Abstract: Sclerotinia sclerotiorum (Lib.) de Bary
is soil borne, necrotropic fungal pathogen causes
stem rot disease in all Brassica species
depending upon the stage of plant growth and environmental conditions in
Haryana state. The experiment was carried out to find out the relationship
between growth stages and Sclerotinia rot infection
in different Brassica species under
artificial inoculated conditions at research area of Oilseeds Section,
Department of Genetics and Plant Breeding, Chaudhary
Charan Singh Haryana Agricultural University, Hisar during rabi 2013-14.
Significant variations among different Brassica
species were observed for stem rot disease severity as well as days to stem
breaking, when inoculated at different stages of plant growth. Maximum
disease severity ranging between 80.0-93.3 per cent was recorded in Brassica rapa var. Brown
sarson, B. rapa
var. Yellow sarson and B. rapa var. Toria genotypes,
when 50 days old plants were inoculated as compared to 60 and 70 days old.
B. juncea, B. nigra
and B. alba genotypes showed maximum disease severity ranging between
40.0- 73.3 per cent, when 60 days old plants were inoculated as compared to
50 and 70 days old. While, in B. napus and B.
carinata genotypes, when 70 days old plants
were inoculated, showed maximum disease severity ranging between 76.7-81.7
per cent as compared to 50 and 60 days old plants. Early stem breaking
ranging from 20.7- 30.0 days after inoculation was observed in B. juncea, B. nigra and B.
alba respectively, when 60 days old plants were inoculated. A delay of 10
days in stem inoculation resulted in delay of 7-9 days to stem breaking. It
has been concluded that different Brassica
species have different congenial growth stages for artificial inoculation
under field conditions. Key words:

Abstract:In gladiolus, based on Mahalanobis’s
D2 analysis, the genetic divergence studies were conducted in
twenty genotypes and they were grouped into five divergent clusters. Among
all the characters, the most important character contributing to divergence
was diameter of corm followed by weight of the spike and weight of corm.
Among the grouped five clusters, cluster I was the largest group comprising
of 13 genotypes followed by cluster IV of 4 genotypes and all other cluster
comprises of single genotype in each cluster. Intra cluster distance was
highest in cluster IV (93.99) followed by cluster I (58.44).The inter cluster
D2values were maximum (244.37) between cluster I and IV. The
minimum distance observed between cluster II and III (52.92). The genotypes Arka Kesar from cluster II, Tilakfrom cluster III and ArkaAmar,Arka Gold,Arka Naveen, Sagar from cluster IV,

Abstract:Eighteen kilometer stretch of Yamuna River studied by measuring
various physicochemical parameters of water quality during pre-monsoon and
post-monsoon 2014. River Yamuna, during its flow through Sirmour
district in Himachal Pradesh receives domestic and industrial effluents from
different villages and Ponta-sahib industrial hub situated on its banks.
Depending upon the location of point sources of industrial effluent
discharges, eight sampling stations were selected for collecting the water
samples. Maximum pH (7.95±0.03), EC (304.32±0.16) ěmhos/cm,
TDS (88.91±1.08) mgL-1, BOD (15.24±0.01)
mgL-1, COD (29.79±0.04) mgL-1, Fe (0.220±0.0) mgL-1
and Zn (2.760±0.0) mgL-1 was observed in
pre-monsoon, whereas maximum, turbidity (27.17±0.02) NTU was recorded in
post-monsoon season. There was significant increase in all parameters from
the upstream of Pontasahib municipal and industrial
town to the downstream Satiwala (station 1 to 8).
All the parameters were within the permissible limits of drinking water
standards except BOD and COD. The BOD values at all the monitoring stations,
were higher compared to 5 mgL-1.
The maximum value of BOD (15.24±0.01) mgL-1
and COD (29.79±0.04) mgL-1 was observed
at a distance of 18 km at Satiwala village (S8)
during pre-monsoon season. Based on the results of BOD and COD stretch of the
river can be categorized as class of stream ‘D’ for which the designated best
uses are propagation of wild life fisheries, irrigation, industrial cooling
and controlled waste water disposal. It can be ascribed to the discharge of
untreated domestic waste, industrial effluents at the upstream of all the
monitoring stations and urban runoff from industrial hub. Keywords: Yamuna

