Effect of Phosphate Carriers and Doses on Yield of Co. 7 Ragi in Major Soil Groups of South India

Abstract

Kesponse of several crops to added phosphate fertilizers is well known. In South India experiments have generally indicated only marginal responses to applied phosphorus. It is possible that soil levels of phosphorus are adequate in certain of these soils and deficient in others. Effect of phosphate carriers also is likely to be reflected finally in crop yields. Comprehensive data regarding the phosphorus requirements of ragi crop grown in South Indian soils are not available. The present work was accordingly undertaken to supply the information, in relation also to differences in phosphate carriers.
