Abstract Autophagy is a very crucial
process in plants and is highly conserved in eukaryotes. Autophagy
involves the recycling of cell component to maintain cell homeostasis but
also help plants to cope up with adverse environmental stimuli. In this
review we have discussed about how autophagy plays
role of cell survival in different stress conditions leading to nutrient
starvation in plants and also how autophagy can
delay apoptosis or programmed cell death in plants. Keywords: Autophagy, Abiotic stress, Apoptosis, Necrosis |

Abstract Hematological
parameters have been recognized as valuable tools for monitoring fish health
induced by any changes in the quality of waters and other related
environmental factors. In present study, assessment of heavy metals
concentration in fresh water Bhaghar Lake (located
at Tahsil-Ramnagar, District- Barabanki,
State-Uttar Pradesh, India) concerning their effects on hematological
parameters in fish Channa punctatus from it were carried out. The water and
sediments of the lake were analyzed for zinc (Zn), copper (Cu), and lead (Pb) concentrations. At the same time, blood parameters of
the exposed fish were also examined for any hematological modifications. The
results revealed that concentrations of the metals differs significantly
(p<0.05) between the lake water and sediments. The concentration (mg/l) of
the metals were in the order of Cu>Zn, whereas Pb
was not detected in any sample. Blood parameters such as blood cell count
(red and white blood cells), hemoglobin, hematocrit,
mean cell hemoglobin concentration, mean cell volume, and mean cell
hemoglobin were noted to be altered from their normal value in fish (p<
0.05). In conclusion this study indicated that Cu and Zn polluted the lake
water and posed their harmful impact on fish health. Further this is the
first report on distribution of heavy metals and proximate composition of
important edible fish from this fresh water lake in India. Keywords: Bhaghar Lake,
Hematological parameters, Channa punctatus, heavy metals |

Abstract Lentil is one of
the major Rabi pulse crop grown in India. it’s a
rich source of protein, minerals and vitamins for human nutrition and straw
is also valued animal feed. Wilt of lentil caused by Fusarium
oxysporum f. sp. lentis
in the most serious disease of lentil crop. Variability among twenty isolates
of Fusarium oxysporum
f. sp. lentis (Fol)
collected from different lentil growing location of Bundelkhand
region in Uttar Pradesh was studied in respect of cultural, morphological
characters and pathogenic variability. Isolates of Fol-2, Fol-6 and Fol-16
recorded the maximum colony diameter 90.0, 90.0 and 88.33 mm respectively.
Isolates Fol-1, 2,
4, 6, 7, 9, 10, 11, 12, 14, 15, 16 and 17 produced abundant sporulation while remaining isolates produce good sporulation. The isolate Fol-2 and Fol-16 recorded the
maximum mycelia dry weight (710.66 and 645.00 mg) respectively and the least
mycelia dry weight (238.00mg) was recorded by isolate Fol-8. All the isolates
showed significant variation in size of microconidia,
macroconidia and septation. Keywords: Fusarium oxysporum f. sp. lentis,
Lentil, cultural, morphological and
pathogenic character |

Abstract Linseed disease incidence survey was conducted in the five
district of Eastern Uttar Pradesh, from 2018-2019 to 2019-2020 for two years.
The five districts with one Tehsil was selected from Jaunpur,
Varanasi, Mirzapur, Chandauli
and Azamgarh. Three villages were selected in each
district with three farmers fields and the data were
recorded separately. Varanasi was severely infected with the maximum average
PDI 51.10% followed by Chandauli 51%, Mirzapur 49.18%, Azamgarh
49.06% and the minimum average PDI (45.92%) was recorded in Jaunpur in the year 2018-19. Similarly in year 2019-2020 Azamgarh was found to be most affected district with the
average PDI of 51.11% followed by Jaunpur 48.96 %,Varanasi 47.88%, Mirzapur
46.62% and the minimum average PDI
(45.86%) was recorded in Chandauli in year 2019-20.
Among the surveyed district the maximum average PDI in the year 2018-19 was
found in Varanasi (51.10 %) and minimum average PDI was recorded in Jaunpur (45.92%). In year 2019-20 the maximum average PDI
was found
in Azamgarh (51.11%) and minimum average PDI
(45.86%) was recorded in Chandauli district. Keywords: Linseed, Wilt,
Survey, Fusarium oxysporum f.sp. lini. |

Abstract The adaptive trial
on intercropping was laidout on farmer field in
winter season of 2002-2003 under National Agricultural Technology Project, Mainpuri. The main objective was to harvest higher yields
of garlic and colocasia in intercropping and obtain
the better net return from salt affected soils. The yield of alone garlic was
harvested by 105.00 q/ha. Similarly, pure colocasia
gave yield by 253.00 q/ha. The intercropped garlic and colocasia produced 78.00 q/ha and 165.00 q/ha,
respectively. The highest net returns of Rs. 643406/ha was found in
intercropping of garlic and colocasia. The BCR
recorded by 1:5.00 under intercropping of garlic and colocasia.
Therefore, newly developed intercropping system proved superior over pure
cropping of garlic and colocasia. Keywords: Colocasia, Garlic, Intercropping, LER, Salt affected soils |

Abstract Integrated pest management technology is a
science based decision making process that identifies and reduced hazards from both
pest and pest management related strategies. Worldwide losses due to these pest are estimated to be about 34 % to attainable
tomato yield under current production practices. The adoption of IPM
technology in tomato using African marigold as a trap crop, root dipping of
seedling in Imidacloprid,
soil application of neem cake spraying bio-pesticide like HaNPV has been
found higher by about 46 %, cost of
cultivation has been less by 21 % and
the net returns have been higher by
119 %. IPM was formlized in 1970 and continue to be exchange to meet the challenges of keeping
pest and pest damages to acceptable levels, while minimizing collateral
damages. The finding presents the rate of adoption of IPM technology has increased over the
period because of increased yield, gross income in net return in IPM adopters
as compared to IPM Non-Adopters. secondly the profit
of IPM adopters in terms of net returns was more as compared to IPM
non-adopter, Therefore the finding of the study enforced to the adoption of
IPM technology. Keywords: Integrated Pest Management, Trap crop, Pest and pest
damage, Tomato crop, IPM adopter and IPM Non-adopter |
