The effect of raised bed planting on irrigated wheat yield as influenced by variety and row spacing

By: Contributor(s): Material type: TextTextLanguage: English Series: ACIAR Proceedings ; No. 121Publication details: Canberra (Australia) : ACIAR, 2005.Description: 11 pagesISBN:

Subject(s): In: Evaluation and performance of permanent raised bed cropping systems in Asia, Australia and Mexico p. 1-11634079Summary: Experiments were conducted under full irrigation and high fertility in northwestern Mexico during the period 1988 to 2005 to study the response of a range of current cultivars of bread and durum wheat and of triticale to raised bed planting. Results suggested that in this environment the main consideration was the ability of the cultivar to capture the solar radiation falling in the gap between the beds, and that the common gap of 44 cm could be compensated for in most cultivars, but not all. Those losing 10% of yield with such a gap tended to be short cultivars, as in two-gene dwarf bread wheat varieties. There was good evidence that varieties and advanced lines released after the late 1980s showed no yield loss with such a gap, and some could tolerate an even larger gap (up to 55 cm). The results, which, it is stressed, apply to favourable lowlatitude wheat growing conditions like those of northwestern Mexico, are discussed in depth.
