Abstract: The decline
in productivity has been attributed to factors, such as decrease in soil
organic matter content, water holding capacity, loss of physical properties,
and number and activity of soil flora and fauna. The plantation sector is
constrained by the unstable prices of commodities and increase in the cost of
production. Under such a situation, a re-orientation of strategies is
required to develop production systems that are agriculturally sustainable,
economically viable and environmentally sound. The maintenance and
conservation of soil fertility is an integral component of agricultural
sustainability, which can be achieved through appropriate management of
organic resources available in the ecosystem in plenty. Recycling of vast
resources of crop residues containing appreciable quantity of nutrients,
produced by plantation crops, offer new avenues for nutrient management in
plantation crops and cropping systems. Key words: Coconut,

Abstract: Herbal treatment is the natural form of healing or
alternative therapy, where herbs or plants are used in the form of extract,
pills, syrup to cure diseases of human or it is the use of plants (herbs) to
treat disease and enhance wellbeing. Herbal treatment is used to treat a
range of disorders including anxiety, depression, high blood pressure,
hormonal imbalance, migraines, skin problems and other disorders. Herbal
medicine has its origins in ancient cultures including those of the
Egyptians, Americans, Indians and Chinese. At present, thousand of plant
metabolites are being successfully used for the treatment of variety of
disorders. The World Health Organization estimated that 80% of people
worldwide rely on herbal medicines for some part of their primary health
care. Increased side effects, lack of curative treatment for several chronic
diseases, high cost of new drugs, microbial resistance and emerging, diseases
are some reasons for renewed public interest in plant based medicines.Some of the plants which are used in the
treatment of mental disorders are sage, ginkgo, cowhage,
valeriana, kava, hops, ginseng, sarpagandha,
these plants and their chemical constituents are very helpful in protecting
the human against central nervous system (CNS) disorders. Keywords: CNS

Abstract: The present paper mainly deals with the effect of aqueous
extract of Parthenium hysterophorus
L. (Asteraceae) on pollen sterility of Vicia faba L.
About 50 g of stem, leaf inflorescence and whole plant parts were grinded
separately to get the mother solution which was further diluted to different
concentrations by adding required quantity of double distilled water.Seeds of Vicia faba L. were treated with different concentrations
viz. 10%, 25%, 50%, 75% and 100% of the extract and also with double
distilled water for the control for four hours at room temperature. The
treated and control seeds were sown in the experimental plots duringwinter season of 2011 to raise
M1 generation with three replicates (each replicate consisted of
100 seeds). Pollen sterility was determined by staining the pollen grains
with 2% aceto-carmine and mounting in 50% glycerine. The pollen sterility of the treated plants
considerably varied (17.50±0.17 to 70.30±0.21) from the controlplants
(03.40±0.16).The ANOVA test confirmed that the extracts of Parthenium parts significantly induced pollen
sterility. It was interesting to note that the inflorescence extract was
highly effective with gradual increasing doses of the extract. Further the
gradation of the effectiveness of Parthenium
plantpart extracts for inducing pollen sterility wasnoted as inflorescence>whole plant>Leaf
>stem. Key words:

Abstract: Kalmegh is one of the important
ingredients in various ayurvedic preparations used
for fever and liver disease, which are commonly used by ayurvedic
physicians. Kalmegh was recommended in “Charak Samhita” in 175 BC for
treatments of jaundice along with other plants in multi plant preparation. Kalmegh is widely used in Indian traditional system of
medicine against different ailments. It is reported that this plant possesses
astringent, anodyne, tonic and alexipharmic properties which are useful in
curing dysentery, cholera, diabetes, influenza, bronchitis, piles, hepatomegaly, skin disorder, fever and worm. The major
bitter constituent in kalmegh is due to the
presence of diterpene lactone
called andrographolide. Looking at the utility and
importance of Andrographis paniculata, an overview is conducted considering some
useful aspects like, Therapeutic uses, genetic
study, spacing, nutrition and harvesting studies to initiate systematic
cultivation of medicinal plants in order to conserve biodiversity and protect
endangered species. Keywords: Andrographolide,

