| A field experiment is carried out in one of the farmers' fields in the north-east of Ramadi District area in Anbar Province during growth season 2012 -2013 in a Silty Loam texture soil, to study the effect of time and the level of agricultural sulfur application on the uptake of ( phosphorus, iron, Zinc ) in plant and the growth of two genotypes of maize plant Zea mays L. (genotypes 5012 and genotypes 106). The agricultural sulfur produced locally in Mishraq fields (95% S) in two levels ( 0 , 2500 ) Kg.ha-1 on fure time ( applied when agriculture, applied a month later of planting, applied two months later of planting, applied three months of planting) , nitrogen is at a rate of 320 kg.ha-1 using urea (46% N) phosphorus is added at a rate of 100 kg P.ha-1 using the fertilizer DAP (21% P) and potassium is added at a rate of 180 kg K.ha-1 using potassium sulfate (41.5 % K) , according to a global experience within the randomized complete block design (RCBD) and three replicates. The results show a significant increase in genotypes 106 other than genotypes 5012 in the uptake of (phosphorus, iron and zinc)and in the plant and (dry weight of shoots, the number of grains per head and yield) when agricultural sulfur is applied to the soil, and treatment of agricultural sulfur two months later of planting (T3) also give a significant increase in indicators as compared to treatment (T1), which give the lowest values, the treatment of agricultural sulfur application is higher than control where it gave the highest average of grain yield to 6.15 T.ha-1,in an increase of 23.74% compared with the control treatment, application of agricultural sulfur gave a significant effect on grain yield as T3 treatment achieved a higher yield of 6.63 T.ha-1 in an increase of 17.13% as compared with treatment T1, which give less yield of grain of 5.66 T.ha-1. | ||
