Abstract
The investigation was conducted in the Main Horticultural Research and
Extension Center, University of Horticultural Sciences, Bagalkot during the year 2020
to 2021 with an objective to study the influence of foliar application of nutrients on
growth, flowering, yield, quality and shelf life of mango cv. Kesar. The experiment
consisted of five treatments with four replications laid out in Randomized Block Design
and spray was taken during November (before flowering), pea nut stage and marble
stage. Among the different treatments, foliar application of potassium nitrate @ 2 per
cent during November (before flowering) + Arka mango special @ 0.5 per cent at pea
nut and marble stage has recorded maximum panicle length (34.35 cm), panicle width
(28.50 cm), fruit set (0.87 %), fruit weight (298.50 g), number of fruits harvested per
tree (277.41), yield (82.86 kg/tree and 8.66 t/ha) compared to control which was
recorded minimum fruit yield (50.09 kg/tree and5.73 t/ha).
The fruit quality and biochemical parameters of mango viz., high total sugars
(13.22 %), TSS (20.87 0B), ascorbic acid content (33.75 mg/100 g pulp), carotenoid
content (9.33 mg/100 g pulp), phenolic content (44.75 mg CE/100 g pulp) and
minimum titratable acidity (0.19 %) were also recorded high in foliar application of
potassium nitrate @ 2 per cent during November (before flowering) + Arka mango
special @ 0.5 per cent at pea nut and marble stage and maximum days of shelf life
(14.60), fruit firmness (2.05 kg/cm2
) was recorded in T5 (calcium nitrate (Ca (NO3)2) @
2.0 per cent during November (before flowering) + sulphate of potash (SOP) @ 2.0 per
cent at pea nut and marble stage).
The highest total income (Rs. 74574.00), net income (Rs. 51485.50) and benefit
cost ratio (2.22:1) was recorded in the treatment potassium nitrate @ 2 per cent during
November (before flowering) + Arka mango special @ 0.5 per cent at pea nut and
marble stage. Among the different treatments, the trees treated with potassium nitrate @
2 per cent during November (before flowering) + Arka mango special @ 0.5 per cent at
pea nut and marble stage influenced the improved flowering, increased yield, better
quality and benefit cost ratio as compared to other treatments.
