Methods of Planting Rice 1 This is one of the rice production training modules produced by the International Rice Research Institute. Rice is life for thousands of millions of people. But imprecedented drought conditions in 2002-03 resulted in sharp decline in production, area and yield of rice in India. Therefore they do not take any initiative for soil-conservation and improvement. Seeds are sown broadcast by hand. Cultivation (tillage) is a practice that has been introduced to Australia from Europe by our farming pioneers. Yield also reached at the highest level of 2,077 kg/hectare.

DISADVANTAGES OF CULTIVATION Cultivation has the potential to destroy soil structure and make soils more prone to other forms of degradation, such as erosion. Some of the disadvantages are time, commitment, initial expenses, and frustrations of growing things. It is interesting to note that the rate of increase in production is much higher than the rate of increase in area under rice cultivation. Rice is the most important food crop of India covering about one-fourth of the total cropped area and providing food to about half of the Indian population.
