Abstract:

Productivity of citrus trees depends on many abiotic and biotic factors, among which the adequate supply of micro nutrients is most important in Kinnow mandarin. Therefore a field trial was conducted to assess the effect of foliar application of different micronutrient concentrations on growth characteristics and shelf life of the Kinnow mandarin under rainfed conditions of Jammu. Experiment comprised of nine to ten year old plants on which different concentrations of micronutrients (Zn, Fe and B) were applied through foliar feeding, individually or in combination. Results revealed that Kinnow mandarin trees sprayed with 0.4% ZnSO4+ 0.6% FeSO4+0.2% H3BO3 recorded maximum increase in plant height (37.33 cm), increase in trunk girth (0.60 mm) and increase in plant spread (NS: 28.43 cm and EW: 29.23 cm). However, the highest increase in tree volume (33.35 m3) in Kinnow mandarin was obtained under treatment 0.4% ZnSO4+0.6% FeSO4+0.4% H3BO3. Lowest per cent physiological weight loss in fruits of Kinnow was recorded as 2.13%, 6.40%, 9.52%, 12.94%, 15.54% and 16.93% during 5th, 10th, 15th, 20th, 25th and 30th day of storage in the fruits treated with 0.4% ZnSO4+ 0.6% FeSO4+0.2% H3BO3.
