Contribution of Cattle Dung as an Alternative to Mineral Fertilization of Soils in Tomato (Lycopersicom esculenta) Production

The use of chemical fertilizers, which in the long term constitutes a source environmental degradation, has led farmers to organic sources as alternative soil amendments. However, fertilizers alone may not restore fertility highly degraded soils, hence need for integration and mineral fertilizers. objective study was improve tomato productivity. carried out using Fisher block design, with three replicates established on sandy soils. Treatments T0 (control treatment), Tpp (500 kg ha-1of NPK), T1 (40 cattle dung + 167 T2 250 T3 375 T4 500 NPK) T5 NPK dung) were applied elementary plots 20 m2 (5 m x 4 m). Cattle one week before transplanting done. On other hand, split application fertilizer done at start flowering. height plants, circumference collar, diameter fruits, average number fruits weights harvested evaluated plants effective plot. results obtained revealed that addition made it possible reduce quantities commonly used by producers. Thus, treatment kg/ha single contribution basal or ¾ dose producers, agronomic parameters highest yields (16292.25 kg/ha). combination 40 15 is therefore, optimum provide better production.
