Abstract: The study was to
determine the utility of sonography in the
diagnosis of bowel obstruction in dogs.One hundred
and fifty clinical cases of dogs of different ages and breeds, presented to ultrasonographic unit of Veterinary college hospital, Hebbal, Bengaluruwere utilized
for the present investigation.The criteria for
simple small bowel obstruction (SBO) includes,the
presence of fluid-filled dilated small bowel (diametere”25 mm) proximal to
collapsed small bowel or ascending colon andthe
presence of peristaltic activity (observed as peristalsis of the intestinal
wall or to-and-fro movements of spot echoes inside the fluid-filled dilated
small bowel) in the entire dilated proximal small bowel. Out of the total
cases examined over a period of one year only five cases were confirmed of
intestinal obstruction. Three dogs had complete blockage in the small
intestine and signs include persistent vomiting, weight loss, and
dehydration. Dogs with complete blockage of small intestine, there were
luminal dilation resulting in jejunal diameter of
>1.5 cm and in dogs with incomplete obstruction ultrasonography
revealed a peach pit in the lumen of a mildly fluid distended bowel segment
and there was a strong acoustic shadow associated with the foreign body. From
our study findings it is concluded thatultrasound
has the potential to diagnose complications of bowel obstruction that are not
easily identified using clinical x-ray criteria, and the examination can be
performed in the emergency at the bedside, thus facilitating patient care. Key words: Sonography, Intestinal

Abstract: A pot culture was conducted to evaluate the sensitivity
of Spinach to nickel at 200µM, 500µM, 1000µM concentration. The response of
spinach towards elevated level of nickel (500µM, 1000µM) shows that its
effect was inhibitory on catalase (CAT), total
protein and sugar content at 45 and 90 days of observation. However damage
was recovered by boron and copper as compared to lone concentration of Ni
(500µM, 1000µM).The estimated activity of peroxidase
(POD) from lower to higher concentration (200µM, 500µM, 1000µM) was increased
in leaves of spinach plant on 45 days (11.64, 14.55, 20.63, 23.41 “O.D./g) and 90 days (12.71, 18.56, 25.51,30.16 “O.D./g) of
analysis. The concentration of total protein in 45 days spinach leaves at
excess Ni levels was decreased from the values of control level (87.17,
83.92, 53.56, 40.80 µg/g). The rate of decrease in protein was also observed
in 90 days of analysis (154.17, 146.26, 103.59, 82.51 µg/g). whereas, protein
was improved in each treatment of Ni (500µM, 1000µM) with B (150µM, 300µM)
and Cu (50µM, 100µM) as compared to lone
application of Ni (500µM and 1000µM). Increase level of Ni progressively
decreased sugar in spinach leaves on 45 days (2.85, 2.49, 1.83, 1.00 µg/mg)
and 90 days (2.61, 2.26, 1.44, 0.760 µg/mg). Eventually, it was improved in
recovery treatment as compare to lone concentration of Ni on both time points
of analysis (45 and 90 days). Key

Abstract: The root
nodulation and yield of chickpea plants grown with different Fe
concentrations and Rhizobium culture was
studied in comparison to the un-inoculation at screen house. Treatments
consisted four levels of iron i.e. 0, 2.5, 5.0 and 7.5 ppm and two levels of microbial inoculation i.e.
un-inoculation and inoculation with Rhizobium.
The treatments replicated four times in completely randomized design
(factorial) in cemented pots. The results indicated that among the iron
levels, 5.0 ppm showed better effect on number of
nodules per plant (14.00, 19.00 and 10.00) at 30, 60 and 90 days after sowing
(DAS), respectively. The grain (20.03 g pot-1), stover (23.97 g pot-1) yield and test weight
of seeds (20.90 g) was also significantly increased with 5.0 ppm ferrous chloride in comparison to 0, 2.5 and 7.5 ppm levels. The seed treatment of chickpea with Rhizobium culture significantly increased the root
nodulation (12.00, 18.50 and 8.75, respectively),
grain (19.78 g pot-1) and stover (23.73
g pot-1) yield and test weight (20.85 g). In future, the
experimental results may prove very useful for increase the nodulation and
yield in chickpea with test weight. Key words: Chickpea, Iron,

