Nitrogen Management in Crops

These flashcards cover key concepts and terms related to nitrogen management in crops, focusing on the importance of nitrogen, its uptake, and the physiological differences among plant species.

Nitrogen (N)

An essential nutrient for plants, critical for growth and photosynthesis.

Photosynthesis

The process by which plants use light energy to convert CO2 and water into glucose and oxygen, requiring nitrogen.

Critical nitrogen dilution curve

A model used to determine the optimal nitrogen status of a crop during its growth stages.

N uptake

The process through which plants absorb nitrogen from the soil.

Grain filling

The process during which cereal crops accumulate nitrogen needed for seed development.

Remobilization of nitrogen

The process of nutrient redistribution within the plant during different growth stages, particularly from anthesis to maturity.

Rooting depth index

A measure used to assess the penetration depth of roots which correlates with nutrient uptake capabilities.

Genotypes

The genetic constitution of an organism, which can affect its nitrogen demand and uptake efficiency.

Biomass

The total mass of living matter within a certain area, affected by nitrogen availability and uptake.

Cereal crop development

The growth stages of cereal plants, during which nitrogen plays various roles.
