| Abstract | ||||
| A field experiment was carried out during two successive growing seasons of 2007/2008 and 2008/2009 on a sandy soil at South Tahrir Province, Agricultural Research Station, Agricultural Research Center, Ali Mubarak Village, El-Bostan Region, El-Behiera Governorate, Egypt under a cropping-sequence of sesame-wheat to evaluate the management proper of supplying N-organic manures, i.e., composted rice straw and chicken manure wastes, besides N-mineral fertilizer, with special reference to the associated amelioration in soil physio-chemical, fertility status and productivity of the grown plants. The experiment was setup in a randomized complete block design with three replicates. Ten treatments were examined, i.e., control, 100% of N-organic released from either chicken or composted rice straw, 100% of the recommended of N-mineral dose as ammonium sulphate as well as mixture ratios of N-organic : N-mineral of 3:1, 1:1 and 1:3. The application of N-rates of all fertilized plots were kept at 45 kg N/fed for sesame crop at summer season and 100 kg N/fed for wheat at winter one. The obtained results showed that application of either composted rice straw or chicken manure as solely or combined with N-mineral fertilizer significantly improved the physical properties of the studied sandy soil, i.e. bulk density, hydraulic conductivity, infiltration rate, penetration soil resistance and soil moisture constants (field capacity, welting point and available water content). Also, incorporation of both N-mineral and Norganic sources caused substantial increases in soil available N, P, K, Fe, Mn, Zn and Cu. Organic matter content in soil was also increased gradually with increasing the portion of applied N-organic sources in a mixture. Grain and straw yields of sesame and wheat were progressively increased with raising the applied N-organic portion in the N-mixture sources. Also, N, P and K uptake by both grain and straw followed a trend almost similar to that crop yields. Seed oil content and oil yield of sesame were positively affected by the solely or combined treatments of N-organic and N-mineral. Moreover, a pronounced increase in crude protein content of wheat grain was followed a trend similar as mentioned before. These results are emphasized the importance of partial replacement of N-mineral fertilizers by the use of organic ones. However, applied chicken manure was recorded a better effect as composted to the other treatments for ameliorating soil physico-chemical properties and fertility status as well as its productivity for the grown crops under the prevailing experimental conditions. | ||||
