Abstract: Alternaria blight (Alternaria brassicae)
causes severe damage to Indian mustard in the country. Affected leaf samples
were collected from ten different places for the isolation and purification
of pathogen to study the cultural and pathogenic variations.The
fungal colonies of A. brassicae varied in
their cultural behaviour ranging from fluffy to
compressed, with wavy, smooth to rough margins. Colonies colour
varied from black, brown, light brown to dark brown and growth varied from
slow, medium to fast on different culture media. Variation in zonation and sporulation on
different medium were also observed in the isolates under study. Among the
media in general, the fastest growth of each fungal isolates were recorded on
PDA as compare to others; while slowest growth was recorded on Czapek-dox agar medium. On mean basis the maximum mycelia
growth (83.77 mm) and dry weight of fungal (354.34 mg) was recorded on PDA
while, minimum mycelial growth as well as dry
weight (79.54 mm and 322.5 mg) was recorded on Czapek-dox
agar medium respectively. Among the isolates, isolate Ab3 of Uttrakhand was noted fast growing with maximum mycelial growth of 90.0 mm and dry weight of 449.0 mg
followed by isolate Ab7 of Haryana (89.13 mm and 440.6 mg) and Ab6 of West
Bengal (88.37 mm and 426.0 mg) but, all were at par statistically and grouped
together.Similar pattern was recorded on other
medium also. On the basis of growth and dry weight of fungus the isolates
were grouped into three categories. Category one have isolates Ab3, Ab6 and
Ab7, category two have Ab1, Ab5 and Ab8, while category three have Ab2, Ab4,
Ab9 and Ab10. All the isolates were found pathogenic in nature on different Brassica spp. Maximum percent disease intensity
(PDI) of each isolate was recorded on B. juncea
(56.70) followed by B. campestris var.
yellow sarson (51.69) and was B. nigra (49.34), while it was recorded minimum in B.
carinata (17.21). On the basis of pathogenic
variability, the isolates were grouped same as in case of cultural variation.
Hence, it can be suspected that the isolates obtained from different
agro-climatic region may be grouped into three categories, which indicates
the prevalence of three different strains/races in the different part of
country under study. Key words: Alternaria

Abstract:
Biodiversity of pollinators on fennel cv. HF-143 (Foeniculum
vulgare Miller), was studied in Hisar, Haryana, India. Twenty five insect species
belonging to fifteen families of five orders were recorded from fennel cv.
HF-143 flowers, in which, seven belong to order Lepidoptera, nine to
Hymenoptera, five to Diptera, three to Coleoptera and one to Odonata.
Among the insect pollinators, Apis florea F., A. cerana indica F., A. mellifera
L. and A. dorsata F. were the most frequent
pollinators. Among different bee species, the maximum mean population
observed in case of Apis florea (9.23 bees/m2/5 min) followed by A.
mellifera (3.62 bees/m2/5 min) and A.
dorsata (3.21 bees/m2/5 min),
whereas, the least abundance was observed in case of A. cerana indica,
i.e., 1.82 bees/m2/5 min. Among different Apis
species, A. florea spent maximum time
(4.49 sec/umbelet) followed by A. mellifera (1.71 sec/umbelet)
and A.cerana (1.21 sec/umbelet).
The least time per umbelet was recorded in case of A.
dorsata, i.e., 1.11 seconds. Among different
bees, A. dorsata visited maximum number of umbelets (20.27 umbelets/min)
followed by A. mellifera (14.71 umbelets/min) and A. cerana
(11.99 umbelets/min). Apis
florea visited least number of umbellets i.e., 7.34 umbelets/min.
The yield/plant (19.40 g), yield/m2 (181.32 g), test weight (12.32
g) and per cent germination (81.20) were significantly higher in case of open
pollinated flowers as compared to those where insect pollinators were
excluded (14.72 g, 140.04 g, 8.52 g and 58.80%, respectively,). In case of
open pollination, the per cent increase in yield/plant, yield/m2,
test weight and per cent germination over without insect pollination was
31.79, 29.48, 44.60 and 38.10%, respectively. Hence, insect pollinators were
essential to get good returns in this seed crop. Key words: Abundance,

Abstract: Fifty genotypes of lablab bean were used to study the
genetic diversity. Observations were recorded for twelve morphological and
yield attributing characters and the data were analyzed using Mahalanobis’s D2 statistics. All the
genotypes were classified into five distinct clusters, grouping together the
less divergent genotypes. The genotypes exhibited sufficient variability to
select genotypes for further breeding programmes. The largest cluster
comprising of 34 genotypes formed by Cluster I while Cluster II and Cluster
III had 6 genotypes each, followed by Cluster IV and Cluster V had three and
one genotype, respectively. The maximum inter cluster distance was observed
between Cluster IV and Cluster V, followed by those between Cluster II and
Cluster IV. The parents for hybridization could be selected on the basis of
their inter-cluster distance for isolating useful recombinants in the next

