Abstract: A Field experiment was conducted in the clayey soil of the farm at Sahl El-Hossynia Agric. Res. Station in EL-Sharkia - Governorate, Egypt. The institute farm is located at 31o 8' 12.461" N latitude and 31o 52' 15.496" E longitude. wheat crop (Triticum aestivum L) was planted during winter season (2010-2011) and rice crop (Oryzae sativa) was planted during summer season (2011) to study the effectiveness of cyanobacteria inoculation combined with different sources of soil conditioners to improve soil chemical properties, soil biological activity and reflected to productivity of both wheat and rice crop system; total content of mineral nutrients of both tested plants were taken in consideration.
Results indicated that, in general, applying cyanobacteria inoculation in combined with some soil conditioners decreased slightly pH and EC values, while organic matter (OM) and Saturation Percent (SP) were increased as compared to control treatment. Also, applying cyanobacteria in combined with fulvic acid (FA) and /or humic substances (HS) significantly superior for decrease EC, SAR and ESP values in soil at both studied seasons. Moreover, cyanobacteria inoculation combined with compgypsum increases organic matter (OM) content in soil after two cultivated seasons.
In addition, positive significant responses existed for available N, P and K as well as soil biological activity (total count bacteria, CO2 evolution, dehydrogenase activity and nitrogenase activity) in the studied soils under cultivation with both wheat and rice as a result of applied gypsum combination with cyanobacteria inoculation as compared to control treatment.
On the other hand, wheat and rice yields (straw and grain) along with total content of macronutrients (N, P and K) increased significantly in response to cyanobacteria inoculation in combination with gypsum as compared to other treatments and\or control treatment.
In conclusion, the application of cyanobacteria inoculation combined with humate organic acids helpful to improve the soil properties of saline soils. Also, the cyanobacteria inoculation combined with gypsum improved available and uptake macronutrients reflected that on the yield components.
