EFFECT OF INTRA ROW-SPACING ON MALT BARELY VARIETIES (HORDEUM VULGARE L) ON YIELD PERFORMANCE AT GITILO RESEARCH SITE AND JARTE WERDAS FARMERS? FIELD, WESTERN ETHIOPIA.

Malt barely is one of the cereal crops that are dominantly cultivated for beer beverage or beer factors. So that farmers in high land area of Ethiopia is mainly produce as cash crop. While the production of malt barely crops are still not fit the requirement of malt factors due to certain agronomical problems like space between plant, agro ecological requirement of the crops and lack of improved varieties of the crops are the major challenges for malt barley production in the country. The research work was conducted at Gitilo research site and Jarte Farmers field of Western Oromia Regions state to determine the appropriate intra-row spacing for malt barely varieties at the study areas and to evaluate the growth and productivity of malt barely varieties at the study site. The experimental material to be used Ibon, Bahite and Holker varieties of malt barely was obtained from Kulumisa Agricultural research center. The seed was sown at 10cm, 15cm, 20cm and 25cm intra row spacing at both study site and the field lay out was arranged as Randomized Complete block design with three replication. The experimental procedures likes land preparation, sowing, weeding, fertilizer application, harvesting and threshing was done uniformly at appropriate time under field condition. The phonological, growth and yield data data?s were collected from the field at a time and the collected dates were analyzed by statically procedures SAS 9.1 version soft ware and the treatment mean was separated at 0.05% probability level. The analysis of variance was significant effect on the phonological and growth parameters while the yield parameters were non-significant difference on malt barley crop. The analysis of variance on location, varieties and interaction effect were shown significant difference (p<0.05) on grain yield. But the main effect of intra row spacing was significantly difference (P<0.01) on grain yield of malt barely crop. The highest grain yield 33.6qu/ha was measured at 10cm intra row spacing on Ibon variety of malt barely at Gitilo site. But the lowest grain yield 25cm was measured at intra row spacing of Bahite variety of malt barely at Jarte study site. Moreover at narrow plant spacing high amount of malt barely productions was registered at Gitilo study site. Therefore at 10cm intra row spacing Ibon variety of malt barley is more recommendable at gitilo study site.
