Abstract About 56 percent of the soils in high altitude areas of Srikakulam and Vizianagaram districts are acidic and 49 percent of soils in these districts are deficient in molybdenum. An experiment was conducted at two different sites for two years in a molybdenum deficient soil (0.29mg kg -1& 0.15 ) having pH (5.9 & 5.4) and electrical conductivity (0.15 dS m-1 & 0.19 dS m-1) at Regional Agricultural Research Station, Chintapally, located in a high altitude zone of Andhra Pradesh in India. The treatments consisted of soil application of 0.25, 0.5, 0.75, 1.0 kg ha-1 sodium molybdate to maize; soil application of 0.25 kg ha-1 sodium molybdate to both maize and niger; soil application of 0. 5 kg ha-1 sodium molybdate to maize + 0.25 kg ha -1 sodium molybdate to Niger; soil application of 0.25 kg ha-1 sodium molybdate to maize + 0.5 kg ha-1 sodium molybdate to niger; seed treatment with 0.5 g kg-1 seed to both maize and niger; foliar spray of 0.1% sodium molybdate to maize and niger;75% lime requirement + soil application of 0.25 kg sodium molybdate ha-1 to maize and niger; 75% lime requirement + foliar spray of 0.1% sodium molybdate to maize and niger; lime requirement; FYM @ 5t ha-1; control (Recommended dose of NPK only). Soil application of molybdenum as sodium molybdate (0.50, 0.75 and 1.0 kg ha-1) significantly increased the maize cob yield over control. Residual effect of molybdenum was significant on niger at soil application of 0.75 and 1.0 kg sodium molybdate ha-1 which was applied initially to maize crop. Significant increase in molybdenum uptake was recorded due to increase in levels of molybdenum. Soil application of 0.5 kg molybdenum ha-1 for the direct crop of maize and 0.75 kg molybdenum ha-1 applied to maize crop can meet the needs of the 2nd crop that is niger in the maize-niger cropping system grown on acid soils of high altitude zone of Andhra Pradesh in India for getting the highest yields
