Abstract: Hepatitis B virus (HBV) infection
affects millions of people worldwide and about a half million people die
every year. It is a serious liver disease, caused by hepatitis B virus. The
disease is transmitted through human body fluids such as blood and serum.The objective of the study is to identify the
optimal age for revaccination.All the subjectswere received vaccination under vaccination
project at childhood age. Serum was separated and the titre
of anti-HBsAg was estimated using quantitative
method of double antibody sandwich-ELISA.There were
100 subject included in the study. Seroprotective
rate decreased significantly with increasing time from last vaccination due
to decrease in anti-HBsAg titre
over time.Hepatitis B vaccination has been accepted
to induce the protective antibody level after the complete dose of
vaccination. Anti-HBsAg concentrations declined
over time among studied subjects successfully immunized with HB vaccine
starting atbirth. The study shows that male were
more prone to hepatitis B infection as compare to femaleThe
correlation analysis revealed a highly significant negative correlation (r =
0.92, t= 9.95, p<0.05) between different age groups and conc. of Anti HBsAg of sera samples of selected individuals. HB
vaccine-boosting could be advised for high risk subjects including adult
health care workers and children at endemic area at twenty years intervals. Key words: Hepatitis, Vaccination, Anti-HBsAg

Abstract: Endosulfan is an important
chlorinated hydrocarbon pesticide used against insect pest for a number of
diverse applications and more specifically used in poultry farming in India
for the control of termites in chicken houses. Twenty White Leghorn birds were
given Endosulfan in drinking water @ 30 ppm/bird/day (no observable effect level dose) for a
period of three months to investigate the physical and productive changes in
the birds after limited oral administration of Endosulfan
insecticide. Production performance, serum calcium and phosphorus levels of
layer birds were estimated at 15 days intervals. There was significant
reduction of 22.81% in average egg production and 8.18% decrease in percent
hatchability on total egg set basis, however, average egg weight was reduced
by 3.08%, fertility was reduced by 4.94% and percent hatchability on fertile
eggs set basis was mildly decreased by 4.03% due to exposure to endosulfan. The calcium and phosphorus levels were
progressively reduced from 15-90 days of treatment. The level of phosphorus
(26.32-35.19%) was more severely affected than that of the calcium levels
(13.92-26.68%) in the endosulfan treated group as
compared to control. Present investigation reveals clear productivity losses
due to presence of this insecticide warranting need of removing the chemical
insecticide from the life cycle of layers. Key words:

tuberose showed highest values of vegetative character plant height, spread,
number of leaves and sprouts/ clump over all the concentration of plant
growth regulators tested. Study also showed that application of GA3
at 300 ppm among all the treatments of GA3, ethrel and MH
exhibited early spike initiation, opening of first floret, maximum
duration of flowering and spike, number of florets/ spike, floret weight/
spike as well as bulb and bulblets yield/ha. There
was significant decrease in yield parameters like bulblets/clump,
yield of bulblets, number of bulb, weight/ clump,
yield of bulb with increase in the application of maleic
hydrazide from 50-150 ppm.
The maximum benefit cost ratio and net return was highest 2.15 and 701336.69 Rs/ha followed by treatments of
GA3 at 200 ppm with bebefit
cost ratio of 1.73 and 556136.69 Rs/ha.

