| Abstract |
A field experiment was carried out in Noubaria Agricultural Research Station for two seasons ( summer season 2002 using maize and winter season 2002/2003 using wheat), representing calcareous soil, of soil amendments to provide maize and wheat with its needs of nutrients.
The experiment included fifteen fertility treatments. Each treatment was replicated three times. The amendments included rock phosphate, elemental sulphur, rice straw compost and phosphorin (phosphate dissolving bacteria). They added either alone or in combination. The fertility treatments were: control, rock phosphate at rate 2% ( R), 10 ton/fed compost (C1), 15 ton/fed compost (C2), 400kg/fed elemental sulphur (S1), 600kg/fed elemental sulphur (S2), phosphorin (P), C1R, C2R, C1S1, C1S2, C2S1, C2S2, C1P and C2P.
The grain yields, yield components and the chemical analysis of soil and plants for both maize and wheat plants after harvesting were recorded.
Obtained results indicate that application of different soil amendments either individually or in combination, specially elemental sulphur and/or compost, greatly decreased soil pH and EC values and increased soil organic matter content. This reflected on the water soluble of Ca++, Mg++, Na+, Cl--, HCO3- and SO4— and availability of phosphorus as compared to untreated soil plots (control). Application of rock phosphate and phosphorine only and/or combined with compost were superior in greatly enhancing available phosphorus in soil after harvested of maize and wheat and reflected on phosphorus uptake by plants.
The grain weight plant, nutrients uptake by maize and wheat plants and productivity with quality of grains yield were significantly increased as a result of adding soil amendments. On the other hand, the harvest index was not significantly affected by various manurial treatments after maize harvesting, but it was slightly enhanced after wheat harvesting. The results indicated that the application of elemental sulphur individually or in combination with compost was positive effect on properties under the studied as compared to other treatments. General, the application of soil amendments combinations can be successfully used for enhancing the microbial activity as well as the improvement of some soil properties. So, maize and wheat plants will have a better conditions to grow well
