Increasingly, besides food for humans and [[fodder|animal feeds]], agriculture produces goods such as cut flowers, ornamental and [[Nursery (horticulture)|nursery]] plants, [[fertilizer]]s, [[animal hides]], [[leather]], industrial chemicals ([[starch]], [[ethanol]], and [[plastic]]s), [[fiber]]s ([[cotton]], [[wool]], [[cannabis|hemp]], and [[flax]]), fuels ([[methane]], [[biodiesel]], [[biomass]]), and both legal and illegal [[drugs]] ([[biopharmaceutical]]s, [[tobacco]], [[marijuana]], [[opium]], [[cocaine]]). [[GMO|Genetically engineered]] plants and animals produce specialty drugs.
In the Western world, use of improved [[genetics]], better management of soil nutrients, and improved [[weed control]] have greatly increased yields per unit area.
Modern agriculture depends heavily on engineering and technology and on the biological and physical sciences. [[Irrigation]], [[drainage]], [[conservation]], and sanitary engineering—each of which is important in successful farming—are some of the fields requiring the specialized knowledge of agricultural engineers.
Baris ka-23:
Animal husbandry means breeding and raising animals for meat or to harvest animal products (like milk, eggs, or wool) on a continual basis.
In recent years, some aspects of industrial [[intensive agriculture]] have been the subject of increasing discussion.
[[Soil]] [[conservation]] and nutrient management have been important concerns since the [[1950s]], with the best farmers taking a [[stewardship]] role with the land they operate.
Increasing consumer awareness of agricultural issues has led to the rise of

After [[1492]], the world's agricultural patterns were shuffled in the widespread exchange of plants and animals known as the [[Columbian Exchange]].

=== World production of major crops in 2002 ===
In millions of metric tons, based on [[USDA]] estimates:

:[[Cotton]] 96.5
''Paddy rice'' is rice in its as-harvested state.
=== Crop improvement ===
[[
Domestication of plants is done in order to increase yield, disease resistance, drought tolerance, ease of harvest, and to improve the taste and [[nutrition]]al value and many other characteristics.
For example, average yields of corn ([[maize]]) in the USA have increased from around 2.5 tons per hectare (40 bushels per acre) in [[1900]] to about 9.4 t/ha (150 bushels per acre) in [[2001]], primarily due to improvements in genetics. Similarly, worldwide average wheat yields have increased from less than 1 t/ha
[Conversion note: 1 bushel (q) of wheat = 60 pounds (lb)
Very recently, [[genetic engineering]] has begun to be employed in some parts of the world to speed up the selection and breeding process.
There are specialty producers who raise less common types of livestock or plants.
