Effect of Biofertilizer and Humic, Fulvic Acid Application on Growth and Productivity Corn Plant Zea mays L.

Abstract

A field experiment was conducted in Agric. College, Univ. of Muthanna to study the effect of biofertilizer Humic rates 0, 10, and 20 l. ha-1, falvic acid rates 0, 2, and 4 ml l. ha-1 applications and their interaction on growth and productivity of biofertilizer B0 control, and B1 inoculated seed corn with Bacillus, during the growing season of 2015. All experiment units received 240 kg N ha-1, 80 kg p ha-1 and 120 kg K ha-1 in two doses during the plant growth. Application of biofertilizer and humic, fulvic acid on plant and soil and their interaction significantly increased plant height, content chlorophyll and dry matter weight. The highest results were accompanied to interaction of these three factors (biofertilizer, Humic, falvic acid of foliar and Humic, falvic acid added to soil. The highest dry matter and grain yield of corn were obtained at treatment from B1F2S1 10.6Meg ha-1, 7.276Meg ha-1, respectively. The B1 biofertilizer (Bacillus bacteria) was more effective than B0 (without inoculation) on most of variables of studied corn parameters. Inoculating corn seed resulted in significantly increases in plant height, chlorophyll content, dry matter weight and grain yield with an increment 8.5, 6.7, 27.51, 8.94 %, respectively.
