Andalusi Agricultural Corpus
The Andalusi agricultural corpus are texts of agronomic knowledge and sources for the history of agriculture in the Andalusi Iberian Peninsula. Agronomic advancement had deteriorated under Visigothic rule, but there are eight known agricultural treatises dating from the late 10th century to the mid 14th century, contributing to the Arab Agricultural Revolution. The Andalusi treatises follow the same pattern as Latin agronomic texts: a discussion of soil, water and manure followed by crop science, and sometimes notes on animal husbandry. Six of these are written between the 11th and 13th centuries. The authors of this body of texts are Ibn al-Wafid, Ibn Hajjaj, Ibn Bassal, Abū l-Khayr, Ibn al-'Awwam, Al-Tighnari and Ibn Luyun. Background Muslims from North Africa crossed the Strait of Gibraltar in 711 and established the Caliphate of Córdoba in the southern part of the Iberian peninsula, which they called Al-Andalus. During their long reign of prosperity, the Muslims created a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agronomic
Agricultural economics is an applied field of economics concerned with the application of economic theory in optimizing the production and distribution of food and fiber products. Agricultural economics began as a branch of economics that specifically dealt with land usage. It focused on maximizing the crop yield while maintaining a good soil ecosystem. Throughout the 20th century the discipline expanded and the current scope of the discipline is much broader. Agricultural economics today includes a variety of applied areas, having considerable overlap with conventional economics.Daniel A. Sumner, Julian M. Alson, and Joseph W. Glauber (2010). "Evolution of the Economics of Agricultural Policy", ''American Journal of Agricultural Economics'', v. 92, pp. 403-423. Agricultural economists have made substantial contributions to research in economics, econometrics, development economics, and environmental economics.

Caliphate Of Córdoba
The Caliphate of Córdoba ( ar, خلافة قرطبة; transliterated ''Khilāfat Qurṭuba''), also known as the Cordoban Caliphate was an Islamic state ruled by the Umayyad dynasty from 929 to 1031. Its territory comprised Iberia and parts of North Africa, with its capital in Córdoba. It succeeded the Emirate of Córdoba upon the self-proclamation of Umayyad emir Abd ar-Rahman III as caliph in January 929. The period was characterized by an expansion of trade and culture, and saw the construction of masterpieces of al-Andalus architecture. The caliphate disintegrated in the early 11th century during the Fitna of al-Andalus, a civil war between the descendants of caliph Hisham II and the successors of his '' hajib'' (court official), Al-Mansur. In 1031, after years of infighting, the caliphate fractured into a number of independent Muslim '' taifa'' (kingdoms).

Nabatean Agriculture
''The Nabataean Agriculture'' (), also written ''The Nabatean Agriculture'', is a 10th-century text on agronomy by Ibn Wahshiyya (died ), from Qussīn in present-day Iraq. It contains information on plants and agriculture, as well as on magic and astrology. It was frequently cited by later Arabic writers on these topics. ''The Nabataean Agriculture'' was the first book written in Arabic about agriculture, and the most influential. Ibn Wahshiyya claimed that he translated it from a 20,000-year-old Mesopotamian text. Though some doubts remain, modern scholars believe that the work may be translated from a Syriac original of the 5th or 6th century AD. In any case, it is clear that the work is ultimately based on Greek and Latin agricultural writings, heavily supplemented with local material. The work consists of some 1500 manuscript pages, principally concerned with agriculture but also containing lengthy digressions on religion, philosophy, magic, astrology, and folklore. Some of ...

Cultivars
A cultivar is a type of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and when Plant propagation, propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human genetic engineering, manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''#Formal definition, Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phenology
Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonality, seasonal and interannual variations in climate, as well as environmental factor, habitat factors (such as elevation). Examples include the date of emergence of leaves and flowers, the first flight of butterflies, the first appearance of bird migration, migratory birds, the date of leaf colouring and fall in deciduous trees, the dates of egg-laying of birds and amphibia, or the timing of the developmental cycles of temperate-zone honey bee colonies. In the scientific literature on ecology, the term is used more generally to indicate the time frame for any seasonal biological phenomena, including the dates of last appearance (e.g., the seasonal phenology of a species may be from April through September). Because many such phenomena are very sensitive to small variations in climate, especially to temperature, phenological records can be a useful proxy (climate), proxy for ...

Plant Morphology
Phytomorphology is the study of the morphology (biology), physical form and external structure of plants.Raven, P. H., R. F. Evert, & S. E. Eichhorn. ''Biology of Plants'', 7th ed., page 9. (New York: W. H. Freeman, 2005). . This is usually considered distinct from plant anatomy, which is the study of the internal Anatomy, structure of plants, especially at the microscopic level. Plant morphology is useful in the visual identification of plants. Recent studies in molecular biology started to investigate the molecular processes involved in determining the conservation and diversification of plant morphologies. In these studies transcriptome conservation patterns were found to mark crucial ontogenetic transitions during the plant life cycle which may result in evolutionary constraints limiting diversification. Scope Plant morphology "represents a study of the development, form, and structure of plants, and, by implication, an attempt to interpret these on the basis of similarit ...
