Abstract

The problem of severe weed infestation often arises during the early phases of establishment of oil palm field due to the spacing requirement and growth habit of young oil palm plantation until later years when the canopy closes. This study was conducted at Ala, Akure-North Local Government Area, Ondo State, Nigeria, to investigate the composition of weed species and their distribution in fruit vegetable-juvenile oil palm intercrop. The fallow alleys within the immature oil palm were intercropped with 2 accessions of tomato (NGB 01665 and NG/AA/SEP/09/053) and eggplant (NGB 01737). The sampling of the weed species was carried out with a quadrat (0.25 m2). Weed species parameters and the Diversity Index (D) were quantitatively analyzed. The results revealed that members of Asteraceae and Poaceae gave the highest weed species at 3 and 6 weeks after intercropping (WAI) (17.857% and 19.04%) respectively. A total of 23 and 16 were found at 3 and 6 WAI, while the least diversity index of 0.734 was recorded in the immature oil palm/tomato (NGB 01665) plot at 6 WAI. Farmers should be persuaded to simultaneously intercrop fruit vegetables within the alley of juvenile oil palm, particularly at the earlier years prior to closure of the oil palm canopy.

Abstract

The participation of women in the agricultural sector has increased in the last two years, attributed to the population growth and household economy. Therefore, this research examined the internal and external factors to the women farmers’ participation. This research was conducted in Situ Gede Village, West Bogor Sub-district, Bogor City and involved women farmer group consisting of 36 members. The primary data were gathered by interviewing respondents using a questionnaire, while the secondary data were obtained from literature review and various related institutional sources. The data were examined using the Pearson’s Product-Moment Correlation analysis to investigate the relations between the internal and external factors to women farmers’ participation. The results of this study have revealed the internal factors related to women farmers’ participation, such as age, farm experience and decision making. Meanwhile, the external factor related to the participation of women farmers is the access to counseling, meaning that some of these aspects need to receive the government’s attention, especially in terms of access to education related to the counseling method, time and substance of counseling.

Abstract

Soilless culture system (SCS) production is preferred because it is more hygienic and highly nutritious and free of chemical pesticides. However, the application of organic fertilizers in SCS for green vegetable cultivation is still rarely used. This study was to test various growing media compositions and vermicompost rates on green lettuce's nutritional quality. Four types of growing media (using the mixture of cocopeat, zeolite, rice husk biochar and sand) and five levels of vermicompost rates (50-250 g pot-1) were tested. The greatest total fresh weight and marketable yield were found using 55% cocopeat, 30% rice husk biochar and 15% sand with a vermicompost rate of 250 g pot-1. The highest nutritional quality of green lettuce as measured by the highest content of chlorophyll A, B, the total chlorophyll and calcium (Ca) was found in the composition of cocopeat 55%, zeolite 30% and sand 15%. As was, the highest mineral content of of potassium (K) and phosphorus (P). Good quality lettuce was found in growing media using 30% biochar with a vermicompost rates of 200-250 g pot-1 and growing media using 30% zeolite with a vermicompost rates of 150-200 g pot-1. Thus, the admixtures of biochar and zeolite into the cocopeat substrate for the soilless culture system of green leafy lettuce significantly affected yield and nutritional quality.

Abstract

The bleaching process at the crude palm oil (CPO) refinery stage is one of the processes sufficient to determine the quality of the cooking oil produced. CPO is refined to eliminate the unacceptable substances before consumption. The process produces spent bleaching earth (SBE) and deoiled bleaching earth (DBE) classified as hazardous and toxic material waste. However, according to several studies, SBE and DBE have the potential as filler materials in NPK fertilizers. This study aimed to study the effect of SBE and DBE filler-based NPK fertilization on the soil nutrient status and growth characteristics of soybean, thereby determining if the SBE and DBE materials can be used to replace some of the filler components in the NPK fertilizers. The study was a single factor experiment arranged in a Randomized Complete Block Design (RCBD) consisting of four blocks as replications. The treatments tested were fertilization of 10% bentonite clay mineral filler-based NPK (control), 5% bentonite clay mineral + 5% SBE filler-based NPK and 5% bentonite clay mineral + 5% DBE filler-based NPK. The data were analyzed using ANOVA and tested using LSD test at a 95% confidence level. The results showed that the SBE and DBE materials could partially replace the filler components in bentonite clay filler-based NPK fertilizers, which were shown to have the same effect on soil chemical properties and levels of heavy metals after treatment, levels and uptake of N, P, K, Ca and Mg in plants tissues and growth characteristic in the form of total dry weight.

