dc.description.abstractThe presentt iinvesttiigattiion was carriied outt on wheatt duriing rabii,, 2017-18 tto sttudy tthe effectt of prescriipttiion based ferttiilliizer applliicattiion on diifferentt fracttiions of ziinc iin a llong tterm experiimentt iiniittiiatted duriing khariiff,, 2007 att tthe experiimenttall farm of tthe Departtmentt of Soiill Sciience CSK HPKV,, Pallampur.. The experiimentt was llaiid outt iin a randomiized bllock desiign consiisttiing of eiightt ttreattmentts.. The soiill of experiimenttall fiielld was siilltty cllay lloam iin ttextture,, pH 5..2,, organiic carbon 7..2 g kg--1 and avaiillablle N,, P and K sttattus was 236,, 41 and 272 kg ha--1,, respecttiivelly.. The soiill samplles from 0- 0..15 m soiill deptth were collllectted before and aftter harvestt of wheatt.. The soiill samplles were anallyzed for physiicall,, chemiicall,, biiollogiicall properttiies and diifferentt fracttiions of ziinc iin soiill att harvestt of tthe crop.. Graiin and sttraw samplles were collllectted from each pllott and anallyzed for N,, P,, K,, Fe,, Mn,, Zn,, Cu conttentt and ttheiir upttake by graiin and sttraw of wheatt.. The sttudy revealled tthatt tthe ttargett yiielld of 35 q ha--1 wiitth FYM resulltted iin hiighestt wheatt graiin yiielld (34..9 q ha--1) and sttraw yiielld (58..4 q ha--1).. In prescriipttiion based ferttiilliizer applliicattiion for ttargetted yiielld of 25 q ha--1 wiitth and wiitthoutt FYM a siigniifiicantt hiigher graiin and sttraw yiielld was recorded as compared tto ttreattmentts where ferttiilliizer was applliied as per soiill ttestt based and generall recommended dose.. A siigniifiicantt iimprovementt iin nuttriientts upttake was recorded iin ttargett yiielld ttreattmentts wiitth FYM as compared tto wiitthoutt FYM ttreattmentts.. The DTPA-exttracttablle miicronuttriientt cattiions,, organiic carbon,, and miicrobiiall biiomass carbon were hiigher iin 25 and 35 q ha--1 ttargett yiielld ttreattmentts wiitth FYM iin compariison tto restt of tthe ttreattmentts.. The conttiinuous use of chemiicall ferttiilliizers broughtt outt marked depllettiion iin tthe poolls of Zn,, whiille iinttegratted applliicattiion of FYM and chemiicall ferttiilliizers recorded rellattiivelly hiigher conttentt of poolls of Zn over chemiicall ferttiilliizer applliicattiion.. Resiiduall Zn was tthe mostt domiinantt fracttiion of ziinc conttriibuttiing aboutt 49..94 per centt and non-speciifiicalllly adsorbed exchangeablle ziinc was tthe lleastt domiinantt fracttiion of ziinc conttriibuttiing aboutt 0..43 per centt tto ttottall ziinc..en_US
