Growth of rice affected by different treatment applied in SRI method

Field investigations were conducted at research farm JNKW Jabalpur (Madhya Pradesh) during kh arif season of 2010–11 and 2011–12 to study to the growth, development and production efficiency in rice by adopting suitable planting geometry, varieties and planting depth. The study revealed that the 30 cm x 30 cm planting geometry had superiority in parameters viz., plant height, and functional leaves/hill the 30 cm * 30 cm planting geometry had superiority in various parameters were significantly in plant geometry. Rice variety MR-219 with shallow depth of planting (2.5 cm) recorded better growth parameters viz., plant height, Number of tillers/m² and functional leaves/hill were markedly superior in growth parameters. Grain and straw yields were superior with the MR-219 variety and 25 cm * 25 cm planting geometry with shallow depth of planting.

System of rice intensification method plants obtain higher plant growth and development for obtaining higher rice production with suitable wider spacing and improved MR-219 variety and shallow depth.

The cumulative effects of superior growth and yield attributes were finally reflected interms of higher grain yield were significantly superior in MR-219 with suitable 25 cm x 25 cm planting geometry and shallow depth.