Abstract: The field experiment was conducted under South Gujarat
conditions to evaluate the effect of spraying of water soluble fertilizers on
growth, yield and economics of okra production. The experiment comprised of
seven treatments with spraying of water soluble fertilizers and each were applied thrice at 30, 45 and 60 DAS. Among the
different treatments tested, three sprays of banana pseudostem
enriched sap @ 1 % or mixed fertilizer (19:19:19 @ 0.5%) resulted in
achieving higher plant height, number of fruits per plant, yield per plant,
dry fruit yield, dry plant yield and commercial green fruit yield in okra.
From the economics point of view, for securing maximum return, an application
of enriched sap (T6) was found superior with the highest BCR of
3.6:1. Both these treatments (T1 and T6) were found
economical, profitable and proved highly remunerative for okra production. Key words:Foliar Spray, Water soluble fertilizers, BCR and Commercial fruit

Abstract: The present study was aimed to evaluate the economic
feasibility of growing organic tomatoes under farmer’s conditions in mid hill
conditions of Himachal Pradesh. The budget identifies specific cost
categories and estimates a net return for the production and sale of organic
tomato crop. Therefore, in this study, cost effective methodology for organic
fruit and seed production of tomato was developed. It was observed that
highest cost of production for fruit and seed yield (Rs.1,15,934 and
Rs.1,20,034, respectively) and maximum gross income (Rs.3,90,449.01 and
Rs.2,09,601.67, respectively) were observed in the treatment ’T7'
(Vermicompost + Biofertilizers).
However, maximum net returns for fruit and seed yield (Rs.2,99,384.87 and
Rs.1,17,984.01, respectively) and benefit: cost ratio (3.60:1 and 1.35:1,
respectively) were recorded in treatment ’T9' (Biovita
+ Biofertilizers), whereas lowest cost of
production (Rs.77,934), gross income (Rs.1,79,348.67), net returns
(Rs.1,01,414.67) and benefit: cost ratio (1.30:1) for fruit yield were
observed in the treatment ’T10' (Control).Therefore, treatment ’T9'
from economic point of view and treatment ’T7' for retention of
soil fertility year after year and getting high fruit and seed yield, can be
recommended for commercial cultivation of tomato in hilly regions of the
country. Key

Abstract: The present study was conducted using 19 genotypes of wheatunder sodic soil
conditions during the crop season of 2012-13. These genotypes were evaluated
for ten characters. Grain yield per plant showed highly significant positive
correlation with biological yield per plant and significant positive
correlation with number of effective tillers per plant followed by number of
grains per spike, number of spikelets per spike and
harvest index at phenotypic level. The estimates of genotypic correlation
coefficient were generally similar in sign or nature but higher in magnitude
than the corresponding phenotypic correlation coefficient. At phenotypic and
genotypic levels, grain yield per plant had strong and positive association
with biological yield per plant followed by number of effective tillers per
plant, number of grains per spike, number of spikelets
per spike and harvest index. Based on the results, it is reasonable to assume
that high yield of wheat in these genotypes could be obtained by selecting
breeding materials with number of effective tillers per plant, number of
grains per spike, number of spikelets per spike and
biological yield per plant. Key words:Wheat, Genotypic and phenotypic correlation coefficients |

