Effects of cattle dung from farms with different feeding strategies on germination and initial root growth of cress (Lepidium sativum L.)

Dispersão e persistência de leguminosas forrageiras tropicais após ingestão por bovinos

“…A germinação das sementes das leguminosas analisadas pode estar relacionada, principalmente, com a eficiência da quebra de dormência, através da passagem pelo trato digestivo dos bovinos e pela influência climatológica e nutricional que as leguminosas foram submetidas (JONES; SIMÃO NETO, 1987). Além disso, há presença de compostos tóxicos em fezes bovinas que atuam inibindo a germinação de sementes (HOEKSTRA et al, 2002).…”

Time Efficient Co-composting of Water Hyacinth and Industrial Wastes by Microbial Degradation and Subsequent Vermicomposting

“…This increment in potassium was due to acid produced by the microorganisms which plays major role in solubilisation of insoluble potassium [68]. It has been suggested that earthworm processed residue contains higher concentration of exchangeable K due to enhanced microbial activity during vermicomposting, which consequently enhances the rate of mineralization [68]. During composting of distillery sludge percent increase in total potassium was noted maximum in all five treatments after 20th day (Figure 8).…”

“…Out of five treatments of three waste maximum increments in TK was noted in DS1, DS2, PS4 and control. This increment in potassium was due to acid produced by the microorganisms which plays major role in solubilisation of insoluble potassium [68]. It has been suggested that earthworm processed residue contains higher concentration of exchangeable K due to enhanced microbial activity during vermicomposting, which consequently enhances the rate of mineralization [68].…”

Microbial succession in a fermenting of wild forest noni (Morinda coreia Ham) fruit plus molasses and its role in producing a liquid fertilizer

“…Ten tomato seeds were distributed evenly on the filter paper and the Petri dishes were incubated in the dark at room temperature for 72 hrs. Distilled water was used as a control set for the testing of seed germination (Hoekstra et al 2002;Fuentes et al 2004). This experiment was conducted in three replicates.…”

“…The seed germination bioassay was evaluated by computing the germination index (GI), a factor derived from the relative seed germination and the relative root elongation. The % GI was calculated according to the formula of Hoekstra et al (2002). One-way analysis of variance was used followed by the Duncan' multiple comparison test to analyze significant differences between treatments using the SPSS version 10 for Windows.…”
