Abstract
A field experiment was carried in Babylon governorate to study the efficiency of spraying nano-kaolinite compare with chelated nano fertilizer in improving growth and yield of wheat under different levels of water stress and according to RCBD, split-plots arrangement. The treatments included the control (without spray) treatment, spray treatments of normal kaolinite solution (K1) and nano (K2), and nano chelated fertilizer (S1). The experimental units were exposed to four water irrigation treatments i.e. regular irrigation, and three levels of water stress (30, 60 and 90% of water needs) represented by B0, B1, B2 and B3, respectively. Spraying treatment with nano kaolinite solution had the highest value of plant height of (98.31cm) under regular irrigation. The highest value of leaf area was achieved after spraying with nano kaolinite (43.01) under 30% of water deficiency. The treatment B2K2S0 gave the highest value of chlorophyll content (66.60 spad). In terms of number of grains in the spike, the treatment B3K2S1 under water deficiency of 90%, gave the highest value (46.80 grains/spike). The treatment B2K1S0 recorded 51.23 cmol/kg of K, while Ca, Mg, P and S achieved the highest values of 12.47, 11.75, 7.00 and 11.28 cmol/kg of the treatments B0K2S0, B2K1S0, B2K1S0 and B1K1S0 respectively. Among the micronutrients, Fe had highest value of 2180 mg/kg with the treatment B2K2S0. As for Zn recorded the highest value of 130 mg/kg with the treatment B1K2S1. All high values of Cu, Mn and Mo were achieved 34.41, 250 and 120 mg/kg with the treatment B1K1S1. The role of the spraying treatments in the foliar feeding and the readiness of the elements for the vegetative and fruiting parts did not discourage the plant from absorbing nutrients from soil solution, and transferring them to up take plant parts through root group, and water stress to which plant was exposed, it’s never be discouraged biological and physiological functions.
