Aman ullah Salarzai

Abstract


In a field experiment the response of canola to different levels of NPK (60-0-0,60-30-0,60-30-75, 90-30-75,90-60-100,120-60-75,120-60-100 and 150-90-100kg ha¯¹) was studied at the Agronomic Research Area, Sindh Agriculture University, Tando jam,Increasing level of N,P and K significantly increased all the yield components and seed protein contents while decreased that seed oil contents in Canola. Maximum seed yield (2670.78kg ha¯¹) was recorded when canola crop was fertilized at the rate of 90-60-75 kg NPK ha¯¹.
