Impact of different crop geometries and depths of planting on growth and yield of rice

An experiment was conducted during the kharif seasons of 2010–11 and 2011–12 at Krishi Nagar farm, Department of Agronomy, JNKVV Jabalpur to study the different crop geometries and depths of planting on growth and yield of rice in system of rice intensification. The results revealed that 30 cm × 30 cm planting geometry had superiority in various parameters, viz, growth and yield, and were significantly influenced by plant geometry and depth of planting. Rice variety MR-219 with shallow depth of planting (2.5 cm) was markedly superior in growth parameters, viz., number of tillers/m² at harvest. Almost all the yield parameters, viz, test weight, harvest index, grain and straw yields, were superior with the MR-219 variety and shallow depth of planting.
