pepper nursery' was conducted at the College of Horticulture, Vellanikkara during
January to August 1998. Potting mixture was inoculated with Phytophthora capsid
Leonian, emend. Alizadeh and Tsao before solarization. Transparent, 150 guage
polyethylene sheets were used for solarization of the potting mixture.
Maximum soil temperatures recorded at 10 cm depth III solarized
potting mixture was 51.0°C while, it was 42.0°C in non-solarized one.
Soil temperature of solarized potting mixture was more than 45°C for 40
days and above 50°C for four days.
Solarization enhanced the sprouting of pepper cuttings. Solarization was
effective in reducing the pre-sprouting mortality and mortality of rooted cuttings
by the pathogen.F ortyfive days solarized, Trichoderma viride incorporated
Fytolan drenched treatment exerted cent per cent control of the mortality of rooted
cuttings.
Solarization significantly reduced the foliar infection of rooted cuttings.
Forty five days solarized, T viride incorporated treatment was highly effective and
recorded 97.22 per cent control of the disease. Maximum disease incidence
(87.58%) was noticed in the non-solarized control.
Reduction in Phytophthora population ranged from 94.41 to 97.35 per
cent in solarized potting mixture immediately after the removal of polyethylene
sheets.
Maximum population of Trichoderma spp. was observed in solarized
Trichoderma spp. incorporated treatments.
Solarization reduced fungal, bacterial and actinomycetes population of
potting mixture.
Plants grown in solarized potting mixture exhibited better colonization
of Azospirillum. However, root colonization of V AM in pepper cuttings was less in
solarized treatments.
Availability of nitrogen, phosphorus and potassium was increased by
solarization.
Solarization effectively reduced the weed population ill the pepper
nursery.
Solarization resulted in increased growth response of rooted pepper
cuttings. All growth parameters like height of plants, number of leaves, length and
breadth of leaves and development of root system were influenced by solarization.
