Rice (Oryza sativa L.) is a main staple for human consumption all over the world. There is ever increasing demand for rice with increasing population and that too it has to be produced on the same stretch of land or less. Secondly, in many of the rice-rice cropping areas the second crop of rice of late is becoming doubtful due to reduced possibility of season-long availability of water for the succeeding crop due to climate change impacts. Energy is the other critical input. |
