Magnetic Field On Seed Germination And Transplant Growth Of

Tomato (Lycopersicon esculentum Mill) cv. Castlrock seeds
were exposed to different magnetic strengths (0.1, 0.15 and 0.2
Tesla) for periods of 1, 5, 10 and 15 minutes and the treated
seeds were germinated under distilled water or in saline
concentration levels of 2500, 5000 and 7500 ppm. The results
indicated that the magnetic field treatments led to a
significant increase in the germination percentage, reduced the
time needed for germination and improved seed germination under
saline conditions. The best results were found by magnetic seed
treatment with 0.1 Tesla for 15 min. On the contrary, high
salinity concentrations decreased the germination of seeds, as
for the saline concentration of the 2500 ppm activated the seed
germination. In the nursery experiment, applying the optimal
magnetic seed treatment (0.1 T for 15 min) and/or irrigation
with magnetized water gave significant increases in transplant
stem length, stem diameter, leaf area and fresh and dry weight
than those in the control treatment which grew by untreated
seeds and irrigated by ordinary (untreated water) water.

ABSTRACT: Lepidium sativum
Brassicaceae), a popular vegetable producing plant of low
reaches of Kumaun Himalaya, is an annual herb and its leaves are
used as a Traditional Medicines to cure abdominal pains, asthma
and lowering blood pressure. An aqueous Extract derived from the
leaves of the plant, highly food supplement for human,has
previously been screened for various biological activities,
hypotensive, antimicrobial, bronchiodilator, hypoglycemic and
allelopathic. n-Butanol fraction of aqueous-methanolic extract,
a highly flavonoid enriched and antioxidative active against
DPPH and ABTS free radicals, afforded three flavonol glycosides,
quercetin-3-O-β-glucosyl (1 à
2)– glucopyranoside- 7-0- glucopyranoside, kaempferol-3–O– β-
glucosyl (1 à
2)- glucopyranoside – 7 – O – β – glucopyransoide and
isorhamnetin – 3 – O – sophoroside -7 – O – β – D – glucopyransoide . The antioxideant activity of quercetin – 3, 7
– di-O-glycoside was found higher compared to the corresponding
3,7–di-o-glycosides of kaempferol and isorhamnetin.

education and training is very cardinal to any economic
development of a country. Training in general has potential
benefits which accrue to the individual, organization and the
nation in general. To the individual training enhances their
future earning potentials career progression ad employability.
To achieve the above, the paper argues that the individual or
groups will need skills to perform competently. With skill the
individual can determine their own destiny. Because of the
importance of skills to the individual, it is important that
every individual access training to contribute to development.
Currently Nigeria, not everybody is able to access training with
the rise in population growth and economy going down,
governments are unable to offer social amenities. Even schools
and colleges cannot match the rising population and as a result
fewer and fewer people are accessing training. The paper
therefore focused on the contribution of a revitalized technical
and vocational education and training to improve the economic
status of the country and welfare of the people, trigger
entrepreneurship which would eventually lead to job creation.
The paper concludes that to solve the problem of widespread
poverty, unemployment and national food deficit, priority should
be giving to revitalized-technical and vocational education.
