Spring drilling guide as­sumes es­tab­lish­ment at 80-90pc

Irish Independent - Farming - - Cereals -

IN THE Tea­gasc Spring Ce­real Drilling Guide 2014, the as­sumed es­tab­lish­ment is in the range of 80-90pc.

This takes into ac­count the ex­cel­lent seed this year and as­sumes a re­turn to nor­mal spring con­di­tions, but we al­ways ad­vise peo­ple to ad­just this fig­ure to field con­di­tions and your own TGWs.

The bar­ley fig­ures are based on the tar­get of grow­ing and har­vest­ing 900-1,000head/m2.

Til­ler­ing ca­pac­ity of va­ri­eties, drilling date, fer­til­ity and weather all in­flu­ence this fig­ure but ini­tial seed­ing rate prob­a­bly has the big­gest in­flu­ence.

The stand­ing power of va­ri­eties needs to be given due thought, as lodg­ing risk in­creases as plant num­bers in­crease.

Fi­nally, a lit­tle back­ground in­for­ma­tion on the Depart­ment va­ri­ety tri­als.

All th­ese tri­als are drilled at a seed rate of 320seeds/m2 and are given the in­puts re­quired to achieve high yields.

Lodg­ing scores are from plots given an ex­tra bag of ni­tro­gen and, if pos­si­ble, left stand­ing be­yond the ideal har­vest date so as to test straw to its lim­its.

The fig­ures are ro­bust and re­li­able enough to drill a sim­i­lar seed rate on farm, as in the seed rate guide here.
