摘要: This study was conducted to assess the micronutrient status of soils and associated plant tissues in major tomato growing areas Taluka Badin, Sindh. Composite soil (3 rd leaf from top) samples were collected 32 Badin analyzed for copper (Cu), iron (Fe), manganese (Mn), zinc (Zn) boron (B) along with selected physico-chemical properties soils. Majority clayey texture (81%), non-saline (80%), alkaline poor organic matter. All adequate AB-DTPA extractable Cu (>0.5 mg kg -1 ), Fe (>4 Mn (>1.8 ) contents. Whereas Zn hot-water soluble B values varied a different way. Sixty six percent low ( 1.5 Zn. Ninety one 1.0 regard B. The data regarding analysis depicted that all high (> 200 whereas 20 19% sufficient (5-20 81% samples. Manganese (40-250 94% (30-39 6% Plant showed 53% (>50), 22% (20-50 25% (18-19 supply. 59% (20-24 41% (25-60 ). relationship between nutrient 2 ” value ranging 0.57–0.81. It is concluded micronutrients fertilization manures may be included program. Further research on wide range sampling strategy area.
