Rooting Behaviour of Aerobic Rice under Integrated Package of Agrotechniques
C.M. Sunil and B.C. Shankaralingappa

Abstract:
Aerobic rice is a new system of rice cultivation under limited water condition. Rice having a shallow root system is not a desired character for water stress condition. Therefore, a deep root system is needed for acquiring water and nutrition from the relatively wet deep soil layer to obtain a stable yield under aerobic conditions. In this context a pot experiment was conducted during Kharif, 2011 and 2012 at Zonal Agricultural Research Station, GKVK, Bengaluru to investigate the effect of integrated package of agrotechniques on rooting behaviour and yield of aerobic rice. The observations pertaining to root growth were recorded at panicle initiation stage and at maturity. The root growth parameters viz. root length, root number, root volume, root dry weight and shoot dry weight were significantly higher with the application of RDF+FYM+Biofertilizers+FeSO4+IWM practices (T8) as compared to all other treatments. The grain yield per plant and straw yield per plant also followed the similar trend.
