| Abstract | ||||
| A field experiment was carried out in loamy sand of Isimailia Agricultural Research Station (ARC) during winter season 2010- 2011. Wheat plants (Triticum aestivum L.), Giza 168 variety were sown. The used treatments were include two factors, (A) three levels of soil moisture regime; 75%(W1), 60%(W2) and 45%(W3) of field capacity); (B) five organic treatments (chicken manure) and mineral (ammonium sulfate) nitrogen rates; (control (T1), 120 kg N ChK (T2), 65 kg N ChK + 55kg N mineral (T3), 50 kg N ChK+70 kg N mineral (T4), 35 kg N Chk+85 kg N mineral (T5). The experiment design as randomized complete block design for factor A with B split plot on A in three replicates. After harvest, grain and straw yield were recorded, NPK uptake of the grain and straw, soil properties (Bd, VR, TP, HC, Pores and moisture constant) were determined. The results were summarized as follow; Data revealed that effect of moisture regime W1, W2 and W3 were insignificant on soil physical properties. Significantly changes in bulk density and soil porosity due to the use of different application rates of both chicken manure and inorganic fertilizers as ammonium sulfate, where BD decreased and VR and TP increased with nitrogen rates. Relative decreased in QDP and FCP while increasing SDP and WHP for T2, T3, T4 and T5 compared to control. Hydraulic conductivity significantly decreased by applying chicken manure. The maximum decreases were 35.41, 21.12, 23.40 and 11.05 for T2, T3, T4 and T5 respectively. Also, WHC, FC and AW increased, while WP decreased with the previous treatments compared to control. Soil moisture regime of W1 and W3 at the root zoon resulted in a significant decrease and W2 increased on yield of wheat grain and straw. Regardless the effect of nitrogen level, decreasing the moisture content in the root zone decreasing the grain and straw of wheat yield and the values could be arranged in descending order as follows W1>W2>W3 for grain, and W2.>W1>W3 for straw. The maximum and minimum values of wheat grain and straw yield were 3.211, 0.487, at (T4W2), (T1W3) for grain yield 5.099, 0.952 ton/fed after, (T4W2) and (T1W3) for straw. Soil moisture regime of W2 as well as T4 was the highest effect on N-uptake of grain and straw. Nitrogen treatments increased N uptake in both grain and straw. It could arrange the mean values of N-uptake in descending order as T4 > T5> T3 for both grain and straw. Soil moisture regime of W1 for grain and W2 for straw as well as T4 for both were the highest effect of P-uptake in the grain and straw. Increase inorganic-N increased K–uptake in both grain and straw. It could arrange the mean values on descending order as follows T4 > T3> T5 respectively. The same trend was observed in case of the effect of water regime on the K uptake. Water regime treatment of W2 and nitrogen treatments of T4 have pronounced on the K–uptake in grain and straw. | ||||
