Physiological and yield responses of five rice varieties to nitrogen fertilizer under farmer’s field in IADA Ketara, Terengganu, Malaysia
Studies have suggested that the need for site-specific fertilizer application to reduce waste of resources as soil nutrients varies across the Malaysian rice fields. The present study was aiming to determine the physiological and yield responses of five rice varieties (MR269, MR297, MR220CL2, MR219,...

Studies have suggested that the need for site-specific fertilizer application to reduce waste of resources as soil nutrients varies across the Malaysian rice fields. The present study was aiming to determine the physiological and yield responses of five rice varieties (MR269, MR297, MR220CL2, MR219, and UPUTRA) treated with three nitrogen (N) rates under farmer’s field condition. The experiment design was a split-plot randomized complete block design, in which N rates, i.e. low (76 kg N ha-1), farmers’ practice (109 kg N ha-1) and high (142 kg N ha-1), were the main plot while rice varieties were the sub-plot. In general, harvestable panicle yield including the grain (at 14% moisture content) of all varieties was between 5.4 and 7.4 t ha-1 under all N treatments. Among all varieties, MR220CL2 recorded significantly higher yield, irrespective of N treatments.
