Zinc and copper in the youngest matured leaf of the middle one-third portion of the vine was found to have the highest correlation with the soil available zinc (r= 0.892 * *) and copper (r = 0.766 ••) respectively, thus showing the possibility of using the youngest matured leaf as the indicator leaf of pepper for these nutrients.enpepperzinccopperleaf compositionAssessment of soil zinc and copper as reflected by the leaf composition of pepper (Piper nigrum L.)Article
