Keywords: Physico-chemical characteristics, vermicasts, Earthworms, Fungal flora
Abstract: Characteristics of fungal flora in the casts of the earthworm revealed that the vermicasts of Perionyx ceylanensis showed 14 different fungal species belonging to the genera, Aspergillus, chaetomium, Cladosporium, Cunninghamella, Fusarium, Mucor, Penicillium and Rhizopus. Total nitrogen, phosphorus, potassium, calcium, copper, iron and zinc were high in vermicasts compared to control (worm-unworked substrate), while organic carbon and C/N ratio were lower in vermicasts. The incubation of vermicasts (45 days) showed significant correlation with that of the increase in fungal population (r=0.720; p<0.05), decrease in moisture content (r= -0.984; p<0.001) and the decrease in moisture content had no effect on the total fungal population in the vermicasts of P. ceylanensis.

Keywords: Chrysanthemum flowers, Vase life, Chemical treatment
Abstract: With an objective of improving the post harvest life of cut chrysanthemum flower cvs. White Fizii and Peach Fizii, they were harvested when the flowers just opened and taken to the laboratory within 24 hours after harvest. The flowers were treated with Aluminium sulphate (Al 2(SO4)3) (100, 200 &300 ppm) and Cobalt sulphate (CoSO4) (0.5, 1.0 & 1.5 M). The best concentration obtained from previous trial was treated with sucrose ( 2 & 4%). Finally, the best combination obtained from combining mineral salts and sucrose was incorporated with germicide, 8-Hydroxy Quinoline Sulphate (8-HQS) at 100 and 200ppm. Among the treatments tested, 300 ppm (Al 2(SO4)3)+ 4% sucrose + 100 ppm 8-HQS had recorded maximum vase life of 25.8 days in cv. White Fizii as compared to 14.8 days in control and registered better water balance (+8.0) in comparison to control (-10.0). Whereas, in the case of cv. Peach Fizii, 0.2 M CoSO4 + 4% sucrose not only showed increased vase life of 29.0 days against 19.2 days in control, but also recorded positive water balance (+20.8) versus control (-8.6), against 19.2 days in control , but also recorded positive water balance (+20.8) versus control (-8.6).

Keywords: Chromium, Toxicity, Labeo rohita, Blood glucose, Hepatic glycogen
Abstract: Effect of chromium, heavy metal widely used in tannery industry was investigated on blood glucose and hepatic glycogen in Labeo rohita. L. rohita were exposed to different concentrations of chromium for 96 h and percent mortality noted. LC50 value for 96 h was 5.5 mg/l. One-tenth of LC50 (0.55 mg/l) was selected as sub lethal concentration (SLC) for chronic studies ( 7, 14 & 21 days). When fish was exposed to 10% SLC of chromium for 21 days, the glycogen content in liver (-56.9) was decreased, but blood glucose level ( + 28.6 %) was increased. Analysis of the data suggests that blood glucose and hepatic glycogen profiles can be used as indicators of pollution stress.

Keywords: Available nutrients, Coleus forskohlii, Phosphorus, Nitrogen, Potassium
Abstract: Field investigation conducted during 2004-05 at Arabhavi, revealed that available nitrogen (N) was higher at higher levels of N (100 & 150 kg/ha) application during second season (2005) and in pooled data. However, different levels of phosphorus (P) and potassium (K) and the interaction effects of nutrients did not influence the available N status in the soil during both the seasons and also in pooled data. Graded levels of P and K did not influence the available P2O5 in soil. Available P2O5 was higher in the treatment combination N150P100K100 (34.8 kg/ha), N100P100K150 (35.0 kg/ha) and N50P100K50 (34.9 kg/ha). Different levels of N and P did not influence the available K2 O. But, application of higher levels of K (150 & 100 kg K2 O/ha) recorded higher available K2 O in soil after harvest of the crop (338.5 & 312.1 kg/ha, respectively). Nutrient interactions were found to influence available K2 O only during first season recording significantly higher in N100P50K150 and N100P50K150 (377.3 & 376.3 kg/ha, respectively).

Abstract: Phytochemicals, especially botanical insecticides are currently of interest because of their successful application in plant protection as biocontrol agents. Biological activities of leaf aqueous extract of twenty five selected medicinal plants were evaluated against VI instar larvae of gram pod borer Helicoverpa armigera (Hubner), (Lepidoptera: Noctuidae). Preliminary screening after 24h of exposure to leaf aqueous extracts of the selected plants at a concentration of 1,000 ppm exhibited significnat larval mortality rate. The percentage mortality rate ranged considerably from 10.8 to 86.4. The mortality rate was observed in the decreasing order of Toddalia asiatica (86.2) > Melia azedarach (78.9) >Solanum trilobatum (74.8)> Andrographis paniculata (72.8) > A. lineate (71.5) > S. surattrense (70.3) > Catharanthus roseus (67.8) > Adhatoda zeylanica (67.2) > Acalypha fruticosa (66.3) > Datura metal (62.9) >S. nigrum (61.8) >Ocimum canum (58.2) > O.sanctum (57.9) > Plectranthus coleoides(57.8) >Pergularia daemia (55.2) > Gymnema sylvestre (51.9) > Albiziz amara (51.8) > Cardiospermum helicacabum (49.1) > Ceropegia candelabrum (48.1) >Vitex negundo (45.5) > Abutilon indicum (36.7) > Cassia tora (31.8) > Tribulus terrestris (25.2) > Achyranthus aspera (16.8) > Aerva lanata (10.8) against the larvae of H. armigera. The results imply that leaf aqueous extract of Toddalia asiatica, Melia azedarach, Solanum trilobatum, Andrographis paniculata, Andrographis lineate, Solanum surattrense, Catharanthus roseus, Adhatoda zeylanica, Acalypha fruticosa, Datura metal can potentially be used as eco-friendly pest control agents against the larvae of H. armigera.

Abstract: A field study conducted during 2004-05 at Arabhavi, Karnataka showed that lower population densities of Coleus forskohlii (55, 555 & 66, 666 plants/ha) recorded higher number of tubers/plant (18.3 & 16.5, respectively), tuber length (20.3 & 20.8 cm, respectively), diameter (12.4 & 13.1 mm, respectively) and density of tubers (1.09 & 1.13 g/cc, respectively) and also yield/plant (23.2 & 21.7 g, respectively) on pooled basis at harvest, and also at other growth stages. Increase in plant density decreased all the yield attributes. But, fresh (13.74 t/ha) and dry (1.57 t/ha) tuber yield/hectare was recorded higher at higher population density of 83, 333 plants/ha. Harvesting time of 160 and 180 days after planting (DAP) were found equally superior in terms of yield attributes and tuber yield. Thus, planting C.forskohlii at higher plant density of 83, 333 plants/ha and harvesting at 160 DAP was found optimum for getting higher tuber yield.
