Abstract
Two field experiments were conducted on Mn-deficient soils to evaluate the efficiency of rates, methods and time of MnSO4.H2 O application for wheat. Manganese sulphate was broadcast and mixed in soils at the rate of 5 to 50kg Mn ha−1 before seeding and 10 to 40 kg Mn ha−1 as top dress at 28 days — just before first irrigation. Three sprays of 1% MnSO4·H2O unneutralised solutions were applied, the first at 26 days — 2 days before first irrigation and the others afterward at weekly intervals. Both the methods caused a significant and marked increase in grain yield. Three foliar sprays were as effective as soil applications of 20 to 40 Kg Mn ha−1 before seeding. The difference in grain yield resulting from soil applications of Mn before seeding and applications at the first irrigation was not significant. The DTPA-Mn status of 20 fields, selected on the basis of varying degree of Mn deficiency, was related to grain yield (r = 0.77**). Also grain yield of all the experiments had a significant correlation with Mn content of grain (r = 0.55** to 0.82**) and straw (r = 0.77** to 0.82**). The critical limits calculated by statistical method were 1.25, 2.18 and 3.5 mg Mn kg−1 soil for severe deficiency, deficiency and latent deficiency respectively for wheat.
