ENUMERATION OF FOLIAR FERTILIZER EFFICIENCY IN INDIAa??S TOP COMMERCIAL CROP-TEA

摘要

The present study was carriedout to compare the foliar fertilizer efficiency in determining the micronutrients and macronutrient status of tea (Camellia sinensis) plantations. Leaf samples were collected from the Woodland Estate in Ooty. The results; showed that Fe, Cu, Zn and Mn contents of NO BCX sample were 44.5, 21.02, 117.8, 0 ppm respectively. Fe, Cu, Zn and Mn contents of BCX sprayed sample were determined as 52.38, 21.06, 122.3, 0 ppm respectively. Ca, Mg, Na, K, B, S contents of NO BCX sample were 2.0 ml,7.0 ml, 0, 18, 5838, 371.16 respectively. Ca, Mg, Na, K, B, S contents of BCX sample were 3.5 ml, 8.6 ml, 0, 17, 6528, 371.29 respectively. Consequently, the results indicated that tea plantations with foliar fertilizers were more efficient in absorbing the nutrients than the tea plantations wherein only normal fertilizers were used.
