Abstract: For centuries the aloe
vera plant has been known for its medicinal
properties. It is proposed to be of benefit for the digestive and immune
systems, as well as having healing effects on the skin. Chemical constituents
of sea buckthorn berries are under research due to positive effect in
inflammatory disorders, cancer mechanisms and on bone marrow after chemotherapy.The present study was undertaken to develop
a ready to serve (RTS) beverage using Aloe vera
gel and sea buckthorn berries. Aloe vera gel
(25%), sea buckthorn berry juice (30%), sugar (25%), and citric acid (0.1%)
were mixed to prepare the blend with TSS of 130Brix.
The product was bottled, pasteurized, and stored at room temperature. The
quality characteristics and storage stability of the berry juice aloe gel
beverage (BJAB) was compared with berry juice (BJ). Time-dependent analysis
was carried out up to four months for various physicochemical parameters,
antioxidant profile, microbial quality and sensory acceptability. The BJAB
exhibited superior quality characteristics compared to BJ when compared as in
fresh condition and in stored samples. The BJ was acceptable up to three
months whereas BJAB for four months. The results indicate that nutraceutical rich aloe gel and berry juice can be
utilized to develop nutritional and tasty functional fruit beverage with
improved quality. Key words : Sea

Abstract: The research was
conducted to fabricate and develop an advanced solar tunnel dryer (STD) for
the drying of fruits, vegetables and medicinal plants. The system was designed
as a portable system for decentralized applications at various sites to
satisfy the drying requirements of small farmers and co-operatives. The cross
sectional area of the solar tunnel dryer was trapezoidal in shape having
0.1225 m2 face area, with length and width of four meters and one
and half meter respectively. It comprises a collector section (2 m) long and
a drying section (2 m long) and one electric powered fan to provide the
required air flow rate over the perishable agricultural products to be dried.
Transparent polythene cover was used to close the dryer on top side to
maintain the steady state air flow within the dryer. It has been observed
that the drying air temperature was easily raised by some 8-14°C above the
ambient temperature at air velocity ranges 0-1 ms-1. The process
curves were found similar to a conventional dryer showing that this dryer can
be successfully utilized for the drying of agricultural products using solar

Abstract: Genetic variability,
heritability, genetic advance and its per cent over mean for eighteen
characters were assessed by field evaluation of twenty–four wild melon
genotypes at College of Horticulture, Bagalkot , Karnataka during 2013-14. High degree of
variation was observed for all characters. The difference between phenotypic
co–efficient of variation (PCV) and genotypic co–efficient of variation (GCV)
are found to be narrow for most of the traits. However, high GCV and PCV was
observed for leaf area, number of fruits per vine, average fruit weight, fruit
length, fruit breadth, yield per vine, fruit cavity size, number of seeds per
fruit, fruit flesh thickness, TSS, vitamin–C and seed to pulp ratio. High
heritability coupled with high genetic advance recorded for vine length, leaf
area, node at first female flowering, node at first male flowering, number of
fruits per vine, average fruit weight, fruit length, fruit breadth, yield per
vine, fruit cavity size, fruit flesh thickness and number of seeds per fruitare indicates the predominance of additive gene
action. Hence, improvement of these traits through simple selection breeding
method for improvement of wild melon would be rewarding. Key words:Wild

Abstract: India is an
agricultural country, and hence a lot of water is required for farming. Water
should be used in a proper way. In this paper is presented the “Wireless
Sensor Network based Automatic Drip Irrigation Management’’. An automation of
irrigation systems has several positive effects. Once installed, the water
distribution on fields or small-scale gardens is easier and does not have to
be permanently controlled by an operator.In this
paper we are giving brief outline of improving Throughput and Average end to
end delay of information gathered from the agriculture field for Precision
Agriculture. This system provide delivery of water level information signals
to base station as it also computes a threshold as well as does calculates
values based on transmission range. This over all computational mechanism
helps us to build a robust mechanism for delivery of information to base
station thus reducing the packet loss. A Wireless Sensor Network is a system
consisting of radio frequency transceivers, sensors, microcontrollers and
power sources. Recent advances in wireless sensor networking technology have
led to the development of low cost, low power, multifunctional sensor nodes.
Sensor nodes enable environment sensing together with data processing.
Sensors are able to network with other sensor systems and exchange data with
external users. Sensor networks are used for a variety of applications,
including wireless data acquisition, environmental monitoring, irrigation
management, safety management, and in many other areas. Keywords:Wireless

