| Abstract | ||||
| Two field experiments were carried out for two successive seasons of 2004 - 2005 at lsmaiiiia Agric. Res. Station (Agric, Res. Center) to study the effect of organic manure (rice straw compost and chicken manure) application both individually andior both in combination with clay mineral (feldspar) or potassium sulphate applied at two doses (Recommended dose) and 75% of recommended dose of K) on some soil physical and chemical properties and peanut yield under the affect of inoculation with potassium dissolving bacteria. Organic manures were added at the rate of 20m3ffed., while. feldspar and or potassium sulphate was added to the soil at the rate of 50 and 37.5kg K20 fled. Results revealed that the addition of both organic manure alone and! Or combined with feldspar (recommended dose) to the soil decreased bulk density and increased total porosity at both growing seasons compared to the soil without organic manure or feldspar. Application of chicken manure mixed with feldspar (at rate 100%) and inoculated with Bediius pasteun'r‘ increased significantly the available N. P and K contents in the soil as compared to the control treatment (without inoculation). Results demonstrated significant increases of peanut yield for both seasons due to the addition of either rice straw compost or chicken manure to the soil mixed with feldspar and inoculated with Becflius pasteuni' and followed by potassium suiphate fertilizer. The lowest value of peanut yield was obtained with rice straw compost without bacteria inoculation and potassium mineral fertilizer. Also, results showed thatti, P and k content of both straw and grains "along with oil content increased due to the addition of organic manure combined with feldspar and inoculated with bacteria than those obtained by without inoculation treatments. In conclusion. it is of worth to note that the addition of organic manure combined with feldspar at 100% of full recommended dose and soil inoculation with BacriIus pasteuni led to decrease soil bulk density and increase total porosity as well as improve the nutritional status and increase yield of peanut plants grown on sandy soil under drip irrigation system. | ||||
