Abstract
Prevailing Zn issue at the country level and some studies of fruit orchards highlighting Zn deficiency gave rise to the evaluation of apple orchards in Sanjavi Tehsil. Soil and leaf tissue samples were collected from twenty-five apple orchards (eight trees from each) covering four union councils (Sanjavi, Mana, Warchm and Poi) of Sanjavi Tehsil. Four cores were dug under each tree to have a representative soil sample. Leaves were collected from the middle of each newly emerged twelve shoots of each tree. According to the critical nutrient level (CNL) approach, there was no deficiency of plant available Zn in soil. All the samples (100%) were above the adequacy limit of 1.5 mg kg-1. Nonetheless, 7 out of 25 orchards had relatively less available Zn (1.8 to 3.0 mg kg-1) over others. In contrast to available Zn, the leaf tissue samples were at the edge of adequacy level. In other words, 100% samples were marginal (25-150 mg kg-1) and if no application is carried out in near future, soil available and leaf tissue Zn, both may further lower down. Positive and significant relationships illustrated that organic matter contributed to soil available and leaf tissue Zn
