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. |
