Abstract

Under the use of the new irrigated wheat production method on raised beds in NW Mexico, it is necessary to re-define the components of the traditional production technology, focused on population density (PD) and number of rows per bed (RPB). At the Yaqui Valley Agricultural Experiment Station an experiment was carried out during fall-winter 1991–1992, which consisted of a complete factorial of three plant arrangements: one, two, and three rows per raised bed (RPB), and seven population densities (PD): 20, 40, 80, 160, 240, 320 and 800 thousand plants per hectare (TPPH), in a randomized complete block design with four replications. Results indicated that average wheat grain yields were 730 and 250 kg ha <sup>−1</sup> higher when seeded at two RPB compared with one and three RPB, and PD had no significant effect. At PD higher than 80 TPPH, yields increased consistently. The response to PD was consistent up to around 240 TPPH. Differences in optimum PD were not so large and it is not necessary to change the recommendations when the plant pattern arrangement (RPB) is modified.
