(2) Agricultural Development: With limited land, fast growing labor force, slow rate of labor
and lack of serious policies for enough investment in agriculture by the govts.
the food crises rose in some UDCs. Moreover, in LDCs, the heavy emphasis is laid
on industrialization for which there is the need for foreign exchange. Hence,
they did not have enough foreign exchange for the food imports. Moreover, the
natural calamities like droughts etc. often created large troubles for LDCs.
Therefore, the govts. of LDCs should think of increasing productivity in
agricultural sector. This could be possible by inventing miracle seeds for wheat
and rice. The miracle seeds were first used in Mexico and are known as Mexican
seeds. The use of these seeds resulted in increasing agri. production much
higher than traditional varieties.
(3) Double and Multiple Cropping: The invention of new seeds had the effect of increasing the cropic intensity.
Earlier in many LDCs the system of double cropping was uncommon. The arrival of
new dwarf varieties of seeds will open up the possibility of double and multiple
cropping in large scale. This rise in cropic intensity will increase per acre
yield substantially. Thus farm income will begin to rise in the areas covered by
HYV (High Yielding Veriety) projects. Farmers attitude towards risk will change when their production
will go above MCN.
(4) Increase in Use of
Fertilizers: The other factor which greatly increased the food production and per acre
yield is a rise in the use of fertilizers. There exists a positive relationship
between fertilizers use and crop response. It has been observed that nitrogen
fertilizers along with HYV of wheat and rice have increased the production three
times more as compared with the traditional variety. Thus through the effect of
fertilizers on yields and increasing multiple cropic the fertilizers play a
vital role in promoting GR in LDCs. To increase the use of fertilizers the
subsidies have been given to farmers in so many UDCs. But it has been also
observed that there exists an inverse relationship between the use of
fertilizers and their prices. Despite this problem with GR, fertilizers have
played an important role, particularly in raising agri. surplus.
(5) Increase in Irrigational
Facilities: The other important element which spread GR is the availability of irrigation
facilities. The use of fertilizers and other complementary inputs will not give
the desirable result if the regular and timely water is not supplied. The case
of Punjab in Pakistan where the yield of wheat rose most dramatically because of
good irrigation facilities. The average yield from irrigated lands is 30 to 100
% higher than un-irrigated lands. Therefore, in the presence of better
irrigational facilities GR can play an important role.
