Abstract

The growth of mustard plants is influenced by the availability of nutrients through the application of fertilizers. Manure and sea mud are one type of biological fertilizer. The study aims to determine the optimal dose of sea mud and manure for the growth and production of mustard plants. The study design was a randomized group design consisting of 2 factors and repeated 3 times. The first of Sea Mud treatment (L) consists of levels, namely: L0 = Control; L1=500 g, L2= 750 g. L3 1000 g. The second factor is that the dose of manure consists of levels, namely: P0=without manure; P1=120 g, P2=160 g: and P3 = 200g. The results showed that L3 treatment was able to increase plant height, while the number of leaves was best in L2 treatment. This treatment was also able to increase the number of leaves, fresh weight and dry weight but between L2 and L3 treatments did not differ markedly. P3 manure treatment is able to increase the best number of leaves, while fresh weight is best P2 treatment. The interaction between treatments only occurred in plant height and leaf area parameters at 17 HST observations.

Abstract

Mung bean is a supplemental and alternative food source whose disease attacks often hamper cultivation. One of the main diseases that attacks mung beans is wet root rot caused by R. solani, which has a negative effect on growth and causes a decrease in crop yield. This research aimed to determine mung bean lines resistant to wet root rot disease and the level of resistance of the lines from the Tanimbar Islands to wet root rot disease. This research was carried out at the Disease Diagnosis Laboratory, Pattimura University, and took place from July to September 2023. It used descriptive analysis involving eight treatments in the form of 8 local mung bean genotypes from the Tanimbar Islands. The R. solani isolate used to test the resistance of mung bean genotypes was taken from samples of diseased plants (mustard), isolated on PDA media, and grown for seven days. The genotypes that were tested by inoculation at the seedling stage consisted of KC_3-8, KC_6-1, KC_8-2, KC_9-10, KC_23-6, KC_23-8, KC_23-9, and KC_26-4. In addition to the growth of young seedlings after inoculation, the parameters as indicators of mung bean resistance were the incubation period and disease severity in each genotype. Analyses of the incubation period, severity of wet root rot disease, and vegetative plant growth data consisting of sprout height, number of leaves, root length, and fresh and dry weight, were carried out descriptively. The results of this study indicate that three genotypes were moderately susceptible to R. solani, namely KC_6-1, KC_3-8, and KC_9-10; whereas the genotypes KC_26-4, KC_23-6, KC_25-8, KC_25-8, KC_28-9 were included in the susceptible category. The lowest root rot disease severity was found in genotypes KC_6-1, KC_3-8, and KC_9-10, while the other five genotypes were in the high category.

Abstract

Waste derived from plant material can be used as a source of plant nutrients. These waste products can be processed into compost to increase soil organic matter. The study aimed to determine the effect of cocoa peel ash application on drought conditions and natural sources of potassium for the growth and production of maize plants. The research design is a Factorial experiment in a Completely Randomized Design consisting of two treatments, namely: the amount of water application equivalent to rainfall (R): (R1) 70 mm / month, (R2) 80 mm / month, and (R3) 90 mm / month; fertilization of cocoa skin ash (K): control (K0), 100 kg/ha (K1), 150 kg/ha (K2), 200 kg/ha (K3), and, (K4) 250 kg/ha repeated 3 times. The results showed that the interaction between cocoa bark ash fertilization and the amount of water application equivalent to rainfall had a very noticeable effect on plant height and leaf area variables, while stem diameter changes had a noticeable effect. Fertilization treatment of 250 kg/ha (K4) best affects plant height, stem diameter, leaf area, and dry weight. The dose of cocoa husk ash fertilization of 200 kg/ha gives the best results on the weight of the seeds per plant, while the dose of 150 kg/ha is best at the weight of 100 seeds. Treatment of the amount of water application equivalent to rainfall of 90 mm/month gives the best results on leaf area, seed weight per plant, weight of 100 seeds, dry weight of plants, and harvest index

Abstract

The sago plant is a staple food for the people of Maluku and Papua and has many benefits and advantages to continue to be developed. A group of phylloplane microbes grow and spread on the surface of the leaves. The objective study is to find isolates of phylloplane bacteria from sago accession Makanaru and determine the inhibition of these bacteria against the growth of Rhizoctonia solani Kuhn. Sampling of sago plants (upper, middle, and lower leaves) was conducted in Negeri Seith, Leihitu District, Central Maluku Regency. Based on the isolation results, 21 isolates of phylloplanes bacteria were obtained and ready for further testing. From the results of hypersensitive test selection, 14 non-pathogenic isolates of phylloplane bacteria were obtained. Furthermore, tested the inhibitory power of phylloplane bacteria in suppressing the growth of the fungus, 3 phylloplane bacteria isolates were obtained with strong inhibitory, namely DA3.3, DT3.2, DT3.1 followed by 3 isolates DB4, DB4.2, and DB4.4 (medium inhibitory) which have the potential to be developed as biological agents.

Abstract

This research aims to analyze the potential of essential compounds of Cinnamonum burmannii and Cinnamonum cullilawan as a bioagent for Fusarium oxysporum and to test the efficacy of both essential oils in controlling the growth of the fungus F. oxysporum. Oil extraction was carried out using the steam-water distillation method, and analysis of the components of the oil compounds of the cinnamon was carried out using the GC-MS method. Essential oils were tested for their efficacy for inhibiting F. oxysporum with four concentrations, namely 0.06%, 0.125%, 0.25%, and 0.5% on PDA and PDB media. The results show that the main essential compound in C. burmannii is cinnamaldehyde at 20.61%, and in C. cullilawan, it is eugenol at 26.33%. The essential compounds of both have antifungal activity against F. oxysporum, with a concentration rate of 0.125% being able to inhibit the growth of F. oxysporum. The main active compounds, such as cinnamaldehyde and eugenol, play an important role in the fungus control mechanism. This research concludes that the essential compounds from both have the potential to inhibit F. oxysporum growth.

Abstract

Xanthomonas oryzae pv.oryzae merupakan salah satu bakteri patogen yang menyerang tanaman padi. Pengendalian terhadap penyakit ini telah banyak dilakukan dan salah satu teknik pengendalian yang dikembangkan saat ini melalui teknologi induksi ketahanan tanaman yang mengekspresikan gen PR-1. Penelitian kami untuk mendeskripsikan ekspresi gen PR-1 pada varietas padi IR64 yang terinduksi resistensinya oleh asosiasi antara bakteri endofit dan asam salisilat. Gen PR-1 dianalisis secara molekuler dan ekspresinya menunjukkan tanaman padi yang terinduksi resistensinya secara tunggal maupun kombinasi oleh kedua agens ini mem­perlihatkan adanya ekspresi protein PR-1. Ekspresi protein ini dipicu oleh aktivitas kedua agens penginduksi yang bekerja secara simultan untuk membentuk protein yang mampu menekan perkembangan penyakit ini. PR-1 bekerja sesuai dengan mekanisme dari masing-masing agens penginduksi resistensi tanaman. Varietas IR64 yang diketahui rentan terhadap penyakit hawar daun bakteri terbukti dapat ditingkatkan ketahanannya menjadi moderat.  Pemanfaatan induksi ketahanan tanaman melalui aktivitas kedua agens pengimbas yang membentuk protein PR-1 perlu dilanjutkan dengan inovasi formulasi teknik pengendalian yang diberikan secara simultan sebagai alternatif strategi pengendalian hawar daun bakteri maupun penyakit lainnya ke depan dengan pendekatan ramah lingkungan dan berkelanjutan.