Abstract: Ten genotypes and forty five F1sof bread wheat were evaluated in randomized block
design (RBD) with three replications for yield and yield contributing traits
during rabi 2013-2014, to find out
the genetic variability, heritability and genetic advance percent of mean.
Analysis of variance revealed significant differences among treatments for all the trait. This indicated the presence of significance
variability (both genotypic and environmental) in the present set of material
which allowed for conducting further genetic analysis. PCV values were higher
than GCV values for all the traits which reflect the influence of environment
on the expression of traits. Highest PCV and GCV observed for peduncle length
8.58 and 8.41 respectively. All the characters except tillers/ plant,
biological yield/plant, and economical yield/ plant in the present
investigation indicated high heritability. High heritability indicates the
scope of genetic improvement of these characters through selection. All the
traits under study showed low genetic advance. Most of the character
exhibited high heritability along with low GAM indicated the presence of
non-additive gene action. Keywords: Wheat,

Abstract: An experiment was carried out during kharif
2012 to evaluate genetic diversity among 100 differentially adopted
cultivated rice genotypes including 4 standard check varieties (Sarjoo-52,
NDR 359, PB- 1 and CSR 30). Analysis of variance showed highly significant
differences due to treatments for all the characters. Observations were
recorded fourteen distinct agronomic traits.The
non-hierarchical Euclidean cluster analysis grouped one hundred four
genotypes into eleven distinct clusters. This indicated existence of high
degree of genetic diversity in the genotypes evaluated. The eleven clusters
formed in divergence analysis contained genotypes of heterogeneous origin
thereby indicating no parallelism between genetic and geographic diversity.
Therefore, crosses between the member of cluster separated by high inter
cluster distance are likely to throw desirable segregants.
In this context cluster IX had very high inter cluster distance from clusters
IV, II, X, XI and III. Thus, crosses between promising lines belonging to
cluster pairs having high inter-cluster distance may be attempted for
isolating transgressive segregants. Key words:

Abstract: Rainfall determines the potential of any region in terms of
crops to be grown, farming system to be adopted, the nature and the sequence
of farming operations to be done. On an average 9.62 % of cultivated area of Dediapada taluka (Dist.
Narmada) is under irrigation, remaining 90.38 % area is under rainfed agriculture (Annual Progress report: 2011-12,
KVK, NAU, Dediapada). The amount of rainfall
received by the region is sufficient for rainfed
farming in Kharif season. Morris and Zandstra (1979) criteria and Raman (1974) criteria of
onset and withdrawal of effective monsoon have been used for estimating the
most suited SMW (Standard Metrological Week) for commencement of sowing
operation, requirement of supplementary irrigation during rainfed
crop and withdrawal of Monsoon. For maximum one-day rainfall analysis,
observed rainfall values have been obtained from Weibull’s
formula while the expected rainfall values have been estimated by using
frequency factors for the different probability distributions i. e. Normal, Log-Normal, Pearson type III, Log-Pearson
type III and Gumbel distribution. 27th SMW receives sufficient rainfall for
commencement of sowing operations. There are 75 % and 60 % probability
to get minimum 10 mm for continuous 77 days (27th
to 36th SMW) and minimum 20
mm rainfall for continuous 9 SMW (27th
to 35th) respectively. Supplementary irrigation
is not required during the period. Log-Pearson type –III distribution is best
fitted among all the five distributions as it gives lowest chi-square value i. e. 22.83. Maximum one-day rainfall for different
returns periods from Log-Pearson type III i. e. 5,
10, 15, 20, 25, 50 and 100 years are respectively 189, 245, 280, 307, 329,

Abstract: The present investigation was carried out in the two
consecutive years i.e. 2011-12 and 2012-13 at Main Experiment Station,
Department of Horticulture, NDUA&T, Faizabad, (U.P.). The experiment was conducted in RBD replicated
four times with twelve treatments. The treatments involved in the study were
12 in numbers i.e. FYM in six different doses (0, 05,10,15,20 and 25 t/ha)
and nitrogen through Urea in six different doses (0, 25, 50, 75,100 and 125
kg/ha). Among the FYM doses, FYM (25 t/ha) had more pronounced effect on
plant height and number of primary branches. The maximum plant height
(75.77cm) and number of primary branches per plant (12.90) were noted with
application of FYM @ 25 t/ha followed by application of Urea @ 125 kg/ha
(74.21cm and 7.2 respectively) and minimum in control (58.15 cm and 7.2 respectively).
Whereas, FYM (20 t/ha) increased number of secondary branches per plant
(30.41) followed by application of Urea @ 100kg/ha (29.02). The highest fresh
and dry biomass at flowering bud initiation stage (41.91 kg/ha and 9.25
kg/ha) were observed with application of FYM @ 20 t/ha. Keywords:

