Inbred Varieties and their Characteristics of rice crops

Rice is the principal food of our people and grown in this country from time

immemorial. It contributes for about 92% of the total food grains produced in the

country. Seventy-five percent of required calories and 55% of protein are met from

rice in the average daily diet of the people. Bangladesh is the fourth largest rice

producer in the world. It covers about 77% of agricultural land and engages about

70% of population in rice production activities. Nearly 50% of our employments are

generated in rice sector. The contribution of rice to GDP is 18%. At present, rice

occupies 11.42 million hectares of land and produces about 33.6 million metric ton

(BBS, 2011). Nobanno (new rice harvest) is one of the joyous festivals, which is

largely observed in rural areas. Different kinds of delicious foods are made from rice

in different occasions. Products of the rice plant are used for different purposes, such

as fuel, thatching, industrial starch, animal feed and artwork. It also ensures political

stability and food security for the people.

Rice is grown year-round in Bangladesh as pre-monsoon crop, direct seeded and

transplanted Aus rice from March to June (kharif-1), wet season transplanted aman

rice (kharif-11), from June to November and dry season irrigated Boro (rabi) rice

from November to May.
