It is also called as filbert or cobnut.
Hazel nut is a shrub or trees grown for its edible nuts.
Hazelnut originates from Europe and South East Asia.
The main hazelnut producing countries are Turkey, Italy, Spain, USA and Greece.
World production of hazelnuts (in shells) was 7,43,455 tones.
He USA produces approximately 25-30,000 tones of in shell hazelnut in Oregon and it also imports nearly 4,000 tones.
Filberts are hardy plants which can survive adverse growing conditions.
They should be grown in a soil which is at least 2.4 to 3 m (8-10 ft) deep and will grow optimally in well-draining, fertile loams with a pH between 5.5 and 7.5.
The hazelnut tree is quite hardy but only produces satisfactory crops under moderate climate conditions.
Temperature of minus 10°C is critical, especially if accompanied by wind.
Hazelnuts are more shallow rooted than most fruit and nut trees, and do not tolerate wet soils.
Soils must be moderately fertile and heavy clay soils should be avoided.
Hazels will grow in pH ranging from 4.5 to 8.5, but around pH 7 is ideal.