Abstract: Biology and morphometrics on lace bug Urentius
hystricellus (R.) (Tingidae:
Hemiptera) in off season pigeonpea
under controlled condition (26 ± 1 °C temperature, 14:10 L:D photoperiod and
60 ± 10% RH) revealed that five nymphal instarstook 13.6 ± 1.96 days to enter into adult stage
(5.7 ± 0.97 days) with pre-oviposition and
incubation period of 2.9 ± 0.74 and 6.3 ± 1.49 days respectively. Final
metamorphosis stage of tinged bugs is very characteristic densely reticulated
body surface and hemelytra. The total life cycle of lacewing bug observed
28.5±9.67 (4 to 5 weeks) days.Morphometric studies
revealed that, mean length and width of eggs were measured about 0.45±0.014
mm and 0.16±0.014 mm respectively. However, among five nymphal
instars, first nymphal instar
of mean length and width was measured about 0.52±0.033 mm and 0.19±0.016mm
respectively. Mean length and width of adult was measured about 0.35±0.075 mm
and 0.86±0.016 respectively. The incidence of tinged bug pest population
recorded in off season pigeonpea plants from 5th May to 5th
July revealed that, there was maximum population recorded in the hotter
months during May and June on an average of 29 to 44 nymphs and adults per 3
leaves at bottom, middle and top. This was positively correlated with Maximum
temperature (r= +0.442). However, in July month drastic reduction of
population was observed on an average of 18 nymphs and adults from bottom,
middle and top leaves (3 leaves). This shows that, pest population was
negatively correlated with minimum temperature (r= -0.288) and in later
months the population was almost declined. Key words: Urentius hystricellus, Biology, Incidence, Off seasonal pigeonpea |

reduction in grain yield (66.07 %) over weed free check. The lower weed
density and dry weight and higher value of germination are yieldattributes as well as grain yield (25.39qha-1)were recorded under 60 kgha-1
seed rate. Post-emergence application of bispyribac-sodium
@ 25 g ha-1 applier at 30 DAS, recorded higher grain yield of rice
(24.45qha-1) followed by Pendimethalin @
1.0 kg ha-1 (PE) reducing population & dry matter of weeds and
it lead to highest grain yield which ultimately fetched highest net return. Keywords: Rice, Seed rate,

Abstract:Effect
of collar rot fungus, Aspergillus niger on seed germination and seedling vigour of groundnut genotypes was studied.In
vitro experiment was conducted at the Department of Seed Science and
Technology and in screen house of Department of Plant Pathology, CCS Haryana
Agricultural University. Significant per cent reduction in plumule and radical length, fresh and dry weight
including vigour index between inoculated and
un-inoculated seeds with A. niger was
observed. Similar reduction was also observed in per cent germination
which ranged between 10.52 to 20.00 per cent in comparison to un-inoculated
control. Plumule length of seedlings was
significantly reduced in vitro conditions after inoculation with the
pathogen, which ranged between 19.78 to 25.18 per cent. Similarly, the
radical length was also significantly reduced in all genotypes within a range
between 19.04 to 23.90 per cent in comparison to un-inoculated control. Fresh
and dry weight of seedlings were also reduced by inoculation of seed in Petri
plates by using blotter paper in vitro and the reduction in fresh
weight ranged between 26.59 to 34.02 per cent, while the reduction in dry
weight ranged between 26.19 to 37.93 per cent under seed inoculation

Abstract: The present
investigation was carried out during kharif
2014-15 at three locations viz., Regional Agricultural Research Station,
Lam Farm, Agricultural Research Station, JM Puram
and Agricultural College Farm, Bapatla. Seventy two
inter-specific cotton hybrids were tested over three environments to identify
the stable performing hybrids. The Eberhart and
Russell stability model analysis was carried out to study the genotype ×
environment interaction for all the fibre quality
traits along with lint yield plant-1. The variance due to
genotypes, environments (linear) was significant for all the characters
whereas, Genotypes × Env (Lin.) variance was
significant for all the traits except for fibre
elongation. The hybrid SCS 793 × GSB 40 had recorded higher grand mean with
regression coefficient nearly one and non-significant deviation from
regression (s2di) and was
found to be stable for 2.5 % span length and bundle strength over three
locations. Hence, this hybrid may be exploited commercially for cultivation
over a wide range of environments after thorough testing over number of
locations in different seasons. Key words: Inter-specific cotton

Abstract: A
field experiment was conducted for two consecutive years to evaluate
resistance in chickpea genotypes against dry root rot and stunt virus. Total
one hundred and fifty one (151) genotypes were evaluated against dry root rot
in which only JG315 showed resistant reaction. Based on the pooled incidence
data of two year experiment one hundred twenty nine entries including seventy
four Desi and fifty five Kabuli type were found
moderately resistant while fifteen genotypes consisted of eight Desi and seven Kabuli type under tolerant category.
Moreover six Desi type viz., GJG1001,
GNG2171, DC2012-4, IPC2007-13, CSJ647, RSG931 and one Kabuli type genotype
(JGK18) were found under susceptible category. A separate evaluation trial
was conducted for stunt disease and response of total one hundred fifty (158)
genotypes has assessed for disease reaction. Among evaluated entries only
GCP105 showed resistant reaction while fifty eight entries including thirty
three Desi and twenty five Kabuli type were found
under the category of moderately resistant. Total eighty five entries
included fifty five Desi and thirty Kabuli type,
eleven entries consisted of six Desi and five
Kabuli type, three entries having one Desi and two
Kabuli type were depicted as tolerant, susceptible and highly susceptible
respectively. Based on findings of both experiments eight Desi
type viz., CSJ513, G10023, JG38, GNG469, IPC2009-191, H10-41, JG40,
H10-57 and five Kabuli type viz., NBeG176, HK10-124, CSJK74,
IPCK2006-143, IPCK2009-164 were found promising against both devastating
diseases of chickpea. The information generated under both experiments can be
exploited in breeding programme for the development
of new variety having resistance against these diseases. Key words:
