Samborondón Canton, whose southern province of Guayas Latitude is 1°52' 48'' west and equal length 80º05'13.3'' at an altitude of 35 m The main objective is: to evaluate the effect of phosphorus on tillering and yield of rice (Oryza sativa) variety lNlAP 15 specific objectives determine the agronomic performance of the rice variety lNlAP 15 subjected to different doses of phosphorus; check best dose of phosphorus in the development and production of rice variety lNlAP 15, set up a number of tillers per plant and per plot study and perform cost/benefit analysis of treatments. For this study, a randomized complete design (DBCA) with 4 treatments and 5 replicates per fertilizer levels blocks are used to determine the difference between the test measures multiple range Tukey (P ≤ 0.05) was applied. In assessing the study variables have in plant height (cm) and number of spikes Variety lNlAP treatment T2 15 (21 kg N - 2 kg P - 18.5 K Dosis/ha-1) is statistically superior to other treatments with 97cm and 20 spikes/plant. For the variable grains per panicle and grain length (mm), treatment T1 Variety lNlAP 15 (UREA - 21 kg N Dosis/ha-1) is statistically and numerically superior respectively, 144.7 and 7.5 grains per panicle mm long. Treatment T3 Variety lNlAP 15 (21 kg N - 3 kg P - 18.5 K Dosis/ha-1) has the best grain weight 25.9 (g). Variables for number of tillers, yield per plot ( kg) and yield per hectare (kg) throws the best result Variety lNlAP treatment T2 15 (21 kg N - 2 kg P - 18.5 K Dosis/ha-1) tillers with 15.5, 20.9 kg per plot and per hectare yield of 4732.3 kg -1. The best utility and cost/benefit ratio for the treatment T1 is lNlAP 15 (UREA - 21 kg N Dosis/ha-1) and 0.71 to $ 29.29, in that order.
