Emmer wheat or hulled wheat is a type of awned wheat. Emmer is a tetraploid. The domesticated types are Triticum turgidum subsp. dicoccum and T. t. conv. durum. The wild plant is called T. t. subsp. dicoccoides. The principal difference between the wild and the domestic forms is that the ripened seed head of the wild plant shatters and scatters the seed onto the ground, while in the domesticated emmer, the seed head remains intact, thus making it easier for people to harvest the grain.
Yemenite Hebrew, also referred to as Temani Hebrew, is the pronunciation system for Hebrew traditionally used by Yemenite Jews. Yemenite Hebrew has been studied by language scholars, many of whom believe it retains older phonetic and grammatical features lost elsewhere. Yemenite speakers of Hebrew have garnered considerable praise from language purists because of their use of grammatical features from classical Hebrew.
Oryzopsis is a genus of Chinese and North American plants in the grass family. Species from this genus are commonly called ricegrass.
Foxtail millet, scientific name Setaria italica, is an annual grass grown for human food. It is the second-most widely planted species of millet, and the most grown millet species in Asia. The oldest evidence of foxtail millet cultivation was found along the ancient course of the Yellow River in Cishan, China, carbon dated to be from around 8,000 years before present. Foxtail millet has also been grown in India since antiquity.
Echinochloa crus-galli is a type of wild grass originating from tropical Asia that was formerly classified as a type of panicum grass. It is commonly known as cockspur, barnyard millet, Japanese millet, water grass, common barnyard grass, or simply "barnyard grass". This plant can grow to 1.5 m in height and has long, flat leaves which are often purplish at the base. Most stems are upright, but some will spread out over the ground. Stems are flattened at the base. The seed heads are a distinctive feature, often purplish, with large millet-like seeds in crowded spikelets.
Bar Kappara was a Jewish scholar of the late second and early third century CE. He was active in Caesarea Maritima, the capital of the Roman province of Syria Palaestina, from around 180 to 220 CE. His name, meaning "Son of Qappara", was taken from his father, Eleazar ha-Kappar. He was one of the students of Judah ha-Nasi and a first-generation amora.
Ohalo II is an archaeological site in Northern Israel, near Kinneret, on the southwest shore of the Sea of Galilee. It is one of the best preserved hunter-gatherer archaeological sites of the Last Glacial Maximum, radiocarbon dated to around 23,000 BP (calibrated). It is at the junction of the Upper Paleolithic and the Epipaleolithic, and has been attributed to both periods. The site is significant for two findings which are the world's oldest: the earliest brushwood dwellings and evidence for the earliest small-scale plant cultivation, some 11,000 years before the onset of agriculture. The numerous fruit and cereal grain remains preserved in anaerobic conditions under silt and water are also exceedingly rare due to their general quick decomposition.
Kil'ayim is the fourth tractate of Seder Zeraim of the Mishnah, dealing with several biblical prohibitions of mixed species, namely, planting certain mixtures of seeds, grafting different species of trees together, growing plants other than grapevines in vineyards, crossbreeding animals, working a team of different kinds of animals together, and mixing wool and linen in garments.
Shevi'it is the fifth tractate of Seder Zeraim of the Mishnah, dealing with the laws of leaving the fields of the Land of Israel to lie fallow every seventh year; the laws concerning which produce may, or may not be eaten during the Sabbatical year; and the cancellation of debts and the rabbinical ordinance established to allow a creditor to reclaim a debt after the Sabbatical year (Prozbul).
In Judaism, the five species of grain refer to five varieties of grain which have special status for a number of rituals. These species are commonly considered to be wheat, barley, oats, rye and spelt. However, some of these identifications are disputed.
Setaria is a widespread genus of plants in the grass family. The name is derived from the Latin word seta, meaning "bristle" or "hair", which refers to the bristly spikelets.
The House of Hillel and House of Shammai were, among Jewish scholars, two schools of thought during the period of tannaim, named after the sages Hillel and Shammai who founded them. These two schools had vigorous debates on matters of ritual practice, ethics, and theology which were critical for the shaping of the Oral Law and Judaism as it is today.
Barley, a member of the grass family, is a major cereal grain grown in temperate climates globally. It was one of the first cultivated grains; it was domesticated in the Fertile Crescent around 9000 BC, giving it nonshattering spikelets and making it much easier to harvest. Its use then spread throughout Eurasia by 2000 BC. Barley prefers relatively low temperatures and well-drained soil to grow. It is relatively tolerant of drought and soil salinity but is less winter-hardy than wheat or rye.
Panicum sumatrense, known as little millet, is a species of millet in the family Poaceae.
Kil'ayim are the prohibitions in Jewish law which proscribe the planting of certain mixtures of seeds, grafting, the mixing of plants in vineyards, the crossbreeding of animals, the formation of a team in which different kinds of animals work together, and the mixing of wool with linen in garments.
Nathan ben Abraham, known also by the epithet President of the Academy in the Land of Israel, was an 11th-century rabbi and exegete of the Mishnah who lived in Ramla, in the Jund Filastin district of the Fatimid Caliphate. He was the author of the first known commentary covering the entire Mishnah.
Corpse uncleanness is a state of ritual uncleanness described in Jewish halachic law. It is the highest grade of uncleanness, or defilement, and is contracted by having either directly or indirectly touched, carried or shifted a dead human body, or after having entered a roofed house or chamber where the corpse of a Jew is lying.
Linum strictum, commonly known as rigid flax, upright flax, and upright yellow flax, is a species of flax with a rigid stem, from whence it derives its taxonomic name, growing to a height of 10–45 cm. The plant is endemic to the Mediterranean region. It features highly in classical Hebrew and Greek literature, owing principally to its cultivation for its plant fiber, linen, but also for its edible seeds and culinary foliage.
Mordechai E. Kislev is an Israeli emeritus professor in the Mina and Everard Goodman Faculty of Life Sciences at Bar-Ilan University, specializing in archaeological botany. Some of his prominent research focuses on prehistoric early agriculture and archaeological entomology. Other works explore the ancient landscape of the Land of Israel, as well as Torah and Science issues.
Urochloa ramosa, the browntop millet or Dixie signalgrass, is an annual, millet grass belonging to the grass family (Poaceae). The native range of Urochloa ramosa is from Africa to tropical and subtropical Asia.
