lower plant population

Catalogue: GRDC Updates
There are a range of factors that determine the ability of a seedling to emerge from depth including seed size, seed treatments, coleoptile length, soil conditions and temperature... Figure 3 Effect of sowing depth and seed treatment (dark bar treated with triadimenol on grain yield.. There are a number of studies currently examining the responses of cereal and broadleaf crops to row spacing, and also the interaction with plant population...

Little work has focused on the effect of varying plant population and the carryover effect on soil water available for the critical crop development stages of flowering and grain fill which dictates the extent of yield loss to crown rot... In 2009, five replicated trials were conducted across northern NSW, using the four main durum varieties in the region to assess if the impact of crown rot could be minimised by varying plant populations and variety selection... Plant, tiller and head number per m2 were measured in each plot...

Chances of optimal yields are improved by establishing at least 700,000 plants/ ha (70 plants/m2) even in seasons of low rainfall... Plant populations below 600,000 plants/ha may result in a reduction in yield and increased weed competition... Common features of deep furrow techniques include narrow tines with high breakout pressures, narrow points to minimise soil disturbance and moisture loss and high pressure narrow press wheels (slot into the seed trench and help stabilise it) which reduce the seed-surface distance and help seed/soil contact...
