In a replicated cutting trial in 2002-03, hay yield was determined in one year old irrigated stands of ‘Super Cuf’ and ‘Cuf101’. Management was as in commercial crops. Cuts were taken on 3 March 2003. Cut material was field dried to approximately 12% moisture before weighing. Mean hay yield of ‘Super Cufl’ was 32% higher than that of ‘Cuf101’. In the same trial in the 2003-04 season ‘Super Cufl’ outyielded ‘Cuf101’ by 21% in the first cut and 24% in the second.
In a comprehensive trial established at Keith in South Australia in 2003, the performances of 28 varieties and elite lines were compared in an irrigated replicated field trial. The highest yielding varieties over three hay cuts in 2003-04 were ‘Super Siriver’ and ‘Super Cuf’ which averaged 2.5 tones/hectare. In this trial ‘Super Cuf’ outyield both ‘Sequel’ and ‘Cuf101’ by 20% (see below).
SuperCuf 2.49 t/ha Sequel 2.06 t/ha Cuf 101 2.08 t/haLSD (5%) 0.27 t/ha.
The above trials indicate the ‘Super Cuf’ is clearly more productive and more pest and disease resistant than its parent varieties ‘Cuf 101’ and ‘Sequel’.
