Abstract

Kinnow is the most preferred cultivar in Punjab due to its wider adaptability, yield and higher economic returns. However, excessive fruit drop is becoming a major cause for achieving low fruit yield. This could be attributed mainly to the lack of appropriate nutrient management for Kinnow orchards. The soil and leaf chemical analysis showed severe deficiency of Zn and B in Kinnow. Therefore the present study was carried out in the farmer’s field at Abohar, Punjab with an objective to examine the influence of micronutrients on the growth and quality of Kinnow and in order to frame the appropriate dose. The experiment was laid out in randomized block design with ten treatments and three replications. Results show that in basal dose, treatment of Zn and B (250 gm/plant) gives fruit weight (198.78 g), number of fruits (269.66), weight of fruit/plant (58.00 kg) and vitamin C (20.83%), fruit drop (33.21%) and in foliar dose, treatment of Zn (3gm) and B (2gm) gives plant height (25.40cm), number of fruits (298), weight of fruit/plant (60.00 kg) and vitamin C (17.50%), while combination treatment of basal + foliar of Zinc (250+3gm) and boron(250+2gm) significantly improved the plant height (29.46cm), fruit length (4.95cm), width (5.61cm) and vitamin C (24.16%) with lowest fruit drop of 28.48% was obtained.
