Abstract: The present work
entitled was conducted in biochemistry, Department of Chemistry, Sam Higginbottom Institute of Agricultural, Technology and
Sciences, (Formerly Allahabad Agricultural Institute) (U. P) to evaluate
studies on Physico-chemical and microbiological
characteristics of sewage discharged in Yamuna river and bioaccumulation of
selected heavy metals in cucurbits family crop as sponge gourd (Luffa aegyptica Roem). The present study was conducted to
assess the heavy metals (Cu, Fe, Zn and Ni) concentration of cucurbits family
vegetable sponge guard irrigated with untreated sewage waste water in around
Yamuna river bank of Allahabad district. The field experiment was laid out in
two way classification of Randomized block design with three replications.
For securing maximum concentration of Cu, Fe, Zn, and Ni (mg/l) in sewage
waste water and Yamuna water was observed in site T2 Gau-Ghat (Nala No. 2) compare
than other two sites Gau-Ghat (Nala
No. 1) and Baluaghat (Chachar
Nala). The study showed that the concentration of
Cu, Fe, Zn, and Ni (mg/l) in sewage and Yamuna water varied greatly in (P4
) sewage waste water compare than other three places as (P1)
Upstream, (P2) Down stream and (P3)
Mixing point sewage waste water. In case of season maximum concentration was
observed in all four heavy metals in summer season compare than other two season as winter and monsoon. The highest concentration of
heavy metals in soil (Cu, Fe, Zn and Ni ppm) was
observed in site as T2 Gau-Ghat (Nala No. 2) as well as in plant after irrigated the
sponge gourd with untreated sewage waste water of Yamuna river from different
two sites of Allahabad as Gau-Ghat (Nala No. 1) and Baluaghat (Chachar Nala). Soils polluted
with heavy metals have become common across the globe due to increase in
geologic and anthropogenic activities. Plants growing on these soils show a
reduction in growth, performance and yield. Sewage waste water irrigation
applies for crop is an effective method of treating heavy metal polluted
soils. It has essential nutrients for soil fertility and productivity. Key

Abstract: Eighty one rice
genotypes (Oryza sativa L.) were
evaluated during Kharif, 2010 for thirteen
quantitative traits to examine the nature and magnitude of variability,
heritability (broad sense) and genetic advance. Analysis of variance revealed
that the differences among eighty one genotypes were significant for all the
characters. Among all the traits number of panicles per hill (26.00)
exhibited highest estimates of genotypic coefficient of variation (GCV) and
number of tillers per hill (27.37) exhibited highest phenotypic coefficient
of variation (PCV) followed by number of spikelets
per panicle (24.84), grain yield per hill (19.23), Harvest index (19.33) and
Biological yield (17.75). Broad sense heritability was highest for biological
yield per hill (99.96), which suggested that this trait would respond to
selection owing their high genetic variability and transmissibility. Maximum
genetic advance as percent of mean was recorded for number of tillers per
hill (96.38) with high value of heritability. Key

Abstract: Antioxidants are
man-made or natural substances that may prevent or delay some types of cell
damage. Antioxidants are found in many foods, including fruits and vegetables.
Although oxidation reactions are crucial for life, they can also be damaging;
plants and animals maintain complex systems of multiple types of
antioxidants, such as glutathione, vitamin C, vitamin A, and vitamin E as
well as enzymes such as catalase, superoxide
dismutase and various peroxides. Traditional herbal medicines, dietary foods
were the main source of antioxidant for ancient peoples that protected them
from the damage caused by free radicals. Antioxidants are widely used in
dietary supplements and have been investigated for the prevention of diseases
such as cancer, coronary heart disease and even altitude sickness. Although
initial studies suggested that antioxidant supplements might promote health,
later large clinical trials of antioxidant supplements including
beta-carotene, vitamin A, and vitamin E singly or in different combinations
suggest that supplementation has no effect on mortality or possibly increases
it. These are also use in the food industry in the form of preservatives in
foods and cosmetics and to prevent the degradation to rubber and gasoline. Key