Abstract: Creation of the protected areas is of paramount importance
at all levels i.e sate, national and international
for formulating the biodiversity conservation strategies. These areas act as
an abode for the species which are otherwise, endangered or at the brink of
extinction, allowing such species to prosper in their natural ecosystems. The
purpose of protected areas is to preserve the flora and fauna in their
natural habitats and acts as a benchmark to study their interactions with the
natural world. In the study site habitat characteristics, diversity of trees
and shrubs, delineation of forest tree communities and the regeneration
pattern of tree species was assessed. 64 sites were sampled between 2100-
3496 m above msl and a total of 23 forest
communities were recorded from the study area out of which 16 were tree
communities and 07 were shrub communities. Abies
pindrow and Quercus
semecarpifolia communities was the most widely
distributed followed by Abies pindrow-Taxus baccata subsp.
wallichiana mixed and Prunus cornuta
communities. Aesculus indica-Prunus
cornuta mixed community had maximum
density of trees (670.00 Ind ha-1),
while Abies pindrow
community recorded the maximum total basal area (319.08 m2 ha-1).
Minimum density and basal area was recorded for Betual
utilis community (135.00 Ind
ha-1; 5.60 m2 ha-1). Of the total forest
tree communities, 07 communities (i.e. Abies
pindrow, Acer acuminatum,
Aesculus indica, Betula utilis, Picea smithiana, Prunus cornuta and Quercus semecarpifolia)
showed highest regeneration of dominant species and 02 communities (i.e. Juglans regia and
Juglans regia-Picea
smithiana mixed) of co-dominant species
indicating the possibility of partial replacement of the dominant species by
the co-dominant species in the future. Long term monitoring of these tree
communities for their conservation management is suggested. Key words: Concentration

Abstract: A cashew, well known as climate smart crop, a study was
undertaken to evaluate the performance of the organically grown crop for
consistent and stabilized yield under varied weather conditions of plain
track of Karnataka. The study revealed that during September to December
where flushing (vegetative growth) is active, highest average temperature
recorded was 29.26°C, 27.91°C, and 29.21°C respectively in September to
December of 2012, 2013 and 2014. Similarly, Highest average temperature
recorded was 32.57° C, 33.44°C, and 34.90°C respectively in January to May of
2012, 2013 and 2014 which coincides with flowering and fruiting time. There
was an increase in temperature from year to year. The data revealed that in
the first year (i.e. end of 2013) of study, there was no significant yield
differences observed between organic and inorganic practices (20.76 &
20.20 Kg per plant respectively in organic & inorganic system) whereas,
increasing yield in organic system was 21.45 Kg (4290 Kg per ha) of cashew
nuts per plant compared to 20.52 Kg (4104Kg per ha) in inorganic system at
the end of April 2014. There was a significant increase in yield to the tune
of 5.00 per cent recorded with organic system at the end of second year of
the study i.e. April 2014. Organic system significantly improved the soil
quality and the sustainability index of the soil was maximum with organic
practices (1.59) compared to inorganic one (0.88). The study supports the benefit
of adopting organic system in enhancing and stabilizing production through
increased productivity. Further, in spite of the varied weather (Temperature
and rainfall) in 2012, 2013 and 2014, cashew could give consistent and
stabilized yield under plain track of Karnataka, indicating its suitability

Abstract: An experiment was conducted on 10 farmer’s fields of three
villages such as Bhadoni, Patlawada
and Mandalkhan of Shajapur
District, Madhya Pradesh to study the sowing technique (i.e
raised bed furrow system) of soybean to mitigate the climate change scenario
and boost up the productivity of crop.In the
prevalent tradition system (Flat method of sowing), seeds are placed under
the soil which requires more energy to break soil crust at the time of
germination hence causes poor germination. Under the mechanization sowing
through raised bed furrow System, the seed is placed on the bed as a paired
row and make a one deep furrow after each bed. By using this technique, row
to row distance 30 cm and furrow to furrow distance 60 cm were maintained.
These furrows served as a moisture retainer at the time of moisture stress
condition during low rainfall and saved crops by moving moisture due to
surface tension in upwards portion. During heavy rains the one end, slopping
downward, was opened to drain water from the field. Soil moisture content was
estimated at various depths viz. 10, 20, 30, 40 and 50cm, at 15, 30, 45 and
60 days after sowing. The soil moisture was recorded 22% under raised bed
furrow system at the depth of 30-40 cm on flowering stage as compared to
prevalent traditional method of sowing was 16% only. Likewise it was also
observed that the other parameters i.e. No of pods and yield were
significantly higher than the farmers techniques, hence the soybean
productivity increased 26.9%. So it may be proved that this method may be
better sowing techniques to augment the soybean production in the State as
well as in India. Key words:

