Abstract

Growing BERSEEM CLOVER (Trifolium alexandrinum) prior to RICE can be a good strategy for reduction of chemical fertilizer consumption and increasing the sustainability of the RICE cropping systems. For this purpose, a field experiment was conducted by using a split-plot based on randomized complete block design (RCBD) with three replications, at the RICE Research Station of Tonekabon, Iran in 2014-2015. Growing BERSEEM CLOVER and use of FALLOW (control), were assigned to main plots, and amount of PHOSPHORUS FERTILIZER (without P and 25, 50, 75 and 100 kg.ha-1 P) to the sub-plots. At crop maturity, seed YIELD, YIELD components and phosphorus content of seeds were evaluated. The results showed that seed YIELD of RICE (7566.3 kg.ha-1) after clover was significantly higher than after FALLOW (6465.1 kg.ha-1) (p<0.05). Growing clover before RICE significantly increased panicle number per m2 and number of filled seeds per panicle, but it did not effect thousand seed weight, significantly. Increasing application of phosphorus, from 0 to 75 kg.ha-1, increased seed YIELD significantly by (30.49 %), but higher phosphorus application (100 kg.ha-1) did not seed YIELD significantly. While, panicle number per m2 (20.5 %), filled seed number per panicle (12.93 %), biological YIELD (22.05 %), seed P content (14.95 %) and seed P uptake (49.2 %) were increased significantly with the application of P fertilizer as compared that of not using of PHOSPHORUS FERTILIZER. Based on the result of this experiment, the highest paddy YIELD could be obtained when RICE planted after clover and use of 75 kg.ha-1 of PHOSPHORUS FERTILIZER.
