2016 Lentil in Esperance region 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.

Can agronomy overcome yield penalty of retained (F2) hybrid TT canola in the low rainfall zone? To investigate whether agronomy can overcome the yield penalty of retained (F2) TT hybrid canola compared with purchased (F1) hybrid seed by using; seed mixes. increased density or, grading to increase seed size.

Nitrogen management of hybrid and open-pollinated canola in the WA low rainfall mallee To investigate the nitrogen rate and time of application response of canola varieties to yield and oil content of TT and RR hybrids in comparison with open-pollinated types to: 1. Provide growers in lower rainfall environments with guidelines on optimal nitrogen rates and times of application to maximise grain and oil yields. 2. Determine if the management of hybrid canola nutrition is different to that of open pollinated varieties due to different responses to N rates and timing.

Plant density in low rainfall canola To investigate the plant density response to yield and oil content of TT and RR hybrid canola in comparison with open-pollinated canola.	Department of Agriculture and Food WA GRDC	2013	Grass Patch WA

Retained canola seed options- Grading Harder, buying new seed, upping seed rate, mixes or living with To investigate if retained open pollinated seed which is smaller than commercially available seed is less productive than new seed, and if grading or increasing seed rates can compensate.

Retaining canola seed To determine if retaining canola seed leads to reduced yield, oil and financial return.	Department of Agriculture and Food WA GRDC	2016	Grass Patch WA

Summary of timing and rate of N for lower rainfall canola Assess the response of canola to N and to determine if the timing of N could be delayed in WA until later in the growing season	Department of Agriculture and Food WA GRDC	2014	Grass Patch WA
Research organisaton
Timing of nitrogen in low rainfall canola To investigate the response to changing the nitrogen rate and changing the time of application. Canola yield and oil will be measured and RR hybrids will be compared with open-pollinated TT types (OP TT).	Department of Agriculture and Food WA GRDC	2013	Grass Patch WA
