This study aims to improve the growth, yield, and quality of LP-VoS bulbs by applying bokashi fertilizer from goat manure and regulating the duration of water supply with a sprinkler irrigation ...system. This research is a field that arranged in split-plot design. The main plot is the duration of irrigation water supply, consisting of three levels, 0.5; 1,0; and 1.5 hours. The subplot is giving organic fertilizer bokashi goat manure, which consists of two kinds, namely: without bokashi fertilizer and the addition of bokashi fertilizer 15 t.ha-1. Each treatment was repeated three times so that in total, there were 18 experimental plot units. The results showed that the duration of irrigation 0.5 hours at intervals of 3 days, followed by the application of 15 t.ha-1 bokashi organic fertilizer could increase the bulb circle of 'Lembah Palu' varieties.The use of bokashi organic fertilizer 15 t.ha-1 could increase soil moisture so it can growth, yields, and quality of shallot bulb. The duration of irrigation with a sprinkler system for 0.5-1.0 hours at intervals of 3 days could result in the growth of total dry weight and total leaf area per plant as well as the number of tubers per clump, fresh weight of tubers per clump and yield of tubers per hectare higher than treatment of water for 1.5 hours at intervals of 3 days. Water supply regulations and the use of bokashi organic fertilizers can increase the growth, yield, and quality of LP-VoS bulbs on dryland. For the cultivation of‘Lembah Palu’ varieties of shallots in dry land, it is necessary to apply organic fertilizers to increase the soil water content for increased production and quality.
ABSTRACT Campomanesia adamantium (Cambess.) O. Berg (guavira) is a native plant of the Cerrado and Pantanal, which has several medicinal activities and fruits with a unique flavor rich in vitamin C. ...The species does not have defined cultivation methods, requiring studies to increase biomass production. An alternative is the use of organic residues that can influence the chemical, physical and biological characteristics of soils and consequently increase plant production. Thus, the objective was to evaluate the effect of different organic residues and bokashi, on the biomass production of plants and on the levels of phenols, flavonoids and antioxidant activity of tea from the leaves of guavira. Five substrates were studied in pots and protected environment: soil; soil + rice husk chicken manure; soil + sawdust chicken manure; soil + castor bean cake; soil + Organosuper® with or without the use of Bokashi in a 5x2 factorial scheme, in a randomized block experimental design. It was observed that the rice husk chicken manure can be used to increase the initial growth and biomass production of guavira keeping the leaves antioxidant activity tea stable. The use of bokashi benefits the growth of guavira only when no other organic residue is added to soil.
Abstract
Organic liquid fertilizers (OLF) are made up of essential plant nutrients, as well as beneficial microbes that assist in the recycling of organic waste. The purpose of this study was to ...determine the macronutrient content of organic liquid fertilizers and compare the growth performance of mustard greens under Wick System hydroponic conditions. Market wastes also known as vegetable wastes, were utilized to produce organic liquid fertilizers and compare it to commercial fertilizer (Nutrient Solution, NS). The vegetable wastes were fermented with water and Effective Microorganisms (EM) Bokashi separately. The ratios used for fermentation are 2 kilograms of vegetable wastes, 0.5 litres of water and 100 grams of EM Bokashi. A parameter study on the OLF and OLF with Bokashi to determine the nitrogen (N), phosphorus (P) and potassium (K) were done. Thereafter, four Wick System (pure water, OLF, OLF with Bokashi and NS) were setup to monitor the growth performance of mustard greens twice a week. The organic liquid fertilizers are produced after 40 days of fermentation and used at a dilution of 1: 10 in the hydroponic system. The OLF and OLF with Bokashi showed the ranges of pH values as 5.1 and 4.6 respectively. The results for the hydroponic system showed that OLF demonstrated the best growth performance. The number and size of leaves and the height of the plants in the NS hydroponic system were almost similar to the plants in OLF hydroponic system. The colour of plants in OLF changed slightly to yellowish green towards the end of the growing season. The life spent of mustard greens in OLF with Bokashi hydroponic system was the least compared to other hydroponic system. This study showed that organic liquid fertilizer is as effective as commercial liquid fertilizer. Considering, it has all the nutrients that plants need to grow.
The main aim is to describe plant production systems and introduce bokashi technology for the advanced utilisation of food waste in Europe. The secondary objective is to demonstrate that the new ...Bokashi technology fertiliser products for field crops can improve soil fertility, plant health, yield and food quality in Europe. Bokashi technology is a straightforward yet innovative technology to recycle and valorise various kinds of biowaste into a nutrient-rich product that can be used as an organic fertiliser. Bokashi technology is a method for treating biowaste in general and food waste in specific, using controlled lactic acid fermentation (LAF) under anaerobic conditions. The term is based on a traditional Japanese method of the same name. The acidic and anaerobic environment quickly suppresses the viability of pathogens so even contaminated biowaste can be recycled. The Bokashi technology is almost absent in Europe at the moment. Conclusion: Bokashi technology - coming from Asia (Japan) - is an innovative technology to improve soil fertility, plant health, yield and food quality. This technology has a huge potential to be applied in Europe, but the right methodology should be developed based on the knowledge of temperature regimes for effective microorganisms that will influence the crop production.