On the basis of genetic distance, these genotypes were grouped in to 8
clusters. Cluster-I was largest, consisting of 17 genotypes, while remaining
clusters II, III, IV, V, VI, VII and VIII included one genotype each.
Clustering was mainly due to either geographical locations or due to
genotype. Among 18 characters included for D2 analysis, vitamin C
content (71.01%) contributed maximum towards expression of genetic divergence
followed by fruit flesh thickness (20.65%), fruit cavity size (3.99%), and
leaf area (1.88%). The inter cluster distance (97.23) was highest between the
clusters III and VIII. Thus, the genotypes from these clusters may be used as

was collected from the respective industry administrators/workers of the
knitting industry and by personal observation. The study revealed that the
knitting industry is a unique and distinct part of the textile industry and
is one of the oldest industries in India and knitwear constitutes major
proportion of the total garments exports from India.Analysis
of data reveals that majority of knitting industry workers were belonging to
age group 30-35 years, illiterate, Muslim and OBC category with poor economic
status. They were performing industry work about 7-8 hours all the seven days
in week. They earn about Rs. 10,000/- month and majority were having 15-20
years of experience. Most of respondents reported that the working
environment was unsafe and unhealthy and also found occurrence of various
health problems due to poor ergonomic conditions. The study reported that
Industry temperature, low light, humid industry environment and machinery
noise was also higher than recommended value. Workers also exposed to various
biological hazards due to unhygienic condition at workplace. Knowledge
regarding work posture, pattern, environment, safe work methods and proper
postures can help reduce risk of many health hazards. It can be a very
effective way of empowering the industry to mitigate occupational health
hazards in knitting industry. Key

Abstract: Study on viability
of sub surface drip irrigation in sugarcane was conductedin
different farmers field of bhadra
command area of Davangere district. Treatments
comprised of T1- without paired row planting + rec.NPK (based on
soil test), T2- paired row planting + rec.NPK (based on soil
test), T3- paired row with sub surface drip + rec.NPK (based on
soil test), T4- farmers practices,T5
– paired row with sub surface drip+ 19:19:19 N: P: K 30 kg / ha as soil
application and T6 – control.The results
revealed that paired row with sub surface drip irrigation gave the highest
cane yield of 220 t ha-1 followed by paired row planting + rec.NPK
(160 t ha-1) and lowest yield obtained in control (80 t ha-1).
Similarly water use was 145 ha cm in case of sub surface drip irrigation,
followed by paired row surface irrigation of 165 ha cm and highest was 296 ha
cm in case of farmers practices with normal planting. The water productivity
of sugarcane with sub surface drip irrigation was 1517 kg ha cm-1
where as under farmers practice with normal planting was only 416 kg ha cm-1.Thus,
the sugarcane production and water productivity was enhanced by 78.9 and 265
per cent respectively with sub surface drip irrigation. Key

Abstract: The treatments
comprised of growth regulators viz., NAA (40, 50 and 60 ppm), GA3 (25, 50 and 100 ppm)
and Paclobutrazol (100, 150 and 200 ppm) and distilled water spray as control. The growth
regulators tried in this investigation failed to bring about any significant
change in plant height, number of secondary branches and days to first flower
appearance and 50% flowering. Application of GA3 at 100 ppm resulted in maximum number of primary branches and
secondary branches in main and ratoon crop
respectively which was significantly higher compared to control. The plant
spread was also improved by GA3 at 50 and 100 ppm
during main and ratoon crops respectively, while
NAA at 50 ppm resulted in early flowering in both
main and ratoon crops of kalmegh.
Maximum leaf area was recorded both in main and ratoon
crop of kalmegh due to GA3 application
at 100 and 50 ppm respectively.
Fresh and dry weight of leaf, stem and their total biomass were significantly
influenced by all the growth regulator treatments, wherein, paclobutrazol at 100 ppm
registered maximum values.The foliar application of
NAA at 50 ppm was very effective and recorded
maximum cumulative dry herb yield and drying percentage. Key

