Interveinal chlorosis on YOUNG new leaves — leaf tissue between veins turns bright yellow or white while veins remain distinctly green (network pattern). Severe cases: entire young leaves become pale cream-white. Unlike nitrogen deficiency, old leaves remain green.
Iron unavailability despite iron being present in soil — most common in calcareous (alkaline, pH > 7) soils where iron precipitates. Also caused by waterlogging, excessive phosphorus or manganese, or bicarbonate-rich irrigation water.
Maintain soil pH 5.5-6.5 by applying sulfur or organic matter; avoid waterlogging; use drip irrigation with slightly acidified water; grow iron-efficient crop varieties.
Uniform light green to pale yellow discoloration (chlorosis) starting systematically on older bottom leaves; stunted slow spindly growth.
Sandy leaching soils, heavy prolonged monsoon rains washing away nitrates; insufficient decomposed compost.
Incorporate 15-20 metric tons/hectare well-decomposed farmyard manure (FYM); green manuring with Dhaincha or Sunnhemp.