variability for 1000 grain weight was observed in four F2 populations.
High heritability coupled with high genetic advances was observed for panicle
weight and grain yield in all the six populations indicating the role of
additive gene action. Whereas, high heritability with low to moderate genetic
advance in all the six segregating population for 1000 grain weight was
observed, indicating the presence of both additive and non-additive gene
action in the expression of these traits. Hence, simple selection for the
traits like panicle weight, 1000 grain weight and grain yield would be
sufficient to bring genetic improvement in the desired direction. Key words: Sorghum,

Abstract: Genetic diversity
is indispensable to sustain genetic gain in breeding programmes. Present
investigation in search of genetically diverse clones was conducted in
Randomized complete block design (RCBD) with two replications at Zonal
Agriculture Research Station (ZARS), Vishweshwaraiah
Canal Farm, Mandya, Karnataka,
India. Based on Mahalanobis D2 statistic
thirty five clones were grouped into eight clusters of which, cluster III was
the largest followed by cluster V with 15 and 10 genotypes, respectively.
Higher inter-cluster distance was noticed between cluster V and VII (21.439)
indicating high genetic diversity among two clusters. Thus, exploitation of
genotypes of these two clusters as parents for crossing could produce good segregants. Lower inter cluster distance between cluster
II and IV (6.214) and intra cluster distance within cluster II (3.523) and I
(3.742) was noticed to indicate the close relationship of genotypes within
each of these clusters. Commercial cane sugar (CCS) yield (t/ha) followed by pol per cent juice and single cane weight contributed the
highest whereas, CCS (%) contributed least towards the divergence. High
cluster mean value for juice quality was exhibited by cluster VIII and IV
whereas for cane yield and sugar yield, cluster VI was the best. It has been
suggested that genotypes within these clusters could show greater
potentiality for breeding purpose by virtue of their desirable characters. Key words: Sugarcane,

Abstract: We aimed to assess
two different polymersviz., cellulose andstarch for
preparation of riceendophytic formulations. Six
previously isolated rice endophytic bacteria were
characterized and identified as Paenibacillus
isolates (K4, K15, N1 and Y2), Pseudomonas
isolates (K23 and G) and RhizobiumCOG5
was used as reference strain. Among the isolates, reference strain RhizobiumCOG5 showed maximum nitrogenase activity (52 n moles ml-1 h-1).Paenibacillus isolate K15 produced
maximum amount of indole acetic acid (IAA) (21.5 mg
100 ml-1) and cytokinin(12.5 ng ml-1) whereas Pseudomonas isolate G
produced maximum amount of gibberellic acid (11.60
µg ml-1). Polymer based carrier formulations were prepared by
using cellulose and starch. Population in polymer based formulations was
maintained at 108cfug-1
whereas in lignite it was maintained up to 107cfug-1.Among
the cellulose and starch polymer formulations evaluated, cellulose was found
to be the best carrier for rice endophytes.Among
the treatments, cellulose blended formulation promote higher vigour index and dry matter production (2.5 mg seedling-1)
followed by starch blends. Key words:Bacterial rice endophytes, Carrier, Cellulose, Starch, Biofertilizer |

