Nitrogen fertilization for Bartlett pears
1967
A Hewitt | J Beutel | O Lilleland
A leaf nitrogen content of 2.3% or higher in June should be considered their goal by pear growers, according to this study in Lake and Sacramento counties. Leaf analysis offers a good basis for determining whether sufficient nitrogen exists for adequate fruit set. Once this level has been obtained, an individual orchard evaluation is necessary to determine the minimum rate needed to maintain it. However, if higher levels are encountered, there need be little concern about adverse effects on fruit quality, but only that more money may have been spent for fertilizer than necessary.