Abstract: The experiment was done to assess the effects of different
concentrations i.e. Lethal Concentration (LC5), Lethal
Concentration (LC50) and Lethal Concentration (LC95) of
Potassium Permanganate on hydrological parameters of water.Analytical
grade Potassium Permanganate (KMnO4) of
Merck India Ltd. was used for the experiment. The toxicity bioassay of
Potassium Permanganate (PP) was conducted separately for 2hr, 3hr and 4hr of
exposure to the fingerlings of Clarias gariepinus in controlled laboratory conditions. The
mortality percentage of the test organisms were recorded after every one hour
of exposure. Two types of bioassay i.e.Range
Finding Bioassay & Lethal Toxicity Bioassay was conducted to get the 100%
mortality of the test fish.Lethal Concentrations
(LC) of this toxicant at which the test organisms died (LC5 to LC95)
was calculated by the method of EPA Probit Analysis
Program (Version 1.5). Impacts of Potassium Permanganate on different
hydrological parameters like Temperature, pH, Conductivity and Dissolved
oxygen of test water were recorded after every 1hr of interval. It was
observed that the pH, DO of water increased but conductivity of water
decreased after application of KMnO4 and
Temperature of test water was not varied significantly (P>0.05) during the
experiment. It was also concluded that it should not be recommended as an
ideal Piscicide and its applications as
disinfectant, therapeutants and prophylactic are
strongly encouraged. Keywords:

Abstract: Enzyme dynamics and soil properties in soil amended with
levels of urea, DAP and FYM in aerobic and flooded ecosystems was conducted
in a red sandy loam soil in eastern dry zone of Karnataka. The nutrient
status of the study site was low in organic carbon (3.4 g kg-1),
nitrogen (168 kg ha-1), phosphorus (13.84 kg ha-1) and
potassium (174 kg ha-1). The experimental design used wasRCBD with 7 treatments viz., 150 % RDF, 100 % RDF+FYM
@ 10 t ha-1, 50 % RDF+5 t ha-1FYM, urea at
100 % N equivalent, DAP at 100 % N equivalent, FYM at 100 % N equivalent and
absolute control. The test crop was rice hybrid, KRH-2. The results revealed
that addition of 100 % RDF+FYM@ 10 t ha-1 recorded a significant
increase in enzyme activities (urease, phosphatase and dehydrogenase)
throughout the crop growth period over control in both aerobic and flooded
ecosystems. Between ecosystems enzyme activities were higher in aerobic
system than flooded system. All the enzymes showed significant and positive
correlation with organic carbon, available nitrogen, phosphorus and
potassium. Key

