Co-composting of physic nut (Jatropha curcas) deoiled cake with rice straw and different animal dung
Bioresource Technology, 2011
To address the dispensing of this growing volume, a study on utilization of jatropha (Jatropha curcas) deoiled cake through compost production was carried out. The deoiled cake was composted with rice straw, four different animal dung (cow dung, buffalo dung, horse dung and goat dung) and hen droppings in different proportions followed by assessment, and comparison of biochemical characteristics among finished composts. Nutrient content in finished compost was within the desired level whereas metals such as copper, lead and nickel were much below the maximum allowable concentrations. Although a few finished material contained phorbol ester (0.12 mg/g), but it was far below the original level found in the deoiled cake. Such a study indicates that a huge volume of jatropha deoiled cake can be eliminated through composting.
Purpose In the current scenario, food wastage is a significant concern throughout the world. This food wastage may convert to compost, and that compost may apply in the agriculture field for the better yield of crops. In this context, a field study conducted on the effects of compost prepared from food wastage on the yield of cabbage, cauliflower, and radish. Method The experiment consisted of twelve treatments and twelve control plants of all the plants. Field soil of both control and treatment plots were analyzed by standard methods. Standard methods took different morphological and chemical parameters of all the plants. Results Results indicated that compost from food waste increased soil fertility. The application of manure was significantly (p<0.01) superior over the morphological and biochemical properties of the control group plants. The application of compost increased leaf relative water content and decreased the electrolyte leakage in all the plants. The yield of cabbage (control-0.00 t•ha-1 , treatment-37.05 t•ha-1), cauliflower (control-10.16 t•ha-1 , treatment-22.36 t•ha-1) and radish (control-7.30 t•ha-1 , treatment-20.33 t•ha-1) were significantly higher in the treatment group than the control group. The yield increment in percentages of cabbage, cauliflower, and radish was infinite %, 220.08 %, and 278.49 %, respectively. The day in terms of time, compost, and their interaction has a significant effect on the better health of cabbage, cauliflower, and radish, and more yields achieved. Conclusion Therefore, food waste is used for making compost, which is helpful for organic cabbage, cauliflower, and radish production in a subtropical condition.

Modern agriculture faces to new challenges and problems. Application of organic waste compost represents new possibilities to improve soil organic matter and thus reduce the risk of soil degradation and improve significantly crop yield. This study was conducted to determine the effect of various compost-based Jatropha by-products on soil properties and sorghum (Sorghm bicolour L.) Moench) growth and production parameters. The treatments of the study corresponded to 13 formulations of Jatropha curcas based composts and a control treatment, which did not receive any application. The study showed that Jatropha by-products amendment could effectively raise soil fertility by increasing pH and nutrient contents and improved sorghum growth and production parameters. The results also showed positive and significant correlations between panicles yield and seeds yield as well as straws yield. Positive and significant correlations were recorded between seeds yield and straws yield and weight of 100 seeds. These correlations between the different parameters are important of simultaneous improving of growth and crops yield of sorghum. The ACP performed based on measurement parameters permitted to identify the appropriate formulation for any interest parameter. The CAH distinguished four classes of composts among which Jatropha biomass-based composts with groups 3 (BM_S and BM+BV) and 4 (BM+CP) are particularly interesting as these treatments are strongly associated with seeds, straw and panicle yields, sorghum spike height

This study was conducted to assess the effect of microbial inoculation in Jatropha cake composting with different vegetable waste. The microbial inoculums composed of fungal strains (Aspergillus awamori, Aspergillus nidulans, Trichoderma viride, Phanerochaete chrysosporium) and bacterial inoculums (Pseudomonas striata as phosphorus solublizer and Azotobacter chroococcum as nitrogen fixer) were added to the compost mixture after the thermophilic phase was over for bioaugmenting of Jatropha cake under aerobic and partial anaerobic conditions. Addition of both fungal and bacterial inoculum with mixed substrate (Jatropha cake + vegetable waste) during composting (aerobic and partial anaerobic) showed, better results as compared to compost with only fungal inoculants. Increased enzymatic activity initially, during composting (like dehydrogenase, alkaline phosphatase activity and FDA) proved role of inoculated microbes in rapid decomposition. Analysis of compost (with both bacterial and fungal inoculum) showed presence of high humus (12.7%), humic acid (0.5%), fulvic acid (5.68%), soluble protein content and low C/N ratio. Decreased in concentration of extractable metals (Cu, Fe and Mn) were recorded at maturity in all the substrate composts. The C/N ratio was significantly correlated to parameters like humic acid, humus, fulvic acid, protein and also microbial activity parameters. We conclude that the composting of de-oiled Jatropha cake with different vegetables waste could be feasible and sustainable approach in recycling of agricultural and industrial residues in huge quantities.
Composting of municipal solid waste (MSW) is a good option for solid waste recycling, but its use by the farmers is limited because of its very low nutrient status. Aims: The study aimed at nutrient enrichment of marketed MSW compost by using some organic materials and evaluating the influence of nutrient enriched MSW compost on yield and nutrient content of cabbage (Brassica oleracea L.). Place and Duration of Study: MSW compost amendment, field experiment and nutrient analysis were carried out at Bangladesh Agricultural University (BAU), Mymensingh during October 2017 to June 2018. Methodology: We prepared three types of amended compost by mixing 20% mustard oil cake (MOC), and 30% poultry manure (PM) or cow dung (CD) or sugarcane press mud (SPM) with 50% MSW compost. A liquid culture of Trichoderma viride was inoculated to every type of compost. The field experiment was conducted to evaluate the performance of the amended MSW composts on Original Research Article

