Manganese

Manganese Deficiency Symptoms Deficiency symptoms appear in the form of interveinal chlorotic mottling of apical part of the second set of leaves. The entire lamina become severely mottled and the interveinal chlorotic areas develop light brown irregular necrotic patches. These patches, which are initially more conspicuous near the leaf tips, later spread to the entire lamina, which eventually turn severely necrotic. Symptoms gradually spread from the middle to the young and old leaves. Correction Measure Foliar spray of 0.2% MnSO 4 (2g/lit)solution 2-3 times at weekly intervals, after the appearance of deficiency symptoms. Mix 10 kg MnSO 4 /ha with 45 kg of soil and broadcast evenly in the beds after sowing.
