Work in three experiments according to the design of random sectors with the use of three replications: (T1: 1.5 liters of raw chicken manure, T2: 1.5 liters of improved chicken manure, T3: 2.5 liters of improved chicken manure). We concluded that experiment 3 gave the best results, as it outperformed the experiment. 1 The length of the plant is 15.65%, the number of pods is 38%, the length is 6.9%, the weight of the fruits with peel is 38.8%, the weight of the fruit without peel is 40.5%, and the weight of the vegetative mass is 33.5%. The improved fertilizer also had a positive effect on the properties of the soil, as it led to an increase in organic matter by 31.9% in Experiment 3 compared to Experiment 1 and a reduction in pH estimated by 8.26%, and from here we conclude that the additions played a role in improving soil properties and increasing production, and these additions led To the disappearance of unpleasant odors at the level of chicken waste.Archicken manure, Biochar, peas (Pisum sativum), calcium carbonate, agriculture in oued souf region.زرق الدجاج , الفحم الحيوي , البازلاءMaster
