Abstract
A field experiment was conducted to study the influence of composted rice
straw with different rates of urea on the yield of Sakha 101 rice variety (Oryza sativa
L.) and yield attributes, agronomic efficiency and. organic matter.
The obtained data showed that the highest yield was found when 2 ton of
composted rice straw plus 51.75 kg N.fed-' was applied. The combination of nitrogen
plus compost gave higher yield than either nitrogen or composted rice straw alone.
The highest value of number of panicle.hill" observed when 2 ton composted rice
straw + 51.75 kg N.fed-' added. Results showed that, no significant difference in
panicle length and filled grain percentage among all treatments. Higher 1000-grain
weigh~ was found in plots received no fertilizers.
Integration of composted rice straw plus nitrogen improved agronomic efficiency but increasing the amount of nitrogen applied decreased the agronomic efficiency. Data showed that, all treatments, which treated with composted rice straw,
increased organic matter compared to the other treatments
