Effect of Organic and Biofertilization on some Qualitative and Productive Traits of Barley Plant

Abstract

A field experiment was conducted in a sandy, clay soil loam in Al-Nahrawan region, east of Baghdad. The experiment included two factors: organic fertilizer (compost) at three levels, 15 tons. ha-1 and 30 tons ha-1 without adding organic fertilizer and biofertilizer (mycorrhiza) at two levels, adding 200 g of mycorrhizal inoculation without addition, In a randomized complete split block design with three replicates in order to evaluate the effect of adding different levels of a type of fungal (mycorrhizal) and organic (compost) bio-fertilizers, individually or in an interaction manner, on the qualitative and productive traits of barley plant (plant height (cm), dry weight (kg. ha-1), grain weight (Mg.ha-1) and harvest index (%) The results showed that the treatment of compost and mycorrhizal interactions was significantly excelled on the control treatment for all traits, with values of (82.13, 9018, 4.117, 38.63), respectively.
