Three non-chemical weed control alternatives (chicken manure
(10 t ha-1), olive processing waste (OPW) (30 t
ha-1), and solarisation (6-7 weeks at > 40.9 -
47.1oC at a 15 cm soil) were applied to
greenhouse grown tomatoes alone and in combination and were
compared with a soil fumigant (dazomet) for the ability to
control weeds. Both dazomet (485 kg a.i. ha-1)
and solarisation provided excellent control of common
purslane, slender amaranth and bristly foxtail. Excellent
weed control was also achieved with a half dose of dazomet
(242.5 kg a.i. ha-1) plus 21 days of
solarisation. OPW provided moderate control of these weeds,
but chicken manure did not. OPW and chicken manure applied
with solarisation provided 100% control of common purslane,
slender amaranth and bristly foxtail, but did not
significantly improve control compared to solarisation
alone. OPW plus a short-duration of solarisation may provide
weed control that is comparable to dazomet in greenhouse
grown tomatoes.
Key words:
Chicken manure, olive processing waste, solarisation,
