Abstract: The toxic effect of Lead on plant is a depended on concentration of Pb, type of soil, soil properties, plant species and organic manure. A present study was aims to bring out the effect of different levels of Lead and FYM on yield, nutrient content and uptake by fodder maize grown in two texturally different soils of Gujarat state. This experiment was carried out in pot-house at the Department of Soil science and Agril. Chemistry, B.A. College of Agriculture, AAU, Anand during summer season of 2013. The Treatments were comprised of five level of Pb (0, 5, 10 20 and 40 ppm) applied as Pb (NO3)2, two levels of FYM (0 and 10 t ha-1) and two texturally different soils were loamy sand (Typic ustrochrepts) and clayey soils (Typic chromusterts) of Gujarat. For this, the loamy sand and clayey soils were collected from Anand and Karvan village of dabhoi taluka of Gujarat, respectively. The results indicated that the application of Pb significantly reduced the dry matter yield of shoot (65.15 to 36.69 g pot-1) and root (7.34 to 4.01 g pot-1) of maize. The highest dry matter yield of shoot (65.15 g pot-1) and root (7.34 g pot-1) were obtained in treatment T16 (Pb0+FYM10+Clayey soil). Result also revealed that with increasing doses of Pb, the nutrients content (N: 2.58 to 1.96, P: 0.180 to 0.140 and K: 0.785 to 0.640 % in shoot; N: 1.75 to 1.19, P: 0.778 to 0.669 and K: 0.642 to 0.450 % in root) were found significantly decreased. A nutrients uptake by plant parts were also reduced when Pb concentration was increased due to Lead toxicity might be occurred on the plants, whereas application of FYM inhibited toxicity of Pb and supported to surplus the yield as well as nutrient content and uptake but reducing trend were remain same as per dose of Pb increased. A FYM application @ 10 t ha-1 gave significantly higher yield and nutrient content as compared to no FYM treated pot. Besides this clayey soil produced higher yield, nutrient content and uptake as compared to loamy sand soil because of clayey soil have a more clay particles which have a fixed Pb and reduced availability of Pb in soil.
