Six commercial products developed on the basis of hormonal bioestimulantes were evaluated to determine their effect on yield and quality of grain of rice transplantation, and determine the relationship, benefit / cost of using such products compared with normal handling no use of hormones.The treatments were T0 = Control or control (without application of hormonal products); T1 = gibberellic acid 4% (ryzup); T2 = gibberellic acid 9.4%, in table-tas (Berelex); T3 = L-cysteine ​​5% + 0.1% foleico acid (Ergostim); T4 = 0 .009% cytokinin gibberellic acid + 5% + indole-3-butyric 0.005% (Stimulate); T5 = ammoniacal nitrogen 85% + phosphoric acid 32% + soluble potassium 5% + iron 0.1 + zinc 0.05% + humic acid (powerrgizer) and T6 = cytokinin 0.012% + N, P, K, 5.36% + (S, B, co, Fe, Mg, Zn) 2.04% 1 (triggerr).This study was conducted at the Agricultural Experimental Station "El Porvenir" -of National Institute of Agricultural Research. Juan Guerra District, San Martin province and region. The experimental design was randomized complete block design with four replications v seven treatments. duncan test was used to 0.05 Probabilities-ness to make multiple comparisons.Planting took place on November 24, 1996, and 27 days after transplantation. Cultural practices were the usual for rice cultivation conditions Marrow Transplant-te in the area. The application of hormonal bioestimulantes was shaped leaf, can bom-ba backpack, two times of application, at 28 DDT (tillering) and 68 DDT (cotton jersey).They did not observe significant differences in grain yield between the treatments-tos studied. T3 treatment produced the greatest number of panicles / m outperforming significantly. T1, T5 and T6 treatments. However, he did not show superiority over treatment without application (T0).As for the effect of hormonal products on the physiological crop cycle, T5 treatment induced a statistically significant improvement at the beginning of ripening grain compared to the control treatment and 3 hormonal treatments.As for the characteristics of grain, only significant effects on the translucency of grain in treatments T4 and T5 which presented statistical-mind smaller percentage of grains were observed with white pansa, the control treatment (T0).None of the studied hormone treatments produced a higher return the control treatment, and they all showed a negative rate of return, to excep-tion of T3, which showed a positive rate of return of S / .0.11 for every new sun additional invested.
