The effect of humic acid applications on production, production elements and amino acid component of barley plant (Hordeum vulgare L.)

The aim of trial is to determine the effect of increasing dosages (control (0), 3, 6 and 9 lt/ha-1) of humic acid, as a source to provide a biodinamic balance in soil, on barley plant (hordeum vulgare l.) In field conditions, full depend on chance trial design at factorial regulation; the trial was conducted on arpa plant, 4 different humic acid dosage (0, 3, 6 and 9 lt/ ha-1), 3 repeated and totally 12 parcel. According to full depend on chance trial, barley plants were seeded in 3 x 3 m dimensions parcels and 180 kg per ha. In the trial, as material Tokak barley type and a commercial humic acid(HA) named as Base ActosolR (12% HA) were used. In the trial, the soil texture, macro and micro nutrient element amount receivable from soil, chlorophill amount in plant, the obtained stalk and grain yield from plant, the amount of plant nutrients and aminoacid amount in plant texture were determined. Due to trial results, depend on humic acid applications, the soils pH that have barley growth decreased, significantly. In addition to this the beneficial micro elements (P, K, Mg, Fe, Cu, Mn and Zn) amount for plant were decreased. In terms of plant analysis,stalk and grain yield parameters showed increase with 6 lt/ha-1 HA. But the average data shows us 9 lt/ ha-1.In the study it was released that the application dosages need to be very well rated of organic characterized materials as HA in usage of farming fields.