problem causing environmental pollution. Reutilization of these biological
wastes for unconventional source of food, oil and medicinal uses could be
performed after determining there nutritive and
biochemical properties. Mango seed despite of its beneficial characters is
treated as wastecreating environmental menaces. In
the light of the present facts the present investigation was carried out
during year 2012-2013. Mangoes were collected from local market. Seeds were
separated from fruit, washed thoroughly with tap water, shade and sun dried.
The kernels were removed from their tenacious leathery coat. Then they are
finely ground into kernel flour. De-fatted mango kernel powder was analyzed
for parameters like carbohydrate, protein, crude fiber and ash. Carbohydrate
content obtained in mango kernel was reported as 46.85 % which was comparable
to other traditional animal meal.The fat content
obtained from mango kernel was 12.39 % is quite good to utilizes mango kernel
powder as non-conventional source of fat extraction.Therefore, it
could be utilized as feed stuff for animals and non-conventional source of

Abstract: Pre harvest
bagging of mango fruits to avoid adverse effect of sudden fluctuations in the
temperature, fog, un seasonal rainfall etc., on fruit by causing
physical damage. The experiment was undertaken to study the effect of pre
harvest bagging on fruit quality and shelf life in mango. The results
indicated that various chemical parameters were affected significantly due to
bagging. The fruits of treatment T6 had maximum TSS (17.61 0B),
- carotene (12164.33 µg /100 g) and ranked first for sensory
evaluation at ripe. Reducing sugar (2.82%) and total sugar (9.65%) was maximum in T5. Treatment T1 showed
best performance for ascorbic acid (79.44 mg/100 g) content of fruit. T4
contributed best performance for reducing sugar (1.32%), total sugar (2.26%)
and - carotene (317.9 µg /100 g) at harvest. Bagging had significant
effect on spongy tissue incidence and stem end rot. The fruits of T1
and T2 showed best performance in shelf life (17 days) and no
incidence of spongy tissue. Thus, it was concluded that bagging prior to
harvest has improved fruit quality, shelf life and decreased disease
incidence. Key

Abstract: The present study
has been carried out for the development of pre-harvest forecast model of
rice at district level on the basis of weather variables. Weekly data of 14
meteorological weeks on seven weather variables under rice crop season over a
span of 21years period (1989-90 to 2009-10) have been used along with the
annual rice production data for Faizabad district
of eastern Uttar Pradesh. Generated weather variable (56 weighted, unweighted and joint +1 Time trend) has used under the
stepwise regression to screen out the important weather variables and
multiple regression approach was subsequently employed to estimate model
parameters. Q140 (unweighted interaction
between maximum temperature and rainfall and Q451 (Weighted
interaction between rainfall and Wind velocity) and time trend comes out to
be most significant weather variables for forecasting of rice yield. The
proposed model contains combination of weighted and unweighted
weather variables and explains 76% (significant at 1% level of significance)
of the variability of rice production in terms of R2. The model
has been developed for 19 years data and validated for 2 years data.
Predicted yield for the 2009 is 23.765 and 2010 is 24.31 with deviation
0.021% and -5.69 % respectively, RMSE (1.498) for the model is also

objectives to assess variability, heritability and genetic advance for
quantitative characters Experimental material for the study was consisted of
46 genotypes of eggplant pertaining to four groups including five checks (Arka Nidhi, NDB-2, SM-6-6 Pant Rituraj and KS-224). The experiment was conducted in
Randomized Complete Block Design with three replications. Each treatment
consisted of 20 plants in two rows, having spacing of 60x45cm with net plot
size of 4.5x1.2m2. Observations were recorded on 11 quantitative
characters viz., days to 50% flowering, primary branches per plant,
plant height (cm), fruit weight (g), fruit circumference (cm), flowers per
inflorescence, fruit length (cm), fruits per plant, marketable fruit yield
per plant (kg), unmarketable fruit yield per plant (kg) and total fruit yield
per plant (kg).The analysis of variance for the design of experiment
indicated highly significant differences among the genotypes for all the
traits. Based on mean performance of genotypes NDB-216 for long purple and
NDB-252 for round purple fruit were found as most promising genotypes for
total fruit yield per plant. High magnitude of variability (GCV and PCV) was
observed in case of unmarketable fruit yield per plant followed by fruit
circumference, marketable fruit yield per plant, fruits per plant, total
fruit yield per plant and primary branches per plant. Days to 50% flowering
exhibited low value of variability. High heritability coupled with high
genetic advance in percent of mean were recorded

