| Abstract | ||||
| Two field experiments were carried out for two seasons 2004 and 2005 at Ismailia Agric. Res. Station to study the effect of organic manure with application of natural mineral on some physical properties of soil (Bulk density, field capacity and available water) and chemical properties of soil (pH, EC and available of macronutrients). Macronutrient contents of both tomato and pea plants and productivity were studied. The experiments were designed in a split-split design with three replications. Two forms of organic manure (Farmyard manure and chicken manure) and tow rates of natural mineral (bentonite and feldspar in combination with rock phosphate) in presence of biofertilizers (a mixture of Azotobacter Chroccoum, Bacillus Megatherium namely (phosphatek) and Bacillus Pasteuril namely (Biopotash). Data indicate that application of natural minerals and organic manure decreased the values of soil bulk density, soil reaction (pH) and E.C, in spite of increased the macronutrient availability ¡n soil. The soil bulk density was inferior at application of FYM ¡n combination with 100% of bentonite ÷ rock phosphate, an opposite trend being obtained for soil moisture, pH and E.C values. Data showed high significant increases in available N and P due to the application of FYM ¡n combination with 75% of bentonite + rock phosphate, in spite of the significant highest values of K available in soil obtained with FYM in combined with 75% of feldspar + rock phosphate. With regarding the inoculation with bacteria, data had recorded lowest the bulk density, pH and E.C values but highest the field capacity, available water and macronutrients availability in soil. N, P and K contents in studied plant parts as well as yield components for both tomato and pea plants generally increased with application of organic manure and natural minerals. In addition, obtained results indictd that pplied FYM in combination with low rate (75%) of bentonite ÷ rock phosphate recorded high values of macronutrient contents and yield components of two studied plants. | ||||