Abstract: In the present investigation, during initial stages (30 and
60 DAS) of crop growth, hydro-priming (0.21), bio-priming (0.33 and 0.24) and
combination of all priming methods (0.27) and at later stage (90 DAS) only
combination of all priming methods (0.27) recorded significantly higher root:shoot ratio as compared to
farmers’ practice. In the present study, priming treatments did not show any
impact on root length at initial stages due to receipt of well distributed
rainfall. In contrast, at 60 DAS combination of all priming methods recorded
significantly higher root dry weight (12.69 g plant-1) and increased
to the tune of 9.8 per cent over farmers’ practice (unprimed seeds) (11.69 g
plant-1). Interaction effect of root:shoot ratio of sorghum indicated that. at 30 DAS, highest root: shoot ratio was recorded in osmopriming (0.54) and biopriming
(0.43) in sole cropping system. At 60 DAS, in sole cropping, hydropriming (0.27) and combination of all priming
methods (0.27) was beneficial. In intercropping, biopriming
(0.27) and combination of all priming methods (0.27) was beneficial. At 90
DAS, in sole cropping, combination of all priming methods (0.30) was
advantageous as compared to rest of the treatment combinations. Key words: Seed

Abstract: In the study it was revealed that, 74.55 per cent of farmers
have used above recommended seed rate (15 kg ha-1). Majority of
the farmers (69.09 %) have followed below recommended spacing (45 cm x 30
cm). The survey data on the usage of fertilizer indicated that, majority of
the farmers have used above recommended dose of N, P and K and only 29.09 per
cent of farmers have used farmyard manure. The quantity of manures applied
indicated that 76.36 per cent of farmers have used < 7.5 t ha-1
and the quantity of manures applied appears to be less than the recommended
dose (7.5 t ha-1). Majority of the farmers (46.36 %) have
harvested lower yield (20 to 40 q ha-1) than the potential yield
of maize in the study area. The major reasons attributed to the low yields
are: erratic and scanty rainfall, lack of proper soil moisture conservation
practices, lack of suitable management techniques to combat moisture stress,
lack of good seed availability, scarcity of labour
and lack of information on new method of cultivation. Due to these reasons
the majority of the farmers (83.64 %) were experienced yield loss to the
extent of 51-75 %. Key words: Maize,

Abstract: Experimental material for study was consisted of 38 early
and mid-season genotypes including four checks (AP-3, VRP-6, PC-531 and
VRP-7).The experiment was conducted in Randomized
Complete Block Design with three replications. Each treatment consisted of
five rows spaced 30cm with plant to plant spacing of 10 cm and replicated
thrice. Each entries were grown in the plot size of3 m x 1.5 m. Observations
were recorded on sixteen character viz. days to 50 percent flowering
(days), nodes per plant, internodal length (cm),
nodes to first flower appearance, primary branches per plant, plant height
(cm), pods per plant, pod length (cm), pod width(cm, seeds per pod, shelling
per cent (%), 100 seed weight (g), T. S.S (oBrix),
pod per cluster, pod weight (g), and pod yield per plant (g). The analysis of
variance for design of experiment indicated highly significant differences
among the genotypes for all the traits. Based on mean performance only one
genotype NDVP-424 among early group and seven genotypes viz. NDVP-517
followed by NDVP-521, NDVP-522, NDVP-503, NDVP-516, NDVP-512 and NDVP-502
among mid-season group were found as significant and most promising genotypes
for pod yield per plant along with some other traits. The estimates of
phenotypic coefficients of variation (PCV) were higher than genotypic
coefficient of variation (GCV) for all the traits. High magnitudes of
variability were observed in case of pods per cluster (28.99%), plant height
(26.03%), pods per plant (25.08), primary branches per plant (22.70%), pod
yield per plant (21.83%), pod weight (21.67%).While, TSS, width of pod, 100
seed weight, shelling per cent and seed per pod exhibited low variability.
High heritability coupled with high genetic advance in per cent of mean were estimated for plant height, pods per plant, pod
yield per plant, pod weight, nodes per plant, nodes to first flower appearance,
primary branches per plant, days to 50 per cent flowering, internodal length, length of pod, 100 seed weight and TSS

Abstract: This study was conducted during summer season for estimation
of good combiners on the basis of fruit qualities against high temperature. A
breeding program was developed between nine parents by using half-diallel mating design in tomato and produced 36 F1
hybrids. Among the parents Riogrande, Suncherry, Superbug and H-24 exhibited good general
combining ability (GCA) and high performance for fruit quality characters viz.,
pericarp thickness, number of locules
per fruit, total soluble solids, lycopene content, self life of tomato fruits, ascorbic acid, and titrable acidity against high temperature. Out of 36
crosses the cross combinations Punjab Chhuhara x Suncherry, Punjab Chhuharax Pusa Sadabahar, Superbug x Pusa Sadabahar, Pusa Sadabahar x IIHR-2201 and Suncherry x Superbug were high specific combining ability
(SCA) estimates for high TSS, titrable acidity,
ascorbic acid, lycopene and shelf life of tomato
fruits in high temperature. Highly significant parents and crosses indicated
to both additive and non–additive gene action for both general and specific
combining ability. Hence these combiners could be effectively utilized in
tomato breeding program for developing high fruit quality of
resistant/tolerant tomato varieties against high temperature and can be
freely cultivated in summer season. Keywords: S.