A field experiment was conducted during Rabi season in the experimental field of BCSIR to see the effects of fresh and digested cowdung (CD) and poultry litter (PL) bio-slurry on the growth and yield of cabbage (Brassica oleracea). The experiment was laid in a Randomized Complete Block Design (CRBD) with six different treatments including control. Cabbage variety Atlas-70 was transplanted at the age of 35 days and was harvested at 120 days. Plant height, circumference, marketable weights and whole plant weight were examined to perceive the effects on the growth and yield of cabbages. The experiment revealed that both digested PL and CD bio-slurry had a significant effect (P < 0.01) on the growth and yield components of cabbage. Increased plant growth and yield were in the order of digested PL bio-slurry > digested CD bio-slurry > fresh PL > fresh CD in combination with recommended dose of fertilizers (RDF). Among the treatments, the highest head yield of cabbage (97.6 t ha-1) was obtained from RDF + 5 t ha-1 digested PL bio-slurry which was 366 % higher than the control.
Bio stabilization of Jatropha Curcas Cake to Bio fertilizers through Vermicomposting
In this present study, Jatropha Carcus cake, a by product from the bio diesel production process was destabilization through vermicomposting to produce bio fertilizers. Jatropha Curcas cake was vermicomposted over a period 30 days using Eisenia Fetida earthworms. The nitrogen, phosphorous and potassium (NPK) content in the cake was continuously monitored using AOAC methods and the same was done for the leachate (vermiwash) produced during the vermicomposting process. The NPK content in the Jatropha Curcas cake increased with increase in the vermicomposting period with a 35% increase in N, 58% increase in P and a 98% increase in K. Furthermore, the vermiwash produced had an NPK with a composition of 2.1%, 0.75% and 0.51% respectively. The bio stabilization of the Jatropha Curcas cake through vermicomposting to bio fertilizers.
The efficacy of jatropha (Jatropha curcas L.) seed cake as an organic fertilizer
African Journal of Agricultural Research, 2018
Studies to evaluate the efficacy of Jatropha curcas L. (Jatropha) seed cake as an organic fertilizer were carried out at Bunda College of Agriculture during the 2010/2011 growing season using an on-station experiment. The major objective was to evaluate the efficacy of Jatropha seed cake as an organic fertiliser. The field experiment was laid in a 3 × 3 design with 3 levels of Jatropha (0, 92 and 184 kg N/ha corresponding to 0, 2875 and 5750 kg DM of Jatropha seed cake, respectively) and 3 levels of inorganic fertilizer (0, 23 and 46 kg N/ha). Field results showed that maize yields responded to the amount of Jatropha seed cake while inorganic fertilizer rate and the combination of Jatropha seed cake and inorganic fertilizer (at the same level of Jatropha seed cake) did not affect the grain yield of maize. The best performer in terms of grain yield was a treatment combination of 5750 kg/ha of Jatropha seed cake and 23 kg N/ha of inorganic fertilizer which produced a grain yield of 2483 kg/ha. However, this was comparable to 2331 kg/ha produced by the combination of 2785 kg/ha of Jatropha seed cake and 46 kg N/ha of inorganic fertilizer. The grain yield of sole Jatropha 5750 kg/ha was 2126 kg/ha. The grain yield of full rate of inorganic fertilizer (23:21:0+4S + urea) application was 2853 kg/ha. It can be concluded from this study that sole application of Jatropha seed cake has a potential of producing grain yield comparable to full rate inorganic fertlizer application.
