Keywords: Vermicompost, Cereal straw, C:N ratio
Abstract: All the cereal straws used paddy, maize, pearl millet and cholam (sorghum) straw in the vermiculture study, had higher C:N ratio of 88.1, 86.5, 70.3 and 88.0 respectively. More than 90 days are required for the complete compost maturity of cereal straw by vermicomposting process. In paddy straw vermicompost, even after 90 days of composting, the C:N ratio was 22.4, which denotes the immaturity of compost and still more time was required for complete maturity, whereas all other compost recorded C:N ratio of less than 20. In the vermiculture experiment, among the cereal straw, the pearl millet straw and mixed cereal straw recorded 45% more number of earthworms than the paddy straw alone.

Abstract: The cestode parasite, Lytocestus indicus infecting the freshwater teleost, Channa punctatus has been studied for 2 consective years (2005-06) to analyse the incidence of parasitic infection, intensity of infection, index of infection and their seasonal variation. The data obtained during two consecutive years revealed that the parasitic infection has reached it peak during spring. The parasitic infection occurs between autumn and spring. The parasites attain maturity during April to July. It is recorded that the parasitic infection adversely affected the growth of fish and thus most of the infected fish have shown stunted growth.

Abstract: Toxic effect of organophosphate pesticide Phosphamidon on liver of the skipper frog Rana cyanophlyctis has been studied at the concentration between 0.19 and 0.3 ppm and mortality was observed. Mortality was directly proportional with increasing concentrations LC50 values of phosphamidon were 0.274, 0.272, 0.271, 0.269, 0.268 and 0.268 ppm for 12, 24, 48, 72, 96 and 120 h respectively. Histopathologic lesions in the liver was assessed in sub lethal and lethal (0.20-0.33 ppm) concentration of treated animals. Disappearance of cell boundaries of hepatocytes were seen onset of necrosis. There seems to be pycnosis in the hepatocytes.

Abstract: Application of Farm Yard Manure increased the major nutrient uptake rice, millet and groundnut. The poultry manure increased nitrate nitrogen of the leaf tissue at harvest in Douglas strawberry. Application of coir pit based poultry manure increased nutrient uptake in sorghum, cabbage, Bermuda grass and tomato. Application of pig slurry increased the K uptake in wheat, P and K uptake in rye grass and rice. Similarly, total N, P and K uptake increased with increasing dose of pressmud application up to 10 t ha-1 in rice. Increased uptake was also recorded in maize and wheat due ot application of pressmud. Brinjal, chillies, wheat, Douglas strawberry, sorghum crop Bermuda grass, rye grass and maize are positive in nutrient uptake compared to control. Influence of organic N sources on nutrient uptake have been thoroughly envisaged.

Keywords: Chemistry, Fertility, Zinc, Paddy soils
Abstract: Soil survey and crop cutting experiments were carried out for a cluster of villages of Gangavati taluk to study the chemistry and fertility of zinc in paddy soils. Stubbles + ZnSO4 / Zn EDTA, Stubbles + FYM, Stubbles + ZnSO4 / Zn EDTA + FYM and Stubbles were the four different situations in the farmer fields identified for the study. Soils of surveyed area were neutral to alkaline in reaction (7.4 to 8.6), low in salt content (0.18 to 0.21 dsm-1), low to high in organic matter content (2.4 to 8.5 gkg-1) and high in CaCO3 content (4.6 to 12.1%). Residual Zinc fraction was dominant Zn fraction among different Zn fractions, while the values of water soluble + exchangeable Zn were the least (0.18 to 0.13 mg kg-1) which were below the critical limit. Application of stubbles + ZnSO4 / Zn EDTA + FYM resulted in higher grain and straw yield of paddy (61.1 & 81.0 q ha-1 , respectively).

Abstract: A field experiment was conducted to study the influence of different organic wastes (Farm yard manure, press mud, poultry manure, fish meal & pig manure) as nitrogen sources on soil reaction, salinity, micronutrient status of soil and yield of tomato under organic farming. Urea was taken for tomato were worked out and applied. No inorganic fertilizer was added in the case of organic treatment. Application of organic nitrogen sources improved the bulk density (1.44 - 1.35 g/cc), water holdign capacity (40-55%) while the application of press mud decreased the soil pH (7.10-6.80). Application of poultry manure enriched the soil with micro-nutrients viz., Fe (5.3-20.0 ppm), Mn (2.1-15.2 ppm), Zn (1.8-9.5 ppm) and Cu (1.6-7.3 ppm) with increased yield (474 quintals ha-1).

Abstract: The efficacy of neem (Azadirachta indica), castor (Ricinus communis L.), Karanj (Pongamia pinnata Vent.), mustard (Brassica juncea L.), sunflower (Helianthus annus L.), oilpalm and coconut (Cocos nucifera) oils was tested against the fecundity of Callosobrus chinensis in greengram under laboratory conditions. Among the oils C.chinensis produced the lowest number of eggs when grown on neem oil, castor oil and karanj oil recorded the lowest number of eggs per 50 seeds. The similar trend was recorded at 60, 90 and 120 days after treatment. The effect of different oils indicated that there was no adverse effect on germination of seeds at 60 and 120 days after treatment. The seedling vigour index showed a decreasing trend from 60 days after treatment to 120 days after treatment.

Keywords: Rice cultivation, Yield, Water Management
Abstract: Field experiments were conducted at the Tamil Nadu Agricultural University, Coimbatore, to study the performance of different systems of rice cultivation under varied nitrogen levels. These rice cultivation evaluated in the study were: a) direct seedling of sprouted seeds under puddled condition, direct seeding of b) sprouted and c) dry seeds under unpuddled condition and d) transplanting of rice seedlings under unpuddled condition. In the puddled soil condition treatment plots, 5 cm depth of water was maintained throughout the crop growing period. In respect of unpuddled condition plots, 5 cm depth of irrigation was given at 80 percent of the available soil moisture condition. The nitrogen levels were : 50, 75, 100, 125 and 150 percent of recommended dose of nitrogen. Direct seeding of sprouted seeds under puddled condition recorded higher grain yield than other systems of cultivation. Among the nitrogen levels the beneficial effect was evident at 150 percent of recommended dose of nitrogen which was comparable with that at 125 and 100 percent of recommended dose of nitrogen. The water savings and water productivity (Kg m-3) was higher in direct seeding of sprouted seeds under unpuddled soil condition. In water scarcity situations, the direct seeding of sprouted seeds under unpuddled soil condition along with 100 percent of recommended dose of N could be a viable alternative in terms of efficient water use and water economy.

Abstract: Freshly harvested onion seeds treated with vermiwash recorded significantly higher germination (80.6%), numerically high growth rate index (19.3), shoot length (8.5 cm) and seedling dry matter accumulation (22.3 mg) while the six month stored onion seeds treated with Panchagavvya recorded numerically high values with regard to above parameters. Hence, it can be noted that freshly harvested seeds of onion should be treated with vermiwash and stored seeds with Panchagavvya to get good seed germination, seedling vigour and high accumulation of dry matter in onion seedlings.

Abstract: Effect of ethanolic extract of leaves of Enicostemma littorale Blume was investigated in the rat to evaluate anti-inflammatory activity. Carrageenan induced rat paw edema model and cotton pellet granuloma methods were employed to test anti-inflammatory activity. The ethanolic extract (150 mg/kg) produced 59.5% of inhibition of carrageenan induced rat paw edema and also found to be effective in cotton pellet granuloma studies. The result indicated that the ethanolic extract produced significant (P<0.001) anti-inflammatory activity when compared to control.
