Aus paddy is a major cereal crop of Bangladesh. The paddy which are sown during the month March-April and harvested in July-August every year is considered to be Aus paddy. There are two types of Aus paddy namely local Aus and high yielding variety (HYV) Aus. From time immemorial Aus paddy which is grown in our country is called local Aus. Generally this type of paddy does not need irrigation and is purely dependent on natural rainfall. It gives a lower yield. HYV Aus is generally transplanted. If weather remains dry, plants sometimes demand irrigation.
Production of Aus:
Bangladesh occupies most lands of the great Bengal plane of the Ganges Delta with affluent alluvial soils. Moreover, it is a riverine area with plentiful water resources with hot and humid monsoon climate. All these factors have made Bangladesh the most significant for paddy cultivation in the world. However, the overall natural climatic / weather and geographic condition of Bangladesh is blissful for growing paddy.
Acreage, production and yield rate of Aus Rice from the year 1998-99 to 2007-2008 are presented in the above table. It reveals that total area under Aus crop shown in the table has been declining gradually. Sharp increase in the area under Boro crop is responsible for decrease in the area under Aus crop. But it is interesting to note that yield rate shows upward trend, it may be due to increasing trend of HYV Aus cultivation.
Statistical Findings about Aus in Bangladesh:
The production cost survey for Aus crop was carried out in September, 2008. In this survey, data on area under Aus paddy, land tenure, leasing, means of land preparation, seed and seedling cost, quantity and cost of fertilizer used, insecticides cost, sowing / plantation, weeding, harvesting, thrashing and other related cost were collected.
Moreover, per acre production cost as well as per kilogram (KG) production cost were computed. It is observed from the above table that the area under Aus crop was 37.08%, 61.08%, and 1.84% for local, HYV, and hybrid respectively. It is to be noted here that area under hybrid Aus is not significant in Bangladesh. In cultivation of Aus crop, Chittagong division covers a large area (29.01%) compared to other divisions. For HYV Aus, Khulna division achieves the highest portion (29.44%). Survey data show that no hybrid Aus are cultivated in Sylhet division.
The above chart reveals that HYV Aus covers large area almost two-third of total area under Aus crop while a little over one-third area is planted by local Aus.
