Introduction

As growers we spend our days trying to convert light into energy The scientist would say we aren’t doing a brilliant job Theirs loads more potential out there Where are we wasting it/ not utilizing light?

SLIDE 3

Bud Numbers

An average tree with an average number of flower buds could start the season with over 2000 buds We need 150 – 200 Excessive bud numbers ‘could’ be wasting energy and ‘could’ be stopping energy being used in the right place

‘The Row!’

This row would suggest we are!
Envy at Plant and Food Research in NZ
Has been in ASE for a number of years
Yielding in excess of 160 T/Ha without

any bianulism

Methodology

So how could we go about it ? Cropping units / linear Metre of tree (6-7) allowing light distribution through the tree …… dappled light. Removal of over vigorous units/branches – 5 buds per BCA

This alone can make a massive difference

Convert in an ‘on’ year ! Only works in balanced orchards Dial up the crop

Cost?

Rome wasn’t built in a day ! Year one study at La Moriniere, suggested £566/Ha to do ASE 0.22p/tree ! Limited hand thinning needed and cost drops in subsequent years After conversion trees tend to produce lots

f nice ‘bourse shoots’

Hasn’t shown big benefits in year one – buds & Light
