Department of Horticulture, College of Agriculture, GB Pant University of Agriculture and Technology, Pantnagar, Uttarakhand-263145, India

Abstract

The chemical diagnosis of nutritional status of karonda (Carissa carandas L.) plant by leaf analysis was done to study the effect of leaf age, leaf position and sample size on foliar nutrient composition of karonda. The results showed that leaf age has significant influence on leaf mineral content of karonda while the leaf position on the shoot has significant influence on potassium, calcium, manganese and copper. Sample size showed significant influence on potassium and manganese content of karonda. Significant influence of interaction between leaf age and sample size was found on dry matter accumulation, potassium, iron and manganese content of karonda. Study suggested that sample size of 30 leaves from four month old leaves should be sampled from middle position for nutrient assessment in karonda.
