ABSTRACT
Field investigations were conducted at research farm, JNKVV Jabalpur during kharif season of 2010 and 2011 to study to the production efficiency and monetary advantage in rice by adopting suitable planting geometry, varieties and depth of planting. The experiment comprises on 18 treatment combinations consisted of three planting geometry (20 cm × 20 cm, 25 cm × 25 cm and 30 cm × 30 cm) as main plot treatment and three varieties (MR-219, WGL-32100 and PS-3) as sub plot treatments and two depths of planting shallow (2.5cm) and normal (5.0 cm) as sub-sub plot treatments were tested in split-split plot design with three replications. The result revealed that the 30 cm × 30 cm planting geometry had superiority in various parameters viz; root depth/hill, fresh weight of roots/hill, dry weight of roots/hill root volume/hill (cc) were significantly influenced by plant geometry. Rice variety MR-219 with shallow depth of planting (2.5 cm) was markedly superior in growth parameters viz., number of roots/hill, root depth/hill, fresh weight of roots/hill, dry weight of roots/hill root volume/hill (cc) under SRI method.