Abstract: An experiment was conducted at Krishi
Vigyan Kendra, Basti (UP)
with two high yielding rice varieties to standardize the System of Rice
Intensification (SRI) method including the age of seedling and variable
spacing. The SRI standardized package was compared with the conventional
production system of rice at farmer’s field. Maximum grain yield (66.80 q/ha)
along with all the contributing traits i.e. plant height (130.0 cm), root
depth (30.0 cm), root spread (20.66 cm), root biomass (16.75 g/m²), number of
tillers (36), spikes (27), spike length (32.66 cm), grains/spike (285), test
weight (37.3 g) and grain yield (66.80 q/ha) were recorded in variety NDR-359
with 10 days of seedling age planted at 25 X 25 cm spacing. Similar trend of
observations were also recorded through this spacing in case of variety
PNR-113, where, plant height (120.33 cm), root depth (27.0 cm), root spread
(16.66 cm), root biomass (16.80 g/m²), number of tillers (33), spikes (26),
spike length (28.60 cm), number of grains/spike (282), test weight (35.25 g)
and grain yield (65.70 q/ha) witnessed. At farmer’s field in demonstration trial
14.44 per cent increase in grain yield through SRI practice was remarkable.
It is an eco-friendly approach because it helps in resource conservation
owing to its need of less exploitation of ground water, no use of any weedicide and minimum use of other hazardous chemicals
(insecticide/ fungicide). Key words: Rice,

various heterotic effects varied from cross to
cross and character to character. However, greater amount of relative heterosis, heterobeltiosis and
standard heterosis were observed for cured leaf
yield per plant and important yield component attributes. The crosses, which
exhibited higher estimates of relative heterosis
for cured leaf yield were ABD 10 x Red Russian (44.96%), ABT 10 x Red Russian
(23.07%) and GT 9 x GT 7(18.91%); whereas, the superior crosses in respect to
heterobeltiosis were ABD 10 x Red Russian (21.92%),

Abstract: The present investigation was undertaken in cold desert of Spiti Valley, Himachal Pradesh to assess morphological, biochemical and leaf proximate composition diversity of Hippophae rhamnoides
populations. Nine major gene pool areas and three growing
conditions within major gene pool areas, selected for the study showed wide
variation among different morphological, biochemical and leaf proximate
compositions traits. On the basis of results, eventually, it may be concluded
that GPA-4 (Schilling) was superior than other major gene pool areas for leaf
proximate compositions with highest crude fibre
(18.22%), crude protein (21.60%) and total ash (11.38%) and GPA-3(Sheigo) for fruits (18.54 g), seed (2.99 g) and
biochemical parameters i.e. juice content (80.05 %), Total sugar content
(5.94%) and ascorbic acid ( 595.13 mg/100 gm) among different major gene pool
areas. And, for fodder purpose, GPA-4 (Schilling) and for fruits quality
parameters, GPA-3(Sheigo) major gene pool area, are
the best for further utilisation. Over all, GC-3
(Crop land) was found superior for all morphological traits among different
growing conditions under different major gene pool areas. Based on the
morphological, biochemical and leaf proximate compositions traits
observations, it was evident that large diversity exists in naturally growing
populations of Hippophae rhamnoides
in the Spiti Valley of Himachal Pradesh, and thus
morphogenetic variation can be exploited for the further selection of

Abstract: The aim of our study was to determine changes in enzyme activity
(Ascorbic acid oxidase and catalase)
and ascorbic acid content after the application of pesticides thiodicarb, spinosad, profenophos and chlorantraniliprole
at recommended dose. The experiments involved two kharif
(2013-14 and 14-15) and two rabi (2013-14
and 14-15 season. The four different varieties of brinjal
( Malapur local-V1,
Kalpataru-V2, Manjula-V3,
Manjari-V4) screened in experiments. The
effect of pesticides belonging to different chemical groups i.e., thiodicarb (carbamate), spinosad (naturalyte bacterial
origin pesticide), profenophos (organophosphates),
and chlorantraniliprole (anthranilic
diamide) varied due its persistence and half life.
Ascorbic acid content in brinjal fresh fruits
differ significantly in pesticide treatments at all the stages. Data recorded
for ascorbic acid content showed maximum in V4P3
(5.12-5.30 mg 100 g-1) in both the seasons. On the contrary,
however, it decreased with 115 to 125 DAT, the maximum AA content declined in non-sprayed
control (3.71-2.22 mg 100 g-1).
Among interactions, AAO activity did not differed significantly at 90
DAT during kharif. The activity of ascorbic
acid oxidase indicated maximum (15.65 unit min-1
g-1)) in non-sprayed control compared to sprayed treatment. The minimum activity recorded in V4P3
(7.30 unit min-1 g-1) might be due to AAO response to
biotic stress. The effects on CAT activity was dependent on pesticide
treatments showing highest value (30.63 units g-1) in variety Manjari treated with profenophos
after 4 days of spraying and their compounds accumulated in the fruits
creating chemical stress in plants. Key word: AAO-Ascorbic

