| dc.description.abstract | An experiment was conducted to find out the effects of planting and haulm
pulling dates to obtain maximum potential yield with better quality of potato
cultivar (Cardinal). The experimental treatment was arranged as a two factors
factorial experiment where factor ‘A’ was different sowing times (2nd October, 1st
November, 1st December and 31st December) and factor ‘B’ was different haulm
pulling time (70DAS, 77DAS, 84DAS AND 91DAS). The Randomized Complete
Block Design was used with 3 replication in the field during (2016-2017). In this
experiment different planting dates and different haulm pulling dates influenced
plot yield (kg), yield (ton/ha), no of tuber/ha, percentage of edible potato and
marketable potato/ha. Four planting dates (2nd October, 1st November, 1st
December and 31st December) were evaluated where the highest yield (ton/ha) and
marketable potato/ha were recorded from 1st November planting. Minimum
incidence of several diseases was observed at 1st November. Similarly four haulm
pulling dates (70DAS, 77DAS, 84DAS and 91DAS) were evaluated where the
highest yield (ton/ha), no of tuber/ha and marketable potato/ha were recorded
from 91 days after sowing but maximum post harvest disease incidence was also
observed at that haulm pulling time. With increasing of the time of haulm pulling,
the post harvest disease incidence was also increased. That’
s why 91DAS was not
considered perfect time for haulm pulling. On the other hand yield was
comparatively better and disease incidence was lower at 84 DAS. So the results
showed that the best time for planting in 1st November and haulm pulling time at
84 days after sowing. | en_US |
