It contains all response variables presented in this article. The first row contains the capitalized variable names used in column definitions below.</p> <p>Column definitions:</p> <p>1. PLOT – An integer to identify the 32 experimental plots</p> <p>2. N – A value of 1 (one) identifies an N addition plot. A value of 0 (zero) identifies a plot that did not receive added N.</p> <p>3. P – A value of 1 (one) identifies a P addition plot. A value of 0 (zero) identifies a plot that did not receive added P.</p> <p>4. K – A value of 1 (one) identifies a K addition plot. A value of 0 (zero) identifies a plot that did not receive added K.</p> <p>5. BLOCK – An integer to identify the two blocks within each replicate. In the balanced, incomplete blocks design, one block in each replicate includes the treatments +N, +P, +K and +NPK and the      second block in each replicate includes the treatments CONTROL, +NP, +NK and +PK.
