MERREDIN INTRODUCTION Most of the field work was aimed at extending our knowledge of where responses to seed inoculation might be obtained in Western Australia. In some experiments this aim was combined with that of ascertaining the extent of the soils on which lupins responded to soil applications of cobalt (jointly with Mr J.W. Gartrell). Unfortunately, many trials were compromised by inadequate nodulation of the plants by the inoculant rhizobia. This was why the two trials examining the effect of drilled fertilizer on nodulation (75M028, 29 were repeated with late sowings at Wandering (75NA32,33). Only one of the six cobalt experiments (the one at Lancelin) showed a response to cobalt. This may mean that Lancelin is indeed the only area low enough in cobalt to give a response. Also, there may have been differences in seed quality (cobalt cotitent of seed). Note that the seed used in the very responsive 1973 and 1974 trials came from the West Midlands and had very low cobalt levels (in the order of
