Two new Mycon-hizal products (NR-SH1 and NR-SH2) have just been prepared in Division for Experimental Biology Lab, Institute of Natural Products Chemistry and actually on test in production of several agricultural crops. This paper presents the test results of these two products on Savior tomato grown in pots with different phosphorus application rates (0 g, 1.5 g and 3 g P2O5 per plant). The experiment were conducted in greenhouse of HVA in spring-summer season 2012. The experiment was an-anged in a triplicate completely randomized design (CRD) with two factors (Mycon-hizal products and phosphorus application rate) and 9 treatments. The parameters of physiology, growth, flowering and fruiting, yield components, yield per plant, fruit quality and phosphorus use efficiency were evaluated. The results showed the treatment of NR-SH2 application associated with 3 g of P2O5/plant gave the highest individual yield (1302 g/plant), 1.4 time higher than the control without NR-SH2, and 1.2 time higher than that of NR-SH1. The NR-SH2 application remarkably increased the phosphorus use efficiency at both of two phosphorus rates low and high.
