Yield trends high­lighted

FIN­LEY group dis­cus­sion meet­ings at­tracted 75 farm­ers cov­er­ing plan­ning for rice and tim­ing of wa­ter­ing for wheat and canola re­cently.

Group fa­cil­i­ta­tor John Lacy said farm­ers learnt a lot from the 52 Ricecheck crop records re­port from the 2010/11 sea­son, which will as­sist them im­prove prac­tices for the 2011 sow­ing sea­son.

They said it was great to see how their prac­tices com­pared to the prac­tices of other farm­ers and learn from other farm­ers.

The 10 top yield­ing rice crops av­er­aged 12t/ha.

Sow­ing on time, good es­tab­lish­ment and weed con­trol and ap­pli­ca­tion of a min­i­mum of 180-200kg urea/ha be­fore per­ma­nent water were a fea­ture of the top 10 yield­ing crops.

Nine of the top 10 were top­dressed with urea at pan­i­cle ini­ti­a­tion.

There were no sow­ing method yield trends with aerial pregermi­na­tion, dry broad­cast and drill sow­ing all rep­re­sented. Sim­i­larly there were no va­ri­ety yield trends.

The av­er­age yield for the 52 crops was 10.4t/ha in­di­cat­ing the 2011 har­vest was a good sea­son.

The av­er­age water use was 14.4 ML/ha with ir­ri­ga­tion mak­ing up 10.1 ML/ha and rain­fall mak­ing up 4.3ML/ha.

This re­sulted in a water pro­duc­tiv­ity of 0.7t/ML which is the tar­get for the East Murray Val­ley.

The av­er­age sow­ing rate was 159kg/ha.

The av­er­age preper­ma­nent water urea rate was 194kg urea/ha which is close to the min­i­mum rate rec­om­men­da­tion by NSW DPI Re­searcher Brian Dunn.

Mr Lacy said with one year’s ex­pe­ri­ence grow­ing rice again farm­ers were plan­ning 200-250kg urea/ha urea rates.

On rice stub­bles they were go­ing to ap­ply an ex­tra 50-80 urea kg/ha. Phos­pho­rus was ap­plied to 27 per cent of the crops with lower P lev­els.

Mr Lacy was dis­ap­pointed the tim­ing of spring wa­ter­ing of wheat and par­tic­u­larly of canola was late.

One G Dot soil mois­ture me­ter read­ing in­di­cated the crop was ready to water 10 days ear­lier.

Soil auger­ing was dif­fi­cult at both the Garry Seamer and Ian Bryce crops.

Farm­ers seemed to have for­got­ten the three years re­sults from the Lo­gie Brae Land­care project.

The re­sults showed for top wa­ter­ing re­sponses with canola it needed wa­ter­ing at the start of flow­er­ing, not at mid flow­er­ing as farm­ers were pre­par­ing to do this sea­son.

Mr Lacy added that although he was now an agri­cul­tural con­sul­tant he was happy run­ning the groups as a com­mu­nity ser­vice and at min­i­mum cost to farm­ers and could be con­tacted on john­mar­[email protected]­mail.com or phone 0427 311 821.