Abstract: To increase salt tolerance
maintenance of low concentration ofNa+
then K+ and high K+/Na+ratio is very
important for enzymatic activity and other cellular activity. NHX1
transgenic ricehave this capacity to maintain high
K+/Na+ ratio. To know this NHX1 trasgenic and wildtype rice
plants are exposed to 350mM NaCl by hydroponic
method. Sodium and Potassium content was estimated by the ICP- OES. Root andleafsamples were used for estimation. Na+
and K+ content was expressed in m. mol/g
of dry weight. After 45 days of treatment data revealed that there was
significant difference in the Na+ and K+ concentration
of root (In wildtype: Na+ concentration
was 137.2 mM g-1 of dry weight and
K+ concentration was 94.09 mM g-1
of dry weight; in transgenic line: Na+ concentration was
40.56 mM g-1 of dry weight and K+
concentration was 115.81 mM g-1 of dry
weight) and shoot (In wildtype: Na+ concentration
was 195.00 mM g-1 of dry weight
and K+ concentration was 251.10 mM g-1
of dry weight; in transgenic line: Na+ concentration was
114.20 mM g-1 of dry weight and K+
concentration was 291.60 mM g-1 of dry
weight). Even though transgenics had higher
concentration of Na+they showed tolerance to salt stress because
these transgenics have mechanism of compartmentation through pgNHX1 gene, this mechanism
was absent in wildtype. The K+
concentration was higher in roots of transgenics
compared to wildtype. The K+/ Na+
ratio in the roots (0.90) and shoots (2.55) of transgenics
was higher compared to wild type (0.68 in root and 1.28 in shoot). This
showed that transgenics have maintained ion
homeostasis under salt stress by sequestering the toxic Na+ into
the vacuoles. The production of ROS and the cells ability to scavengeis considered as critical features of stress
tolerance. Wildtype under stress condition had
produced more H2O2 compared to transgenic lines. This suggest that transgenic plant cells have ability to
scavenge the ROS. Key word: Compartmentation, ICP-OES, NHX1

Abstract:A study was under
taken during 2011-12 on the comparative assessment of water stable aggregates
(WSA), aggregate ratio (AR), Mean weight diameter (MWD) of aggregates,
aggregates associated organic carbon and total nitrogen status in native and
cultivated surface soils under eight major crops. Irrespective of crops
native soils exhibited higher per cent of macro-WSA (>0.25 mm) as compared
to corresponding cultivated soils as was reflected in mean aggregate ratios
(AR) varying from 2.76 to 7.04 in cultivated and 4.43 to 10.48 in native
soils. MWD of WSA for native and cultivated soils of research farms varied
from 1.35 - 2.37 mm and 0.84 - 2.10 mm, respectively. Cultivated soil AR was
of the order: Bardoli-wheat > Vyara-rice > Paria-sapota
> Surat-sorghum > Navsari-sugarcane
> Paria-mango > Vanarasi-soybean
> Surat-cotton. MWD was considered as degree of
suitability for good agriculture. Accordingly the order was:Bardoli-wheat > Paria-sapota
> Paria-mango > Vyara-rice
> Navsari-sugarcane > Surat-sorghum
> Vanarasi-soybean > Surat-cotton.
Native soils analyzed higher WSA-associated-organic carbon (WSA-OC)
over cultivated soils in all the size fractions (>2.0, 1.0 - 2.0, 0.5 -
1.0, 0.25 - 0.5 and < 0.25 mm). WSA-organic carbon (OC) and total nitrogen
(TN) did not follow any definite trendas to varying
aggregate –sizes for both native and cultivated soils. Micro-aggregates (<
0.25 mm)- stored OC was considered asthe measure ofstable or sequestered OC and based on that, research
farms were of the following order: Surat-cotton

Abstract:The present study was
undertaken to identify the stable genotypes for grain yield and its
components traits with desirable performance under three varying temperature
regimes taking 20 diverse wheat genotypes planted under three microenvironments
during Rabi 2012-2013. Pooled analysis of variance revealed
significant variance due to environment for all traits indicating thereby
differential response of all the genotypes. The combined analysis of variance
depicted significant G x E interaction for all the characters under study
indicating substantial amount of predictable G × E interaction. For grain
yield, two genotypes (NW 1014 and K 9162) exhibited stable performance across
the environments based on their superior mean performance, regression
coefficient (b) close to unity and non significant deviations from
regression. Genotype K 612 showed superior mean performance, had regression
coefficient greater than unity with non-significant deviation from regression
coefficient and thus was found suitable for favorable conditions. Whereas, genotypeK 9162 was the highest yielding and stable
genotype along with early maturity (118 days) and has potential for late
planting conditions and may also be utilized for hybridization programme to improve yield and reduce crop duration in
wheat. Key words: Bread wheat,

