Weed Dynamics in Wheat as Affected by Rice and Wheat Establishment Methods
Abstract
Phalaris minor density was highest in wheat after dry seeded rice (DSR). It was 21.8 and 37.6% higher than in wheat after wet seeded rice (WSR) and transplanted rice (TPR), respectively. Chenopodium album density in wheat after DSR was 38.0 and 49.6% higher than in wheat after WSR and TPR, respectively. Polypogon monspeliensis density in wheat after DSR was 67.5 and 75.0%, higher than in wheat after WSR and TPR, respectively. In conventional tillage wheat (CTW), P minor, C. alhum. P monspeliensis and other weeds had 84.8, 77.8, 71.8 and 33.3% higher density than in zero tillage wheat (ZTW). respectively.
