| Abstract | ||
| A field experiment of the 2017 agricultural season was carried out using the 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 y maize plant CADZ Spanish. The results showed a significant effect when adding fertilizer The highest value of the number of grains in the cloves and the weight of 500 grains and the grain yield in the unit area were treated with T8F2 interference, which gave a significant increase rate (99.27, 167.74%), (16.11 and 17.57%), And 97.59 and 96.86%, respectively, for Yaiji and Lilian sites. While in the recipe of harvesting, the highest rate of treatment T5F2 was 49.11% compared to the control treatment of the site Yaiji. | ||
