ASSESSMENT OF SOME RECENTLY INTRODUCED BARLEY CULTIVARS IN RESPONSE TO SOIL AND FOLIAR FERTILIZATION

Abstract

Barley can be cultivated and gives better yields in a large number of environments under various fertilization practices. This experiment was conducted in two growing seasons 2018/2019 and 2019/2020 under rainfall condition. Four new introduced cultivars of barley (Arta, Tadmor, Clipper and Furat2) along with two commonly grown cultivars (Local-1 and Local-2) were represented in the current study; Soil (DAP) and foliar fertilization treatments were also involved; the treatments were arranged through Split Plot Design in RCBD with four replications where the seasons considered the main plots, barley genotypes sub plots and fertilization sub-sub plots. The results of the present study demonstrated that each of Arta and Furat2 cultivars performed better in respect to growth and final grain yield under the multi environment conditions of the study. Additionally, the soil application of DAP and foliar fertilization treatment influenced significantly on the yield and growth parameters in various proportions. Application of both DAP and foliar treatments on barley that were grown under the rainfed condition resulted in the highest grain yield, better yield components and most of the growth traits during both growing seasons compared to control treatment. The GGE biplot analysis also showed the alignment of the introduced barley cultivars to the side of DAP and foliar fertilizers for final grain yield and most of yield component parameters demonstrating the importance of both fertilizers and mainly soil (DAP) for enhancing the yield of barley under rainfed environments.
