Abstract The
field study was conducted during 2020 and 2021 on farmer’s field of Hora Bangar of
Kanpur Nagar district. The operational area is situated in the catchments of
river Ganga. The soil of pilot project was
sandy loam, having low fertility status. The field trial was undertaken in
the partnership of farmers. Two varieties i.e. Azad Ageta
Khira (newly developed variety) and Kalayanpur Hara were tested. The newly developed
cultivar Azad Ageta Khira
gave maximum fruits yield by 258.50 q/ha over Kalyanpur
Hara (213.60 q/ha). The highest gross return of Rs. 180950/ha, net return of
Rs. 140980/ha and BCR of 1:4.53 were found under test cultivar of Azad Ageta Khira. Therefore,
under changing climate cv. Azad Ageta Khira was found most suitable genotype for riverine tract of Uttar Pradesh. Keywords: Azad Ageta Khira, Changing climate,

Abstract Intensive industrial developments in last
few decades have increased the concentration of a large number of chemicals
in the biosphere, the habitat of all living organisms, including man.
Anthropogenic activities resulting from modern methods of agriculture,
urbanization, industrialization have involved the increased use of various
types of chemical pollutants and toxicants especially heavy metals, which
ultimately reach into aquatic environments and become responsible for the
degradation of aquatic ecosystem. Among metallic pollutants arsenic is one of
the most relevant environmental global single substance toxicants. It is one
of the few substances known to be carcinogenic to humans through the
consumption of drinking water. Arsenic has been found in nature since
antiquity. Fish can be an excellent source of material for the study of the
heavy metal pollution in water as they are aquatic vertebrate, which can
metabolize, concentrate and bioaccumulate water
pollutants. There are many cytogenetic end points that can be used as an
indication of exposure to genotoxic substances in
aquatic organisms. Induction of Chromosomal aberrations and micronuclei can
act as an important bio-indicator of the presence of arsenic in the water. Keywords: Genotoxicity, Fish, Arsenic,
Chromosome aberrations (CA) and Micronuclei (MN) |

(2022) Possibility of companion

Abstract The
field experiment was laidout during summer season
of 2009-10 and 2010-11 in catchments area of river Ganga.
Site of pilot area was sandy loam, having low plant nutrients status. The
three treatments i.e., colocasia alone, onion alone
and colocasia + onion were tested. In companion cropping
of colocasia and onion, the row ratio was
maintained 9:1. Nine rows of colocasia was planted
first and, thereafter, one row of onion seedling planted, with this system of
planting whole experimental plot were completed. The colocasia
cv. Baruasagar was planted on first
fortnight of February, thereafter, the cv. Kalyanpur
red round of onion transplanted. Both crops harvested full maturity stage.
Alone crop of colocasia gave yield by 242.00 q/ha,
while pure crop of onion yielded 251.00 q/ha. The highest total productivity
of companion cropping of colocasia and onion was
harvested by 267.00 q/ha. The gross return of Rs.
667500.00/ha and net return Rs. 576188.00/ha were computed under companion
cropping of colocasia and onion. The higher LER was
found in companion cropping of colocasia + onion by
1.11, therefore, 11% yield advantage was noted under
companion cropping system of colocasia + onion. Keywords: Catchments
