2019 Barley

This trial was established to determine the impact of planter type on yield of barley, durum, wheat and chickpeas. The crops were planted with a both a Boss double disc and a Janke tyne planter with press wheels on 15/06/19 with 80 kg/ha Granulock Supreme Z. Crop establishment was assessed 16 days after planting and NDVI readings taken 81 days after planting. The trial was harvested 128 days after planting. Yield, EM38, stubble height and ground cover were assessed at this time. Data for EM38, stubble height and groundcover estimate is not presented in this summary. SAGI (Statistics for Australian Grains Industry) analysis found a significant NDVI response in chickpea to plant population, but not for any of the cereal crops. There was a significant overall effect of crop type on NDVI, however the difference between durum and wheat was not significant. SAGI analysis of the data showed there was a significant positive response to establishment in yield for chickpea, but not for any of the cereal crops. There was a significant difference in yield between the disc and tyne sowing types for Barley, but not for any of the other crop types. Planter type had no impact on grain protein and moisture levels in any of the crops tested. However, the low plant populations trended to lower grain protein and higher grain moisture for all cereals. There were no significant differences for the test weight of barley, durum and chickpeas from planter type or plant population. In wheat, test weight appeared to be impacted by low plant populations but not planter type. Stubble height and ground cover was primarily driven by crop, with the cereals having taller stubble and more ground cover than the chickpeas. As expected, the high plant population had more ground cover after harvest than the very low population. Analysis by SAGI found there was a significant overall positive response in groundcover to plant population. There was only a significant difference in ground cover between the two planter types for durum. SAGI analysis found a significant overall negative response in soil water to 1.5m to plant population. There was also a significant mean difference in soil water to 1.5m between cereals and the pulse crop, with chickpea having a higher mean soil water remaining to 1.5m than cereals.
