Root Proliferation and Grain Yield of Wheat and Triticale under Irrigated Conditions

Root distribution pattern of four wheat (Sonalika, Kalyansona, UP 301 and Hira) and one triticale (Branca 90) varieties under irrigated conditions, down to a depth of 60 cm and la ateral distance of 24 cm from the plant, were worked out by using ³²P plant injection technique. When considered on the basis of per cent roots concentrated in deeper layers (36–60 cm depth), different varieties form a sequence in the order Sonalikco > Branco > 90 > Kalyansona > UP 301 > Hira. Similarly, when considered on the basis of per cent roots concentrated in a lateral distance of 8–24 cm the sequence in the order is: Sonalika > Bronco 90 > Hira > UP 301 > Kalyansona. These sequences are, by and large, similar to those reported earlier (Sharma et al. 1974) under unirrigated conditions, which show that the three irrigations did not exhibit any marked influence on the root distribution pattern over that obtained under unirrigated conditions. However, both wheat and triticale yielded mire under irrigated condition.
