Abstract
In order to study the effects of biological and chemical fertilizer on quantitative and qualitative yield of forage maize single cross 704 under different levels of Humic acid, an experiment was conducted at the 1393 growing season in the experimental field of the Institute of Agriculture, University of Zabol at a split plot based on randomized complete block with 3 replications. The main plot units and treatments of Humic acid in 3 levels (zero, 6 and 12 liters per ha) were randomized (integrated fertilizer and Biofertilizer) at five levels: A: 100% of the fertilizer recommended (urea, 300 kg + ammonium phosphate, 100 kg + potassium sulfate, 100 kg/ ha), B: 75% of the recommended fertilizer + 2 kg Nano-Biofertilizer,C: 50% of the recommended fertilizer + 2 kg Nano-bio-fertilizer: 25% of the recommended fertilizer + 2 kg Nano bio-fertilizer, E: Nano-Biofertilizer at a rate of 2 kg per hectare were randomized to subplot units. Irrigation and weeding was done on time. After Milky stage plant corn was harvested from the ground quantitative traits (height, stem diameter, fresh and dry forage yield) and qualitative traits (crude protein, digestible dry matter, water soluble carbohydrates, minus the percentage of cell wall hemicellulose, ash and the percentage of neutral detergent insoluble fiber) were measured. In this study integrated fertilizer treatments had a significant impact on the studied traits. So that the greatest impact on plant height, dry matter yield, chlorophyll content, crude protein content obtained from 75% of the recommended fertilizer + 2kg Nano-Biofertilizer with 6 liters per hectare of Humic acid that the plant height and crude protein percentage had the same statistical level with 100% of fertilizer. Forage yield, stem diameter and ASH at 5% were not significant. B treatment with 12 liters of humic acid had the highest percent of fertilizer. Recent age of dry matter digestibility and water soluble carbohydrates had the lowest percentage of acid detergent, insoluble fiber obtained from B treatment with the use of 6 liters of Humic acid and C treatment plus 6 liters of Humic acid had the greatest impact on total insoluble in neutral detergent fiber (NDF). The General results showed that B treatment with 6 liters of humic acid had the greatest impact on quantitative and qualitative yield of corn without a reduction in the consumption of chemical fertilizers 100%.
