A rapid method of analysis of nitrate in plant sap using Merck test strips was evaluated. Accuracy and precision of the strips was found to be acceptable in a test in which aqueous samples were tested by four operators. Nitrate N was measured in five vegetable crops at two stages of growth by two methods: squeezing sap from fresh petiole or stem tissue with NO3-N determination by Merck test strip; and acetic acid extraction from dried petiole or stem tissue with NO3-N determination by autoanalyser. The relationship between the two methods was found to be highly significant with coefficient of determination exceeding 0.82 in eight out of 10 cases (crops x sampling dates). When the strip results were corrected for moisture content the relationship with the laboratory method improved in most cases. |
