Winter malting barley production on heavy soil 'Non-malting' sites

Abstract

The main objective of this project was to identify factors contributing to the reliability of production and the optimum management of winter malting barley on heavy land. The trial was over three cropping years for the harvests of 1991, 1992 and 1993. Two winter barley malting varieties, Pipkin and Puffin were grown at 4 nitrogen rates (0, 80, 120 and 160 kg ha-1 N) and, under 4 plant growth regulator regimes(PGR), (1) Nil, (2) chlormequat only [as New 5-C Cycocel], (3) 2-chloroethyl phosphoric acid only [as Terpal], and (4) a sequence of (2) and (3). In each year the trial was done at four heavier soil sites and one light land site.
