PERFORMANCE OF RICE HYBRIDS AND THEIR PARENTS FOR SALINITY TOLERANT TRAITS IN DIFFERENT SEASONS UNDER SALINE CONDITIONS
Abstract
Ten parents and their 45 F1 hybrids were studied in 4 environments viz., Normal Kharif, Late Kharif in 2011, Normal rabi 2011-12 and Late rabi, 2012 with the objective of identifying stable parents and hybrids in addition to specific parents and hybrids for specific season. The analysis of variance (ANOVA) reveals significant mean squares for genotypes, parents, hybrids and parents x hybrids were noticed for majority of the characters studied in most of the seasons, indicating the existence of variability among the genotypes, parents and hybrids for the various traits studied in the present investigation. The results on mean performance for parents and hybrids for salinity tolerant traits and grain yield for different seasons indicated that higher grain yield per plant was recorded during normal rabi, while shoot length, shoot dry weight, shoot potassium content, root length and root dry weight were higher during normal kharif. While late rabi resulted in higher shoot sodium content.

PERFORMANCE OF IRRI RICE CULTURES UNDER COASTAL SALINE SOILS OF ANDHRA PRADESH
Abstract
The trial conducted at Machilipatnam representing coastal saline eco system with pH - 7.35, EC (dS m-1) - 14.21 and ESP % - 17.57 with 30 rice cultures exclusively bred for salinity at IRRI, Philippines indicated the significant influence of soil salinity, however, only one test culture Pokkali registered significantly higher yield followed by FL 449(IR 66946-3R-149-1-1) with 4.21 t/ha, while the cultures IR 11 T 242 (3.56 t/ha) and IR 11 T 265 (3.28 t/ha) recorded yield at par with the check MTU 1001. The yield superiority of the culture Pokkali is due to the significance of spikelet fertility percent, effective tillers-1, panicle length, and test weight while, FL 449 expressed the yield advantage by way of spikelet fertility percent and panicle length concluding that the test cultures Pokkali and FL 449 can tolerate moderate to high soil salinity(14.21 dSm) and give reasonably good yield.

Biogenic synthesis of zinc nanoparticles from Thevetia peruviana and influence on soil exo-enzyme activity and growth of peanut plants.
Abstract
Zinc nanoparticles were synthesized using Thevetia peruviana leaves extract and characterized using different spectroscopic (Ultraviolet-Visible and Fourier Transform Infrared Spectroscopy) and microscopic (Particle size analyzer, X- ray diffraction, Scanning and Transmission electron microscopy) techniques. Absorption spectrum of zinc nanoparticles showed broad absorption peaks at 327 nm and 254 nm. Average particle size and zeta potential were recorded as 53 nm and 82 mV respectively. Microscopy techniques revealed triangular shaped and poly-dispersed zinc nanoparticles. The synthesized zinc nanoparticles were applied to the pot-culture of peanut and studied soil micro-biota and soil exo-enzyme activities and estimated the physiological traits of peanut plants in 2 regular time intervals of 30 days and 60 days of sowing period. Zinc nanoparticles applied to the peanut pot-culture exhibited good soil microbial and enzyme activities by showing significant variations compared to the control and enhanced the physiological growth parameters of peanut plants.

Seasonal prevalence of gastrointestinal parasites in small ruminants of Cuddalore district of Tamil Nadu.
Abstract
The study was carried out from October 2013 to September 2014 in both organised and small sheep and goat farms of all the six taluks of Cuddalore district of Tamil Nadu, India. The objective of the present study is to determine the seasonal prevalence of gastrointestinal parasites in small ruminants. A total of 2160 faecal samples (90 from goat and 90 from sheep per month) were collected and subjected for analysis. Among the analysed samples 51.66% of sheep and 48.88% of goats were positive for endoparasites. The prevalence of gastrointestinal parasites was higher in sheep than in goats. The nematodes found in small ruminants were Haemonchus spp., Trichostrongylus spp., Oesophagostomum spp. and Bunostomum spp., and Haemonchus sp was found to be predominant in both sheep and goat. The results of season wise analysis indicates that the overall infection percentage was higher in rainy season, northeast monsoon (77.03% and 74.07%) followed by winter (58.88% and 55.55%) and in south east monsoon (48.61% and 27.77%) than in summer (25.55% and 22.96%) in sheep and goats respectively.

