Foliar application of 0.2% FeSO4 + 0.3% ZnSO4 thrice at monthly interval tended to exhibit the highest plant height and spread, number of leaves per plant, average leaf area, number of flowers, fruits, marketable fruits per plant and total yield and marketable yield per plant. These plants also took the least duration to attain the age of flowering as well as harvesting. Micronutrients are vital to the growth of plants, acting as catalyst in promoting various organic reactions taking place within the plant and their deficiencies often limit crop productivity in fruit crops. Iron deficiency in strawberries can occur if soil pH is high and low zinc levels may occur on sandy low organic matter soils. Cool, wet weather enhances iron deficiencies, especially on soils with marginal levels of available iron. Poorly aerated or compact soils also reduce iron uptake by plants (Zehtab-Salmasi et al. 2008). Zinc deficiencies occur more often during cold, wet spring weather and are related to reduced root growth and activity as well as lower microbial activity decreases zinc release from soil organic matter. Zinc uptake by plants decreases with increased soil pH. Uptake of zinc also is adversely affected by high levels of available phosphorus and iron in soils (Mortvedt 2011). Therefore, response of iron and zinc on vegetative and reproductive growth of strawberry (Fragaria × Ananassa Duch.) cv. Chandler was studied in the Division of Fruit Science, Faculty of Agriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, at Udheywalla Campus during 2011-12. The experimental soil was having sand (60.0%), silt (19.0%) and clay (21.0%) and its texture was sandy clay loam. Sixteen treatments, namely 0.1% FeSO4 (T1), 0.2% FeSO4 (T2), 0.3% FeSO4 (T3), 0.2% ZnSO4 (T4), 0.3% ZnSO4 (T5), 0.4% ZnSO4 (T6), 0.1% FeSO4 + 0.2% ZnSO4 (T7), 0.1% FeSO4 + 0.3% ZnSO4 (T8), 0.1% FeSO4 + 0.4% ZnSO4 (T9), 0.2% FeSO4 + 0.2% ZnSO4 (T10), 0.2% FeSO4 + 0.3% ZnSO4 (T11), 0.2% FeSO4 + 0.4% ZnSO4 (T12), 0.3% FeSO4 + 0.2% ZnSO4 (T13), 0.3% FeSO4 + 0.3% ZnSO4 (T14), 0.3% FeSO4 + 0.4% ZnSO4 (T15) and control (spray with distilled water) (T16) replicated thrice were given at monthly interval. The data recorded were statistically analyzed as prescribed by Panse and Sukhatme (2000). The vegetative growth parameters in strawberry cv. Chandler viz., plant height, plant spread, leaf number per plant and leaf area presented in Table 1 significantly increased with iron and zinc sprays. Maximum plant height (17.00 cm), plant spread (38.34 cm), number of leaves per plant (12.78) and leaf area (106.30 cm) were resulted in combined treatment of FeSO4 (0.2%) and ZnSO4 (0.3%) sprays, while minimum plant height (10.14 cm), plant spread (20.62 cm), number of leaves per plant (6.11) and leaf area (35.44 cm) was obtained under distilled water sprays (control). The foliar spray of iron increased plant length, plant spread, number of leaves per plant *Author for correspondence: .
