Description Field experiments were conducted at Agricultural College Farm,
Shimoga during kharif of 2010 and 2011 to develop organic manurial
practices for the production of dry chilli. A field experiment was laid
out in Randomized Complete Block Design with twenty treatments
and three replications. Initial growth parameters were significantly
higher with the application of RDF but, leaf area dropped from 6.62
dm2 plant-l at 90 DAP to 5.10 dm2 plant-l at 135 DAP due to foliar
diseases (leaf spot and powdery mildew during 2010 and 2011,
respectively). Application of poultry manure as basal dose (3.5 t ha-1)
and top dressing either with poultry manure (3.5 t ha-1) or with
Glyricidia leaves (2.0 t ha-1) registered significantly higher dry chilli
yield (588 kg ha-l) than application of RDF (543 kg ha-l).
One nursery experiment was conducted to study the effect of
organic manures on chilli seedling production. The experiment was
laid out in RCBD consisting of eight treatments and replicated thrice.
The results revealed that green manuring with Glyricidia leaves
(0.2 kg sq. m-1) produced taller (19.8 cm) and higher total dry weight
of seedlings (0.63 g plant-1) and found on a par with the application of
RDF. Incidence of Cercospora leaf spot was comparatively high during
2010 with the application of chemical fertilizers.
An experiment on composting was conducted in shade net
house to optimize initial C:N ratio; was laid out in CRD with nine
treatments and three replications. Optimizing initial C:N ratio of the
substrates to 30:1 by using Glyricidia leaves resulted in significantly
higher reduction in volume (61.13 %) and registered significantly
higher nutrient content at 90 days after composting and found on a
par with composting of Glyricidia leaves alone.
