This
study was conducted to investigate the effect of different
irrigation and nitrogen levels on lettuce yield
characteristics in greenhouse condition from December 2006
to March 2007. Irrigation levels of 100% of total class A
pan (S1), 80% of total class A pan (S2), 60% of total class
A pan (S3) and nitrogen levels of 0 kg ha-1 (N1),
100 kg ha-1 (N2), 200 kg ha-1 (N3),
and 300 kg ha-1 (N4) were applied by drip system.
Irrigation levels did not show any significant effect on
head weight, marketable head weight, number of leaves,
height of plants, head circle, root length, and root extent
except core length and total soluble solid, TSS. The highest
head and marketable head weight were found as 355.17 and
334.78 g in S1 application, respectively. Nitrogen levels
had no significant effect on measured parameters. These
values were the highest as 365.06 and 342.93 g in N3
application.
Key
words: Lettuce, drip irrigation, nitrogen applications,
greenhouse, head weight. |
