Abstract

      Diagnosis and Recommendation Integrated System (DRIS) and deviation from optimum percentage (DOP) method are from important methods for interpretation of the results of chemical analysis and diagnosis of nutritional status of plants. In order to evaluate the nutritional status of squash (Lagenaria Vulgaris) through DRIS and DOP and to determine DRIS norms for this crop, 122 leaf samples were collected from squash fields in Khoy and N, P, K, Ca, Mg, Fe, Mn, Zn, Cu and B were analyzed. The squash fields were divided into high and low yielding groups. The DRIS norms were calculated from high yielding fields’ data. The mean of nutrient concentration in high yielding fields were selected as norms for the calculation of DOP indices. Too, Results showed that there were significantly differences between high and low yielding fields in terms of nutrients concentration and their ratios. Sufficiency ranges of nutrients concentration in squash leaves were determined as 2/7-4/0, 0/32-0/46, 3/3-4/6, 1/3-1/9 and 0/53-0/78 for N, P, K, Ca and Mg and 155-206, 116-154, 49/5-66/7, 10/9-15/4 and 57/4-70/8 mg/kg for Fe, Mn, Zn, Cu and B respectively. Based on DRIS and DOP indices, potassium and zinc had the most negative indices among macro and micro nutrients, respectively. DRIS and DOP nutritional balance indices (NBI) in low yielding fields were greater than zero indicating nutritional imbalances in these fields.
