Abstract in English
The project aims to know and evaluate the effect of replacing part of the mineral fertilizers with organic fertilizers to increase soil fertility.
The experiment carried out in In the fields of the Iraqi Agricultural Research Department - Dabouni Station in (2021) with the treatment groups as follows: Group
(Control, no manure, no fertilizer (T1) Sheep fertilizer, 20 tons ha−1 [SF] (T2) Mineral fertilizer
( N.P.K ) 320 kgN/ha ,100kg P2O5/ha and 120Kg K2O/ha (NPK100%) (T3) Mixture of sheep (20 tons/ha + and mineral fertilizer NPK 320 kgN/ha ,100kg P2O5/ha and 120Kg K2O/ha, 5) Sheep manure + 25%, N.P.K [SMF25%] (T4) Sheep manure+ 50%, N.P.K [SMF50%] (T5)6) Sheep manure + 75%, N.P.K [SMF75%] (T6) Sheep manure +100% N.P.K [SMF100%] (T7)
The experiment laid out in Randomized Complete Block Design (RCBD), with three replications.
The experiment showed that the combination of organic fertilizer and mineral fertilizer [SMF100%](T7) gave significant differences in average of plant length growth (161) cm compared to mineral fertilizer (109) cm and organic fertilizer (99) cm respectively, also (T7) gives significant differences in root length ,ear length leaf area,500 grain weight ,biological yield, Grain yield) and content of organic matter in the soil, but in the same significant of fertilization treatment [SMF75%](T6)
The treatment [Mineral F](T3) gives significant difference in the value of EC (4.2) Dsm-1 and PH (7.5) of the soil Compared to other treatments in the experiment.
