Experiment Background
|
Aerobic rice involves sowing dry seed into a prepared seed bed. In india direct seeded aerobic rice production systems are rapidly replacing conventional rice production systems due to various advantages. In india, transplanting is the common method of establishing rice crop. However, this method is not much profitable due to several reasons such as, requirement of huge labour force for raising nurseries, uprooting, transporting of seedling, require large quantity of water to carry out the operation, non availability of labour in time, drudgery to farm worker, high production cost etc. Transplanting alone costs about 15 % of total rice production cost and enhances crop duration 7-10 days. Land preparation for transplanted rice consume large quantity of water i.e., about 20-40 % of total water required by rice crops. So direct seeded rice offers certain advantages to overcome these problems.
Weed infestation at early stages of crop growth is severe in case of aerobic rice. The use of herbicides offers selective and economics control of weeds right from the beginning, giving the crop and advantage of good start and competitive superiority. Keeping all these points in view, the present studies are under taken. |
