All plants and vegetation require certain conditions for their proper growth. Therefore it is necessary to bring the environmental conditions under control in order to make those conditions as close to the ideal as possible. To create an optimal environment the main climatic and environmental parameters such as temperature, humidity, light intensity, ground water etc need to be controlled to cr...

Renewed interest in converting biomass to biofuels such as ethanol, other forms of bioenergy, and bioenergy byproducts or coproducts of commercial value opens opportunities for chemists, including agricultural chemists and related disciplines. Applications include feedstock characterization and quantification of structural changes resulting from genetic modification and of the intermediates for...

Banker plants with Aphidius colemani Viereck were tested in greenhouses in Massachusetts and New York for control of cotton aphid Aphis gossypii Glover, and green peach aphid Myzus persicae (Sulzer) on 2 spring flower crops, pansies ( Viola tricolor hortensis ) and Marguerite daisies ( Argyranthemum hybrid). Banker plants consisted of pots of barley plants infested with the bird cherry-oat aphi...

As early as the 19th century, Justus von Liebig (1803 – 1873) identifi ed the lack of vitality of soils and non-existent vigour of plants as relevant causes of increased infections of crops by fungal diseases. Organic farming requires alternative strategies for combating pests and diseases. Soil-applied sulphate fertilisation proved to signifi cantly reduce infection rate and severity of crops ...

The system proposed in this paper collects ‘Green House Effect’ is the technology to provide plants and trees the required nourishment from the sunlight and to prevent the same from the harmful rays/effects of sunlight. As well as greenhouse environmental information such as temperature, maintaining light intensity as well as fulfilling water requirements etc. Accordingly, monitoring crop itsel...

Higher plants are an integral part of strategies for sustained human presence in space. Space-based greenhouses have the potential to provide closed-loop recycling of oxygen, water and food. Plant monitoring systems with the capacity to remotely observe the condition of crops in real-time within these systems would permit operators to take immediate action to ensure optimum system yield and rel...

Declines in bumble bee species in the past 60 years are well documented in Europe, where they are driven primarily by habitat loss and declines in floral abundance and diversity resulting from agricultural intensification. Impacts of habitat degradation and fragmentation are likely to be compounded by the social nature of bumble bees and their largely monogamous breeding system, which renders t...

In this review an attempt has been made to analyze the results of the studies that explored the changes in the growth and development of plants exposed to continuous light published since the 1930s, including papers that are available in Russian only. Potential benefits of using a 24-h photoperiod for the production of greenhouse crops, transplant production in closed controlled environment sys...