Abstract

The high demand of rice is fulfilled by intensification, particularly with the use of chemical fertilizer that allegedly causes land and environmental problems in a long term. As public awareness of environmental health rises, more rice fields are managed organically and semi-organically, but there are still many that manage rice fields inorganically. Assessment of soil quality of the three types of rice field management is important to prove that organic rice fields have better soil quality than semi-organic and inorganic rice fields, as well as to evaluate soil conditions on the location. This research was conducted in Girimarto, Wonogiri, Indonesia, using a descriptive explorative method with a survey approach on three points of each management system of rice fields, which are organic, semi-organic and inorganic rice fields. Statistical analysis was performed by Pearson correlation analysis and principal component analysis (PCA) to determine the indicators affecting soil quality, which are called the minimum data set (MDS). There were selected indicators in this research, including total microbes, base saturation, cation exchangeable capacity and organic carbon. Based on the results of the study, organic rice fields have the best soil quality with a score of soil quality index (SQI) of 2.3, compared to semi-organic rice field SQI (2.2) and inorganic rice field SQI (1.7). The results indicate that organic management contributes to better soil quality and environment.

Abstract

Cultivating annual crops in the high upland has the potential to increase avalanche and land erosion. Therefore, chrysanthemum extensification from high upland to medium upland can create sustainable agriculture. The differences between high upland and medium upland are microclimate and soil type. Meanwhile, the effect of soil type between the high upland and the medium upland on the chrysanthemum spray type quality is unknown. The study aimed to determine the effect of different soil types on the quality of chrysanthemums when planted in high upland. The study used a split plot design with two factors. The first factor was the type of soil, such as Andosol from the high upland and Latosol from the medium upland. The second factor was the chrysanthemum varieties, such as Yastayuki (white flower), Arosuka Pelangi (yellow flower) and Socakawani (red flower). The results showed that both Andosol and Latosol soil types could produce the same quality of chrysanthemum in all varieties when planted in high upland. The quality aspects of chrysanthemum were the plant height, the stem diameter, the number of flowers and flower color. Consequently, we could extend the cultivation of chrysanthemum in medium upland by using Latosol type soil.

Abstract

Snake fruit (Salacca zalacca (Gaertner) Voss) is one of indigenous fruits from Southeast Asia that has been consumed for its antioxidant contents. Improving the fruit quality might increase its benefits for human health. This study aims to analyze fruit morphology, antioxidant activity, total phenolic and flavonoid contents of the fruit applied with goat manures and Bacillus velezensis B-27. The research used two-factor Randomized Complete Block Design (RCBD) with three blocks as replications. The first factor is the level of goat manure application i.e. 0 kg plant-1, 5 kg plant-1 and 10 kg plant-1, while the second factor is the bacteria application i.e. applied with Bacillus velezensis B-27 and without Bacillus velezensis B-27. The research was conducted in June until December 2019 at Turi, Sleman, Yogyakarta, Indonesia. Fruit length, diameter and shape were measured as morphology parameters. Antioxidant activities were measured using 2,2-Diphenyl-1-picrylhydrazyl, whereas flavonoid and phenolic contents were determined by the aluminium-chloride colorimetric and Folin-Ciocalteu methods, respectively. Means of each parameter were analyzed using ANOVA, continued with the Tukey’s HSD test at a 5% significance level. The result showed that the application of 10 kg goat manure per plant with bacteria increased the fruit length (76.78 mm) and the diameter (62.72 mm). Addition of 10 kg goat manure per-plant combined with Bacillus velezensis B-27 gave the highest antioxidant (IC50 of 37.83 µg.mL-1), flavonoid (5.35 mgGAE.100 g-1) and total phenolic contents (44 mgQE.100 g-1).

