The oscar (Astronotus ocellatus) is a species of fish from the cichlid family known under a variety of common names, including tiger oscar, velvet cichlid, and marble cichlid. [2] In tropical South America, where the species naturally resides, A. ocellatus specimens are often found for sale as a food fish in the local markets.
Irrigation is the process of artificially applying water to soil to allow plant growth. This term is preferably used when large amounts of water is applied to dry, arid regions in order to facilitate plant growth. The process of irrigation not only increases the growth rate of the plant but also increases the yield amount.
Agronomic studies often focus on the above-ground part of plant biomass, and consider crop growth rates rather than individual plant growth rates. Nonetheless there is a strong corollary between the two approaches. More specifically, the ULR as discussed above shows up in crop growth analysis as well, as: = . = .
The plant becomes rather low maintenance after planting. [10] The plant requires to be weeded 3-4 times in the first year and annually in the following years. [11] Manure can be applied to the soil during the second weeding to provide the best yields in the first year. [11] The pits need to be fenced off to protect the plants from grazing. [11]
Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite .
Map of average growing season length from "Geography of Ohio," 1923. A season is a division of the year marked by changes in weather, ecology, and the amount of daylight. The growing season is that portion of the year in which local conditions (i.e. rainfall, temperature, daylight) permit normal plant growth.
Tigridia / t aɪ ˈ ɡ r ɪ d i ə /, [2] is a genus of bulbous or cormous flowering plants belonging to the family Iridaceae.With common names including peacock flowers, [3] tiger-flowers or shell flowers, they have large showy flowers; and one species, Tigridia pavonia, is often cultivated for this.
In the regions where tiger bush is present, plant growth is water-limited - the shortage of rainfall prevents vegetation from covering the entire landscape. Instead, trees and shrubs are able to establish by either tapping soil moisture reserves laterally or by sending roots to deeper, wetter soil depths.
