Abstract

Study has been carried out in three different environmental areas of Central Highlands in Yemen (Bait Rashed, Wasitah, and Bait Al-Nhmi), during 2013/2014 season. Alfalfa  local cultivar (Koly) was cultivated in three locations of each area. The improved technology package added was: 80 kg/h super phosphate P₂O₅ 48% , 60 kg/h of Urea N 46% and 20 kg/h seed. Whereas the farmer practice was (seed rate of 15 kg/ha and without fertilizing). Randomized Completely Block Design (RCBD) was used with three replications per location. Results revealed that improved technology packages significantly (P≤0.01) enhanced values of: Plant height, tillers per plant, number of days to cut, and forage yield, with the percentage of 87.04%, 85.5%, 8.9%, and 147.4% , respectively over the control. Improved technology package got a high degree evaluation from the farmers in all locations with 66% over the control. Economic analysis showed that the application of improved techniques can make a net return of about 560.316 YR /ha, which reveals an increase of 365.830 YR /ha in revenue compared to the control.

Key words: Technology package, Alfalfa productivity, Climate changes, Revenue, Farmer evaluation, Yemen.
