Description The Diagnosis and Recommendation Integrated System (DRIS) was used for developing foliar diagnostic norms for black pepper. The nutritional survey carried out in
578 black pepper gardens covered major pepper growing areas of Kerala and Karnataka states Indicated that 63.6 per cent 01 the vines were high yielders. An optimum yield ranging from 561 to 4526 g per vine can be achieved if- the recently matured leaf CDntains 1.65 to 2.79
per cent N, 0.11 to 0.26 per cent P, 1.18 to 2.84 per cent K, 1.42 to 3.33 per cent Ca, 0.40 to 0.60 per cent Mg, 0.09 to 0.29 per cent S, 126 10 1145 ppm Fe, 109 to 721 ppm Mn, 21 to 67 ppm In and 16 to 120 ppm Cu. Diagnosis of 210 low yielding pepper gardens
indicated wide spread deficiency of Mg (41 Der cent), sub-optimum supply of N (7 per cent), P (18 per cenl), K and Ca (111 per cent each). Mg (31 per cent) and In (16 per cent). The yield was low due to excessive Cu. to the extent of 20 per cent in the leaf due to spraying
of copper fungicides to check fungal diseases.ยท The deficiency of Mg, hidden hunger of first order (In), second order (P) and third order (N) were also identified, to take care of subsequent yield limiting nutritional 1actors on correction of most deficient nutrient.
