This season could only be classed as stressful with a cold start, slow plant growth, excessive insect pressure and heat that lasted all summer and into March. The crop in mid January had very few fruit numbers but once insect pressure dropped off did a lot in a short period of time. Although the Sicot 754B3F looked the best in the trial the Sicot 746B3F showed its resilence coming through and winning the trial in a hot season. Good mangement was the key in a year that had everything. Despite the tough year the quality was very good in this trial.

This field was sown into moisture on the 6/10 and emerged pretty well.
The field was prepared early before the wet into fallow from wheat
that allowed us to plant into moisture. Numerous cold shock days through
October and into November meant very slow development and fruit set.
Big heliothis egg lays further reduced fruit set into December meaning very
low retention in early January. We used a pyrethroid spray in early January
which did help increase fruit retention but also flared white fly. The crop
was watered all summer on tight intervals and did not appear to stress at
any stage despite the heat. It was defoliated in late march and looked a really
showy crop at picking. The yield was dissapointing but probably a good result
given the season. I was surprised to see the Sicot746B3F on top and it definitely did’nt
look the best but again it has proved to be a pretty safe variety, with a high out turn
bringing home the goods. 146 mm of rain fell in mid march but did not cause any
classing problems and helped wash off some honey due.
