Total organic carbon is the measure of carbon found in an organic compound and is often used as a non-specific indicator of water quality and also the amount of organic carbon in the soil.
A typical analysis for total carbon measures both the total organic carbon present and the complementing total inorganic carbon.

The spreading or trailing type of Groundnut includes Arachis hypogea subspecies procumbens, long duration of 110 - 120 days, late maturity, high yielding ability, and have dormancy of around 60% - 75%, and low percent of germination. Therefore, spreading varieties of groundnut are preferred in areas receiving late rains in the Kharif season, because of the Dormancy in the seed.

Test weight refers to the average weight of cereal as measured in pounds per bushel. It is an important predictor of milling yield for Rice and flour extraction rate for wheat.
The test weight of Basmati rice is 21 g.

Bunchy top disease in sugarcane is caused by Top shoot borer.
Top shoot borer is a pest that damages the cane crop by making holes in emerging leaves, boreholes at the top of the shoot, and dead heart when formed is reddish brown, appears charred, and cannot be easily pulled out.

2, 4 DB or 4-(2, 4-dichlorophenoxy) butyric acid is a selective systemic phenoxy herbicide used to control many annual and perennial broad leaf weeds.
2, 4 D is 2, 4-Dichlorophenoxyacetic acid is a systemic herbicide that kills most broadleaf weeds by causing uncontrolled growth in the weeds.
2, 4 DB cannot be metabolized into 2, 4 D in legumes. Whereas 2, 4 DB is metabolized to 2, 4 D in sensitive species as it is a herbicide. Some legumes that are sensitive to 2, 4 D are tolerant to 2, 4 DB because they lack the β oxidation activity required to activate it.
