Crop rotation and cultural practices on moisture conservation, harvesting and yields of wheat, lentil and chickpea in the rainfed areas of Jordan
1989
Qusous, A.A.
A two year experiment was conducted in Jordan by using the split-split plot design with three and four replications respectively, to evaluate the influence of different crop rotations plus different seedbed preparation and sowing methods on the potential yield of wheat. It also evaluates the influence of different seedbed preparation, sowing and harvesting methods on the yield of lentil and chickpea grain and straw. Total moisture depletion and plant height of both crops were also studied as affected by the different seedbed preparation and sowing methods. An economical evaluation for the production of the three crops was also carried out. The results of the first year experiment indicated that the different crop rotation systems and the different seedbed preparation methods used did cause significant differences in the potential yield of wheat. However, the potential yield of wheat did not differ significantly from each other as a result of employing different sowing methods. The second year results indicated that only the harvesting methods used were the sole reason for any significant differences on the yield of chickpea and lentil grains and straw. The different seedbed preparation and sowing methods did not cause any significant differences in the total moisture depletion nor the plant height of both crops
