A search for an environmentally safe and economically viable strategy for control of plant diseases has led to an increased use of plant based products in agriculture. To control the plant diseases, use of fungicides can impact the environment and human health. One method to eliminate these drawbacks is promoting induced protection. This study investigated the use of plants extracts and antagonistic fungi as a biological control of Drechslera graminea or as an inducer of protection in barley plant against the pathogen and also evaluated the possible mechanisms.

The experiment was conducted in plot No. 126 of E block, Main Agricultural Research Station (MARS), University of Agricultural Sciences, Dharwad during kharif, 2011. The geographical co-ordinates of the experimental site are 15026' N latitude and 75007'E longitude and an altitude of 678 m above mean sea level (MSL).The uptake of nutrients by maize increased significantly with incorporation of organic manures with RDF and the highest uptake was recorded in the treatment with PM.

The use of suitable mesh size in the gill net fishery is important as it creates a possibility of protecting the fish, which has not reached the minimum legal or commercial length. For this reason, study on the gill net selectivity of mesh size of Hampala barb catch in Lake Kerinci was carried out from April to October 2013. The length data of fish samples were obtained from fishermen using various mesh sizes gill nets of 1.0 to 4.5 inches.

With the aim to evaluate the efficacy of shadbindu taila Nasya and topical Azelastine hydrochloride nasal spray in the management of Allergic Rhinitis, a Single blind randomized clinical study was done. For the clinical study of Allergic Rhinitis 60 subjects was selected and studied. Subject’s fulfilling the criteria of diagnosis was studied irrespective of their religion, caste, sex and socio-economic status from shalakya-tantra (ENT) department of the institute after thorough scrutiny and proper consent in his/her language.

The success of Indian dairy industry is much dependent on productivity and efficient reproduction performance of Murrah buffaloes. .It is a established fact that first lactation yield is a good indicator of lifetime performance but still there is further need to study the relationship between first, later lactations and lifetime performance traits for overall better evaluation of genetic worth of the female individual’s own performance and for ranking of sires. The literature pertinent to genetic and phenotypic parameters of early performance traits viz.

The study was designed access the neonatal survival rate in puppies delivered through Cesarean Section (CS) under diazepam- propofol-isoflurane anesthesia. A total of 15 newborn puppies delivered through 8 CS were grouped into two groups. Puppies delivered through CS within four-and-half hour after the onset of second stage of labour (7 puppies) and puppies delivered through CS after four-and-half hour after the onset of second stage of labour  (8 puppies) were grouped as Group I and II respectively. New-born puppy survivability was predicted by modified Apgar Scoring system.

In the present study, the yeast Pichia fermentans was isolated from fruit waste and identified and utilized for the biosynthesis of silver (Ag NPs) and Zinc oxide (ZnO NPs) nanoparticles. The synthesized nanoparticles were characterized by X-Ray Diffraction, Transmission Electron Microscopy, Energy Dispersive Spectroscopy and Fourier Transform Infrared Spectroscopy. The characterization study revealed the maximum size of Ag NPs was 98.6 nm and ZnO NPs was 140 nm. The nanoparticles were evaluated for their anticancer activity against Acute Myeloid Leukemia cells (THP1) cells.

Nutritive value and fermentation characteristics of Chloris gayana as sole crop, Clitoria ternatea as sole crop and a mixture of both Chloris gayana and Clitoria ternatea with the effect of stage of growth and phosphorous fertilization was determined using two different techniques: (i) the in vitro gas production and (ii) the in situ nylon bag degradability technique. Samples of 45 and 60 days from sowing were used. The phosphorous fertilization was applied at a rate of 0, 50, 75 and 100 kg P2O5 / ha. Samples were incubated in situ and in vitro for 4, 8, 16, 24, 48, 72 and 96 h.

A total of 50 gastrointestinal tract of domestic pigs were collected in and around Cheyyar taluk, Thiruvannamalai District. The work carried was out for six months from February 2016 to July 2016.Parasitological examination of intestinal tract revealed the presence of helminth parasites and protozoans. Out 50 domestic pigs, 48 (96%) pigs were infected with trematode, cestode, nematode and protozoans. Out 48 domestic pigs 20 were young pigs (below 1 year) and 28 were adult pigs (above 1 year old).Out 48 infected pigs 13 types of parasites were identified using standard procedure.

To understand the effect of sublethal concentration of untreated sugarcane mill effluent water on vital organs of fresh water fish Tilapia mossambica was selected. The biochemical studies on Brain, Muscle and Liver have been carried out. The histological studies on Brain, Gill, Liver, kidney, Testis and ovaries have also been carried out along with control group of fishes.LC50 value was found out before the experiment by the methods of Saptami Moitra and verma (1997). The LC50 was arrived for sugarcane effluent water at a rate of 7ml/lit/per day (i.e.) considered as 1/3 of LC50 value.
