The effect of using modern technological packages on the productivity and profitability of wheat farms in Iraq.

Abstract

The study was conducted at the field of poultry at the Agricultural Advisory Office , College of Agriculture , University of Basra in (Karmat Ali), where the anaerobic digester of the fixed dome type bioreactor model was designed and installed on site to be exploited, Fresh poultry droppings as raw material for producing liquid organic manure through anaerobic fermentation and taking into account the qualitative characteristics of the maturation of the fermented materials inside the anaerobic digester during periods of Hydraulic Retention Time 0, 2, 4, 6, 8 weeks The averages were compared using the averaged least significant difference (RLSD) at the 5% level.. And the results showed that the periods of Hydraulic Retention at 8 weeks is the period best which the fermented material is decomposed in anaerobic digestion. An organic manure with positive qualitative characteristics in terms of pH 7.02, electrical conductivity EC 17.43 dS m-1organic carbon 318.27 g kg-1 total (nitrogen, phosphorous, potassium) recorded 38.03, 13.70 and 25.25 g kg-1Straight, the ratio of organic carbon to total nitrogen was 8.37, the total solids was 6.80% and The chemical oxygen requirement (COD) 2150 mg L-1.
