| dc.description | Potato (Solanum tuberosum L.) is an important staple food for the largest number of
peoples in the world belongs to the family Solanaceae (known as the nightshades)
(Solomon and Barker, 2001). It is also known as 'The king of vegetables', has
emerged as fourth most important food crop (Ghosh and De, 2011). However,
there is no doubt that it was introduced in this sub-continent in early 17 century,
only about 40 years after its first introduction in Europe (Pushkarnath, 1969).
Potatoes were first introduced outside the Andes region four centuries ago, and
have become an integral part of much of the world's cuisine (Keeps, 1979). The
potato originated in the region of southern Peru. Potatoes were first domesticated
in Peru between 8000 BC and 5000 BC (Ahmad, 1977). It is the world's fourthlargest food crop, following rice, wheat and maize (Van-Diepan, 2003). The
English word potato comes from Spanish patata (the name used in Spain). There
are about five thousand potato varieties worldwide. Today it is the 4 most
important food crop in the world, with annual production approaching 300
million tons (CIP, 2007). Since then, a good number of potato varieties were
gradually introduced and cultivated in this country. The potato plant is an
herbaceous annual plant. It is propagated vegetatively by planting tuber that
gradually bears two or more eyes. | en_US |
| dc.description.abstract | An experiment was conducted at the Central Farm, HSTU campus, Dinajpur
during the period from November 2012 to March 2013. The aim of the present
study was to identfy the most productive variety and also to find out the most
optimum level of Maleic Hydrazide (MH) and suitable time of its foliar
application on the aspect of better growth development and greater yield of
three modern varieties of potato under the regional condition of AEZ-1. Three
potato were namely Diamant (V1), Cardinal (V2) and Multa (V3), four different
concentrations of MH (0, 500, 1500 and 2500 ppm), its foliar application time in
the trial field were used as level factor A, B and C, respectively. The experiment
was laid out in a three factors RCBD with four replications. The result revealed
that most of the yield components and yield were significantly influenced by
different varieties of potato, different levels of concentration of hormone and
two planting dates of hormone. The treatment combination of second spray of
hormone on 45 days after planting and 500 ppm maelic hydrazide gave the
highest yield of potato tuber (47.58 kg t/ha) and the lowest yield (40.30 kg t/ha)
was obtained from second spray of hormone and 1500 ppm maelic hyrdrazide.
Less number of days required for germination of potato tuber, higher branch
angle per plant, higher diameter of main stem, higher number of leaflets per
plant, highest number of compound leaf per plant, weight of tuber per plant and
weight of tuber per hactor were obtained from the treatment V1. In case of
different grade of tuber viz number of tuber >45 mm, 35-45 mm diameter,
number of tuber per plant were significantly highest from V1 treatment. The
highest number of tuber per plant was observed in the treatment of 500 ppm
MH. The highest number of <28 mm diameter of potato was observed from the
variety V3. The weight of tuber >45 mm diameter, and dry weight of tuber per
plant (gm) was observed in the treatment D2H1. The combined effect of D2V1
was significant for number of compound leaf per plant and number of tuber (28-
35) mm diameter in the treatment V1H1. The treatment combination D2V2H1
produced highest diameter of main stem in potato. The lowest diameter (9.51
mm) was obtained from D2V3H2. | en_US |
