Whilst no in-season management decisions were made based on these images, quantification of the damage using the DMSI allows for better decision making to rectify the issues... Crop Updates is a partnership between the Department of Agriculture and Food, Western Australia and the Grains Research & Development Corporation 109.. Depending how the black and white image is generated the black area can vary in size; a minimum and maximum area was calculated and presented in Table 2...

Improving water use efficiency using cover crops of millet... Soil water was measured at cover-crop planting, time of spray-out (2004 replicated sites and all 2005 sites) and at all sites at winter crop planting... In the analysis an average world oil price of US$68.40 a barrel (West Texas Intermediate) and an exchange rate of US74 cents is assumed...

You typically find that the depth to the salt bulge decreases to the west... We have concluded that chickpeas were not as effective as wheat in adjusting yield components under prolonged water stress... The grain yield in the SF early burn and cultivated treatment (2.5 t/ha) was comparable to the other SF treatments in the dry 2002 season despite having the lowest incidence of crown rot infection...

Overall, our conclusion is that while many current uses of yield maps will tolerate low to moderate GPS error, the inability to procure accurate GPS signals will hinder the development of more sophisticated applications of the information for the interpretation of crop behaviour and machine guidance... SSC's limit crop production by limiting crop rooting depth limiting effective plant available water content (PAWC), as well as having direct toxic and nutrient imbalance effects 3... The proportion of the total seasonal water use which is used by a crop after flowering goes a long way to determining the yield and quality of the grain produced...

Under a cloudless March sky, Colin Hutchinson with shovel in hand, was making the year"s big decision - when to sow the first crop... Photo: Too early for rain, but there"s enough moisture in Colin Hutchinson"s soil to start sowing early... "I actually need more silos to hold a greater range of seed, so I can take advantage of early rain with faba beans or if it is a later season I can sow chick peas, or later still I can opt for grain sorghum, sunflowers or maize as a summer crop...

" Agribusiness Crop Updates 2006 Analysis of a wheat-pasture rotation in the 330 annual rainfall zone using the STEP model Andrew Blake and Caroline Peek, Department of Agriculture, Geraldton mm.. KEYMESSAGES Self regenerating biserrula pastures grown in rotation with wheat were more profitable than volunteer pastures based on the assumption that the legume phase can lift wheat yields and improve grain quality... It was assumed that wheat grown in the first or second year after legume pasture would be higher in protein and attract the $10/tonne premium paid in the AH segregation...

The results of experiments conducted in our PA research program suggest that variations in the soil often explain much of the variation in crop performance... Using Figure 4a as an example, spatial interpolation is used to estimate the yield that would have been achieved from treatment 2 in the strips that actually contained treatment 1, and vice_versa... Interpolation: A term describing a number of mathematical procedures which are used to create continuous map surfaces from values measured at points...
