Rice is one of the most important cereal crops in Nepal. As per the preliminary estimate of Fiscal
Year 2003/2004. the rice crop is grown in 1.6 million hectare with the production of 4.5 million
metric tonnes and the productivity is 2.9 t/ha .. It contributes nearly 20% to the agricultural gross
domestic product and provides more than 50% of the total calories requirement to the Nepalese
people. The United Nations Organization has also declared 2004. as the "International Year of
Rice ". There are less possibilities of bringing more lands into production. Therefore, we have to
increase the productivity per hectare per day by any means . The promising technologies
generated by agriculture research play the pivotal role. Nepal so far has released and registered
forty-nine (49) rice varieties with full package of practices within the span of thirty seven (37)
years. The modern varieties can express their yield potentiality only when recommended
packages are practiced Quality seeds alone can contribute 15-20% yield. Seed selection can be
done by following the specific gravity principle. Early paddy and Boro (winter) rice can be used
for increasing rice yield by utilizing higher intensity of solar radiation. The system of rice
intensification (SRI) is the other agronomic manipulation which can increase rice yield. However,
we should not forget the environmentally-friendly and sustainability issues while increasing the
productivity and production. Thai is why these days we say "Evergreen Revolution "and not "
Green Revolution "only. It is said "Grow Paddy with Soil Fertility Wheat with Fertilizers "and
also said " Healthy Seedlings are responsible at least for half of the yields ".
