The germination rate for untreated caper seeds is quite low. Some seed treatments were
tested to increase germination. Freshly harvested seeds of the year 1999 germinated at 29%
when immersed for 12 h in 2000 ppm GA 3 . In control seed lots the germination rate was
only 1% (Fig. 3).

Oregano (Origanum onites L.)
The effects of three levels of nitrogen application (0, 60, 120 kg/ha) and four different
planting patterns on Origanum onites L. were investigated for three years (between 1991 and
1993) in three locations. Green herb and drug leaf yield and essential oil percentage were
measured. Yields and essential oil percentage were generally highest at 45 x 15 cm with an
application of 60 kg/ha nitrogen (Table 2).
