Effect of nitrate and ammonium nitrogen on the growth of the lowbush blueberry

Summary

This 1966 study by Townsend investigated the differential effects of nitrate versus ammonium nitrogen on lowbush blueberry growth, a species of commercial and ecological importance in eastern North America. As a short communication in a peer-reviewed journal, it likely presents experimental findings from a controlled trial comparing nitrogen form uptake and growth response. The work contributes to understanding nutrient management in lowbush blueberry cultivation, though the specific mechanistic findings and magnitude of effects are not apparent from the title alone.

Regional applicability

Lowbush blueberry (Vaccinium angustifolium) is wild-harvested and cultivated across Atlantic Canada and parts of the northeastern United States, but is not a significant commercial crop in the United Kingdom. Findings on nitrogen form preference may have limited direct applicability to UK horticulture, though principles of nitrogen nutrition in acid-loving berry crops could be transferable.

Key measures

Plant growth parameters (likely shoot length, dry matter, or biomass; exact metrics unclear from title alone)

Outcomes reported

The study examined how nitrate and ammonium nitrogen sources affected the growth of lowbush blueberry plants. Specific growth metrics were likely measured, though the precise outcome variables are not stated in the available metadata.
