Description The pres ent inv es tigat ion entit le d, “ Influen ce of time and
intensity of pruning on the high density planted mango cv. Kesar”
was undertaken at Agriculture Experimental Station, Navsari
Agriculture University, At & Po: Paria, Ta: Pardi Dist. Valsad
during the year 2012-13 and 2013-14. This experiment consists of
two factors v iz., pruning t ime i.e. First fortnight of June (T1 ),
second fortnight of June (T2), first fortnight of July (T3) and
second fortnight of July (T4), and pruning intensity i.e. 25 cm, 50
cm and 75 cm as wel l as un-pruned as control, which are repl icated
thrice in Randomized Block Design wi th factorial concept.
The minimum days taken to vegetative shoot emerges,
highest percentage of vegetat ive shoot emerges at 45, 60 and 90
days after pruning, number of hermaphrodite f lowers, the highest
percentage of fruit set at harvest, maximum yield and the highest
number of fruits were recorded in f irst fortnight of July. Whi le,
minimum days taken to flowering was noted with second fortnight
of July. The maximum percetage of flowering was observed with
second fortnight of June. The individual effect of different
pruning t ime on bio mass, shoot lenght, shoot girth , number of
leaves, lenght of panicle,staminate f lowers, sex ratio, percentage of
fruit set at pea and marble stage, maturity days, al l quality
parameters viz. , weight of fruits, total soluble solid, acidity,
reducing sugar, non-reducing sugar, total suaga rs, ascorbic acid,
organolapt i evalution were found non significant.
The maximum shoot girth, minimum days taken to vegetative
shoot emerges i.e. with the increasing pruning intensity , days taken
to vegetat ive shoots were delay, the highest percentage of
vegetative shoot emerges at 45, 60 and 90 days after pruning,
minimum days taken to f lowering, the highest percentage of
flowering and percentage of f rut i set at harvest, maximum yield
was found with pruning at 25 cm gives 8.77 kg higher f rui t
product ion per plant than 75 cm of pruning. Similarly, number of
fruits per t ree and frui t weight were also observed with 25 cm of
pruning intensi ty. While, maximum bio mass, the highest
percentage of flowering directly without vegetat ive shoot emerge
and minimum maturity days were noted with 75 cm of pruning
intensity. However, shoot lenght, number of leaves, lenght of
panicle, number of staminate f lowers, hermaphrodite f lowers, sex
ratio, percentage of fruit set at pea and marble stage and al l
quali ty parameters viz., weight of f ruits, total soluble solid, acidity,
reducing sugar, non-reducing sugar, total suagar s, ascorbic acid,
organolapt ic evalut ion were remain unaffected with variying
pruning intensity.
The treatment combination of f irst fortnight of July with 25
cm of pruning intensity (T3P1) recorded significantly the highest
percentage of vegetative shoot emergence at 45 and 60 days after
pruning, highest percentage of f ruit set at harvest and highest
yield.
The control vs rest analysis showed significant varia tion in
almost al l parameters studied. The maximum bio mass, minimum
days taken to vegetat ive shoot emerge and the highest percentage
of vegetative shoot emerge at 45, 60 and 90 days after pruning,
minimum days taken to flowering , maximum percentage of
flowering and percentage of f lowering without vegetat ive shoot
emerges, maximum length of panicle, hermaphrodite f lower and
sex ratio, the highest percentage of f ruit set at harvest, maximum
yield, highest number of f ruits per t ree and highest weight were
recorded with pruned t reatments as compared to unprune d
treatment (control). While remaining parameters were found nonsignificant.
