Post emergence herbicides

An herbicide applied after the crop and or weeds have emerged from the soil.

Moisture stress

Occurs when the plant suffers from a lack of water to support good growth and development.

Jul

Post emergence

Factors that are relevant after the emergence of the seedling or weed from the soil.

Moisture meter

Keeping track of grain moisture content during drying is crucial to properly dry grain; that is, to avoid over drying or incomplete drying. Over drying leads to monetary loss when selling the grain and to reduced milling yields due to cracking of the brittle dry grains. Incomplete drying causes qualitative and quantitative losses from fungal growth, insect activity and respiration.

Positional cloning

Experimental approach used to locate and isolate gene sequences for which the gene product is not known. Instead the phenotype is mapped and large fragments are isolated in the region of informative molecular markers known to segregate closely with the gene of interest.

Jul

Moisture Deficit Index (MDI)

The MDI is usually determined on the basis of annual precipitation and annual potential evapotranspiration. This does not reflect the true nature of MDI for the purpose of crop production, although it does give information regarding the degree of aridity. Since this index sometimes is used as a criterion for crop planning, it would appear more appropriate for it to be based on precipitation and PET during the crop growth period.

Pore space

The space in soils not occupied by solid particles.

Jul

Moisture content

The amount of water measured in the soil or plant. Expressed as percentage moisture based on total fresh weight of the substance.

Jul

Modulated lamp system

A system that provides a realistic simulation of anticipated ozone depletion. It modulates lamp output in accordance with actual levels of incoming solar uv radiation.

11
Jul

Modifying gene

A gene that alters the expression of another gene which is non-allelic. The effect of the modifying gene (modifier) is relatively small compared to that of the non-allelic gene being affected.

Jul

Modern varieties (cultivars)

Dwarf, semidwarf, stiff-stemmed, high tillering, nitrogen-responsive, photoperiod-insensitive, high-yielding varieties. Their characteristics are different from those of traditional varieties.

11
Jul

Moderate resistance

Intermediate levels of resistance, between resistant and susceptible.

11
Jul

Model

Mathematical use of data to project experimental results. A small imitation of the real thing; a system of postulates, data, and inferences presented as a mathematical description of an entity or state of affairs.

11
Jul

Mode of action

The way in which a pesticide acts. For example, organophosphorous compounds disrupt the nerve impulses in insects.

11
Jul

Mode

The most frequent values considered from observation or data.

11
Jul

Mixed row cropping

Growing two or more crops simultaneously intermingled within a distinct row arrangement.

11
Jul

Mixed intercropping

Simultaneously growing two or more crops intermingled in the same plot, with no distinct row arrangement.

11
Jul

Mixed fertilizers

Fertilizers containing two or more of the major fertilizer elements.

11
Jul

Mixed farming

Raising of crops, animals (livestock), and/or trees simultaneously in the same piece of land.

11
Jul

Mixed cropping

A cropping system that uses more than one type of crop, growing simultaneously, on the same piece of land at the same time.
