Abstract

The exploration of arbuscular mycorrhiza fungi from sugarcane plantation in marginal land in South Sulawesi was carried out to find the source of inoculums showing effective infection. Soil samples were taken from four area with different characteristic of marginal land, namely land with low organic matter content, clay texture, limited irrigation, and undulating land. Mycorrhizae contained in the soil samples were then observed, and the spores obtained were used as the source of isolation by a single spore culture. The mycorrhizal spores were isolated by wet sieving and centrifugation method with 48% sucrose, which were observed under a compound microscope for spore details (100-1000x). Sugarcane root samples were taken to observe mycorrhizal infection in sugarcane root tissue by root staining method. The results of the study showed that the greatest diversity of mycorrhizal genera was found in soil samples of Jambua Block (Glomus, Gigaspora, and Sclerocistis) and AJ-5 Block area (Glomus, Acaulospora, and Sclerocistis). Single-spore isolates obtained were Glomus sp. and Acaulospora sp. Infection test result on four sugarcane varieties commonly grown in Takalar Sugar Factory showed that infectivity of mycorrhizal isolate of Acaulospora sp. was the highest (75%) and significantly different (LSD’test, p 0,05) compared to that of Glomus sp. (66%).

Abstract

One component of integrated rat management in rice fields is barn owl as biological control. The study was conducted to evaluate the occupancy rate of barn owl nest boxes, the local rat population, and rat damage to rice crops. It was conducted in three locations in Yogyakarta by observing 10 nest boxes per site. Assessment of their occupancy was monitored by barn owl presence in nest box (egg, chick, and adult) and natural nests in villages nearby. In comparison with control village, the local rat population was observed by the active burrow count method and linear trap barrier systems. Rat damage intensity is estimated by sampling 150 tillers using a stratified sampling approach. The result indicated that 1-4 nest boxes were occupied per location. The owls also nested within buildings nearby. Active burrows ranged from 4 to 25 burrows per 150 m. The rat damage area ranged from 33.33% - 48.57% with 6.33% - 14.86% damage intensity was significantly lower than the control site. Artificial nest box installation for owls in rice fields were only occupied for breeding. The use of barn owls for biological control of rice field rats should be combined with other methods in an integrated approach.

Abstract

The high demand for soybeans cannot yet be met by domestic production. Thus, a way to increase soybean production is necessary, one of which is to use liquid organic fertilizer derived from landfill leachate. This study aimed to examine the application method of liquid organic fertilizer (LOF) from landfill leachate to the soil and leaves and to determine the concentration giving the best growth and yield of soybean plants. The study was a field-research arranged in a completely randomized design (CRD) consisting of six treatments and four replications, which was carried out in a greenhouse. The treatments include A (0 LOF/L water), B (20 ml LOF/L water), C (30 ml LOF/L water, D (40 ml LOF/L water), E (50 ml LOF/L water) and F (60 ml LOF/L water). The liquid organic fertilizer was applied through the soil and leaves at a dose according to the treatments.  The results showed that the application of liquid organic fertilizer from landfill leachate was better applied to the soil than to the leaves. The liquid organic fertilizer given had a significant effect on the leaf area (cm2), crop weight (g), and plant seed weight (g), but not on the plant height (cm) and stem diameter (cm). Liquid organic fertilizer application is better given to the soil than to the leaves based on the independent T test. The liquid organic fertilizer from landfill leachate at a concentration of 40 ml/L of water had the best effect on the growth and yield of soybean plants.

