A study on saving water using drip irrigation technologies in paddy and enhancing yield

Abstract

We know that water is essential for growing rice and it requires standing–water for proper growth and successful cultivation. The practice probably started when under prevailing conditions the farmers has tweaked rice seedling to grow in accumulated water. The first records of rice cultivation projects it as a dry seeded crop grown in ends of high land and forests cleared for shifting cultivation. It’s in China that the process of puddling soil and transplanting seedlings began in low-lying area and river valleys. As transplanting gives a head–start for rice seedlings in their fight with weeds, this method took an easy route of acceptance in other parts of the world especially in South Asia where originally rice is grown under dry land conditions. But the current scenario is entirely looking for water saving technologies and the aim has been shifted from 'crop productivity' to 'irrigation/water efficiency'. This can be by micro- irrigation that can improve the water use efficiency,
