Growing only in the presence of molecular oxygen. Having molecular oxygen as part of the environment.

Aerobic digestion

The partial biological decomposition of suspended organic matter in waste water or sewage under aerated conditions.

Aerobic Rice

Aerobic rice is a production system in which especially developed “aerobic rice” varieties are grown in well-drained, non-puddled, and non-saturated soils. With appropriate management, the system aims for yields of at least 4-6 tons per hectare. Compared with flooded lowland rice, aerobic rice requires 30-50 % less water. Aerobic rice can be found, or can be a suitable technology, in the following areas:


A technique in growing plants wherein the plants derive their nutrients and water from a mist of air and aqueous solution that come in contact with the roots.


The inactive or dormant state of a larva during summer.


A toxin produced by species of the fungus Aspergillus, especially Aspergillus flavus, which grows on seeds and nuts and affects stored grain.

AFLP (Amplification Fragment Length Polymorphism)

A variant DNA amplification product of different size produced by DAF, PCR, or RAPD technique.

African rice

Oryza glaberrima, commonly known as African rice, is a domesticated rice species, less common and less well known than Asian rice, Oryza sativa. African rice is believed to have been domesticated 2,000-3,000 years ago in the inland delta of the upper Niger river, ie what is now Mali. Its wild ancestor, which still grows wild in Africa, is Oryza barthii.


Mucilage derived from seaweed. It forms a gel with water. It is used to solidify culture media on which microorganisms are grown.

Aged rice

Rice that is kept at least 4 months after harvest. Expands more on cooking and less sticky than cooked, freshly harvested rice.


An agitator is a device or mechanism to put something into motion by shaking or stirring.

Agrarian system

A historically constituted and durable mode of exploitation of the environment; a technical system adapted to the bioclimatic conditions of a given area.

Agricultural lime

A soil amendment consisting principally of calcium carbonate but including magnesium carbonate and perhaps other material. This is used to provide calcium and magnesium as elements for the growth of plants and to neutralize soil acidity.

Agricultural production system

The whole structured set of plants, animals, and activities selected by a farmer for his production unit to achieve its goals.


The practice of domestication, culturing and farming of plants, animals and microbes for food, fodder, fibre and aethetics.


The aspects of biodiversity that affect agriculture and food production, including within species, species and ecosystem diversity.


Agrochemical or agrichemical is a term for the various chemical products used in agriculture. In most cases, agrichemical refers to the broad range of pesticides, including insecticides, herbicides, and fungicides. It may also include synthetic fertilizers, hormones and other chemical growth agents, and concentrated stores of raw animal manure.


Relating to the relationship between crop adaptation and climate.

Agro-climatic conditions

Relating to the relationship between crop adaptation and climate. The climatic, edaphic (determined by soil) and socio-economic diversity of the indian crop-production scene is dotted with many cropping patterns.

Agro-climatic zones

Geographical mapping units based


The study of climate in relation to agriculture.

Agro-ecological zones

Geographical mapping units based on climatic conditions and land forms that determine relatively homogeneous crop growing environments.


The economics of agriculture.


A community of biotic and Abiotic components of environment in a crop-producing area.


Agroinfection, an alternative route for viral infection of plants by using the ti plasmid.


The study of the relationship between conditions in the lowest layer of the atmosphere and those on the surface of the earth, as this affects agriculture.