Abstract:On the basis of overall lowest mean percentage of leaf
infestation 10.70% of L. trifolii recorded
in the plots treated with NSKE (5%) followed by tobacco extract (5%) 11.77%
and NSKE (2%) 22.09%. However, treatments, NSKE (5%), tobacco extract (5%)
and NSKE (2%) were observed significantly less 2.11, 2.62 and 4.52 flies/10
cm twig B.tabaci population, respectively as
compared to rest of the treatments. Treatments, NSKE (5%), tobacco extract
(5%) and NSKE (2%) were observed significantly less 1.60, 2.07 and 3.21 A.
devastans populations per six leaves,
respectively and NSKE (5%) and tobacco extract (5%) were also observed
significantly less 2.84 and 3.67 per six leaves A. gossypii
population, respectively. The treatments, NSKE (5%) and tobacco extract (5%)
were observed significantly less larval population of H. armigera 1.21 and 1.57 larvae/plant, respectively.
The average less percentage of fruit damaged (6.71 % and 10.97 %) and less
percentage yield loss (20.38 and 23.25 %) were recorded in NSKE (5%) and
tobacco extract (5%) treatments and considered the most effective treatments
against H. armigera. On the basis of above
results, NSKE (5%) and tobacco extract (5%) were most effective treatments
against L. trifolii, B. tabaci, A. devastans,
A. gossypii and H. armigera.
NSKE (2%) (16.99 %) and tobacco extract (2%) (17.84%) were found moderately
effective than other treatments in respect of less percentage of damaged
fruits. Treatment, NSKE (5%) was recorded significantly highest fruit yield
147.50 q/ha. Followed by tobacco extract (5%) (135.57 q/ha.) than rest of the treatments. On the basis of overall
performance and economics of these different phyto
extracts, NSKE (5%) and tobacco extract (5%) were most effective treatments
against the major insect pests of tomato. NSKE (5%) & tobacco extract
(5%) gave highest net return (Rs. 47915 & 42700/ ha.) with C: B ratio of
1: 3.70 and 1:3.50, respectively. Keywords: Tomato, Bio-efficiency, Phyto-extracts,

Abstract:An investigation was carried out with 126 genotypes of forage
sorghum at instructional farm of Rajasthan College of Agriculture, Udaipur
during summer 2013 to asses association of fodder yield components and their
direct and indirect effects on green fodder yield per plant conducted. It was
observed that the green fodder yield I cut was significant and positively
correlated with dry fodder yield I cut both at genotypic (0.89) and
phenotypic (0.66) level. The phenotypic correlation of green fodder yield I
cut was also significant with dry fodder yield per day (0.66), leaf: stem
ratio (0.28) and leaf breadth (0.26) in positive direction and with protein
percent (-0.26) and total soluble solids (-0.24) in negative direction. The
green fodder yield II cut was significant and positively correlated with dry
fodder yield per day II cut at both genotypic (0.99) and phenotypic (0.99)
level. The phenotypic correlation of green fodder yield II cut was positively
correlated with leaf: stem ratio (0.30) and significant negatively correlated
with early vigor (-0.20). Correlation between these characters was also in
same direction. Path coefficients for green fodder yield at I and II cut were
computed using genotypic correlation between characters recorded independently
and having significant difference between genotypes. The 14.15 % variability
of green fodder yield I cut and 8.86 % variability of green fodder yield at
II cut was explained by these 4 and 9 characters
respectively. Maximum direct effect was leaf stem ratio followed by total
soluble solids, leaf breadth and protein per cent towards green fodder yield
I cut and leaf: stem ratio, regeneration ability, stem diameter, number of
leaves per plant and total soluble solids towards green fodder yield II cut.
Hence these characters may be considered as selection indices in sorghum
breeding programme. Key

Abstract: In the present study the role of catalase
activity and chlorophyll content were examined at 60 and 90 days in salinity
as well as control condition in leaves of rice genotypes. The levels of salt
stress with EC=12 dS m-1, were used in a
randomized complete block design with three replications under net house conditions.Salinity treatment was started from 21 days to
maturity and maintained at EC=12 dS m-1
at pH=5.Tolerant genotypes were Pokkali and Nonabokra followed by NUD-3, FL-478, CSR-13, NUD-2, CSR-30
and CSR-90-IR-2 showed reduction in total chlorophyll content and increased catalase activity as compared to the control one. The
susceptible genotypes IR-28, IR-29, Swarna sub-1,
NDR-359, Sarjoo52, and IR-64 highly reduced total chlorophyll content and
less increased in catalase activity and ultimately
lower grain yield per plant as compared to the control plants. The responses
observed in tolerant genotypes to salinity stress were higher in catalase activity and less chlorophyll degradation than
sensitive genotypes under salt stress. Keywords:
