The experiment was carried out during2013-2014 Miaar Shaker village (Tartous) to determine the best method of irrigation on growth and productivity of Tomato plant in plastic green-house. Three method of irrigation were used in the experiment :(furro
w surface , surface drip and subsurface drip irrigation). Growth of plants, productivity and fruit quality were studies.
The results showed that surface and subsurface drip irrigation give more plant growth (leaves number and leaves area) more flowering and fruit production as compared with furrow irrigation method .The leaves number and leaves area in plant with surface drip irrigation was 31.49 leaves and 17078/plant while these number reached only to 22.91 leaves and 7057.86/plant in the furrow irrigation with significant difference . The productivity of plants was also higher in surface drip irrigation method(4.75 kg/ plant) without significant difference as compared with subsurface irrigation method and with significant difference as compared with furrow irrigation method (3.95 kg/ plant). The quality of fruits was better in surface drip irrigation (8.28% dry material ,5.02% TSS and 28.23mg vitamin c /100g) in fresh matter while these number were 7.18%, 4.98% and 20.96 mg/100g in furrow .
The irrigation method haven't affect in the: plant length ,and acidity percentage.
The study was conducted in Jableh during 2012/2013 in plastic green house on sweet
and hot pepper hybrids to study the effect of plant density on growth and productivity.
The hybrid VIGARIO(sweet pepper) and hybrid ERAD (hot pepper)variety were
ap
plied in six treatment and four replication .It was showed that the highest number of
flowers were recorded in VIGARIO variety in space (50x60)cm to amount(18.33)
flower/plant ,while the the highest number of fruits were recorded in space(50x40)cm to
amount(20.98)fruit/plant and the earlest yield (390.6)g/m2and the highest total
(3486)g/m2productivity were found in space (50x40)cm . IRAD hybrid give the highest
number of flower in space (50x40)cm to amount(28.23) flower/plant,while the hieghest
number of fruit were recorded in space (40x60)cm to amount(107.17) fruit/plant and the
highest productivity were found in space(50x40)cm to amount (9485.7)g/m2.
