Abstract |
: |
This study was conducted at the Agricultural Research Station at Hada Al-Sham University of King Abdulaziz University during the period 2015-2016 and 2016-2017 to study the effect of using different rates of manure, different kinds of animal fertilizers, chemical fertilizers, nitrogen (N) and phosphorus (P) , and potassium (K) on the productivity and quality of hybrid maize and on the grain content of oil and protein as well as the chemical soil properties in splits plot design. Three concentrations of humic acid (zero, 50 and 100 liters / ha) and three types of animal fertilizers plus mineral fertilizer NPK (20:20:20) rate 600 kg / ha were used . The yield, grain yield, corn grain content of oil and protein as well as soil chemical properties were estimated after season 2. The results showed that the concentration of humic acid 100L/ha the highest averages of the characters (plant length, cob length, cob fresh weight, weight of seeds per cob) (Weight of 100 seeds, weight of cob t/ha , grain weight / ton/ ha), as well as grain content of oil and protein compared with 50 L / ha and without humic acid . And fertilization with the chemical fertilizer (NPK) exceeded the other organic fertilizers significantly, giving the highest qualities in the yield components of the crop as well as the grain content of oil and protein. In the case of the organic fertilizers the chickens manure has exceeded followed by sheep fertilizer and then comes the cow manure fertilizer. As for the effect of the interaction between humic acid and fertilizer type, the concentration 100 L / ha of humic acid with the chemical fertilizers gave the highest averages, followed by the chicken manure, followed by sheep fertilizer and then the cow manure respectively. As for the soil content of the major elements (N, P, K) , the organic matter, and the value of pH and EC, the highest means of these characteristics were obtained under the fertilization with humic acid at concentration of 100 L / ha followed by the concentration of 50 L / ha and zero humic acid except soil pH where it was the lowest at 100 L / ha and highest at zero humic acid . |
