ABSTRACT

The field experiment on the effect of genotypes and methods of establishment on root traits, growth and yield of aerobic rice was conducted during 2004 and 2005.  The study consisted of two methods of establishment viz aerobic and puddled and five genotypes viz. BI-43, Rasi, BI-27,  KRH-2 and H-9 replicated four times.  The results revealed that BI-43 under aerobic condition recorded significantly higher grain yield (40.2 q ha-1) as compared to BI-27, KRH-2 and H-9 under puddle conditions.  Significantly higher root volume (67.00 cc), root weight (9.1 g), root length (27.9 cm) and root number (155.2) were recorded under aerobic condition compared to puddling. From the study it is concluded that genotype BI-43 under aerobic situation is the better practice to increase yield under rainfed upland situations.