Abstract:The seed lot of
chickpea was treated with polymer (4 ml/kg seed) second lot treated with polymer
(6 ml/kg seed), third seed lot treated with the Neem
oil @ 8 ml/kg seed, fourth seed lottreated with
Pepper fruit powder @10 gm/kg seed and fifth seed lot is control. Afterthe treatment, the seed samples were stored in
different types of packaging materials viz. polythene bags (non vacuum
packaging), polythene bag (vacuum packaging), cloth bags, jute bag, jute +
polythene bag (non vacuum packaging ) and kept at room temperature for a
period 2, 4 and 6monthswith 10 % seed moisture content. At the end of the
experiment after 6 months of storage period under ambient condition,
treatment of polymer (6 ml/kg seed) was proved to be superior as it enhanced
the seedling characters i.e. germination percentage, root length,
shoot length, seedling length, and seedling vigour
index, fresh weight and dry weight of seedling, seed viability, seed vigour and germination rate. Inthe
packaging materials, seedling parameters were also found superior in plastic
bags (vacuum packaging) as compared to plastic bags (non vacuum packaging
),Jute bag, cloth bag ,Jute + plastic bag Germination and vigour
percentage decreased with the period of storage. Key words:

Abstract: The experimental site falls under subtropical sub humid zone
in Indo-gangatic plains having alluvial calcareous
soil. The composite soil sample was taken from different depths (up to 60 cm)
and places with the help of soil augur and analysed
for its physical and chemical characteristics. The scientific name of this
variety is IFT-10364. Its height is 85-95 cm, matures in 135 days and average
yield is 45 q ha-1. Transplanting of rice seedling in experimental
field was done manually by using 25 days old seedlings. Two to three seedling
hill-1 were transplanted at about 3 cm depth at a spacing of 20 ×
10 cm. All the growth and yield attributes increased significantly with
increase in nitrogen level up to 80 kg N ha-1 though the highest
value was recorded with 120 kg N ha-1. The highest grain yield of
27.62 q ha-1 was recorded with120 kg N ha-1 which was
at par with 80 kg N ha-1 and significantlybetter
over control and 40 kg N ha-1 showing an increase of 0.38 , 3.88
and 7.25 q ha-1 over 80, 40, 0 kg N ha-1, respectively.
Application of phosphorus resulted increase in all the growth and yield
attributes significantly with increase in dose of phosphorus up to 40 kg P2O5
ha-1 only. The maximum grain yield of 28.78 q ha-1 was
recorded with application of 40 kg P2O5 showing an
increase of23.46 and47.58 per cent over, 20 kg P2O5 ha-1

Abstract: Drought has been the single largest factor limiting the rice
yield in rainfed areas. Developing rice cultivars
with drought tolerance is the most efficient way to solve this problem. Because
of physiological and genetic complexity, drought tolerance is probably the
most difficult trait in rice to improve through conventional breeding.
Application of molecular techniques along with conventional approach is the
only option for improvement of drought tolerance. During the present
investigation 27 introgression lines developed in the genetic background of
IR-64 at IRRI, Philippines, along with five checks IR-64, Sarjoo-52, Nagina 22, Narendra 97 and Swarna were evaluated under drought and irrigated
conditions. For identification and validation of QTLs associated with
drought, the introgression lines were scan with microsatellite markers and phenotypicobservation were recorded on seedling vigor,
leaf rolling, days to 50% flowering, plant height, panicles bearing tillers
per plant, Spikelets per panicle, grains per
panicle, spikelet fertility (%), test weight (g), biological yield (g), grain
yield (g) and harvest index (%).Experimental results revealed that analysis
of variance for the design of experiment indicated highly significant
differences among treatments for all the characters. Four SSR primers were
used for screening purpose but out these, three primers exhibited
polymorphism and validated its association with drought QTLs. Key words:

Abstract: A study was conducted to develop a new mutants of stevia with a higher content of Steviol
Glycosides is the primary aim of plant breeders concerned with the
improvement and utilization of the source of natural sweeteners. Manipulation
of ploidy is a valuable tool and has been used in
plant breeding programme to improve agronomic
yield. Different stevia mutants were developed
using Colchicine (0.25%, 0.50%, 0.75%, 1.0%, 1.50%,
and 2.5 %) treated plants were treated for their DNA content to ascertain the
change in ploidy. The mutant plants each were
tested for better growth, yield and content of active components. Ploidy level was identified by Flow cytometry
analysis. The steviol glycoside content in the
leaves was determined by HPLC. Analysis of variance revealed highly
significant differences among the plants. However,plants
showed increased plant height, leaf size, thickness, chlorophyll content,
reduced internode length and two and half times the
percentage of stevioside compared to control. Thus
induction of tetraploidy in Stevia
confirmed the effectiveness of colchicines as a polyploidizing agentcratingnew
variants with higher biomass and steviol
