Effect of foliage clipping on grain yield of basmati rice (Oryza sativa)

摘要

Since lodging is considered as one of the main bottlenecks in realizing potential yield of traditionally tall basmati rice, a field experiment was conducted during 2001, in Punjab, India, to study the effect of extent and stage of foliage clipping on the grain yield of basmati rice. The results revealed that the maximum grain yield (29.0 q/ha) was registered in clipping of one-third foliage from the top at 30 days after transplanting followed by clipping at the time of transplanting (25.3 q/ha). Similarly, foliage clipping of one-third from the top produced higher grain yield than clipping one-half foliage from top. The foliage clipping only once produced higher grain yield than clipping twice at 30 and 60 days after transplanting..
