Abstarct: In order the effect of nitroxin ,vermicompost and supperphosphate triple on the yield and yield components of rice on local Tarom variety in Mazandaran province. This research was conducted in 1395 in one of the farmlands of mazandaran province in Qaemshahr district in Zillet village. The experiment was factorial baxsed on randomized complete block design with three replications. Factors included vermicompost in 2 levels؛ control (V0) and applied 5000 kg ha-1 (V1). Superphosphate triple in 3 levels؛ control (P0), applied 75 kg ha-1 (P1), and 150 kg ha-1 (P2) and biologic nitroxin fertilizer in 2 levels؛ control (N0) and applied (N1). Each plot had 4 cultivating lines and the distance between the plant is 25 × 25 cm. The highest seeds yield to the amount of 2640 kg ha-1 vermicompost was obtained from the application of 5000 kg ha-1 which were statistically significant compared to control vermicompost treatments. But from economical point of view application of 5000 kg ha-1 vermicompost that increased yield only 16 kg ha-1 are not recommended. applied Nitroxin treatment raise the yield (2641 kg ha-1) therefore, using this material can raise the rice production. The highest grain yield was obtained from 75, 150 kg ha-1 treatments superphosphate triple respectively 2648, 2649 kg ha-1 which did not have statistical significant difference but there was a significant difference compare to control of this fertilizer. Therefore application of 75 kg ha-1 superphosphate triple is recommended. The highest grain performance was obtained by interaction of vermicompost and nitroxin application with superphosphate triple application of 75,150 kg ha-1 respectivity and 2679, 2686 kg ha-1 which did not have meaningful difference. Also mean compression results shows that application of 5000 kg ha-1 vermicompost after harvest on soil properties increase soil organic matter up to 3.5 percent. Heights phosphorus absorption where achieved at 150 kg ha-1 super phosphate application that was 8.7 ppm. Lowest pH value and highest soil total nitrogen value at the rate of 7.30 and 0.18 percent respectively achived with 5 liter of Nitroxin per hectare.
