This book focuses on the production technology of temperate nuts. It explores cultivar and plant improvement, development and selection of rootstocks, plant–water relations and irrigation, canopy architecture, and postharvest packaging of nut fruits. It also deals with organic approaches, biotechnological interventions, diseases, and pest management. Contributing authors address nut fruits such as walnut, pecan nut, chestnut, and hazel nut on different recent aspects. The development achieved in the fruit sector is indicative of the fact that there is growing demand of fruit produce. Temperate nuts with health benefits and market acceptability have best sources of fat, fiber, protein, and mineral. They provide dietary fiber, potassium, and a variety of health-protective bioactive compounds. Apart from the health benefits, production of temperate nuts improves the economy of the country as these are very good source of income and employment. In addition, there is wide diversification in the production pattern of nuts globally. Increased production technology such as hybrids, high-yielding selections/ varieties, improved propagation techniques, and increased use of fertilizers and manures have brought spectacular increase in the production of nut fruits. This book is of interest to teachers, scientists, researchers, and scholars. Also, the book serves as additional reading material for undergraduate and postgraduate students of agriculture and horticulture. Horticulture nurseries and orchard industries also find this to be a useful read.
