Abstract:
:The application of anaerobically digested biosolids as a nutrient source for pecan, Carya illinoinensis (Wangeh.) K. Koch, cultivar Western, was evaluated. Conventional NPK fertilizers (CF) and biosolids included a treatment with the rhizospheric fungi Pisolithus tinctorius+Scleroderma sp. and Trichoderma sp. After an average of three years, the tree trunks with biosolid treatment grew 9.5% more than with CF; the length of the bearing shoots was 18.1 and 18.3cm and the production of nuts/tree was 9.26 and 8.75kg for pecans with CF and with biosolids, respectively. Western foliar nutrient concentration and nut quality were statistically equal in trees with CF and with biosolids. Soil inoculation with mycorrhizal fungi improved shoot growth by 19.4% when CF was applied, but did not when biosolids were used. Nutrient status and yield did not increase with mycorrhizal fungi. The addition of Trichoderma sp. did not favor any of the variables evaluated with both nutrient sources. Biosolids are efficient fertilizer at promoting the growth, production and nut quality of pecan trees.
