Abstract

Two greenhouse strawberry production studies were performed. In the
first study, strawberry plants were grown in filtered aquaculture
effluent. Freshly dug plants of cultivars Chandler and Sweet Charlie
were transplanted on 1 October 1995 in vertically-stacked square
pots (28 plants/m2) containing coarse perlite. The plants were fertigated
continuously with commercial nutrient solution (pH 6.4 and EC=0.6
mS/cm) or with once-through aquaculture effluent (pH 7.2, EC=1.6
mS/cm, 6 mg/litre total suspended solids). Since nutrient concentrations
in aquaculture effluent were about 15% of the levels measured in
commercial nutrient solution the following nutrients were supplemented
(mg/litre): NO3--N (18), P (0.7), K (5), Ca(55), Mg (20) and S (9)
and all micronutrients. However, the growth and fruit production
(200 g/plant) in plants fertigated with aquaculture effluent was
low due to poor light conditions in the middle and bottom portions
of the tower system and deficient levels of tissue N and P. In the
second study, freshly dug and runner-tip plants of cultivars Camarosa,
Chandler, and Sweet Charlie were grown with a continuously flowing
commercial nutrient solution in nutrient film technique (NFT) troughs
(13 plants/m2) from October 1996 to May 1997. Sweet Charlie produced
fruit the earliest, beginning in early December, and Camarosa produced
the most fruit (445 g/plant). Generally runner-tip plants performed
better than freshly dug plants. These studies indicate that a soilless
strawberry production system for off-season fruiting in the middle
Atlantic coast region is possible.
