Molybdenum Deficiency in Groundnut

Molybdenum Deficiency Symptoms

The deficiency of molybdenum (Mo) is confined largely to acid soils (below 4.5 pH).
Mo availability increase with the increase in pH. Its deficiency is quite likely in high pH soils (above 8.5 pH) also. In legumes, including groundnut, a shortage of molybdenum affects the nitrogen-fixing activities of soil microorganisms. This results in less availability of nitrogen to the plants. Hence, the symptoms of molybdenum deficiency are similar to those of ordinary nitrogen deficiency. Symptoms of molybdenum deficiency resemble those of nitrogen deficiency, that is, yellowing of leaves, stunted growth, and low yield.
