Nuts of any tree of the Juglans genus are called walnuts. A walnut cannot be described as a true botanical nut since it is actually the seed of a drupe or drupaceous nut.
There are two major species of walnuts, the English walnut, and the black walnut. The former is also known as the Persian walnut since it originated in Persia. The latter traces its origin to North America. The English hybrid is grown on a commercial scale and numerous cultivars have been developed over time.
Walnuts usually grow well in cool climatic conditions. The yield of the crop is adversely affected by high temperatures. An evenly distributed annual rainfall of about 800 mm generates an optimum yield of the crop. Walnuts grow best in well-drained deep silt loamy or clay loamy soils.
