Abstract

Setiyoningrum F, Pribadi G, Afiati F, Herlina N, Solikhin A, Lisani N. 2018. Functional properties of Saccharomyces kluyveri Y97-fermented solo black garlic. Asian J Agric 2: 48-51. Saccharomyces kluyveri Y97-fermented solo black garlic was made by fermentation of fresh solo garlic in medium containing S. kluyveri aging in 70C and relative humidity close to 60%. The fermentation period of fresh solo garlic in the medium was 0, 2, 4 dan 6 days. The black aging period was 0 (fresh garlic), 7, 14 dan 21 days. Antioxidant capacity, flavonoid content and total poliphenol were observed. S. kluyveri Y97-fermented solo black garlic had higher antioxidant capacity, flavonoid content and total polifenol compared to solo black garlic without fermentation. Fermentation of fresh solo garlic by S. kluyveri Y97 before aging process could increase solo black garlic’s functional properties.

Abstract. Olatidoye MS, Alimi T, Akinola AA. 2018. Quality assessment of the physico-chemical properties of vermiwash produced from different sources during successive storage periods. Asian J Agric 2: 58-63. The study investigated on socio-economic factors and estimated the technical efficiency indices and factors influencing technical efficiency of the sampled cotton farmers in the Southern Cotton growing zone of Nigeria. A multistage sampling technique was employed to select a total sample of 300 cotton farmers. The study made use of only primary data which was collected through the aid of a well-structured questionnaire. The data were analyzed using descriptive statistics and stochastic frontier production parametric model. The results of the descriptive statistics showed that majority (83%) of the cotton farmers in the study area were males while the mean age of the respondents was 49 years. The average household size was 8 persons per household and majority (69%) of the respondents had formal education. Majority of the respondents (59%) had no access to credit facilities while majority (80.4%) of the cotton farmers had reasonable years of experience ranging between 11 and above in cotton production. Furthermore, the study found that the technical efficiency of the farmers range from 0.35 and 0.99 with a mean of 0.79. This indicates ample opportunity for farmers to increase their productivity through improvement in their technical efficiency. Seed, fertilizer, pesticides and farm size were found to be statistically significant and positively related to farmers’ output while education, credit, extension contact and farming experience of the respondents negatively influenced farmers’ technical inefficiency. The farmers therefore need to increase their output through more intensive use of seed, land, pesticides and fertilizers.

Abstract. Safitri YA, Hasanah U, Salamiah, Samharinto, Pramudi MI. 2019. Distribution of major diseases of shallot in South Kalimantan, Indonesia. Asian J Agric 3: 33-40. Shallot is a vegetable crop with high economic value, but its productivity in Indonesia is still relatively low. One of the causes is due to attack of the diseases. The research was conducted from November 2017 to April 2018, with the purpose of studying the distribution of major diseases of shallots in South Kalimantan. It consisted of field, laboratory, and greenhouse research. Field research involved the survey of shallots’ extensive planting in eight villages of six districts in South Kalimantan, disease symptoms, the broad of attack, and the collection of secondary data. Laboratory research included the isolation and identification of the pathogen causing diseases. The greenhouse research was conducted to perform the Postulate Koch test. The research result showed that there were two major diseases of shallots, namely Moler and Anthracnose. Pathogen causing Moler disease (Fusarium oxysporum) attacked shallot plant in six districts (Tabalong, Balangan, Tanah Laut, Kotabaru, Tapin, and Banjarbaru) and pathogen causing Anthracnose disease (Colletotrichum sp) attacked shallot plant in five districts (Tabalong, Balangan, Tanah Laut, Kotabaru, and Tapin).

