To achieve self-sufficiency for oil crops in Egypt. It needs a management as apply tillage practices with organic waste. So, an experiment was conducted at the Agricultural Research Station in Noubaria. It was planted with sunflower seeds, Sakha 53 summer 2021, followed by planting canola, Serw4 winter season. To study the effect of two different tillage practices, with applying of organic waste alone or mixed with compost on the productivity of calcareous soil and sunflower and canola crops. Results showed that: applying different tillage methods and organic waste had significant effects on ECe, pH, and OM values and the availability of N, P, K, Zn, and Fe mg kg-1 values in calcareous soil.

Moreover, tillage methods had significant effects on the availability of Zn and Fe mg kg-1 values. Data revealed that seed yield (kg ha-1), Oil % of sunflower and canola crops, P, K, Zn, and Fe contents were significantly affected by deep tillage higher than surface tillage. Also, by applying organic treatments. Tillage methods had a significant effect on Oil % in the canola crop and Zn and Fe (kg ha-1) values content of both crops.

The agronomic efficiency (kg kg-1) and recovery of N, P, and K % in seed yield of sunflower and canola crops were increased significantly by applying both tillage practices. Also, the same trend was noticed for both the agronomic efficiency and recovery of N, P, and K % in both crops. Investment ratio values increased due to applying organic waste low value.
