Comparative study on ratooning potential of standard rice varieties of PNG.

Abstract

The comparative ratooning potential of 4 standard varieties of PNG was studied under lowland field conditions. The crop performance was measured for yield and yield components, of both the main and ratoon crop. Senis was the highest yielding and the yield of rest of the varieties was statistically at par with each other, in the main crop. On contrary to this Wantok and Tambu were the highest yielding varieties under ratoon crop, while Niupela and Senis yielded significantly lower. The yield and its components of the varieties behaved similarly. Wantok and Tambu seem to be good for ratooning.
