ÉVALUATION DE L’EFFET DE L’APPORT DE FUMIER DE BOVINS ET DE PETITS RUMINANTS ET DU PHOSPHATE NATUREL DE TILEMSI SUR LA PRODUCTIVITÉ DES SOLS ET DES CULTURES DANS LE SAHEL : CAS DE LA RÉGION DE MOPTI

The present study aims to contribute to the fight against the decline of soil fertility and low millet yields in the Mopti region through the application of cattle manure, and small ruminants at different doses and 300kg. ha-1 3 years-1 from PNT. A Fisher block was used in the three agro-ecological zones from 2005 to 2007. The results showed that with the application of 2t.ha-1an-1 of cattle manure and 300kg. ha-1 3 years-1 of PNT obtained an increase in production of millet grain compared with the control of 57.59%, and 52.8% with the application of 5t.ha-13years-1 of cattle manure and 300kg. ha-13 years-1. The contribution of 2t.ha-1an-1 manure of small ruminants and 300kg. ha-1 3 years-1 of PNT allows the increase of grain yield of 60,11% and 63,8% with 5t.ha-13ans -1 manure of small ruminants and 300kg. ha-1 3 years-1 of PNT, compared to the control. Finally, the application of 300kg. ha-1 3 years-1 of PNT allows an increase in grain yield of 0 to 16%. In the second year, soil analyzes showed an increase in the pH value and soil concentration of organic matter and a decrease in the third year. Key words: Small ruminants, cattle, production, soil
