameter compared to other treatments at each observation time interval.

Abstract

Farmers have applied fertilization but have not achieved optimal vegetative growth of Tejakula tangerine plants. This study aims to find a combination of fertilization packages that can provide the best response to vegetative growth and improve the soil quality of Tejakula tangerine plants after moving to the field. The research was conducted in Tembok Village, Tejakula District, Buleleng Regency, Bali from  July to December 2023. The experiment used a one-factor Randomized Block Design (RBD) with fertilization package treatment consisting of 3 levels, namely: 5 kg cow manure per tree, 5 kg cow manure + mycorrhizal biofertilizer 20 spores/50 g volcanic sand carrier + probiotic liquid organic fertilizer 20% concentration per tree and 5 kg cow manure + urea 50 g + SP-36 25 g + KCl 20 g per tree. Each treatment was repeated 8 times, resulting in 24 experimental units. Observational data were analyzed using the Analysis of Variance (ANOVA) test, and further tests were carried out using the Least Significant Difference (LSD) test. The results showed that the fertilizer package treatment had a very significant effect on the variable number of primary branches and leaf P nutrient content, significantly affected the variable number of plant stem diameter and leaf chlorophyll content, but had no significant effect on the variable number of plant height, relative water content (RWC) of leaves and leaf color. The package of cow manure + inorganic fertilizer influenced the vegetative growth of Tejakula tangerine after transplanting to the field very significantly on the increase in primary branches, significantly influenced the increase in plant stem diameter and leaf chlorophyll content. The organic fertilization package + mycorrhizal biofertilizer + probiotic liquid organic fertilizer can improve the soil quality of Tejakula tangerine plants.

Abstract

Market demand for baby romaine lettuce (Lactuca sativa L. var. longifolia) continues to rise alongside the public’s growing preference for healthy lifestyles, yet its productivity still needs improvement. This study aims to evaluate the effect of seedling density per planting hole on the growth and yield of baby romaine lettuce using the Deep Flow Technique (DFT) hydroponic system and to determine the optimal number of seedlings. The experiment was conducted in a greenhouse in Pelaga Village, Bali, using a completely randomized design (CRD) with a single factor comprising five seedling densities (1, 2, 3, 4, and 5 seedlings per hole) and six replications, totaling 120 plants.  Growth and yield parameters were analyzed using ANOVA and LSD at a 5% significance level, with regression applied to fresh shoot and crop weight. Results showed that increasing the number of seedlings significantly affected plant height, stem diameter, chlorophyll content, fresh and dry shoot weight, and total fresh biomass. Shoot fresh weight increased linearly (Y = 97.86 + 11.71X; R² = 0.975), while crop fresh weight followed a quadratic trend (Y = 70.64 + 8.10X – 1.00X²; R² = 0.863), with the optimal yield obtained at three seedlings per hole. It is concluded that planting three seedlings per hole offers the best outcome in terms of both quality and quantity in a DFT hydroponic system.

Abstract

Purpose: This research aims to analyze the effect of organic and inorganic fertilizer packages on the growth of Tejakula tangerine plants and changes in soil chemical properties after being given organic and inorganic fertilizer packages. Research methods: The method used in this research was a Randomized Block Design (RAK) with 1 (one) factor. The treatment tested was the fertilizer package dose (P), consisting of 3 levels, namely organic fertilizer/cow manure (Po), organic cow manure + 22.6 g Urea fertilizer + 4 g KCl fertilizer + Phonska Plus 15 fertilizer -15-15 dose 84 g (Ph), and organic cow manure fertilizer + Urea fertilizer dose 22.6 g, KCl fertilizer dose 4 g, Phonska Plus fertilizer 15-15-15 dose 84 g + mycorrhizal biofertilizer + liquid organic fertilizer (POC) probiotics (Pc). Each treatment was repeated 8 times to obtain 24 treatments. Findings: The response to the fertilizer package had a significant to very significant effect on plant growth, such as increasing plant height, increasing the number of primary branches, increasing stem diameter and number of leaves. The fertilizer package that gave the highest response to plant height, number of leaves, while the increase in stem diameter had the same effect. Primary branch augmentation is the most influential Ph package but is not significantly different from PC. The effect of fertilizer packages on changes in soil chemical properties is that pH is neutral, DHL is classified as low to very high, C-org is classified as high, N-tot is classified as medium, P-available and K-available is classified as very high. Implication: The effect of mixed organic, inorganic and biological fertilizers and probiotic POC provide the best response to plant growth and increase DHL in the soil.
