In addition, temperature plays an important role in flower regulation of fruit. Low temperature and soil moisture could induce floral bud formation. It’s a physiological reaction of plant that could be promoted root growth, lengthens the flowering period, increases the number of branches per plant, number of flower forming pods. Besides internal and external factors, cashew crops could be induced to flower by environmental factors and cultural practices. Therefore, the means that can induce flowering should be considered. To date, very few studies aim to understand the physiology of cashew on the flower induction and development. Therefore, this study was focused on investigation of soil moisture, soil pH, nitrogen of the soil and leaves and field temperature during flowering of cashew trees.
