Abstract

Trial 87M71

Effect of row spacing and stubble retention on the yield of wheat.

Location: Merredin Research Station.

Treatments, site management and results from 1987, 1988 and 1989 have been described in previous experimental summaries. Four row spacings (9, 18, 27 and 36 cm) are compared in either burnt or stubble retained plots, on a red brown earth on the Merredin Research Station. There are six replicates laid out in a randomised block design.

Trial 90ME32

Effect of row spacing and variety on the yield of wheat.

Location: duplex site at Crooks (see 1989 Experimental Summary)

This trial was carried out on the duplex soil site at Crooks (see 1989 Experimental Summary); in 1990, the wheat crop was sown after lupins, and aimed to look at the interaction between row spacing and variety of wheat. Varieties which differ in their canopy characteristics might be expected to differ in the rate at which they develop ground cover, and might therefore influence the partitioning of ET between soil evaporation and crop transpiration. The varieties Kuhn (low tillering, small leaf area) and Aroona (higher tillering, larger leaf area) were compared at row spacings of 9, 18 and 36 cm.
