| dc.description | Tomato (Lycopersicon esculenlum Mill.) is one of the most important, popular and
nutritious vegetable crops in Bangladesh which belongs to the family Solanaceae.
It is widely grown not only in Bangladesh but also in every country the world.
Tomato ranks third in terms of world vegetables production and tops the list of
canned vegetables (Choudhury 1979). It is originated in tropical America
(Salunkhe et al. 1987) which includes Peru-Ecuador-Bolivia areas of Andes
(Kalloo 1986). The present leading tomato producing countries of the world are
China, United States of America, India, Egypt Turkey, Iran, Italy, Mexico, Brazil,
and Indonesia (FAO 2002). | en_US |
| dc.description.abstract | An experiment was conducted at the Crop Physiology and Ecology research farm
in Hajee Mohammad Danesh Science and Technology University, Dinajpur
during the period from November 2011 to March 2012 to study the effect of
different levels of nitrogen and irrigation on the growth and yield of tomato. Four
levels of nitrogen (N) viz., 0, 90, 120, and 150kgNha’! and three levels of
irrigation (I) viz., 10, 15, and 22 mm were used in 36 combinations. The
experiment was laid out in two factors RCBD with three replications. The size of
unit plot was 1.5m x 1.5m and the date of planting was 22nd November 2011.
Different level of nitrogen showed significant variations in respect of all the
characters studied. Plant grown with 150kg Nha’ gave the highest plant height,
total number of leaves, days to first flowering, flower cluster, number of fruits per
plant, individual fruit weight, fruit length, fruit diameter, branch number,
secondary branch number, total dry matter content, days to 50% flowering, fruit
yield (80 tha’). Plants grown with 22mm gave the highest fruit yield. Combined
effect of nitrogen and irrigation levels exhibited significant variations on plant
height, number of leaves per plant, days to first flowering, number of fruits per
cluster, weight of individual fruit. Highest total fruit yield (82 tha’') was obtained
from the treatment combination of 150kgNha‘' with 22mm water application | en_US |