Abstract: The progressive
decrease of fresh water resources is leading towards the inevitable use of
saline water for irrigation purpose. With using saline waters for irrigation,
there is need to undertake appropriate management practices to prevent the
development of excessive soil salinization for crop
production. A field experiment was carried out to investigate the effect of
saline water irrigation and management practices on uptake of primary and
secondary nutrients. At harvest, the significantly highest total N, K, S and
Mg uptake was recorded by C2-FYM, followed by C3-FYM
and C3/C4-FYM. Regarding P and Ca total uptake, among
water quality levels, the significantly highest uptake was recorded by C2
water followed by C3 water and alternate irrigation with C3/C4
water. Among management practices, significantly the highest total P and Ca
uptake was recorded by FYM application, followed by green manure treatment.
However, the interaction effect was found to be non significant in case of P
and Ca uptake. Key

Abstract: Medicinal plants
are very important as they have been used for prevention or treatment of many
diseases. Therefore, this study was focused on the effect of irrigation
frequency [Daily (=Control), 7, 14 and 21days interval] on morpho-physiological and biochemical aspects in four
different medicinal plant species viz., Cassia tora
Linn., Andrographis
paniculata Nees., Wedelia calendulacea Linn.
and Stevia rebaudiana (Bertoni) Bertoniduring summer season. These parameters including
plant height; number of leaves & branches; dry weight; chlorophyll, carotenoid & total protein content which were reduced
significantly as increasing stress level, while proline
content enhanced. Maximum height (99.00 cm) and total dry weight (14.70 gm)
recorded in C. tora; number of leaves
(102.66) and branches (31.33) in S. rebaudiana,
while per cent reduction in aspects of height (62.95%) and total dry weight
(84.83 %) was maximum in W. calendulacea; in
aspect of leaves and branches in C. tora (67.24%)
and S. rebaudiana (78.72%) respectively.
Maximum per cent reduction in chlorophyll, carotenoid
and total protein was recorded in A. paniculata
(68.95%), S. rebaudiana (74.64%) and S. rebaudiana (55.70%) respectively. Thus these results
indicate that such species are more susceptible/intolerant
to water stress as compared to rest of the species. The per cent stimulation
in proline content under
21 days watering frequency was highest in W. calendulacea
(81.22%) as compared to other species. This result reveal that W. calendulacea is more stress tolerant/resistant to
water stress as compared to other selected species. Key

dose of nitrogen) in both direct seeded (30.4) and transplanted rice (30.7)
system at harvest. The NDVI readings at panicle initiation recorded highest
in JKPH 3333 under transplanted rice (0.63) compared to direct seeded rice
(0.60). Among varieties BPT-5204 and Gangavathisona
at 90 DAS had relatively lower NDVI values in DSR (0.59)as
compared to TPR (0.62). The relative water content at panicle initiation was
more in JKPH 3333 (89.43%) at 125% RND compared to other varieties and
planting methods. Among methods of planting at 125% dose of nitrogen TPR
(56.29 q-1ha) recorded highest yield compared to DSR (42.97 q ha-1).At
75% and 100% nitrogen, yields were significantly lower (38.90 q ha-1
and 44.25q ha-1) under DSR compared to TPR. The study suggest that
the maintenance of greenness of canopy over longer period and chlorophyll
content after panicle initiation had greater influence on yields under
transplanted rice cultivation to that of direct seeded rice.The
study also reveals that, itis important to maintain
the critical amount of plant nitrogen throughout the vegetative and
reproductive phases for better yields in direct seeded rice. Key