Abstract:Seed borne disease of green gram like anthracnose caused by C.
truncatum has been reported from all regions of
India in mild to severe form. Attempts were made during post cropping season
to observe the role of infected seeds and crop debris in the perpetuation of
the pathogen. Information with respect to the mode of pathogen survival that
forms an important link and primary source in the infection process as well
as survival from one season to another is meager.In
present studies survival of the pathogen and subsequent germination of
infectious propagules is important in life cycle of
pathogen and subsequent infection chain. The survival studies of C. truncatum in terms of conidial viability under
different storage condition revealed that storing of host debris under
refrigerated condition (4-50c) was favorable to retain more
maximum viability up to 360 days. While incubation of disease plant material
under tree shades (22-250c) the survival ability of the fungus was
up to 255 days. It was observed that the conidial viability under glass house
condition was up to 105 days and under field condition (30-350c)
it was up to 90 days and their potential to act as primary source of inoculum lasts only during cultivation season under field

Abstract: The incorporation of an easily identifiable morphological
marker (naked eye polymorphism [NEP]) could be used to determine genetic
purity. The morphological leaf marker selected for present studies are obcordifoliate, ovalshape,
small, sesamum and gigas
leaf shape, while single leaflet was present only in unifoliate
leaf variant. All such types of leaf are not present in cultivated pigeonpea and can be observed soon after planting
(approx. 6 wk). A genetic inheritance study is essential for transferring
these traits in productive pigeonpea background.
Inheritance studies of leaf traits i.e different
leaf shapes and number of leaflet was studied with seven populations
(parents, F1, their reciprocal, F2, test and back
cross) of ten and two crosses with respective traits. Data analysis of
segregating populations (F2s, test and back crosses) was carried
out with the help of chi-square test. Inheritance studies showed that, all
traits (naked eye polymorphic markers) under studies were governed by single
recessive gene. Present studies reveled that, all these naked eye polymorphic
markers can be incorporated in desirable genotypes because of their
distinctness and can be easily transferred in the desirable genetic back
ground as they are governed by single gene. Key words:

Abstract: Masur (Lens Esculentum)
belonging to family leguminoseae, is also a good
source of dietary protein for consumption by man and animals. Seeds are
roasted and eaten, unripe pods are used as vegetable. Dried husks, stocks and
broken grains is used as cattle feed. Lentil helps
in reducing blood cholesterol, reduces risk of heart failure, prevents
constipation and other digestive disorders, Gram is also an important food
crop of this family. It also helps in stabilizing blood sugar levels, reduces
fat. The Rhizobium a nitrogen fixing
bacteria is the essential feature of leguminous plants. Increased cultivation
of legumes is essential for the regeneration of nutrient-deficient soils and
providing needed nutrients to humans and animals. The present study was aimed
to isolate the beneficial nitrogen fixing Rhizobium
from root nodules of Masur (Lens Esculentum),Lentil and Gram plant. Total of 210 samples of soil
were collected and Screening of 210 isolates by different bio-chemical
methods and efficiency assessment was carried out and Out of which155
isolates of Rhizobium were finally
screened on the basis of biochemical test. Finally 17 isolates were selected
on the basis of efficiency assessment. The Rhizobium
isolates were rod shaped, gram negative, acid and mucous producing. They
were found to be temperature and pH sensitive, with optimum values of 29.4
and 7.0°C, respectively. It utilizes glucose, sucrose and starch as sole
carbon source. The Acetylene reduction activity of the organism was seen
highest in Gram nodules ofMunger District in
comparison to other District.The organism was
present in all areas. This study confirms the presence of Rhizobia
in leguminous fodder in the area. Keywords: Acetylene

Abstract: A Study was conducted during the period from July 2013 to
January 2014 at Fruit Research Station (FRS) Sangareddy,
Medak district, Telangana
to find out the effect of varieties and fertilizer levels on growth and fruit
yield of guava cultivars under meadow system planting. The experiment
consists of two varieties and five fertilizer doses. A total of 10 treatments
were replicated four times in two factorial Randomized
Block Design. Lalit recorded maximum plant
height in meters (1.14) (1.17) (1.21) at 60, 90 days after fertilizer
application (DAF) and at the time of harvest, stem girth in centimeters
(10.30) (10.74) (11.10) at 60, 90 DAF and at the time of harvest, plant
spread in meters at east-west (0.99) (1.08) at 60 and 90 DAF and north-south
direction (1.02) (1.11) (1.17) at 60, 90 DAF and at the time of harvest,total number of flowers per shoot (2.48), number
of fruits per plant (19.15), average fruit weight (177.25 g), and fruit
volume (160.90 cm3). Allahabad Safeda
recorded maximum fruit set (82.38 %) and minimum number of days taken for
harvesting from flowering (118.10).In the present study the different
fertilizer levels were 65:30:30, 100:45:45, 135:60:60, 170:70:70 and
205:90:90 g per plant. Increasing the fertilizer level from 65:30:30 to135:60:60results
in increase ofthe number of fruits per plant,
maximum average fruit weight, fruit girth, fruit volume, fruit yield. But
further increase in fertilizer doses decreased the above characters in meadow
system of planting of guava. Among the interactions Lalit
with 135:60:60 g NPK per plant recorded maximum stem girth (12.08 cm.) at 90
days and at harvest (12.54 cm.). Allahabad Safeda
with 135:60:60 g of NPK fertilizer level showed minimum number of days
(10.44) taken for flowering from first split of fertilizer application and
minimum number of days (116.21) taken for harvesting from flowering.
Application of 135:60:60 g NPK per plant for two years old guava plant in two
split doses were found to be optimum in increasing better growth, fruit yield
and quality of guava cultivars under meadow system of planting in Telangana. Key words: Allahabad

Abstract: Anthracnose remains an important biotic factor constraining
the efficient production of mungbean in tropical
and subtropical regions of the world. Mungbean
anthracnose caused by Colletotrichum truncatum (Schw.) Andrus
and Moore is one of the most important seed borne disease of mungbean (Vigna radiata L. Wilczek) in the
world. The disease causes symptoms to appear on stems, petioles, leaves and
pods. It causes considerable damage by reducing seed quality and yield. The
pathogen can survive in seeds for up to five years, and is also known to
overwinter in crop debris. Seed infection is the primary means by which the
pathogen spreads. Therefore, the production and the use of certified seeds is
one control measure that is effective in dealing with the disease. Correct
and accurate identification of its causal organism is essential for tailoring
appropriate control or management techniques for this impediment. Fungicidal
seed treatment and foliar application as well as cultural and biological
methods are very important for mungbean anthracnose
management. Further information on biology and survival of C. truncatum is needed to devise more effective
management strategies. In this review attention were given to the biology and
management options, with an emphasis on the future research priorities. Key words: Anthracnose,

Abstract:Genetic variability studies provide basic information
regarding the genetic properties of the population based on which breeding
methods are formulated for further improvement of the crop. The estimates of
heritability, coefficients of variability and genetic advance computed for 12
yield contributing traits. Genetic parameters for yield and its correspondent
characters in rice were estimated from a trial with four CMS lines, fifteen
testers, three checks and sixty crosses evaluated for twelve characters
related to yield. In general, the magnitude of phenotypic coefficient of
variation (PCV) was higher than the corresponding genotypic coefficient of
variation (GCV) for all the traits, indicating that the apparent variation is
not only due to genotypes but, also due to the influence of environment.
Therefore, caution has to be exercised in making selection for these
characters on the basis of phenotype alone as environmental variation is
unpredictable in nature. High estimates of heritability and genetic advance
in broad sense and narrow sense were recorded for all characters. High
heritability coupled with high genetic advance in percent of mean was
observed for all the traits, indicating predominance of additive gene action
for these characters. Hence, simple selection based on phenotypic performance
of these characters would be more effective. The estimates of additive
variance () was found higher than the dominance variance () for all
characters. The degree of dominance was greater than the unity for the
characters spikelets per panicle, spikelet
fertility, 1000-grain weight, biological yield per plant, L/B ratio and grain
yield per plant, indicating the presence of over dominance gene action. Key Words:

Abstract:Inhibitory effect of excess Ni was observed in Zea mays (L.) plant. The leaves
of plants receiving excess amount of Ni showed chlorosis
of apical foliage and yellow brown coloration. Damaged tissues were also
observed in both older and younger leaves, however
these symptoms appeared in younger leaves first. Minimum depression in shoot
was noted as 1.0mMdose of nickel, however 2.5 folds depression were observed
at 4.0mMdose. At 1.0, 2.0 and 4.0mM supply of nickel carotenoids
content dropped respectably. A noticeable decrease of a, b and total
chlorophyll has been observed in maize with increasing concentration of
nickel. Higher values of protein content were obtained respectively at 2.0
and 4.0mM Ni dose. No significant effects were observed at different doses of
Ni in the activity of catalase and peroxidase except at a dose of 2.0mM Ni. No effect was
observed at 1.0mM conc. of Ni in the activity of total amylase, but this
showed negative effect at 2.0mM and 4.0mM dose of nickel. Key Words:
