Abstract:
A field experiment was accomplished in the Horticulture farm of Sher-e-Bangla
Agricultural University, Dhaka during the period from November 2016 to March 2017 to
evaluate the bio-stimulating effect of Trichoderma on potato germplasm. Potato
germplasm viz. G
1
(Sokal), G
2
(Bijita), G
3
(JP Blue yellow), G
4
(JP Blue white), G
(Burma-1), G
6
(Burma-2), G
7
(Cardinal as check) and Trichoderma application : T
(No
trichoderma application), T
1
(Once application), T
(Twice application) were used in this
experiment arranged in Randomized Complete Block Design with three replications.
Data on different growth, physiological and yield attributes parameters were taken in
which all the treatment showed significant variations. Among germplasm, maximum
tuber length (8.98 cm), tuber weight (133.4 g), yield/ hill (0.54 kg), dry matter content
(17.48 %) were found from G
1
2
(Sokal) whereas minimum in germplasm G
(JP Blue
white)
and for trichoderma application, maximum tuber number (5.05), tuber length (7.75
cm), tuber weight (106 g), total yield (34.4 t), dry matter percentage (19.99) found in
twice application. Maximum yield per hectare (38.92 t) were found in G
and
minimum (21.7 t) in G
4
T
. Trichoderma two times spray significantly decreased the
disease infestation. In view of overall performances, germplasm G
0
with twice
application of trichoderma has potentiality for quality potato production.
