Use of topdressed CAN in wheat locations
Aims

To establish the fit for calcium ammonium nitrate (CAN) as a topdressed fertiliser in wheat in a low rainfall situation and on an N responsive site.

Key messages

CAN gave a significant yield result at both timings and over both rates of urea (Table 1). The site responded to topdressed N markedly with a yield increase of 0.81 t/ha (90 Urea) to 0.93 t/ha (132 CAN) at the first timing. The second timing showed a 0.6 t/ha (132 Urea) to 0.82 t/ha (132 CAN) yield response. Both CAN responses were significantly different to Urea. The first timing gave a higher yield response with both products. There was little site variation with both controls not significantly different.
