?IMPROVING PHOSPHORUS FERTILIZER USE EFFICIENCY IN WHEAT THROUGH METHOD OF ApPLICATION

Abstract

The recommended method of "broadcasting and incorporation" of solid P fertilizer before sowing was compared and
evaluated against "top dressing" ofP after plantemergance and as "solution application" along with irrigation water (termed
fertigation) by growing wheat in pot and field experiments. The lower Prate applied by fertigation at first irrigation resulted
in equivalent wheat yield and 25-30% higher P fertilizer efficiency compared to higher rate applied broadcast and
incorporated at sowing, indicating the possibility of substantial saving in P fertilizer input.
