The chlorophyll content is reduced due to which leaf turn pale yellow the older leaves turn completely yellow and fall because nitrogen is rapidly from older to younger leaves. Some plants get dark green leaves with no clawing. Nitrogen deficiency. Organic N is not available to plants until it has been converted to an inorganic form by soil bacteria. Cause – Nitrogen promotes green, leafy growth and deficiency effects in yellowing and stunted growth. Nitrogen deficiency results in reduced photosynthesis (Woledge and Pearse, 1985; Bowman, 1991), reduced plant growth, and chlorosis (Fernandes and Rossiello, 1995).
