1 Gamma Irradiation brings mutation in Seeds this helps.
a. In improving Quality of Seeds
b. makes seeds resistant to several harmful diseases
c. Brings out better yield in Crops.
2. Gamma irradiation of stored foods enhances the self-life.
a. In improving Quality of Seeds
b. makes seeds resistant to several harmful diseases
c. Brings out better yield in Crops.
2. Gamma irradiation of stored foods enhances the self-life.
However this irradiation by Gamma Rays will not make the products radioactive as it will not change the Chemical Element.
3. Radioisotopes can be used:
to study mobility characteristics of fertilizers in soil and uptake of materials in plants.3. Radioisotopes can be used:
Also radio-tracers are helpful to get a clear understanding of flow of micronutrients
PROJECTS AND DEVELOPMENT INDIA Ltd.
Service Years 1967-1996 (centric PSU) with about 400 Gadgets:
Sindhri R & D laboratories and
Hindusthan Fertilizer Corporation Ltd.
Agricultural Wing jointly developed facilities for the above studies both at the levels of laboratory and extended fields.
The facilities included:
A. Spot irradiation Chamber,(Gamma Chamber) containing 2500 Ci Cobalt-60
B. Extended field irradiation facility to plants & crops in an area of 8 acres, known as Gamma-Garden with 1000 Ci cobalt-60 specialized.
C). Radio-Tracer Lab having Glove Boxes, Beta, Gamma Chamber Facilities also are used by Agricultural Wing(PUSA) at Rajendhra Nagar Agricultural College, Bihar:
RESULTS ACHIEVED:
Changes of inferior quality Ground nut seeds to a good quality an of higher yields types.
Quality changes in some Pulses & millets
Increase of Sugar content in Sugar Cane
Suitable plantations identification in various soils.
Economic application of Fertilizers & micronutrients for achieving high agricultural yields.