Soil-borne diseases can cause significant crop losses and should be tackled sustainably in agroecosystems. Increasing the capacity of soils to suppress the effects of soil-borne diseases (soil ...suppressiveness) is an important tool in sustainable crop production. Soil suppressiveness can be improved by adding organic amendments to the soil for multiple years, but the effects can vary greatly depending on the processing method of the organic amendment (composted, fermented, or fresh material) and the time since application. To test these impacts we conducted two bioassays using the Lepidium savitum (cress) – Pythium ultimum model system. We tested the disease suppression capacity of sandy arable soil from a field experiment where fresh plant material, compost, or Bokashi (fermented amendment), all originating from the same plant material had been applied for two consecutive years across 10 field sites subject to conventional farming. In addition, the effect of short term application on soil suppressiveness was tested right after applying the same organic amendments to control arable sandy soil from 2 sites from the field experiment. Field sites strongly differed in cress growth independent of the organic amendment treatments. Absence of field effects in the sterilized soil and their soil chemical characteristics suggested differences in inherent soil pathogen load between the field sites. Focussing on sites with low inherent pathogen load we found no significant impact of long term organic amendment application on either cress weight or soil suppressiveness. However, short term application of Bokashi did significantly promote soil suppressiveness. This effect can likely be attributed to the increased metabolic activity of the soil's microorganisms in response to Bokashi, which contains more easily decomposable compounds as compared to the other soil amendments, together with Bokashi microorganisms that survive the fermentation and are activated in the aerobic soil condition. Our results suggest that Bokashi could promote the suppression of soil-borne diseases by stimulating the locally adapted soil microbiome but the longevity of this effect requires further field tests.
•Fermented, composted and fresh organic amendments differ in soil suppressiveness.•Fermented organic material can improve soil suppressiveness in short term.•High soil pathogen load limits the impact of amendments on disease suppressiveness.
The purpose of this study was to analyze the effect of bokashi (Cow) fertilizer on increasing soil nutrients and the growth of medicinal plants (Biopharmaca). The research method was a completely ...randomized design (CRD) with 3 treatments which were repeated 3 times. The type of bokashi fertilizer is cow dung, while the medicinal plants used are ginger and turmeric. Data analysis was performed using ANOVA (Analysis of variance) and 5% F test to determine the effect of treatment. The research findings showed that the application of organic matter bokashi cow dung succeeded in increasing soil nutrients consisting of H2O, C-Organic, P2O5, K2O, and CEC along with the increase in the concentration of bokashi. Giving bokashi cow dung had a significant effect on plant height, the number of leaves, and bulb weight of Biopharmaca plants at 30 DAP and 60 DAP measurements. It was concluded based on the results of the study that goat and cow dung bokashi can be used to increase soil nutrients such as KCl, C-Organic, N-Total, P2O5, K2O, and CEC. Besides, bokashi fertilizer can also be used for the growth of biopharmaceutical plants where plant height, number of leaves, and bulb weight of medicinal plants are indicators used.
Biochar, as a soil amendment, has been reported to improve plant growth by increasing soil moisture and retaining nutrients. In a previous 12-week greenhouse study with highbush blueberry ( Vaccinium ...hybrid), we found that amending soil with biochar alone or in combination with bokashi (fermented wheat bran) increased plant growth relative to unamended soil. The biochar was produced from mixed conifer species during conversion of wood to energy. In the current study, we aimed to validate the greenhouse findings under field conditions in western Oregon. The specific objectives of this 2-year study were to determine the effect of amending soil with biochar or a combination of biochar and bokashi on growth and early fruit production during establishment of northern highbush blueberry ( Vaccinium corymbosum L.). To achieve these objectives, we transplanted ‘Duke’ blueberry plants into soil that was either unamended or amended with biochar or 4:1 (v/v) mixtures of biochar and bokashi or biochar and douglas fir Pseudotsuga menziesii (Mirb.) Franco sawdust. Each amendment was either applied in the planting hole or incorporated into the row. A treatment with douglas fir sawdust incorporated into the row was also included and represented the industry standard for the region. Plants grown in soil amended with biochar (in the planting hole or row) had 40% to 74% greater total dry weight at the end of the first growing season and 70% to 82% greater fruit yield in the second season than those grown with no amendments or in soil amended with sawdust. However, leaf Mg concentrations were lower with biochar, suggesting it could limit Mg uptake in blueberry. Soil amended with sawdust, on the other hand, was higher in organic matter, microbial activity, and wet stable aggregates than the other soil treatments but resulted in lower leaf N concentrations during the second year after planting. Unlike in the greenhouse study, biochar had no effect on root colonization by mycorrhizal fungi, and there was no benefit to using biochar with bokashi. Adding 4 L of biochar to the planting hole was considerably more economical than applying it to the row and cost $1320/ha less than the industry standard of incorporating sawdust in the row. These findings indicate that biochar is a promising soil amendment for commercial production of highbush blueberry.
