Onions are an excellent crop for farmers

 The onion plant has a fan of hollow, bluish-green leaves and its bulbs at the base of each stem begin to swell when daylengths are equal. The fleshy modified scale envelopes central buds that grow from the tips in an almost cone shaped manner so as not have too many pointed tops for any animal predator or scavenger like birds who would prefer fewer surfaces on which they can land during their hunt while still being able see through enough gaps between one leaf's overlapping edges after another.

The onion plant has been grown and selectively bred in cultivation for at least 7,000 years. It is a biennial that grows as an annual to heights between 15-45 cm (6 inches). The leaves are yellowish -to bluish green with alternate growth patterns along their surfaces; this vegetable's shape may be mistaken by some people when looking out onto nature because it closely resembles other common plants such like garlic or sunflowers!

The three most common onion varieties are yellow, brown and red/purple. Red onions have a sharp pungent flavor that is used for everyday cooking in Asian cuisine while white onions play an important role in classic Mexican dishes like frijoles refritos (fried bean validity).

Many people enjoy the taste of onions, even if they're not quite mature. You can harvest young plants before bulb formation and use them whole to make spring or scallion-like vegetables! When an onion is harvested after bulbing has begun but hasn't yet matured enough for consumption? It may be called "summer" on account that it's still close in season by comparison with other types which are usually ready first (such as large pearl onions). Additionally there exist breeds & varieties specially bred toward smaller size; these would fall under categories such as boilers/picklers depending upon what purpose one wishes their crop yield serve - though note true "pearls" are distinct from either type.

Onions are a perfect example of how to grow successful vegetables in your home garden. They require fertile soil, well-drained ground and plenty nutrients for optimum growth; luckily these three things can all be found together! Onion plants thrive when given the appropriate environment with high levels or fertility made up by phosphorous which helps maintain sturdy stems/bulbs before they're harvested at their mature size following weeks (or months) worths rainwater along side other necessary components like potassium nitrate(!), calcium phosphate.

World onion production reached 4.5 million tonnes in 2019, with China leading 22% of the world total and Japan coming second at 11%. Malawi produces 9 tons per year while Africa accounts for around 10-15 million tons annually from both South America as well North KO01 Kush. In Europe there are also large quantities produced; up to 3 500 000 TMongs done by Russia (2 millions), Turkey & Egypt each producing about 2 000 TMs yearly.
