There appears to be renewed interest from growers and the agricultural community in legume break crops to complement canola and cereals in the rotation. For example in the Esperance region a number of farmers bulked up lentil seed in 2016 in anticipation of sowing larger areas in 2017. This paper summarises some of the experiments conducted in 2016 by DAFWA in partnership with the GRDC via the Tactical Break Crop Agronomy Project DAW00227 which supports the growing interest in legume crops.

Some districts in NSW and Victoria are known to frequently develop Sclerotinia stem rot. The purpose of conducting the petal survey was to identify if there are significant differences in the level of petal infestation between districts where the disease develops frequently, compared with those districts where the disease develops once every few years. This information will indicate what influences disease development, background inoculum levels or environmental conditions, or both.

To provide information for the growing farmer interest in subsoil manuring during the year with data and information on demonstration trials on subsoil manuring on heavy clay and duplex soils where the plant available water capacity at depth is restricted by low porosity, water extraction and root growth.

The aim of this trial was to to compare commercial faba bean rhizobia inoculant with new acid tolerant strains from SARDI and the Department of Primary Industries and Regional Development (DPIRD), WA.

To present results from the large plot focus farm trials of the Maintaining profitable farming systems with retained stubble in the Riverine Plains region project, which where to

• investigate, demonstrate and extend cultural practices that will assist growers to adopt no-till stubble retention (NTSR) in medium and higher-rainfall environments;
• build on findings from the previous Riverine Plains Inc. Water Use Efficiency (WUE) project; and
• extend the frontier of agronomic knowledge for crops grown in NTSR systems.

The project seeks to:

• investigate, demonstrate and extend cultural practices that will assist growers to adopt no-till stubble retention (NTSR) in medium and higher-rainfall environments;
