Availability of disease free quality planting material is a major limiting factor in black pepper
cultivation. In order to meet the increasing demand and also to create awareness on good
agricultural practices for healthy disease free planting material production to farmers, a nursery
experiment was started with improved varieties of black pepper by adopting a non-chemical bio-
intensive management strategy. Here solarization of potting mixture was the main concern
followed my amending the solarized potting mixture with potential bioagents. The experiment
was designed in a two factor CRD with four improved varieties and five treatments. Each
treatment contains a combination of two bioagents with antifungal and nematicidal properties
respectively. The common recommended fungicide Metalaxyl-Mancozeb (0.125%) and nematicide
carbsosulfan (0.1%) was used as control. The treatments were incorporated individually into
solarized potting mixture and planted with improved varieties used viz., IISR Girimunda, IISR
Malabar Excel, IISR Shakti and IISR Thevam, The plants in each treatment were kept for
multiplication by serpentine method with proper irrigation and phytosanitation. The results of
plant growth and establishment in different treatments, showed that fortification of solarized
potting mixture with Trichoderma harzianum + Pochonia chlamydosporia combination or combination
of Streptomyces strains (Act 2+9) are significantly superior (35.46% and 21% respectively) for the
production of healthy rooted planting material. IISR Malabar Excel and IISR Thevam produced
the maximum number of plants from a single node cutting in treatment with T. harzianum + P.
chlamydosporia (T1) (59 nos. and 51 nos. respectively) followed by IISR Malabar Excel with Act
2+9 and Act 5+9 (45 nos. each). So an average of 6-7 plants/month/cutting was produced in the
potential treatment while it was only 3-4 plants in control. The advantage of the method is that,
after solarization and fortification with respective bioagents, there is no need for further application
of any fungicides, insecticides or any other nutrient spray as usually done. Thus the method of
soil solarization followed by fortification of either with T. harzianum+ P. chlamydosporia or
combination of Streptomyces strains viz., Ketasatospora setae (Act 2) and S. tauricus (Act9) is found
suitable for the production of healthy quality planting material of high yielding varieties to meet
the increasing demand of planting material with a C:B ratio of 1:2.
