| Abstract | ||||
| A field experiment was conducted in 2002/2003 season at the farm of EI- Serw experimental station (ARC), Domiatta governorate, Egypt. This study aims to assessment the effect of potassium fertilization (0, 24 and 48 Kg K20/fed) and soil amendments (Gypsum at rate of 6 ton/fed, FYM at rate of 20m3/fed. and Gypsum + FYM) on wheat plants irrigated with Nile and drainage water. The obtained data revealed that: Wheat grains yield; 1000 grains weight and straw yield significantly decreased under irrigation with drainage water, but increasing the dose of K-fertilizer significantly increased them. On the other hand, application the amendments of Gypsum (at rate 6 ton/fed) or FYM (at rate 20 m3 /fed) either solo or in a mixture of Gypsum (6 ton/fed) + FYM (20 m3 /fed) gave significant increments in the yield components compared with the control (no-amendment). In general, the mixture of Gypsum + FYM was the more beneficial treatment on yield components, and was distinct under irrigation with Nile water . Irrigation with Nile water was more effective on increasing N, P and K uptake (kg/fed) by grains and straw of wheat than the irrigation with drainage water. While non- significant differences were noticed between the irrigation with the two types of waters on N%, P% and K% of wheat straw. Increasing the dose of potassium fertilizer, in general, significantly increased N%, P%, K% and their uptake (kg/fed.) by grains and straw of wheat comparing with the control treatment (KO) under the conditions of irrigation with Nile or irrigation with drainage water. N, P, and K (percent) or (kg/fed.) of wheat grains and straw tended to increase significantly because of treating the soil with any of gypsum or FYM, a mixture of gypsum + FYM in comparing with the un-treating soil (control) under the conditions of irrigation with Nile or with drainage water. The superiority in these increments was noticed for the treatment of (gypsum + FYM) followed, in general, with the treatment of FYM, then the treatment of gypsum. | ||||