symptoms of haemorrhagic gastro enteritis was made
against CPV infection through Polymerase Chain Reaction (PCR)& KIT test
method based on the basis of breeds, age and sex. The young pups between age
groups 4-12 months were found mostly susceptible to Canine parvo viral haemorrhagic
gastroenteritis as compared to other age groups. Further, the male dogs were
found to be more affected than female dogs and large dog breeds were more
affected than other breeds. The age wise analysis of faecal
sample by KIT Ag test method revealed that the number of positive cases for
CPV infection was 15.5%, 70.685% and 13.79% of animals belonging to age group
1-3, 4-12 and more than 12 months of age, respectively. whereas by PCR method
revealed that the number of positive cases for CPV infection was 18%, 62% and
20% of animals belonging to age group 1-3, 4-12 and more than 12 months of
age, respectively. The sex wise positive cases for CPV by KIT Ag test method
was 67% and 33% for males and females, respectively whereas PCR method
revealed that the positive cases were 68% in case of male and 32% among
female. In the present study, it was found that the PCR method was more
reliable, accurate and cost effective than KIT Ag method of diagnosis. The
KIT Ag method of diagnosis is of more importance in field conditions for

Abstract: Fusarium wilt is one of the
major yield limiting factors in tomato. In vitro and In vivo
efficiency of two species of antagonists (Trichoderma
viride and Trichoderma
sp.) alone and in combination were evaluated against the pathogen (Fusarium sp.). In vitro results
showed that Trichoderma viride and Trichoderma
sp. significantly inhibited the mycelial
growth of the pathogen. The mycelium inhibition of Fusarium
was more effective by Trichoderma viride (52.31 %) compared to Trichoderma
sp. (47.09 %). Both the species of Trichoderma
also inhibited the growth of Fusarium in
tomato planted pots as evident by the decrease in disease severity. The
combination of both species of Trichoderma
was more effective in controlling the disease along with increasing the
tomato yield (34 % increase compared to the control) compared to their
application as alone. Key words: Trichoderma,

Abstract: Gladiolus (Gladiolus hybridus L.)
popularly known as “Queen of bulbous flowers”, member of family Iridaceae, is one of the most important bulbous
ornamentals grown for its majestic spikes which contain attractive, elegant
and delicate florets. The present
investigation was carried out with 20 genotypes of gladiolus (Gladiolus hybridus L.) which were evaluated during 2013-14 in
randomized block design with three replications. The performance of gladiolus
data was highly significant for all the vegetative, flowering and corm
traits. Cultivar Praha (81.28 cm) gave the maximum
plant height followed by Regency (77.33 cm) whereas cultivars ‘Nathan White’
and ‘Arka Kesar’ were
found earliest for spike initiation (56.01 day, 56.39 day respectively) and
first floret showing color (68.77 day, 69.01 day respectively). The longest
spike length and rachis length were found in Praha
and American Beauty. Maximum number of florets per spike was found in
Pacifica (14.87) and Yellow Golden (14.83). The maximum corm diameter (6.97)
was found in Regency followed by Nathan White (6.56) whereas maximum numbers
of cormels per plant were found in Tiger flame
(33). Looking into performance of different cultivars, Praha,
American Beauty, Pacifica, Tigar Flame and
Priscilla can be recommended for cut flower production whereas Regency,
Nathan White and Fidelio could be taken up for quality corm and cormel production and can also be further utilized in
gladiolus improvement programme. Key words: Genotype,
