Abstract :
A survey was conducted to assess the Zn, Cu, Fe, Mn, and B status of 50 peach (Prunuspersical L.) orchards in Swat Valley of Khyber Pakhtunkhwa province during 2008. Soil at 0-15, 15-30 and 30-45 cm along with leaf samples were collected from each orchard and analyzed for micronutrients contents. The soil of surveyed orchards were either loam (38.3 %), silt loam (38.3 %), sandy loam (19.2 %), loamy sand (2.1 %) or clay loam (2.1 %) in texture and none of the soil samples at 0-15 cm was deficient in AB-DTPA extractable Cu, Zn, Fe, Mn or HCl extractable B. The lower depths (15-45 cm) were deficient in Zn and B only in 4-8 % peach orchards. The leaf tissue analysis showed that none of the orchards was low in Cu, Mn and Fe. However, B was deficient in 6 % and Zn in 2 % peach orchards. No or poor correlation was found between soil and plants tests for diagnosing micronutrient deficiencies in peach orchards. The significant correlation of surface soil (0-15 cm) with cumulative micronutrient contents of the profile (0-45 cm) revealed that the surface soil analysis can be used to measure pattern in micronutrients fertility of the profile. These results suggested that peach orchards in Swat valley are not yet seriously deficient in micronutrients but the deficiency is appearing. Therefore, these orchards should be assessed regularly for micronutrients status for timely management.
