Abstract
A field experiment was carried out during winter season of 2015-2016 in fields of Agronomy department-College Agriculture/ Anbar University (Abu-Gharaib) that located within Longitude 44° East and Latitude 33°North in order to study the effects of four concentrations of Humic acid 0, 1, 2 and 3 cm3 L-1 in growth and yield traits for three cultivars of barely (IPA265, Bohoth244 and IPA99). A randomized complete block design (RCBD) was used according to the arrangement of split plot with three replicates, where the concentrations of Humic acid occupied the main plots while the cultivars occupied the sub plot. The results of the study were summarized as following:
The cultivars were significantly differ in most of growth and yield traits, IPA265, gave the highest average of number of tillers per area unit (m2), flag leaf area, weight of 1000 seed, grain yield 6.05 ton ha-1, while IPA99 gave highest of plant height, number of spikes per area 491.10 spike m-1. Humic acid concentration significantly affected in most of studied traits, the concentration 1 cm3 L-1 gaue highest average of 1000 seed weight and the concentration 2 cm3 L-1 gave highest average of number of seed per spik 46.49, while 3 cm3 L-1 achieved highest average of number of tilleras and grain yield 6.59 ton ha-1. The interaction between Cultivars and Humic acid concentration significantly affected all studied traits except plant height and weight of 1000 seed, However, IPA265 cv. With 2 cm3 L-1 Humic acid gave highest average of flag leaf area 20.38 cm2 and with 1 cm3 L-1 gave highest average of number of seed per spike 50.60 grain, as well as gave with 3 cm3 L-1 highest average of grain yield 7.74 ton ha-1.
