“…This can be due to higher nutrient content (nutritional effect) of CT-1. Similar results were also observed by Shrestha et al (2012), where it was noted that growth benefit of compost tea was not directly biological in nature. They further observed that the high dose of compost extract may have had a positive impact on plant growth.…”

“…In addition, the FSC-RHB substrate may have provided better plant anchorage and nutrient uptake hence the more chlorophyll content found in the leaves. The direct cause of improved plant growth following compost extract (compost tea) application is often not clear (Shrestha et al 2012). According to Merrill et al (1997), the mineral nutrients extracted from compost can improve soil fertility directly.…”

Purpose Faecal sludge (FS) has been co-composted with many organic solid wastes globally. Agricultural wastes, such as oil palm empty fruit bunches (EFB) and cocoa pod husks (CPH), have received very little research attention as far as combining with FS is concerned. This study aimed at co-composting these wastes at different ratios to produce safe compost for use as soilless medium for raising tomato transplants. Methods Dewatered FS (DFS) was mixed with shredded EFB and CPH at five different ratios: 1DFS:1EFB, 1DFS:1CPH, and DFS:EFB:CPH in ratios of 1:1:1, 2:1:1, and 2:2:1 and composted for 3 months. Select physicochemical parameters and pathogens were monitored every fortnightly and 3 weeks, respectively. Results Maximum temperatures obtained ranged 46.8-54.5°C. Though these temperatures were lower than sanitizing temperatures prescribed by USEPA, no E. coli was found in any of the piles at the end of composting. The ratio 2DFS:2EFB:1CPH was found to be the safest formulation and hence was used to grow tomato under greenhouse conditions. Tomato seeds were sown in three different growing media: 100% FS-based compost, 100% rice husk biochar, and 50% FS-based compost-50% rice husk biochar mix. Conclusion Results showed that FS-based compost was a suitable growing medium for tomato. Further studies into the optimal rate and frequency of application of compost teas on tomato are recommended.

“…These organic fertilizer solutions contain a high amount of mineral nutrients, beneficial microorganisms (Edwards et al, 2010), and growth promoting agents such as humic and fulvic acids (Arancon et al, 2007). Besides, compost and vermicompost teas) have been used as nutrient source in several hydroponic crops (Márquez et al, 2013;Preciado et al, 2014), in addition that can be applied using pressurized irrigation under protected agricultural conditions as in a greenhouse (Shrestha et al, 2012). Moreover, the production costs of organic nutritive solutions are lower compared to those of traditional inorganic fertilizer solutions (Wrzodak et al, 2012).…”

“…Berat gabah kering giling, gabah per ubinan atau gabah per hektar, serta berat gabah per 1,000 butir pada petak yang diaplikasikan ekstrak kompos paling tinggi dan berbeda nyata dibandingkan dengan dua perlakuan lainnya (Tabel 2 dan 3). Shrestha et al (2012) menyatakan cara kerja ekstrak kompos dalam meningkatkan produksi tanaman melalui peningkatan mineralisasi atau melalui ameliorisasi tanah. Liu et al (2012) menyatakan N yang diserap padi ratun 57-76% akan digunakan untuk pembentukan bunga dan dimanfaatkan untuk pembentukan bulir padi ratun.…”

The advantages of ratooning rice are to save water, cost production, labor, preparation time for planting and harvesting, but the ratooning productivity is still low. This research aimed to study the effect of the bioinsecticide and compost extract on ratooning rice production and insect populations. The ratooning rice was applied by bioinsecticide, compost extract, and combination of bioinsecticide and compost extract with dose 2 L ha-1 per application, respectively. Data of agronomic variables were statistically analyzed using analysis of variance, whereas insect pest population data were analyzed using Chi Square test. The seedling height of ratoon applied by compost extract was the highest among treatments. The number of productive tillers per clumps and rice production on plot applied by compost extract were higher than the insecticide treatment. At the age of 17 day-ratooning rice, application bioinsecticide reduced the population of insect pests, such as Ciccadulina bipunctata, Recilia dorsalis, Nilaparvata lugens, and Nephotettix nigropictus. Thus, application of compost extract tended to improved the growth and production of the ratooning rice, while the bioinsecticide decreased the insect pest population.<br />Keywords: Beauveria bassiana, rice growth, production
