Abstract
The present investigation entitled “Effect of different chemicals on yield and
quality of ber cv. Gola” was carried out at Fruit Research Station, Khengarvav, College
of Horticulture, Junagadh Agricultural University, Junagadh during the year 2022-23.
The experiment was carried out in Randomized Block Design with three
replications and 9 treatments comprised of Control (T1), NAA @ 40 ppm (T2), NAA @
60 ppm (T3), KNO3 @ 1.5 % (T4), KNO3 @ 2 % (T5), Borax @ 0.4 % (T6), Borax @
0.6 % (T7), Multi-micronutrient grade- IV @ 1 % (T8) and Multi-micronutrient grade IV @ 2 % (T9). Various chemicals applied by foliar spray on 15th October, 2022 at
flowering stage and second spray was 30 days after first spray.
The result on the effect of different chemicals on physical parameters and yield
and yield attributing parameters indicated that the treatment NAA @ 40 ppm executed
maximum fruit weight (27.83 g), fruit length (3.53 cm), fruit diameter (3.62 cm), fruit
volume (29.31 ml), pulp weight (25.41 g), minimum stone weight (2.19 g) with
maximum pulp: stone ratio (11.62), maximum fruit set (11.65 %), minimum fruit drop
(40.83 %), maximum fruit yield (11.88 kg/tree) and yield (3.29 t/ha).
The quality parameters were also significantly influenced by different
chemicals and the lowest acidity (0.19 %), maximum total soluble solids (19.90 °Brix),
TSS: acid ratio (105.13), ascorbic acid (109.25 mg/100 g), total sugars (10.14 %)
reducing sugars (5.68 %) and shelf life (12.67 days) were recorded in NAA @ 40 ppm.
As far as the economic point of view, maximum net realization (64808 ₹ ha-1
)
along with benefit cost ratio (1.97) was obtained in NAA @ 40 ppm.
The results obtained in the present study demonstrated that the foliar spray of
NAA @ 40 ppm (8.8 ml in 10 litre of water) for two times first spray at flowering stage
and second spray 30 days after first spray resulted in enhanced yield and qualitative
parameters and also gave maximum net realization and BCR in ber cv. Gola.
