Abstract

A field experiment was carried out at the field station of the village of Bounouara in Constantine, Algeria, during the agricultural seasons 2016/2017 and 2017/2018, with the aim of studying the impact of four agricultural dates (14th November, 1st December, 2nd January and 17th January). Seven soft wheat varieties (Plateaus, Cedar, Ein ebeid, Arhamocho, Tides, Masin and Pomerzov), according to the design of split plot with three replicates. The results showed that agricultural traits had a significant effect on the phenological stages, plants height and grain yield and its components. The results showed that the decrease in blooming stage in a percentage of 22.52% led to a decrement in plant height (20.81%), number of spikelet (14.02%), number of kernels (12.53%), 1000 kernel weight (10.92%) and grain yield (69.96%). The varieties differed within each other, where the variety Plateaus was the most adaptability and stability one in Bounouara with a grain yield of 4456 Kg/ha. The study recommends taking into consideration the life cycle of wheat varieties when grown, where at the early dates the long-life wheat varieties should be sown, and vice versa.

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.
