Potting soil mixes are the most important factors for quality production of flowers in floriculture. It becomes farmer’s first preference these days because flowering crops provide higher returns than traditional crops and its marketing offers both small and large scale growers a way to increase the level of sustainability on their farms. Globally, more than 140 countries are involved in cultivation of floriculture corps (Anonymous, 2006).
In the last few years farmers and nursery men are much concerned about the potting media as it play an important role in plant production. There is a continuing interest by using various agricultural by-products as an organic nutrient source for plants due to increasing awareness of environment-related issues, as well as the need to dispose off and use rising amounts of waste (Grigatti, 2008).
Organic materials from agriculture, forestry, green areas and livestock farming as well as residues from municipal and industrial waste are strongly recommended for use as renewable resources in pot production that palliate their harmful and negative impact on local and global environmental degradation. Peat is the most widely used substrate for potted plant production in the nurseries and accounts for a significant portion of the materials used to grow potted plants (Marfa et al., 2002; Ribeiro et al., 2007).Waste materials are the potential substitute for peat for sustainable horticulture production.
Dahlia is an important beautiful flower which belongs to family compositae and native from Mexico. It has attainted attention of many people all over the world by virtue of extra-ordinary quality of flowers and variation in colour and size. It has currently 35 renowned species and about 20,000 cultiv...

...different compositions. If such media is evaluated for better growth, development and quality flower production than it can be commercialized in nursery business.
The first objective of this research was to evaluate different potting mixes for the growth and flowering of Dahlia x ‘Figaro Improved’. This project was subjected to explore different types of media like silt, coconut coir, dust, sludge, spent mushroom compost, rice hull alone and in different compositions for the production of dahlia. Along with studying growth and flowering of dahlia the chemical properties of media like availability of nutrients, electrical conductivity (EC) and pH were also evaluated. Over all objectives was to develop an efficient protocol for mass propagation of dahlia cultivars in the most suitable media to enhance quality production for nursery growers and the local markets.
Two members of the group were instructed to visit the laboratory each day of the experiment to water and measure the plants (Handout 1). The measurements that were preformed were to be precise and accurate by the group by organizing a standardized way to measure the plants. The plants were measured from the level of the soil, which was flat throughout all the cups, to the tip of the apical meristems. The leaves were not considered. The watering of the plants took place nearly everyday, except for the times the lab was closed. Respective of cup label, the appropriate drop of solution was added to the plant, at the very tip of the apical meristems.
Although, this experiment is not concluded outdoors, it is provided with efficient light that promotes growth. It’s provided with soil, seed, fertilizer, water and NaCl solutions, to test how salinity effects plant growth.
The experiment was designed to test the hypothesis by planting an increasing number of genus Helianthus (sunflower) seeds in pots to see how they respond to increased density in limited space. Two replicates each of 2, 4, 8, 16, 32, 64, and 128 seeds were planted in similar size pots containing an equal mix of potting soil and perlite. All plants were kept in greenhouse conditions exposed to similar light and temperatures settings and were watered at equivalent intervals. At the end of the time period each pot was evaluated for number of seeds that had germinated as well as number of stems with blooms. Stems and blooms were cut and weighed.
Organic fertilisers and natural pest control methods minimise the impact of viticulture on the environment. In recent years there has been a considerable movement by some growers towards an organic approach. This is as a result of consumer driven trends and pressure to minimise the environmental impact of viticulture.
Furthermore, as the Liliaceae family is primarily ornamental they have a significant commercial value i...
Although considered faster and cheaper, this approach to providing other alternative resources to food is slowly but significantly drying up our plant and is compromising human health. Because of the increa...
Agriculture was the most important economic activity in America from the founding of Virginia in 1607 to about 1890. Although farming declined rapidly in relative economic importance in the twentieth century, U.S. agriculture continued to be the most efficient and productive in the world. Its success rested on abundant fertile soil, a moderate climate, the ease of private land ownership, growing markets for farm produce at home and abroad, and the application of science and technology to farm operations.
...ince, there is a need to use for advanced novel methods of culturing plant to furnish new means for quickly propagating,conserving of endangered species and also introducing exotic plants. The production of high quality planting material of exotic nature propagated from vegetative parts through tissue culture has created new opportunities in global trading. The exotic plants are advantageous for farmers;growers; nursery owners & rural employment. As exotic plants are restricted to their natural environment; the main benefit of tissue culture technology lies on production of high quality & uniform planting material that can be multiplied on a year round basis. The plant selected for such purpose is Stevia rabuadiana Bertoni. Objectives of study:

Composting is the process of biodegrading the waste material in which an enormous number of materials like hydrocarbons, nitrogenous compounds, acids, their derivatives and even other organic and inorganic substances can be remediated from the environment (Finstein et al., 1986). Compost pro...
Phytoextraction is the uptake and storage of pollutants in the plants stem or leaves. Some plants, called hyperaccumulators, draw pollutants through the roots. After the pollutants accumulate in the stem and leaves the plants are harvested. Then plants can be either burned or sold. Even if the plants cannot be used, incineration and disposal of the plants is still cheaper than traditional remediation methods. As a comparison, it is estimated a site containing 5000 tons of contaminated soil will produce only 20-30 tons of ash (Black, 1995). This method is particularly useful when remediating metals. Some metals are also being recycled from the ash.
The global population in the year 2050 is expected to be nine billion and the agricultural demand is expected to double. With the current population already over seven billion people, there are hunger issues all around the world (“New” par. 1). How are we going to deal with food shortages in the future? With less land to work with, strains on the soils, and the lack of water, it is getting harder for the farmers of the world to support our growing population. These complications are making it harder for farmers to produce quality, affordable food. To help the crops grow better, farmers use fertilizers and chemical sprays to enhance growth and control the weeds. Farming in the United States is a relevant business because it supplies people with food, provides people with jobs maintaining the used equipment with the new equipment being much more expensive, and it provides research for more efficient ways on how to feed the world.
This lesson is designed to review and reinforce a few important concepts about plants (e.g. Needs, parts, sequence of planting) and to also guide the students through applying a few scientific inquiry (e.g. Making observations, experimentation, discussion, reflection, reporting results etc.). The students have previously planted corn and bean seeds and today’s lesson has provided the students a chance to see the results of the planted corn and bean seeds. Additionally, seeds have been planted under and growing under the following conditions: without water, and without soil. The students see the results of these seeds planted under these conditions for the past week. Two plants in particular have already been grown their growth has been
People have depended on agriculture for years as the primary source of getting food. We have developed all kinds of ways to manipulate nature so what we can produce higher yield crops, more nutritious crops, bigger crops, crops that withstand cold, and farming equipment that allows us to manufacture these crops with relative ease. Why then are there five billion people being malnourished and forty thousand children dying each day from hunger? It seems as though world hunger is more a result of the lack of distributing the food properly than the lack of quantity. agriculture has turned into a high profit business and biotech companies like Monsanto are constantly trying to come up with better and more efficient ways of farming. Are they doing this to try to solve the world hunger crisis, or merely to make a profit?
The final phase of research (2009-2012) will look at how phytoremediation plants might be able to produce materials such as precious wood, fibres, chemicals, essential oils, dyes, gums, and recoverable minerals and metals for secondary industries, and thus help local communities.
