Abstract: A
field experiment was conducted during kharif
2011 at Regional Horticultural Research and Extension Centre, University of
Horticultural Sciences, Bagalkot, Karnataka to
study the effect of sequential application of herbicides on weed management
in drill sown onion under rainfed condition.
Seventeen weed control treatments were tested in randomised
block design replicated thrice. All the herbicide treatments significantly
reduced dry weight of weeds over unweeded check.
Weed free check recorded significantly lower dry weight of weeds. Among the
herbicide treatments, sequential application of oxyfluorfen
0.08 kg ha-1 followed by (fb) oxyfluorfen 0.25 kg ha-1 was quite efficient
in controlling weeds which reflected through decreased weed dry weight and
increased weed control index. This herbicide treatment also recorded
significantly higher bulb yield (30.16 t ha-1), growth and yield
parameters. The weed index was also lowest in the above treatment (13.50%) as
compared to unweeded check (91.89%) and other
treatments (25.22 to 90.04%). Key words: Onion,

Abstract: To
develop the usefulness of plants as bio indicators requires an appropriate
selection of plant species which entail a highly important for a particular
situation. The present study was undertaken to evaluate air pollution
tolerance index (APTI) of five different plant species around City area and Navsari Agricultural University campus (Control). Among
the trees in the selected area Cassia fistula depicted highest APTI
value as compared to other species followed by Saraca
asoca and Sizygium
cumini and proved to be tolerant variety in the
city area as per the APTI value. However, Tectona
grandis and Terminalia catapa found to be intermediate sensitivity for the
polluted site (City area). Hence, it is recommended to plant S. asoca, S. cumini and C.
fistula trees in city / industrial area to cope
the environmental problem. The study also suggests that performance index
might be very useful in the selection of appropriate species which can be
expected to perform well for the development of green environments. Key words: Air

Abstract: Organic
farming is a holistic production system of farm management to create an
eco-system to achieve sustainable productivity. Due to the external effects
of chemicals, farmers recently practiced non-conventional bio pesticides and
fungicides in crop protection and management. In this context, the present
study had been taken up to study the determinant factors of adoption of bio
pesticide and fungicides in Erode district of Tamil Nadu. Logit
analysis revealed that education, land holding size and extension agency
contact are the most significant factors influencing adoption of bio
pesticide and fungicide usage in Erode district. Partial budgeting estimates
shows that using of bio pesticides-fungicides in rice; turmeric and sugarcane
cultivation is economically viable. From garret rank analysis it could be
concluded higher price is the major constraint in adoption of bio pesticides

Abstract: Environmental
changes in temperature, light and water leads to altered the plant gene
expression. Exposure of plants to several degrees of elevated temperatures
induces the expression of evolutionary conserved genes coding for the
synthesis of heat shock proteins (HSPs). The study of genetic variability,
heritability and genetic advance showed the highly adverse effect of heat
stress. The range of temperature between 30p C to 60p C revealed the growth
retardation in plant growth, although the temperature upto
30p C showed the normal morphology as its primary observation. The heat shock
protein of molecular weight less than 20kd and more than 70kd were the
evident of alteration in their gene expression. This observation showed that

Abstract: In
the present study, it has been observed that hog cholera was endemic in North
Eastern Region of India including Assam. Free grazing pigs were mostly
affected with acute course of the disease. The present study was also carried
out to evaluate the efficacy of different immunological tests (Fluorescent
antibody test (FAT), Sandwich Enzyme Linked Immunosorbent
Assay (S-ELISA) and Agar gel precipitation test (AGPT) for diagnosis of hog
cholera in clinical and postmortem samples. 314 suspected samples were
collected from 120 clinically affected pigs. All samples were collected from
9 outbreaks occurred in different parts of North-Eastern region of India and
processed for detection of hog cholera virus (HCV) antigen. In this study,
163 (51.91%) samples showed positive result in direct FAT test, 147 (46.81%)
samples were found positive in Sandwich ELISA test for HCV antigen and 19.74
per cent samples were found positive in AGPT test for HCV antigen. Isolation
of hog cholera virus was attempted from field samples in pig kidney-15
(PK-15) cell line.For isolation of HCV, 26 samples
such as leucocytes tonsil, Mesenteric lymph node (MLN), spleen, pancreases
and kidney were passaged in PK-15 cell line. Only
14 isolates could be detected by direct FAT and S-ELISA. Due to non cytopathic nature of virus, few blind passages were
required. Direct FAT could detect the viral antigen even in first passage
level itself while S-ELISA requires two-three passages. Hence Direct FAT and
S-ELISA were found comparable to each other for detection of hog cholera virus
in clinical, postmortem and cell cultured propagated samples. Statistical
analysis also revealed that FAT and Sandwich ELISA were competitive to each
other for HCV antigen detection and significantly (P < 0.05) different
from that of AGPT.In all the above three tests, it
was also found that tonsilar tissue/isolates
exhibited highest number of positive cases. Key words: HCV

