EFFECT OF CPPU AND POTASSIUM ON YIELD AND FRUIT MATURITY IN LOW CHILL PLUM CV. SATLUJ PURPLES. Sharma, H. Singh and S.K. Jawandha
Foliar sprays of CPPU (2.5 ppm and 5.0 ppm) and potassium salts (KNO3 and K2SO4) at 1 per cent and 2 percent were done at 7 DAFB and 14 DAFB on 12 year old plum plants. Minimum fruit drop and maximum fruit retention was recorded under CPPU treatments followed by KNO3 and K2SO4. All the CPPU treatments significantly increased fruit yield but delayed fruit maturity whereas KNO3 treatments advanced fruit maturity in plum cv. Satluj Purple.
