The influence of humic acids derived from earthworm-processed organic wastes on plant growth.
The incorporation of both types of vermicompost-derived humic acids, into either type of soilless plant growth media, increased the growth of tomato and cucumber plants significantly, in terms of plant heights, leaf areas, shoot and root dry weights.
Pig manure vermicompost as a component of a horticultural bedding plant medium: effects on physicochemical properties and plant growth.
This experiment was designed to characterize the physical, chemical and microbial properties of a standard commercial horticultural, greenhouse container, bedding plant medium that had been substituted with a range of increasing concentrations of pig manure vermicompost and to relate these properties to plant growth responses.
Influence of earthworm-processed pig manure on the growth and yield of greenhouse tomatoes
The eAects of earthworm-processed pig manure (vermicompost) on germination, growth, and yields of tomato (Lycopersicon esculentum Mill.) plants were evaluated under glasshouse conditions and some of the growth and yield enhancement resulting from substitution of Metro-Mix 360 with pig manure verMicompost could be attributed to the high mineral N concentration of the pig manure.
Effects of vermicomposts and composts on plant growth in horticultural container media and soil
Summary Vermicomposts, which are produced by the fragmentation of organic wastes by earthworms, have a fine particulate structure and contain nutrients in forms that are readily available for plant
Influences of vermicomposts on field strawberries: 1. effects on growth and yields.
Responses seemed not to be dose-dependent, since strawberries at one site grew fastest and yielded most in response to the 10 tha(-1) vermicompost application rate, whereas they responded positively and similarly to both the 5 and 10 tha-1 rates of applications at the other site.
The influence of earthworm-processed pig manure on the growth and productivity of marigolds.
Substitution of Metro-Mix 360 with any concentration of pig manure vermicompost, with all needed nutrients provided, increased the overall nitrate-nitrogen concentrations of the marigold leaf tissues at flowering stage and may be explained by nutritional factors.
Effects of vermicomposts produced from food waste on the growth and yields of greenhouse peppers.
Factors such as: an improvement of the physical structure of the potting medium, increases in populations of beneficial microorganisms and the potential availability of plant growth-influencing-substances produced by microorganisms in vermicomposts could have contributed to the increased pepper yields obtained.
Effects of vermicomposts on growth and marketable fruits of field-grown tomatoes, peppers and strawberriesThe 7th international symposium on earthworm ecology · Cardiff · Wales · 2002
Improvements in plant growth and increases in fruit yields could be due partially to large increases in soil microbial biomass after vermicompost applications, leading to production of hormones or humates in the verMicomposts acting as plant-growth regulators independent of nutrient supply.
DNA methylation, vernalization, and the initiation of flowering.
It is suggested that DNA methylation provides a developmental control preventing early flowering in Arabidopsis and Thlaspi ecotypes and that the control affects transcription of kaurenoic acid hydroxylase, a key enzyme in the gibberellic acid biosynthetic pathway.
Influences of vermicomposts, produced by earthworms and microorganisms from cattle manure, food waste and paper waste, on the germination, growth and flowering of petunias in the greenhouse
The effects of vermicomposts produced from three types of wastes on growth and flowering of petunias, an important U.S. flowering crop, are demonstrated.