Abstract. Jaikishun S, Adonis S, Ansari AA. 2018. Quality assessment of the physicochemical properties of vermiwash produced from different sources during successive storage periods. Asian J Agric 2: 52-57. Organic farming is crucial for maintaining our health together with improving quality and quantity of crop production in environmentally friendly farming practices. Vermiwash is poised to be one of the key components in organic farming and reducing the enormous amounts of pollutants from the environment. This study aims to determine the physicochemical characteristics related to vermiwash from different sources (Jamun, Neem and Grass with combination and mixed with cattle dung) during a three-month storage period with monthly assessments and compared to fresh sample. While an increase in Electrical Conductivity (EC) was seen at the first month, successive decreases were noted thereafter with a significant difference (p=0.05) being observed among the treatments (p=0.05) after three months. Total dissolved salts decreased over the storage period with significant difference being observed among the treatments and storage period revealed that at p=0.05, F (7, 21) = 3.9>2.49 Fcrit. and F (3, 21) = 3.8>2.49 respectively. Phosphorous decreased while potassium increased with T7 having the highest. Calcium showed a significant difference (p=0.05) among the treatments while magnesium fluctuated during the period but deceased at the end of the storage period. Analysis of ferrous content revealed a significant difference (p=0.05, F (7, 21) = 3.8>2.48 Fcrit.) with the time period being significantly different (p=0.05, F (3, 21) = 6.8>3.0) with an increase at the end of the storage period. Fresh form of vermiwash is best to use to obtain maximum nutrients as the general nutrient composition deteriorates over with time

Abstract. Prihantini AI, Rizqiani K. 2019. Various antioxidant assays of agarwood extracts (Gyrinops versteegii) from West Lombok, West Nusa Tenggara, Indonesia. Asian J Agric 3: 1-5. However, the species have not been widely explored as a source of natural products in particular antioxidant agents, which protect cells from damage caused by free radicals. The present study was aimed to evaluate antioxidant activities of agarwood extracts from West Nusa Tenggara using various antioxidant assays. The antioxidant activity of leaf, fruit and fruit bark extracts were investigated based on DPPH radicals scavenging activity, reducing power, and β-carotene bleaching assays. The total phenolic content was also investigated. The result showed that leaf extract revealed the strongest antioxidant activity on all assays performed such as DPPH radicals scavenging activity (IC50 22.13±0.71 μg/mL); reducing power (251.85±0.03 mg QE/g dry extract); and β-carotene bleaching activity (IC50 24.23±2.60 μg/mL). The total phenolic content (TPC) in the leaf was higher (184.90±0.76 mg GAE/g dry extract) than fruit bark and bark extracts. The high content of phenolic compounds in G. versteegii leaves indicated that these compounds might contribute to the antioxidant activities. In conclusion, these findings showed that G. versteegii leaves are potential for development as an antioxidant source.

Abstract. Rahayu HSP, Muchtar, Saidah. 2019. The feasibility and farmer perception of true shallot seed technology in Sigi District, Central Sulawesi, Indonesia. Asian J Agric 3: 16-21. Shallot is one of horticultural commodities that plays a significant role in both national and regional economy. A fluctuating supply of shallot influences the inflation level. Shallot production is currently still facing many problems, including high production cost. The high shallot production cost mostly goes to expenses for labor and seed while Indonesian shallot is mainly produced from the bulbs seed. This high-cost production causes a lower shallot competitiveness. Therefore, introduction of True Shallot Seed (TSS) technology, which lowers the cost for shallot seed, could be an ideal option to improve the shallot competitiveness in Indonesia. However, the shallot farming feasibility and the farmer’s perception of this technology are two critical aspects that need to be considered in the adoption of this new technology. This research aimed to study the potency of true shallot seed development in Central Sulawesi based on the TSS’s farming feasibility and farmer perception on TSS. The research was conducted in Sigi District, Central Sulawesi. The results showed that the farming of shallot using TSS was feasible, and within 14.9 t.ha-1 productivity, the Revenue-Cost Ratio was 3.15 while the Benefit-Cost Ratio was 2.15. The perception was examined based on three aspects namely technical, economic, and social aspects. The results showed that farmers were interested in planting true seed of shallot based on its high productivity, lower production cost, and market acceptance of the product; while in the social aspect, the extension and farmer group’s support still need to be improved for development of TSS.