Abstract: This
study aimed at investigating the ecological need, morphometry
and meristics, age and growth, food and feeding of
recently invaded alien Oreochromis niloticus in the Yamuna and the Ganga
River. Observed meristic characters of the
fish were similar and fixed in both the rivers while there was a slight
variation in age and growth. In general, growth rate of 2nd
year age group of fish was a little higher in the Yamuna. The gut content
analysis showed that O.niloticus predominantly
feed on phytoplanktons and poorly on zooplankton
which indicate its omnivorous nature. The calculated trophic
level of O. niloticus was 2.10 in the Ganga and 2.08 in the Yamuna River. There was a positive
correlation between length and weight of fishes in both the rivers, yet it
was slightly higher in the Yamuna River indicating better growth of O. niloticus in the Yamuna River.Gut
content analysis revealed dietary overlap with indigenous Indian major carp, Labeo rohita. The
results of this study suggested that invasion route of O. niloticus in the Ganga
River was through the Yamuna river as there was no morphometric
and meristic variations in the fish at first matuarity stage, showing any adaptive phenotypic
plasticity. Key words: River,

Abstract: Study
was conducted to evaluate the effect of keeping nutritional and functional
attributes of papaya pulp potential of whey to be used in nutritious and
health promoting beverage along with its shelf life, the study by evaluating
sensory and chemical quality of papaya pulp based whey beverage. There were paneer whey used as raw material, three level of sugar
(8%, 10% and 12%) and three level of papaya pulp (10%, 20% and 30%) used for
preparation of Papaya Pulp Based Whey Beverage. This product stored at 50
C as refrigerated temperature for four storage periods (0 day, 5 days,
10 days and 15 days). This process replicated three times. The findings of
study imply that the different levels of sugar and storage periods affect the

Abstract: The
global climate change, due to GHGs is making the nutritional security and
fruit production sustainability more difficult day by day; reasons may be
increase in temperature and variability in precipitation pattern results in abiotic stresses like heat, drought and flooding.
Horticulture, the major component of agriculture in India, is no exemption
from the threat of climate change impacts. In this era, Organic farming is
best adaptable option for mitigating climate change due to superior ability
to reduce emissions of GHGs as well as increase soil carbon sequestration an
appropriate combination of organic source of nutrients, cover crops, less
intensive tillage etc. An organic production system is designed to a)
enhance biological diversity within the whole system; b) increase soil
biological activity; c) maintain long-term soil fertility; d) recycle wastes
of plant and animal origin in order to return nutrients to the land, thus
minimizing the use of nonrenewable resources; e) rely on renewable resources
in locally organized agricultural systems; f) promote the healthy use of
soil, water, and air, as well as minimize all forms of pollution. Many
findings revealed that organic strategies are diversification of crop and an
increase of soil organic matter, which both could enhance resilience against
extreme weather events. Organic farming system reduces N2O
emissions due to lower nitrogen input and less CO2 emissions
through erosion due to better soil structure and more plant cover than
conventional system. In case of organic farming, biomass is not burned. It
reduces the CH4 and N2O emissions in comparison to
conventional agriculture, where crop residues are often burnt on the field.
Organic farming avoids these emissions, as no chemical nitrogen fertilizers
are used. In organic farming, nitrogen input stems from application of
manures and compost, or is fixed from the air by leguminous plants. Thus,
organic farming could be a vastly adaptable to climate smart horticulture,
and affords mitigation for climate change. It also provides a high degree of
diversity in the eco-system. Although remarkable, organic farming several
critical issues remain to be resolved. To begin with there is a need for more
research. Looking to the needs and importance of the organic farming, Navsari Agricultural University (NAU) has already started
cultivate horticultural crops from 2005 and have remarkably progressed in
this sector. Key wordsOrganic farming, Horticultural crops,

Abstract: Field experiment was carried out in farmers field during 2006 and 2007 at Marakadadoddi
village, Maddur taluk, Mandya (Karnataka) to study the influence of cultivars
and INM practices on yield potentiality aerobic rice. Results revealed that
significantly higher grain yield was recorded with KRH-2 hybrid rice (60.2 q
ha-1) followed by BR-2655 (55.5 q ha-1) and the lowest
grain yield was obtained with IR-30864 (50.8 q ha-1).
Significantly higher grain yield with KRH-2 hybrid rice may be due to its
superiority in yield attributes such as number of tillers (39.32), number of
productive tillers (35.38) and test weight (24.79 g) over other cultivars.
Higher nutrient uptake was observed in KRH-2 (142.76 kg nitrogen ha-1,
59.08 kg P ha-1 and 136.99 kg K ha-1) compared to other
cultivars like BR-2655 and IR-30864. The application of 50 per cent N through
inorganic fertilizer + 50 per cent N through vermicompost
(N4) was recorded significantly higher number of tillers (43.41
hill-1), productive tillers (40.24 hill-1), test weight
(25.87 g), absolute growth rate (g day-1 at 60-90 DAS) and grain
yield (63.1q ha-1) as compared to other integrated nutrient
practices. Integrated nutrient management with 50 per cent N through
inorganic fertilizer + 50 per cent N through vermicompost
(N4) resulted in higher N (151.21 kg ha-1), P (62.58 kg ha-1)
and K (146.98 kg ha-1) uptake as compared to other combinations of
N5, N3, N2 and N1.Among the
different cultivars KRH-2 recorded higher net return (Rs. 21,289 ha-1
and 1:2.33) over the BR-2655 (Rs. 18,690 ha-1 and 1:2.20)
and IR-30864 (Rs. 15,718 ha-1 and 1:2.00. Maximum net
return of Rs. 20,401 ha-1 and B:C ratio (1:2.57) were found in 100

