This research was carried out through the 201-2011 and 201-/2012 seasons
on 26-year-old trees of AL– Ashouri Pistachio cultivar grown in clay soil, in a
private orchard in Souran region (Hama province). Four types of organic green
fertilizers (Len
tils, Vetch, equal mixture from Lentils and Vetch and mix of
these legumes with barley), in addition to the control, to study their effects on
some quantitative and qualitative characteristics of pistachio nut. Results
showed that the use of green fertilizers caused significant increase in studied
indicators and the best treatment was mix of legumes with barley (45% Lentils,
45% vetch, 10% Barley), which achieved the highest significant values، where
average of weight of the 100 nuts was 107.45 g during the two seasons, the
average of weight of the 100 kernel was 67.08 g, average of length of shell was
20.85mm and an annual yield was 32 kg/ tree, compared with control, which
achieved 87.50g, 40.25g, 18.08 mm and 16.75 kg, respectively.
