Abstract
lley. Representative soil (0-30 cm depth) and leaf samples were collected from 40 plum orchards during May 2008. Results showed that the concentration of AB-DTPA extractable Zn ranged from 0.04 to 1.34 µg g-1, Mn 0.04 to 19.8 µg g-1, Fe 4.8 to 21.0 µg g-1, Cu 0.43 to 10.6 µg g-1 and available B 0.01 to 0.62 µg g-1 in soil. Based on soil test, Zn was deficient in 95%, B in 90% and Mn in 5% plum orchards. The leaf analysis showed that the concentration of Zn ranged from 19.6 to 99.9 µg g-1, Mn from 20.2 to 77.8 µg g-1, Fe from 11.0 to 158.0 µg g-1, Cu from 2.60 to 74.0 µg g-1, and B from 5 to 26 µg g-1 dry matter. Based on tissue test, Zn was deficient in 17%, Mn in 2%, Fe in 45%, Cu in 13% and B in 95% plum orchards. The soils of plum orchards were alkaline in reaction (pH 7.79 to 8.62), non-saline (EC 0.08 to 0.21ds m-1), low in organic matter (0.28 to 3. 04) and were calcareous in nature (Lime 4.70 to 22.5%). Present survey suggested that the plum orchards require special attention to overcome micronutrients deficiencies. Hence, the growers are advised to use microlley.
