Abstract
The present investigation was carried out to study the effect of micronutrients on
growth, yield and quality in papaya cv. Red lady at College of Horticulture, Bagalkot
during 2016-2017.
In the experiment on effect of soil application of Zinc, Boron and Iron,
T12[treatment having Zn (10g) + B (5g) + Fe (10g)] has recorded maximum plant
growth (1.42m plant height, 34.37 cm stem girth, 41.34 leaves per plant), reproductive
parameters (49.50 flowers and 28.67 fruits per plant) and fruit yield (43.99 kg/plant).
The maximum values of qualitative parameters in respect of total soluble solids
(12.98°Brix), ascorbic acid (23.64 mg/100g pulp) and maximum fruit parameter (1.54
kg weight of fruit) were also obtained with the same treatment.
Whereas in the experiment on finding out suitable period of soil application of
micronutrient mixture, T9 [treatment having Zn (10g), B (3g) and Fe (10g) at 1, 3, 5 and
7 months after transplanting) has recorded maximum plant growth (1.30m plant height,
36.00 cm stem girth, 48.56 leaves per plant), reproductive parameters (50.11 flowers
and 28.33 fruits per plant) and fruit yield (43.54 kg/plant). The maximum values of
qualitative parameters in respect of total soluble solids (11.50°Brix), ascorbic acid
(23.03 mg/100g pulp) and maximum fruit parameters (1.54 kg weight of fruit) were also
obtained with the same treatment.
In the experiment on effect of time and concentration of foliar application of
fruit special, T9 (5g/l at 30 days interval) has recorded maximum plant growth (1.65 m
plant height, 35.75 cm stem girth, 43.83 leaves per plant), reproductive parameters
(52.50 flowers and 31.00 fruits per plant) and fruit yield (46.10 kg/plant). The
maximum values of qualitative parameters in respect of total soluble solids
(11.78°Brix), ascorbic acid (25.45 mg/100g pulp) and maximum fruit parameters (1.52
kg weight of fruit) were also obtained with the same treatment.