Abstract

The revitalization of farmer organizations has become the central paradigm in agricultural development. In Indonesia, increasing farmer participation in farmer groups, associations and cooperatives is the strategy to revitalize farmer organizations. This study aimed to determine the factors influencing farmers' participation in farmer groups, associations and cooperatives. This study employed data from the Sugarcane and Tobacco Plantation Farm Household Survey in 2014, consisting of 8,831 (70.73%) sugarcane farmers and 3,645 (29.27%) tobacco farmers. Logistic regression analysis was used to identify the factors contributing to farmers' participation in each organization. The results showed that harvest area, access to extension and contract farming positively affect farmers’ participation in organizations. Farmers' age and education positively affect their participation in associations and cooperatives but do not significantly affect their group participation. Land tenure has an ununiform effect on farmer participation in each organization. Tenant farmers are less likely to participate in farmer groups and cooperatives, but they tend to participate in associations. Meanwhile, the owner farmers are less likely to join cooperatives. Government support positively influences farmer group participation, shows a negative effect on participation in associations and has a non-significant effect on participation in cooperatives. Finally, farmers' wealth gives a positive effect on their participation in cooperatives, a negative effect on their participation in associations and a non-significant effect on farmer groups. These results depict that farmer groups are more inclusive than cooperatives and associations.

Abstract

There are factors contributed to the growth and development of fruit crop seedling. Microbes are well known as plant growth promotors such as symbiotic mycorrhizae and antagonist fungi, Trichoderma spp. The main objective of this experiment is to find out the best medium composition enriched by beneficial microbes to improve papaya seedling growth. The experiment was conducted at Sumani Experimental Station, Indonesian Tropical Fruit Research Institute, Solok, West Sumatera, Indonesia from August until December 2017. The experiment was arranged in a Randomized Complete Block Design with ten treatments and three replicate blocks. The treatments were ten combinations of media for papaya seedling growth enriched by plant growth promotor microbes. In this experiment, medium soil with additional manure, rice husk charcoal and compost (single or combination) combined with mycorrhizae were used. Also, the effect of Trichoderma sp. enrichment into media composition were tested in this experiment. Treatments SCRMc and SCRMcT; with its complexity; were the best media composition to promote papaya seedling growth. These treatments resulted in best performance of plant height, stem diameter and number of leaves of papaya seedlings. The additional of Trichoderma sp. into medium did not show beneficial effect for all parameters in this experiment.

Abstract

An increase in corn productivity is not always followed by an increase in farmer income and welfare. The sustainability of farms must be supported by its economic viability including the marketing aspect. This study aimed to analyze the marketing of corn in Sigi Regency, Central Sulawesi Province. This research applied qualitative and quantitative methods. Marketing channel and marketing margin were analyzed descriptively, while farmer share was analyzed quantitatively using variance analysis (ANOVA). The results have shown three types of corn marketing channels, namely: 1) channel I, consisting of farmers-consumers, 2) channel II, covering farmers-collectors, traders-retailers and traders-consumers and 3) channel III, including farmers-collectors and traders- feed industries. Channel II has the highest marketing margin, followed by channel III and I, respectively. The intermediaries determine marketing costs that affect marketing margin and farmers’ shares. Channel I has the highest farmers’ shares, followed by channel III and channel II, respectively. The results of the significant difference test have revealed a difference in farmers’ shares in the marketing channels; and hence, the choice of marketing channel significantly determines the farmers’ shares. Therefore, farmers should shorten the marketing chain and strengthen their bargaining position by activating groups. Meanwhile, the government can play an active role so that farmers can have an access to strengthening capital and marketing.