Abstract. Islam MDA, Rahman MDA, Hossain MK. 2019. Effect of container and potting media on raising quality seedlings of Acacia auriculiformis in the nursery. Asian J Agric 3: 26-32. The study elucidates the effect of container and potting media on raising quality seedlings of Acacia auriculiformis in the nursery of the Institute of Forestry and Environmental Sciences, University of Chittagong to find out a suitable container and potting media for raising large scale quality seedlings. The seedlings were evaluated by five container and seven potting media treatments for eight months. A Completely Randomized Block Design (CRBD) was adopted for the study with three replications for each treatment. The Analysis of variance (ANOVA) and Duncan’s Multiple Range Test (DMRT) was tested for the analysis to explore the possible treatment variations. However, the study reveals nodulation with growth parameters; shoot and root dry biomass production and quality index were highest in 20 cm × 15 cm size polybags whereas the highest root length and shoot-root ratio was observed in 15 cm × 10 cm and 15 cm × 13 cm size polybag respectively. Considering the potting media, highest nodulation, growth parameters, shoot dry and fresh weight, shoot- root ratio and biomass were found in combination of soil + cow dung + phosphorus (0.16 g/polybag). Highest root length, root fresh and dry weight, and quality index were found in the combination of soil + cow dung (3:1). Therefore, it is recommended that containers of 20 cm × 15 cm size polybag and with a potting media of soil + cow dung + phosphorus (3 parts soil, 1 parts cow dung + 0.16 g/polybag) combination produce quality A. auriculiformis seedlings in the nursery.

Ramnarain YI, Ori L, Ansari AA. 2017. Evaluation of the use of vermicompost on the crop production of two varieties of Pak choi (Brassica rapa var. chinensis) and on the soil structure in Suriname. Asian J Agric 1: 73-79. The present research was carried out from January to May 2016 at the Anton de Kom University of Suriname, Paramaribo. The investigation consisted of a field and laboratory study in order to evaluate the effect of vermicompost on crop production of 2 varieties Brassica rapa var. chinensis, white and green Pak choi, nutrient availability in the soil after the use of vermicompost and nutrient value of the crop.The experiment was carried out (completely randomized design) in a greenhouse for six weeks. The treatments were vermicompost (V), cow manure (S), chemical fertilizer (K) and control (C). Plant growth parameters were recorded during the experiment (plant height and number of leaves) and after harvest (root and shoot biomass, leaf area). Nutrient analysis (Ca and Fe) of Pak choi was also conducted followed by pre and post-experiment soil analysis (pH, EC, TOC, N, P, K and C/N ratio). The results were collected and analyzed using Sigma Plot 12.0 tools. In the white Pak choi the number of leaves, root length and weight of fresh plants showed no significant differences among the four treatments using Tukeyâ??s test (Pâ?¤0.05). In the green Pak choi the number of leaves and root length showed no significant differences among the four treatments by Tukeyâ??s test (Pâ?¤0.05). Furthermore, the soil parameters (pH, OC, N) did not indicate a significant increase or decrease of the elements in the soil. P did decrease significantly and K increase in the treatments in the soil was not relevant.The evaluation of the use of vermicompost on the crop production of 2 varieties of Pak choi (Brassica rapa var. chinensis) proved that the plants treated with vermicompost had similar results as those treated with cow manure and chemical fertilizer.

Abstract

Elidar Y. 2018. Seed emergence and growth of the short age sugar palm (Arenga pinnata) as a response of seed scarification and liquid organic fertilizer application. Asian J Agric 2: 8-13. The research was aimed to know the effect of seed scarification and liquid organic fertilizer application to the seed emergence and growth of the short age sugar palm (Arenga pinnata (Wurmb.) Merr). The research was conducted at two experiments, i.e. (i) effect of seed scarification, and (ii) effect of liquid organic fertilizer application. The first experiment was a single factor designed at Completely Randomized Design (CRD). The factor consisted of 4 scarification technique treatments i.e. s1 = seed abaxial scarification; s1 = seed tip scarification; s3 = seed left and right sides scarification; s4= seed embryo scarification. All treatments were replicated 6 times. The second experiment was arranged at a factorial (3 x 3) using Completely Randomized Design (CRD) with 6 replications. The first factor was the dose/volume of liquid organic fertilizer treatment in concentration of 3 cc L-1 of water (D) consisting of 3 levels i.e. d1 = 300 mL; d2 = 400 mL; d3 = 500 mL, while the second treatment was the interval of liquid organic fertilizer (I) application consisting of 3 levels i.e. i1 = 2 weeks; i2 = 3 weeks; i3 = 4 weeks. Seedling emergence test, germination rate, vigor index and seed germination percentage were measured and the growth parameters such as the plant height increase, plant midrib girth, number of midrib increase, and number of leaves were observed. The results showed that scarification at the embryo part (s4) resulted in the best seed germination percentage of the short age sugar palm at around 99.81%. Combination treatments between 500 mL dose of liquid organic fertilizer in concentration of 3 cc L-1 of water with the interval of 2 weeks (d3i1) produced the best seedling growth of the short age sugar palm.
