Seed yield increase in Niger crop in to relation to honeybee and other pollinators
Niger (Guizotia abyssinica
Cass) is an important minor oilseed crop of
hilly and tribal regions and it is used for oil
as well as for various other purposes only by
the tribal people. Therefore, a systematic
study was arranged to document about the
increase in the seed yield of niger crop in
relation to honeybees (Aphis mellifera), as a
pollinator in niger crop with paired plot
technique at the Niger Research Station
(NRS) at Navsari Agricultural University
(NAU) and at farmerās field, Vanarasi,
Navsari, Gujarat (India) and also studied its
relation in terms of cost benefit ratio (CB).
The trial was conducted at Niger Research
Station (NRS), Vanarasi for 3 years (2013-
14, 2014-15 and 2015-16) and also at
farmer's field to ascertain the role and
involvement of honey bees (Aphis mellifera)
in swelling the seed yield of niger crop (due
to pollination) and its effect on income due
to increase in the niger seed yield.
Significant differences were observed for
number of capitula/plant, number of
seeds/capitula, 1000 seed weight and seed
yield in both the location for the consecutive
3 years. However, the seed yield and gross
returns were considerably higher in first
location of T1 Natural plot/ open pollinated
with beehive (Aphis mellifera) in all the
3 years data with the maximum seed yield
with the gross return was obtained in this
treatment
Assessment of heavy metal contents of green leafy vegetables
Vegetables are rich sources of vitamins, minerals, and fibers, and have beneficial antioxidative effects. Ingestion of vegetables containing heavy metals is one of the main routes through which these elements enter the human body. Slowly released into the body, however, heavy metals can cause an array of diseases. In this study we investigated the concentrations of copper, chromium, zinc, and lead in the most frequently consumed vegetables including Pimpinella anisum, Spinacia oleracea, Amaranthus viridis, Coriandrum sativum, and Trigonella foenum graecum in various sites in Raipur city, India. Atomic absorption spectrophotometry was used to estimate the levels of these metals in vegetables. The mean concentration for each heavy metal in the samples was calculated and compared with the permissible levels set by the Food and Agriculture Organization and World Health Organization. The intake of heavy metals in the human diet was also calculated to estimate the risk to human health. Our findings indicated the presence of heavy metals in vegetables in the order of Cr > Zn > Cu > Pb. Based on these findings, we conclude that the vegetables grown in this region are a health hazard for human consumption
