[Effect of some cultural treatments on yield of wheat and barley in the dry areas in the northern part of Jordan]
1987
Ghribeh, A.N.
A field trail under rainfed area (250 mm) was conducted in Remtha 1983/84 and 1984/85 seasons. Two kinds of plows (Chisel and Moldboard), crop rotation (crop-crop; fallow-crop) and three levels of phosphorus fertilization (0, 40, 80 kg P2O5/ha) were used with wheat and barley. Split block design with four replicates was used. Significant differences between barley and wheat in yield and plant characters were recorded. Barley was superior to wheat in yield and plant characters were recorded. Barley was superior to wheat in the various traits in both seasons. Chisel plow excelled moldboard in yield and yield components in both crops. Chiselling increased grain, straw and total wheat yields by an increase of 5.3%, 15% and 12% in the first season, whereas these increments reached 8.3%, 8.5% and 8.6% in the second season. Concerning barley, the increments of grain, straw and total yield were 6.5%, 8.4% and 7.6%, respectively due to the use of chisel in comparison to moldboard in the first season, while increases in the second season were 9%, 10.9% and 9.8% in the respective order. Another field trial under rainfed conditions in Maru was carried out in 84/85 and 85/86 seasons. Three levels of P205 (0.40 and 80 kg/ha) and three levels of N (0.30 and 60 kg/ha) were applied to wheat and barley. Randomized complete block design was used in three replicates. Yield and plant characters of barley excelled those of wheat. The application of P2O5 led to an increase in yield and yield components of wheat and barley. However insignificant differences in the various traits between 40-80 kg P2O5 were observed, the application of 40 kg could be considered optimal. Increasing the level of N, increased grain, straw and total yields of both crops in both seasons
