Abstract: A study was carried out to formulate a low cost modified medium as an alternative to the standard Zarrouk medium, to study the growth of Spirulina. The low cost modified medium using the organic substrate neemcake (@ 15g/l) along with baking soda ( @ 16.8 g/l) & sea salt (@ 1g/l) which involved alteration sin N, P and K, Carbon and Sodium Chloride showed moderately significant growth of Spirulina. The growth response of the Spirulina in terms of growth OD, chlorophyll and protein contents were alos significant.

Keywords: Antibacterial activity, Amphimedon viridis, Negombata magnifica
Abstract: Living benthic marine organisms are able to combat microbial attack by chemical defense. Invitro screening of aqueous and ethanol extracts of Amphimedon viridis and Negombata magnifica have the specific activity in inhibiting the growth of six virulent strains of fish pathogenic bacteria (Edwardsiella tarda, Vibrio alginolyticus, Pseudomonas fluorescens, P. aeruginosa, Aeromonas hydrophila & A.salmonicida) was made. The ethanolic extract showed considerably more activity than the aqueous extract. Maximum antibacterial activity was shown against E. tarda followed by A. hydrophila and P.aeruginosa. The aqueous extract appears to have less antibacterial activity than the ethanolic extract. This is interesting in that the traditional method of treating a bacterial infection was by administering a decoction of the sponges, whereas according to out results an organic solvent is better; hence this may be more beneficial. Amongst the 6 bacterial strains investigated E. tarda and A.hydrophilia the most resistant.

Abstract: A study was carried out to assess the viability of hardened and pelleted seeds of pearl millet (CoHCu 8). The seeds were given different hardening treatment using chemicals, growth regulators and botanicals and pelleted Diammonium Phosphate (DAP) and gypsum powder. The treated seeds were packed in cloth bag and 700 gauge polythene bag and stored under ambient conditions. The results indicated that the hardened seeds of pearl millet could be stored for 60 days in cloth bag and 75 days in 700 gauge polythene bag and registered germination percentage of 80, 81 and vigour index of 389 and 392, respectively whereas hardened cum pelleted seed stored in cloth bag could maintain its viability (80%) with vigour index of 360 upto 45 days. The seeds stored in 700 gauge polythene bag and given with hardening cum pelleting treatment recorded germination of 76% and vigour index of 351 upto 60 days.

Abstract: As the crop yield gets differ with different dates of sowing, experiment was conducted with sugar beet to identify the optimum sowing time with three cultivars. The outcome of the study revealed that the sowing time of sugar beet during June first fortnight, September second fortnight and October first fortnight favourably increased the growth of Indus variety by improved growth parameters (plant height, LAI and DMP), yield attributes (root girth and root weight plant-1) and root yield ha-1. Nevertheless, the sugar yield ha-1 was higher with Shubhra variety sown during first fortnight of October (13.8 t ha-1). Sowing the Shubhra variety during October first fortnight can be considered as the best time for higher production of beet sugar in Western zone of Tamil Nadu.

Abstract: Experimental trails were conducted at Kundrakudi to asses the effect of spacing, nutrients and their interactions on yield contributing parameters in onion. The experiments were laid out in split plot design with 10 treatments, replicated thrice. Accordingly, three spacing namely 45 x 5 cm, 45 x 10cm and 45 x 15 cm were adopted and are assumed as main plot (M) treatments. The sub plot treatments (S) consisted of 10 combinations involving three levels of Nitrogen and Phosphorus (20, 40 & 60 kg ha-1), constant level of K (30 kg ha-1) along with FYM @ 25 t ha-1, Azopirillum @ 2kgha-1and phosphobacteria @ 2 kg ha-1. The trials concluded that interaction effects of spacing and nutrients had no significant influence on earliness in flowering. Ther interaction effect of closest spacing (45 x 5 cm) with the application of 60:60:30 kg NPK ha-1, FYM @ 25 t ha-1, Azospirillum @ 2 kg ha-1 and phosphobacteria @ 2 kg ha-1 had registered higher bulb length (5.7 cm ) and shape index (1.1%).

