Abstract : In a field experiment conducted in Uttaranchal, India, during 2000-01, the effect of zinc (Zn), boron (B) and copper (Cu) on the yield and physicochemical properties of mango fruits cv. Dashehari were investigated. The treatments comprised: (T1) control; (T2) 30 kg Zn/ha; (T3) 20 kg B/ha; (T4) 10 kg Cu/ha; (T5) Zn + B; (T6) Zn + Cu; (T7) B + Cu; and (T8) Zn + B + Cu. The highest yield per tree and per hectare was observed in T8 followed by T5. The highest fruit length and weight were observed in T5 followed by T8 while fruit volume was lowest in T8 during both years. The highest TSS, reducing sugars, non-reducing sugars and total sugar were observed in T5 in 2000, while in 2001, highest TSS, reducing sugar, non-reducing sugar and total sugar were observed in T8. The highest ascorbic acid was also observed in T8. T8 and T5 showed the lowest acidity in the fruit compared to the control during both years.