Abstract

Intercropping soybean with corn on dry land with dry climate (DLDC) is an alternative program to expand the soybean cultivation harvested area. This study evaluated the effectiveness of fertilization performance in the intercropping of soybean-corn in DLDC. The experiment in this study was arranged in a randomized block design, consisting of seven fertilizer package treatments with four replications. The spacing between corn (Pertiwi 3) and soybean (Dena 1) was (50 cm x 200 cm) x 40 cm (2 plants/clump) and between soybeans (Dena 1) was 40 cm x 15 cm (2-3 plants/clumps). The observations consisted of soil analysis (pH, organic matter, total N (Kjeldahl), available P, Ca-dd, Mg-dd, K-dd, and Na-dd), soybean leaf chlorophyll index (45 and 60 days after planting/dap), plant height at (45 daps and harvest), number and weight of root nodules (45 daps); Corn: chlorophyll index (56 daps), plant height (harvest), analysis of corn and soybean plant tissue (60 daps), yield, and yield components of dry seeds of soybean and corn per hectare. The results showed that effective fertilization for the intercropped crops was 53 kg N + 1,500 kg of manure per hectare in corn plant and 7 kg N + 22 kg P2O5 + 18 kg K2O + 1,500 kg/ha manure + Rhizobium Iletrisoy/Agrisoy in soybean crops.

Abstract

Organic fertilizer can yield higher production compared to regular fertilizer if properly applied. Thus, it can be a solution to improve nutrient content of soil. The biggest source of bio slurry in plantation is from Palm Oil Mill Effluent (POME) and cow dung biogas. This research aimed to analyze the residue’s potential from the result of biogas processing and bio slurry from POME as slow-release fertilizer pellet. Bio slurry was processed into pellet through densification process using pellet mill. The research was arranged in a Randomized Block Design method with five slurry compositions as treatments, including 70:30, 60:40, 50:50, 40:60, and 30:70 (ratio of biogas slurry and POME slurry), each consisted of three replications. According to the data obtained, fertilizer pellets had characteristics of 25 – 29 mm of length, 5.23 – 5.85 mm of diameter, 0.44 – 0.53 g/cm3 of density, 54.78% - 81.96% of durability, and 7.81% - 8.57% of moisture content. Based on density and durability aspects, 30:70 composition was the higher. Macronutrient content of the five compositions were 1.88% - 2.72%, in which on day 22, N, P, and K release was 0.36 – 1.01%, 73.51 – 97.48%, and 3.19 – 7.85%, respectively. Meanwhile, on day 17, the nutrition solution conductivity of all compositions had already reached 0.80 – 1 mS/cm.

Abstract

Clove oil has the potential to suppress the development of the mosaic virus in patchouli plants, but its effectiveness in the field has not been studied. This study aimed to evaluate the effect of clove nano biopesticide on controlling patchouli mosaic disease. The research was conducted at the Manoko Experimental Garden, Bandung, West Java from March to November 2018. The patchouli used was Patchoulina-2 variety, which originated from the Seed Breeder Garden in Lembang, Bandung.  This study was arranged in a Randomized Block Design (RBD), consisting of five treatments and ten replications within each treatment, with one hundred plants in each replication. The results obtained showed that nano biopesticides of citronella, clove, and commercial citronella (Asimbo) were able to reduce the incidence and intensity of mosaic diseases in patchouli plants, showing the efficacy levels of 14.68%, 9.06%, and 5.83%, respectively. The application of citronella and clove biopesticides on Patchoulina-2 every month could increase plant fresh weight, when compared to the plants without treatment. Patchoulina-2 plants treated with nano biopesticides of clove and commercial citronella (Asimbo) showed higher value of fresh weight compared to those treated with citronella nano biopesticide. The clove nano biopesticide can also be developed to control mosaic diseases in patchouli plants.

Abstract

Humic substances (humus), allophanes and humus complexes are the soil component which have highly reactivity and give great contribution   on genesis and lead to presence  of specific chemical and physical properties of Andisols.  The study on humus, allophanes and humus complexes was conducted on Andisols in Tawangmangu Karanganyar District of Central Java and Bedugul, Tabanan District of Bali to observe the distribution of humus,  allophanes and humus complexes along the profile and the factor affected  its distribution. The result  showed  that the content of humus  complexes tend to decrease with the dept in accordance to the content of humus, on the contrary of the content of allophanes.  So the humus complexes are abundance on the upper layer whereas the allophanes on the lower layers of the profiles. By means of the regression calculation indicated  that both of the pH (H2O) of the soil and the content of humus are controlled the formation of humus complexes and I or allophanes along the profiles.
