For broadcast seeded rice, recent work conducted by the Rice Research and Training Center (RRTC) indicated that the most effective treatment is the split application of fertilizer nitrogen in three equal doses: one third applied before planting, incorporated in dry soil; one third at the mid tillering stage and one third at panicle initiation. The high efficacy offers considerable reduction of the application rate (as compared to soil application), without compromising the results, thus a marked saving on the fertilizer is achieved and a minimal environmental foot-print takes place. plants or seeds (about 5 cm apart). fertilizer materials, Basic Agriculture Study is a participant in the Amazon Services LLC Associates Program, https://agriculturistmusa.com/methods-of-fertilizer-application/, Maturity, Maturity indices, Types of maturity and Determination of maturity, Objectives, Scope, Concept and Causes of Plant Diseases, Differentiate between physiological maturity and horticultural maturity, Methods of Fertilizer Application.
