Studies on the Influence of Micronutrient on Growth, Yield and Quality of Kinnow Mandarin

An experiment was carried out at the farmer orchard to study the effect of micronutrients on four years old Kinnow mandarin trees. Different treatments involved application of micronutrients. Among the sprays of different micronutrients, the trees receiving four sprays of ZnSo4 at 0.5% with monthly interval starting from first spray at flowering stage has recorded significantly higher tree height, tree spread (north-south and east-west) direction at 90th days after four sprays, increased number of fruits per tree (519.67), fruit yield per tree (61.78 kg) and fruit yield per hectare (20.57 tons) over control and was par with other treatments. Highest ascorbic acid (80.63 mg/100 g pulp) and phenols were recorded (247.50 mg/100 g pulp) over control and was on par with other treatment. Foliar application of FeSO4 at 0.5% incareased TSS (9.97 oB), reducing sugar was (3.59%) and the total sugar (9.27%) when the same number of sprays were applied.