LIGHT INTENSITY- NUTRIENT INTERACTION ON THE PRODUCTIVITY, QUALITY AND NET RETURNS OF GUINEA GRASS(Panicum maximum J.)
Abstract
A study was conducted to assess the nutrient requirement of guinea grass (Panicum maximum J.) under open and shaded condition during 2003 to 2005 at
College of Agriculture, Vellayani, Kerala under AICRP on Forage Crops. The experiment was laid out in split plot design with two main treatments of open and coconut tree shade and sub plot treatments of five nutrient levels viz. recommended dose of fertilizers (200: 50: 50 kg NPK/ha) 25, 50, 75 and 100 percent above the recommended dose. The results indicated that the yield of guinea grass is 7 to 25 percent higher in open compared to coconut tree shade while the crude protein content was always higher under shade. The treatment receiving the highest level of nutrients, viz 100 percent above the recommended dose recorded significantly higher green fodder yield, dry fodder yield, crude protein content and crude protein yield throughout the study. Under both light intensities, the highest level of nutrients contributed the highest yield and net returns. Hence it can be concluded that for obtaining high yield and net returns application of NPK fertilizers @ 100 percent above the recommended dose (400:100:100 kg/ha) is required in open conditions as well as under coconut tree shade.

FORECASTING OF AREA, PRODUCTION AND PRODUCITIVITY OF RAGI IN ANDHRA PRADESH USING ARIMA MODELS
Abstract
This paper attempted to identify the trends of area, production and productivity of Ragi (Figer millet) in Andhra Pradesh through fitting different Time series models like ARIMA, Exponential Smoothing techniques. Influence of weather parameters on area, production and productivity of Ragi crop by using Karl Pearson’s correlation and Multiple Linear Regression Analysis was also studied. From the best fitted model forecasting of area, production and productivity was also done. ARIMA (1, 1, 1) model was identified as the best model for area, production and Linear trend was identified as the best model for productivity of the observed data . Accordingly, forecasting was done for the Ragi area, production and productivity up to 2020 AD. It was observed that there was an increasing trend in the productivity, but both area and production was in the decreasing trend during the study period.
It was observed that among all the weather parameters Morning Relative Humidity (RH1) was negatively significant on area and production but it was positively significant on production. In the year 2020 the Ragi cultivated area will be 9100 hectares with a production of 16200 tonnes with an average productivity of 1303 kg ha-1.
Key words: ARIMA (Auto Regressive Integrated Moving Average), Exponential Smoothing, Karl Pearson’s correlation, Multiple Linear regression, Theil’s U-Statistic, R2, Adj R2 and MAPE.

A CASE OF TRYPANOSOMOSIS IN A CAPTIVE ASIATIC WILD DOG (Cuon alpinus)
Abstract
Trypanosoma is an extra erythrocytic hemoprotozoan parasite, transmitted by biting flies and infected meat, causing fever, corneal opacity, anaemia. A male captive wild dog of Arignar Anna Zoological Park, Vandalur aged 3 years had a complaint of anorexia, lethargy, edema of forehead, staggering gait and reduced activity levels in its enclosure. Wet film revealed the presence of numerous motile Trypanosoma sp. Haematological parameters showed anaemia and mild neutrophila. Serum biochemistry was found to be altered. The treatment done was administration of Triquin to the ailing animal. The wild dog was housed in the in-patient ward for continuous monitoring. No Trypanosomes could be detected in the wet film and stained smears taken subsequently. After a week, the wild dog was shifted to its enclosure and is doing well.

