Description
During bloom, lucerne (Medicago sativa L.) was subjected to different irrigation frequencies based on accumulated Class A 1 Pan evaporation (Epan) to determine the 1 irrigation requirements on a shallow duplex soil. Seed yields ranged from 528 kg ha- on the driest treatment to 1105 kg ha- on the treatment irrigated on the lowest Epan interval. The components of yield which correlated with seed yield were top growth, number of sterns, number of racemes with pods,.and the number of seeds per pod. In order to produce high seed yields, lucerne has a high requirement for water during bloom and on shallow soils most of the crops water requirements must be applied during bloom. An Epan interval of 75 mm was found to be most productive, however, a shorter Epan interval may be necessary for shallow soils which are more difficult to wet.