Keywords: Diarrhoeic calves, Rotavirus, Lesions, Histopathology
Abstract: A total of 298 diarrhoea samples were collected from diarrhoeic calves of different farms of West Bengal. The samples collected from diarrhoea cases were subjected to both RNA polyacrylamide gel electrophoresis (PAGE) and sandwich ELISA for detecting rotavirus in the collected stool samples. The infected calves (under 2 weeks of age) showed characteristic symptoms like profuse diarrhoea, dehydration, emaciation and weakness of calves. After thorough post mortem examination of the dead calves, the gross lesions recorded were haemorrhages mainly in different parts of the small intestines like ileum and jejunum. The histopathological examinations revealed atrophy and destruction of the villi, hyperplasia of the linning cells of the intestinal glands, exudation in the submucosal layer and mononuclear cell infiltration suggestive of enteritis. Around 12.4% of the total samples were detected to be positive for bovine rotavirus. The distribution pattern of genes in RNA-PAGE indicated that all the isolates belonged to Group A rotavirus, out of which 25 (80.2%) were found to belong to long electropherotype.

Keywords: Black gram, Red gram, Osmopriming, Seedling characters
Abstract: The investigation under laboratory condition was conducted on pulse cultivars namely, black gram (cv.APK 1) and redgram (cv.APK 1) by using osmoticants like PEG-6000 (-4.5 bars), mannitol (4%) along with botanical invigorates like chicory cold extract (1 & 5%) and Prosopis cold extract (1 & 5%). The present investigation offered a scope for evaluating the seeds through different osmopriming treatments in response to seed and seedling physiology. High significance and reliability were observed in germination (%), Co-efficient of Velocity of Germination (CVG), Vigour Index (VI), shoot and root characters. Seeds osmoprimed with mannitol (4%) chicory extract (5%) showed higher significance for the above parameters. This was followed by PEG 6000 (-4.5 bars). Chicory (5%) showed significant improvement in the chosen seed and seedling characters under water deficit condition. Seed of non primed control seeds leached higher content of total sugar, total amino acids and potassium with higher EC and less pH as compared to osmoprimed seeds.

Abstract: The antimutagenic effect of protein fraction in the presence and absence of metabolic activation system using Salmonella typhimurium strains TA 98, TA 100 and TA 102 were determined by the assay of Ames Salmonella Microsome. Spontaneous reversion of the tester strains to histidine independence is measured routinely in mutagenicity experiments and is expressed as the number of spontaneous revertants per plate in the presence and absence of S9 mixture. The number of revertants in protein fraction treated cultures were found to be identical with the number of spontaneous revertants (SR) indicating their nonmutagenicity to Salmonella typhimurium TA 98, TA 100 and TA 102. The number of revertants showed by the standard mutagen was found to be 516, 554 and 579 for the strain TA 102, TA 100 and TA 102, whereas the co administration of the protein fraction with the standard mutagen significantly decreased the number of revertant frequency (359, 382 & 516), which indicated their antimutagenic effect of the medicinal plant Ocimum sanctum.

Abstract: Studies were conducted under field conditions in rainfed situation at Regional Agricultural Research Station, Lam, Guntur during 2002-03 for evaluating RCH 2 Bt, RCH 20 Bt, and RCH 144 Bt cotton hybrid under unprotected conditions and their corresponding non Bt cotton hybrids under need based protection to bollworms to asses the impact of Bt cotton technology in reducing the damage to cotton crop from bollworms. The incidence of Helicoverpa armigera was low (0 to 3.3% square damage) throughout the peak reproductive phase of the crop in all the Bt cotton hybrids and has not crossed economic threshold level (ETL) (5% square damage) and did not warrant any insecticide application, whereas in non Bt hybrids of RCH 2, RCH 20 and RCH 144 even under need based plant protection damage level is high ( 0.5 to 12.1% square damage) and crossed ETL several times during the crop period. The pink bollworm damage in non Bt hybrids under protected conditions was also high (20 to 26% boll damage) compared to the corresponding Bt versions (3 to 12% boll damage) under unprotected conditions.
