Extension Publications for Pecans
Nutritional, Environmental and Cultural Disorders of Pecan
(B 1332)
Although many problems regarding pecan production result from pest or disease pressure, the crop may also be adversely affected by nutritional imbalances, nutrient deficiencies, or environmentally induced disorders. These are some of the more difficult problems to diagnose. Some nutrients may be more available than others on certain soil types and under certain soil conditions. Additionally, complex interactions often occur between nutrients, which influence uptake by the pecan tree. Pecans can also be quite sensitive to environmental conditions, which stress the tree, limiting its growth and productivity.
Commercial Pecan Spray Guide
(B 841)
This publication provides guidance for insect, disease, and weed control in commercial pecan orchards for 2023.
Pecan Varieties for Georgia Orchards
(C 898)
The most fundamental step in pecan production is the selection of varieties or cultivars to be planted in the orchard. Planting the wrong pecan variety can be a costly mistake, resulting in considerable expense. This publication includes descriptions and photos of pecan varieties suitable for planting in Georgia orchards.
Drip Irrigation in Pecans
(B 936)
Research conducted on drip-irrigated pecans in Georgia over the past several years has shown that drip irrigation is highly beneficial even in wet years. The objective of drip irrigation is to supply each plant with sufficient soil moisture to meet transpiration demands. Drip irrigation offers unique agronomic, agrotechnical and economic advantages for the efficient use of water.
Mouse Ear of Pecan
(C 893)
Mouse ear of pecan is a growth abnormality resulting from a deficiency of nickel in the pecan tree. Only recently, the discovery was made that mouse ear indicates a severe nickel deficiency. The disorder occurs most frequently on newly transplanted trees in established orchards, but can also occur on sites where pecan has not previously been grown.
Cultural Management of Commercial Pecan Orchards
(B 1304)
In order for a commercial pecan operation to be consistently successful, the goal of the operation should be annual production of a moderate crop of high quality nuts, rather than the production of a high yield in a single given year. Culturally, there are several basic factors that will help to promote optimum profitability with a commercial pecan orchard.
Establishing a Pecan Orchard
(B 1314)
A well-planned, organized orchard will be more efficient, require less input and offer larger potential returns. Select the orchard location based on its soil type, drainage, water table and land topography. Straight rows in planted orchards make maintenance, irrigation and harvest easier. Tree growth and spacing requirements can also be anticipated for the early planting and subsequent orchard thinnings.
Pecan Trees for the Home or Backyard Orchard
(B 1348)
Pecan trees are commonly found surrounding both urban and rural dwellings throughout Georgia. They can enhance the environment and provide additional income from the sale of nuts. This publication contains comprehensive information about pecan trees for the home or backyard orchard.
Clover Management in Pecan Orchards
(B 1360)
An orchard floor provides a working surface for orchard operations and influences activities in the trees, which produce the crop. An efficient orchard floor cover does not compete heavily with trees for moisture and nutrients and is compatible with orchard insect populations. While weed competition with tree roots is significant throughout the life of the tree, in a newly planted orchard, weed competition can significantly reduce young tree survival and can stunt tree growth. Weed competition can reduce tree growth and yield, as well as promote alternate bearing in mature trees.
Budding and Grafting of Pecan
(B 1376)
Individuals who propagate trees have their own personal preferences with regard to propagation methods. As with many practices related to pecan production, timing is important for successful propagation.