Abstract:Among the major causes
of soil degradation in India, water erosion is considered to be the most
severe one which covers almost 68.39 % of the affected area resulting into
the annual soil loss of about 5.3 billion tons through erosion.In
the present study an attempt has been made to measure and model the water
erosion to identify priority of micro-watersheds for watershed management
planning of study area using the ArcGIS interface.
Sub-watershed (5D1A5c) that catches water from main stream of Dediapada region (Dist.-Narmada, Gujarat) was selected
for the study purpose. The sub-watershed covers 7 micro-watersheds i. e. d, e, f, g, h, j and k. Revised Universal Soil Loss
Equation (RUSLE) was used to estimate cell wise gross soil erosion of study
area. The parameters of RUSLE were estimated separately by adopting standard
procedure. The erosion susceptibility map was derived using gross erosion
rate and soil loss tolerance limit of the study area using standard formula.
Two different approaches were adopted for prioritization of micro-watersheds.
In the first approach, gross erosion values of each micro-watershed were
arranged in descending order to decide the priority of micro-watersheds while
in second approach, the priority of micro-watersheds was decided based
on the highest area under very high priority (> 35 ton/ha/yr) with lowest
area under safe zone (< 0 ton/ha/yr) for each micro-watershed. The
prioritization of micro-watersheds from both the approaches gives same
priority. The priorities of micro-watersheds were decided as d, g, j k, e, f
and h for micro-watershed planning, execution and management program. Key word: Prioritization of

Abstract: A six parent diallel cross of pumpkin revealed contribution of both
additive and non-additive gene action controlling the expression of yield and
its components. The Combining ability study was carried out at Kittur Rani Channama
College of Horticulture, Arabhavi, Karnataka, Epistasis was pronounced for all the characters. Among
parents, KP-31 and KP-51 ranked as top general combiners for yield and its
components. Higher yield was associated with increased number of fruits
KP-51(0.30), average fruit weight KP-31(0.54), fruit length KP-51(2.03) and
fruit diameter KP-31(4.21). Good specific combination involved high × low
general combiners. Exploitation of heterosis
appeared to be limited. Three crosses KP-31× KP-26, KP-17×Arabhavi local and

and magnitude of genetic divergence using Mahalanobis
D2 Statistics. The data for ten important traits recorded from the
genotypes raised in Randomized Complete Block Design (RCBD) with three
replications. The thirty green gram genotypes were grouped into five
clusters. Cluster V contained the highest number of fourteen genotypes
followed by cluster III and IV with has five-five genotypes. The patterns of
distribution of genotypes from different geographical location into five
clusters were random, demonstrating that geographical isolation may not be
the only factor causing genetic diversity. The highest intra-cluster distance
was observed for cluster V (1.506) and the lowest intra-cluster distance was
observed for cluster I (0.759). While the highest inter-cluster distance was
observed between cluster II and IV (7.677) and the lowest inter-cluster
distance was observed between cluster I and V (2.664). The cluster IV has
high mean value for days to 50% flowering (69.07), plant height (50.31), days
to maturity (100.07), number of pods per cluster (4.02), number of seeds per
pod (11.09) and seed yield per plant (5.31). Thus genotypes of these clusters

Abstract: The study was
conducted to assess the genetic diversity among 40 genotypes of bread wheat (Triticum aestivum
L.). The genetic diversity analysis revealed the formation of 13 clusters
suggesting the presence of wide genetic diversity. The clustering pattern
indicated that geographic diversity was not associated with genetic
diversity. The analysis of per cent contribution of various characters
towards the expression of total genetic divergence indicated that grain yield
per plant followed by length of main spike, number of effective tillers per
plant, plant height, number of grains per main spike and grain filling period
contributed maximum towards total genetic divergence. Based on the maximum
genetic distance, it is advisable to attempt crossing of the genotypes from
cluster XII with the genotypes of cluster X, which may lead to the generation
of broad spectrum of favourable genetic variability
for yield improvement in bread wheat. Key words: Genetic divergence,
