Abstract
An experiment was conducted to study the influence of soil moisture on
vegetative growth, flowering and fruiting in different Mango hybrids and varieties
at “A” block, Gandhi Krishi Vignana Kendra, University of Agricultural Sciences,
Bengaluru during the year 2008-2009. For the study Mango varieties Mallika,
Arka Anmol, Alphonso and Baneshan were selected and data was analyzed by
using regression equation. The studies indicate that the highest water storage
capacity was found in the variety Alphonso (149.81 mm) followed by Arka Anmol
(140 mm), Mallika (139.81 mm) and lowest was in Baneshan (138.03 mm). The
actual water utilized by tree worked out by using a water balance technique and it
was found in the variety Alphonso (407.62 mm) followed by Mallika (401.28 mm)
and Arka Anmol (389.98 mm), the highest total runoff 317.85 mm was recorded in
case of Mallika and least 286.98 mm was observed in Baneshan.
The influence of soil water storage on growth, flowering and fruiting is
significantly influenced as compared to actual water utilized by the trees among
the varieties, moisture and temperature influenced on number of flowers per
panicle. The hybrid Mallika (283.45) was found to have more number of bisexual
flowers where as less in case of Baneshan (78.00). The percentage of fruit set was
more in Arka Anmol (9.20) and lowest in Baneshan (7.30), where as the fruit
retention per panicle was more in case of Mallika (2.2 per cent). The fruits per tree
was more in Mallika (150) and Alphonso (145) and lowest in Baneshan (80).
The studies indicated that the moisture plays major role in the growth,
flowering, fruit set and yield of Mango varieties