such as Acacia mangium Wild. (Mangium) and Gmelina arborea Roxb. (Gamhar) established in July, 2001 at a spacing of 8m x 2m
and four crops such as Ananas comosus (Pineapple), Aloe vera
(Aloevera), Andrographis
paniculata (Kalmegh)
and Curcuma amada (Mangoginger)
were raised in the 1st week of July,
2011. At the end of 11th growing season,
maximum and minimum volume increment were achieved by tree species mangium with pineapple (16.53m3/ha) and gamhar with aloevera (3.54 m3/ha)
respectively. For crops, fruit of pineapple under mangium,
fresh leaves of aloevera under mangium,
dry plant of kalmegh in openand
rhizome of mangoginger in open condition were
registered maximum yield of 9981 Kg/ha, 8635 Kg/ha, 1239 Kg/haand 3300 Kg/ha respectively. Again the minimum yield of
pineapple, aloevera, kalmegh
and mangoginger were of 9106 Kg/ha under gamhar, 7095 Kg/ha in open condition, 823 Kg/ha under mangium and 1597 Kg/ha under mangium
respectively.It shows that four crops raised under mangium and gamhar based agrisilvicultural system and open condition, yield in the
trend of pineapple (9981 Kg/ha) > aloevera (8635
Kg/ha) > mangoginger (3300 Kg/ha) > kalmegh (1239 Kg/ha). Key words: Agrisilvicultural

Abstract: An
experiment was conducted during the rabi
season 2012-13 on clayey soil at Junagadh
Agricultural University, Junagadh to study the
sources and levels of sulphur fertilization on productivity
and economics of wheat (Triticum aestivum L.). Result revealed that plant growth
parameters viz., plant height at 60 DAS, dry matter accumulation at 60
DAS, number of total tillers at 60 DAS and harvest as well as yield
attributes viz., length of spike, was significantly improved when sulphur applied through gypsum. Significantly higher
grain (4785 kg ha-1) and straw (6866 kg ha-1) yields of
wheat were recorded when sulphur applied through
gypsum, however it remained at par with bentonite.
This source was also recorded higher net profit of Rs. 55616 ha-1
and B:C ratio of 2.59. Application of 30 kg S ha-1
recorded significantly higher growth parameters viz., plant height at
60 DAS and harvest, dry matter accumulation at 30, 60 DAS and at harvest, number
of total tillers at harvest and effective tillers. Among yield attributes
length of spike and number of spikelets per spike,
were recorded with application of 30 kg S ha-1 and remained at par
45 kg S ha-1. Significantly higher wheat grain (5188 kg ha-1)
and straw (7060 kg ha-1) yield were obtained with 30 kg S ha-1.
Application of sulphur at 30 kg ha-1
registered significantly maximum net profit (Rs. 58557 ha-1) which
was 72.3 and 48.6 per cent higher over levels of 15 and 45 kg S ha-1,
respectively with B:C ratio of 2.52. Key words:Wheat, Sulphur, Yield, Fertilizer and

Abstract: : A field experiment was
conducted during kharif 2013 on loamy
sand soil at Agronomy Farm, College of Agriculture, S.K.R.A.U., Bikaner to
study the effect of moisture conservation practices on pearl millet. Result
revealed that modification in surface configuration as ridge and furrow,
plastic mulch and pre sowing seed hardening with KNO3
significantly increased dry matter accumulation and total number of
tillers/plant, ear head length, test weight, grain yield, stover
yield and biological yield also significantly increased with the
modification in surface configuration as ridge and furrow method over flat
sowing, straw and dust mulch and without seed hardening. Modification in
surface configuration as ridge and furrow, plastic mulch and pre sowing seed
hardening with KNO3 enhanced grain yield to the tune of 22.21,
14.40 and 48.82 and 10.50 per cent over flat sowing, straw and dust mulch and
without seed hardening. Ridge and furrow practice of sowing a way of
modification in surface configuration proved more effective and gave
significantly higher water use, water use efficiency, net return 23985, 28189
and 22765 Rs./ha and B: C ratio 2.92, 3.29 and 2.64, respectively. Key words:Pearl millet, Mulch, Moisture, Yield and
