I think Drip irrigation can adopt in direct seeded rice crop. There are several literatures in the research area.

Rao et al., 2017 observed greatest plant height and root length with SRI under drip irrigation at 20 cm spacing. Yield and yield contributing parameters were also

significantly higher with this treatment as compared with conventional practice. Please see the links:

Thank you

@ shweta, yes people are using drip irrigation in direct seeded rice crop. Please have a look some of the attached publication.

There is literature in the web for drip irrigation in direct seeded rice.

Ya madam, we can you both surface drip and sub-surface drip in DSR and other field crops also. You can find literatures in Agricultural Water Management journal

There are two different methods of direct seeding in rice. One is 'broadcasting ' and the other is raw seeding. Drip irrigation cannot be adopted if the crop is broadcast sown. However, drip irrigation may be adopted in a raw seeded crop with difficulty but may not be cost effective.

Drip irrigation can adopt in direct seeding of rice crop

Several research have been performed in the issue, most prominently by Rao et al. (2017), Effects of drip irrigation system for enhancing rice (Oryza sativa L.) yield under system of rice intensification management, Applied ecology and environmental research, 15(4):487-495, DOI: 10.15666/aeer/1504_487495

Yes,drip irrigation can be successful in DSR particularly under heavy texture clay soil.Only limitation is cost involved on lateral and its upkeep.

thanks for all giving me ans.

I want to know what will be the actual spacing and irrigation requirement and other agronomic practices.

Yes, drip irrigation is possible in direct seeded rice.Drip allows cultivating rice like other crops through regular land preparation, and direct seeding and using fertilizers according to the crop stages and supplying them directly to the crop root zone. This way, require lesser fertilizers, and subsequently reduce fertilizer cost. Continuous irrigation from natural resources such as fresh rain water sustain the expansion of rice plant in paddy fields, this is often an important a part of cereal agriculture for lowland rice with in the flood plains of tropical region. Continuous irrigation by artificial water of land is the major challenge for upland rice in North India, where precipitation is low and dependence on nutrients dissolved in soil moisture. Due to water scarcity, Rice cultivation is becoming unaffordably and unpredictable in many areas across the world. The use of Drip irrigation in rice combined with fertigation has a benefit for rice production. At one side the water consumption is reduced to a great extent when we use drip and at the same time under non-stress situation paddy respond with higher yields. In order to meet the demand of rice production and conserve ground water resources for future we have to go for precision water management which is achieved by Micro irrigation system. Drip irrigation shows impressive results, doubling water productivity, and getting more grain for every drop.

Drip irrigation cannot be adopted in direct-seeded rice cultivation because it is not practically feasible and economically viable as rice is cultivated in large extents and large quantities of seed (100-75 kg/ha) is sown in direct-seeded rice. In addition drip irrigation system may get blocked due to getting in soil particles into the system during heavy rains.
