Abstract
A pot experiment was conducted at the field of Agricultural and Biological Researches Office in season 2006 - 2007, the treatments consisted of three nitrogenous fertilizers (i.e. Ammonium sulphate, Urea, Sulphur coated urea (SCU) and control), Two levels of zinc (0 and 5 mg Kg-1) as ZnSO4.7H2O was applied in two soils (silty clay and loamy sand). The objective of this study was to study the interaction effect addition of some nitrogenous and zinc fertilizers on yield, N and Zn uptake of wheat. A factorial experiment was used (4 X 2 X 2) in a randomized complete block design with three replicates. The results revealed that straw, grain, total dry matter yield, N and Zn uptake of wheat were significantly increased with N fertilizers addition in both soils. Sulfur coated urea gave higher value for all plant parameters as compared with other two fertilizers. Also the results confirmed that N fertilizers with zinc sulphate ( 5 mg Kg-1) addition in both soils significantly increased straw, grain , total dry matter yield , N and Zn uptake by 30 , 24 , 33, 29 and 60% respectively as compared with control (0Zn). The highest values of all plant parameters were obtained from interaction between sulfur coated urea and zinc applied was 26.82 , 14.05 , 40.91 gm pot-1 for straw , grain and total dry matter yield respectively, Also 707.2 mg pot-1 and 647.9 ug pot-1 for N and Zn uptake of wheat. Silty clay soil gave significantly higher values for all plant parameters as compared with sandy loam soil.