CHANGES IN THE FECAL CONCENTRATIONS OF CORTISOL METABOLITES IN RESPONSE TO STRESS IN GAURS (Bos gaurus) IN THREE WILDLFE REGIONS WITH RESPECT TO CLIMATIC CHANGE AND CONFLICT OCCURRENCE-A non invasive study
Abstract
The study was carried out to assess the faecal cortisol concentration in gaur entering the agricultural fields around the forest and in domestic bovines comprising of non descriptive cattle and cross bred cattle, in order to arrive at the baseline values pointing to stress factors. The adjoining areas of Bandipur wildlife region, Sathyamangalam wildlife region and Anamalai wildlife region of Tamil Nadu, India were included in this study programme. The documentation of the quantifiable meteorological factors in the identified conflict areas was done.
The mean faecal cortisol concentration in the case of gaur that entered in the agricultural fields adjoining the Bandipur wildlife region, Sathyamangalam and Anamalai region were found using ELISA (Enzyme Linked Immuno Sorbent Assay). The mean faecal cortisol concentration of non descriptive cattle as well as cross bred cattle was also documented to be used as primary and secondary control values. The occurrences of conflict were also classified as low, medium and high based on the intensity. The climatic inclusions on the stress and conflict levels were studied.
Suitable management related measures were recommended pertaining to the findings observed in this study like increased mean faecal cortisol concentration in gaur, comparative wild gaur- human conflicts pertaining to the variations in the meteorological factors of the areas were studied. The findings demonstrated that fecal glucocorticoid assays provide an index of physiological stress in gaur and may prove useful in addressing conservation and conflict issues

Antifungal Activity of Selected Indian Medicinal Plants
Abstract
The antifungal activity of aqueous and methanolic extracts of ten different Indian medicinal plants were assessed using agar well diffusion test against four different fungi viz, Candida albicans, Aspergillus fumigatus, Aspergillus parasiticus and Cryptococcus sp.The assessment of the minimum inhibitory concentrations of the active extracts were carried out using serial dilution plate technique. A. fumigatus was found to be sensitive to eight out of the ten alcoholic extracts tested where as Cryptococus alone was found sensitive to the aqueous extracts. The alcoholic extract of the seed coat of Tamarindus indica and leaf of Allophyllus cobbe inhibited the growth of C. albicans and A. fumigatus at 12.5 mg/ml where as leaf extracts of Azadirachta indica, Annona squamosa, Mallotus phillipensis and Chromoleana odorata at the same dose rate inhibited the growth of A. fumigatus alone. From the study it could be concluded that eight out of the ten alcoholic extracts tested form promising leads for synthesis of novel antifungal agents.

Effect of pretreatments and curing methods on the flavor profile of essential oil of processed small cardamom (Elettaria cardamomum (L.) Maton)
Abstract
Flavour profile of essential oil in small cardamom (Elettaria cardamomum (L.) Maton) capsules pre treated with one per cent concentration of sodium carbonate, potassium carbonate, magnesium sulphate, sodium hydroxide, sodium bicarbonate, copper acetate, 0.1 percent of ascorbic acid, citric acid, polyethylene glycol and 500 ppm of naphthalene acetic acid and cured under conventional and modern curing methods were analysed using Gas Chromatography Mass Spectrometry technique. Ninety different chemical compounds had been identified in the essential oil of which, the nine main constituents like 1, 8-cineole, α- terpinyl acetate, limonene, linalool, sabinene, trans nerolidol, α-terpineol, linalyl acetate, myrcene were statistically analyzed to find the influence of pre treatments , and curing methods. The higher percentage of the essential oil as well as α- terpinyl acetate, 1, 8-cineole, linalool, α-terpineol and linalyl acetate were noted in the essential oil obtained from small cardamom capsules pre treated with 1 per cent sodium hydroxide and 1per cent sodium carbonate followed by conventional curing. Pretreatment of small cardamom capsules with either 1 percent sodium hydroxide or with 1per cent sodium carbonate for two minutes followed by conventional curing can thus be a better treatment for retaining good flavor profile of essential oil.

ANTIBACTERIAL EFFECT OF GARLIC AND GINGER EXTRACTS ON (Escherichia coli) and (Listeria monocytogenes)
Abstract
Investigations were carried out to study the inhibitory effect of ginger (Zingiber officinale) and garlic (Allium sativum)
extracts at 0.5, 1.0, 2.0, 7.0 and 10.0 per cent level in vitro on Escherichia coli and Listeria monocytogenes by
spectrophotometer method. Both the spices exhibited bacteriostatic effect against both the test organisms. The
inhibitory effect increased with the increase in the concentration of extracts. The garlic extract was more effective
against E. coli than L. monocytogenes. Ginger extract was effective in restricting the growth of E. coli at 0.5, 1.0 and
2.0 per cent level. The minimum inhibitory effect of ginger extract was found to be 8.7 and 8.5 for E. coli and L.
monocytogenes respectively, whereas in case of garlic extract it was 9.1 and 8.0, respectively. It was concluded that both
the spices possess a good potential to act as natural preservative.
