| Abstract | ||
| This experiment was carried out at Kufa technical institute, Al-Najaf governorate on a clay soil to study the effect of incorporating concentrated rice straw with (Ammonia and Protein) using different tillage systems on seed-bed penetration resistance, straw distribution, seedling rate and crop yield under field conditions. The obtained results indicated that conventional and conservation tillage treatments (Conv. S. + Straw, Cons. S. + Straw) were more effective for incorporating the added rice straw stalks into the tested soil. It was found that 43 % and 35 % of the added rice straw were incorporated at depth of 10 – 20 cm when the conventional and conservation tillage were used respectively whereas the remaining rice straw was incorporated randomly at depth 0 – 10 cm in the both tillage systems. The data is also indicated that the conservation tillage treatment with straw (Cons. S. + Straw) gave lower soil penetration than other treatments and the results was closed to minimum tillage. On the other hand it gave from where germination and seedling emergence index has higher total y i e l d c o m p a r e d w i t h o t h e r t i l l a g e t r e a t m e n t s . | ||
