Due to the severe drought, conventional planted field was not harvested, while the other field yielded 700 kg/ha even it was planted after wheat which had less residual moisture than fallow
2.5 t/ha wheat yield is obtained from 0 till planting. Spring plantings (lentil, sunflower, safflower ) were outstanding.