Abstract: Ten genotypes and
their forty five crosses of Mustard were evaluated in Randomized Block Design
(RBD) with three replications for yield and yield contributing traits during
2011-2012 to find out genetic variability, heritability and genetic advance
in per cent of mean. Analysis of variance for the design of experiment showed
significant for all the twelve characters. The magnitude of phenotypic
coefficient of variation was higher than genotypic coefficient of variation
for all the characters in both timely sown (E1) and late sown (E2)
conditions. The higher estimates of phenotypic coefficient of variation
(>20%) were recorded for number of secondary branches per plant in both
timely sown (E1) and late sown (E2) conditions and GCV
and ECV was high for this character in timely sown (E1), while
number of primary branches per plant in timely sown (E1).The high
heritability estimates in narrow sense were recorded for days to 50%
flowering, days to maturity and 1000-seed weight, in E1 and E2
while oil content only in E1. Genetic advance in per cent of mean
was found to be high for secondary branches per plant (26.84%,26.82%), number
of siliquae on main raceme (24.36%,22.69%)
1000-seed weight (28.09%,41.77%), biological yield/plant (32.33%,32.65%),

Abstract: Genetic analysis
was carried out for 55 diverse rice genotypes (10 parents and 45 F1s)
through half-diallel mating design during kharif season 2011-2012 and 2012-2013. The
analysis of variance showed highly significant differences among the
treatments for all the 19 traits under study. High heritability (broad sense)
coupled with high genetic advance was observed for number of grains per
panicle, harvest index, grain yield per plant, productive tillers per plant,
plant height, biological yield per plant, kernel length after cooking
indicating selection will be 100 percent effective based on these traits
because they were under the influence of additive and additive x additive
type of gene action. Highest coefficient of variation (GCV & PCV) was
recorded for plant height (13.85 % & 13.87 %), productive tillers per
plant (14.58 % &15.13%), number of grains per panicle (17.93 % &18.07
%), biological yield per plant (12.67 % & 12.71 %), grain yield per plant
(15.88 % & 15 97 %), harvest index (16.80 % & 16.90 %) and kernel
length after cooking (10.09 % & 10.19 %), indicating that these traits
are under the major influence of genetic control. The traits, panicle length
(gr=0.31** & pr=0.30**), number of grain per
panicle (gr=0.80** & pr=0.79** ), biological
yield per plant (gr=0.31** & pr=0.30** ) and
harvest index (gr=0.67** & pr=0.67** ) had positiveand significant correlation with grain yield per
plant and these traits also had highest positive direct effects on grain
yield therefore the above mentioned traits contributed maximum to higher
grain yield compared to other traits indicating that we can improve grain yield
by improving these traits as well as emphasis should be given based on these
traits for the selection of elite genotypes from the segregating generation. Key

Abstract: The Line x Tester
analysis was done with six lines and four testers of ridge gourd to study the
heterosis and combining ability effects for growth,
yield and yield attributing traits. The lines found to be good general
combiners were L4 (12.18) and L5 (11.56)
for vine length; L4 for number of branches (0.54) and
number of leaves per vine (6.42), total chlorophyll content (0.05), average
fruit weight (20.49), proline content (12.91), leaf
area (41.61) and total fruit yield per vine (139.24); L3
(-4.82) and L4 (-2.60) for days to 50% flowering and days
to first harvest. The best specific combiner for vine length was L5
x T2 (33.69). For numbers of leaves (6.32) and leaf area
(41.82) the specific combiner was L4 x T2.
The hybrid L2 x T4 was earliest as it was
specific combiner for days to 50% flowering (-3.53). Highly positive
significant heterosis was observed for number
fruits per vine (25.00%), total chlorophyll content of leaf (84.01%), leaf
area (235.07%) and total fruit yield per vine (58.5%). Highly negative
significant heterosis was observed with the days to
50% flowering (-15.38%) over the better parents. Three hybrids possessed
significantly useful heterobeltiosis for fruit
weight. Key
