Sowing malting barley in Mid-June to Mid-July was optimum at Lole, Dixis, Goffer and Garadella farms. At these farms, early planting without fertilizer resulted in higher grain yield and lower protein contents than late planting dates. sowing from March 29 to April 8 at Robe and Sinana, and early sowing until Mid-March at Gololcha farm in 'belg' season were optimum for variety Beka, while in 'meher' season sowing early until mid-August was optimum at Sinana farm. Optimum sowing date for malting barley production was around June 25 on red soil and June 15 on black soil at Holetta, Mid-June at Sheno, first week of July at Bekoji and late March to early April (in belg) and early July (in meher) at Sinana. Earlier studies at Holetta suggested that broadcasting 100 to 125 kg ha-1 seed on red soil and drilling 100 kg ha-1 seed on black soil were found optimum rates for large-seeded varieties, while for small-seeded varieties 75 to 100 kg ha-1 seed was optimum on both red and black soils. From seed rate studies conducted by the Arsi Agricultural Development Enterprise at different farms, 100 and 125 kg ha-1 with application of 18 kg N and 20 kg P2O5 ha-1 were recommended for drill and broadcast sowing respectively. Two-cycle cropping sequence experiment on malting barley variety Holkr at Bekoji indicated that the first crop malting barley after faba bean or rapeseed out yielded continuous barley by 37 perecent, while the second crop malting barley after faba bean or rapeseed had 17 perecent yield increment. On vertisols grain yield of malting barley can be substantially increased by improved surface drainage with optimum fertilizer application.
