| Abstract | ||
| A field experiment of the 2017 agricultural season was carried out usingthe RCBD by three replicates the first factor tested the bio-fertilization using Azotobacter Chroococum, Bacillus Megatherium, Bacillus Circulars, consisting of eight levels (T1, T2, T3, T4, T5, T6, T7 and T8) with three levels of mineral fertilizer (NPK) were added as recommended by the Ministry of Agriculture, with no addition of mineral fertilizers and (F2) A complete recommendation of the samurai that included 40 kg p2o5 / e in a triple superphosphate and 40 k (42% K) and added at planting and 50 kg N / e urea added on two halves at planting and the other half after one month of cultivation in the growth and yield of maize plant CADZ Spanish. The results showed a significant significant effect when adding bio-fertilizers with mineral fertilizers in all studied field attributes. The highest rate of plant height and the number of leaves swallowed (286.2 cm and 16.53 sheets) at T8F2 compared to the comparison treatment in Yaeji site. And the highest rate (9338.1 and 8347.6 cm2) for the Yaeji and Lillan sites respectively. In the chlorophyll ratio, the T8F2 treatment was significantly higher than the mean (57.36 and 55.21%) for Yagi and Lillan respectively. | ||
