In this experiment, first-year pecan seedlings were fertigated with varying amounts of calcium nitrate in an attempt to stimulate growth rates. Pecan seedlings were fertigated every 2 weeks from may through october for a total of 10 applications. Total amounts of nitrogen (n) applied by fertigation were 0, 4, 10, 20, and 40 g of n per seedling.
Agronomic management modifies the soil bacterial communities and may alter the carbon fractions. Here, we identify differences in several chemical and biological soil variables, as well as bacterial composition between organic (org) and conventional (conv) agronomic management in pecan (carya illinoinensis) orchards located in coahuila, mexico.

Nitrogen (n) is an essential element for plant growth, and pecan needs n fer-tilizer during the nut enlargement and nut filling stages (byford, 2005a). Nitrogen application rates are usually much higher than rates for other nutrients (wells, 2013), which increases the risk of n leaching in irrigated pecan orchards.
Of nitrogen and phosphorus response in young (two- and three-year-old), non- bearing,'western schley' and 'wichita' varieties of pecan (carya illinoinensis.
Koch] has been studied for nearly a century, however considerable variability exists in the literature regarding fertilizer form, source, placement method, quantity/rate and application timing effects on growth, crop load, kernel.
Pecan pab-based inhibition elisa could detect pecan proteins as low as 32 ng/ml. The assay, however, was not suitable for specific detection of pecan in foods as it showed cross-reactivity to various tree nut and seed proteins.

This research quantifies soil water and soil nitrate‐nitrogen (no 3 –n) (mg l −1 of soil) variations with depth, root no 3 –n (kg ha −1) uptake, and no 3 –n (kg ha −1) balance for the 100‐cm soil profile during two growing seasons in a flood‐irrigated pecan orchard.
Bulk soils were collected to a depth of 20 cm from three sites: a 21-year old pecan (carya illinoinensis)/bluegrass (poa trivialis) intercrop (pecan site) in north-central missouri, a 12-year old silver maple (acer saccharinum)/soybean (glycine max)–maize (zea mays) rotation (maple site) in northeastern missouri and a missouri department of conservation-managed restored warm season grasses.
The main ingredients needed by pecan trees in arizona include adequate space, water, nitrogen, zinc and more water. A mature pecan tree requires nearly 34,000 gallons of water per year. With annual average yields of 40 to 50 pounds per tree, this amounts to nearly 680 to 850 gallons of water per pound of nuts, depending on soil type.
A pecan-cotton alley cropping system was established in northwestern florida in spring 2001 to assess tree-crop competition for nitrogen (n) and its effect on mineralization rates and groundwater nitrate levels, and nitrogen use efficiency.

Due to the increasing cost of fertilizers and the negative effect of their excessive use on the environment, a more rational way of nutrient application is needed. The present research evaluated nitrogen use efficiency (nue), productivity and quality of pecan.
