Nitrogen deficiency (N)

The most frequently observed symptom of nitrogen deficiency is a reduced leaf size together with large-scale yellowing, which is most pronounced close to leaf veins. These symptoms particularly occur on shoot leaves with fruit. These fruit will be diminished in size and their skin will be thinner.


Nitrogen deficiency may be addressed by applying readily absorbable nitrogen (in the form of nitrate) directly on the ground. Another option is foliar application, or, in serious cases, fertigation. This method will allow plants to immediately absorb the nutrient.
