This research is based on the comparison of methods of traditional transplanting and transplanting in rows on the growth and yield of rice cultivation (Oryza sativa L.). It was conducted during the period September 2016 to January 2016, in the experimental plots in the sector Vainillas, District Biavo Under, Bellavista Province, Department of San Martin. Comparing two transplanting methods: traditional transplanting and transplanting in rows divided with four plots (P1, P2, P3, P4). The variables studied were: theoretical work capacity (CTT), effective working capacity (CET), field efficiency (Ef) in the soil preparation in both methods, water demand growing, efficiency of water use, tillering ability (CnM), height plant (HT), flattens or toppling plant (Lg), panicles fertility (St), maturation (Mat), panicle length (PNL), number of panicle per plant (Npp), number of grains per panicle (Ngp) , number of voids per panicle grains (Nvp), weight of thousand grams (PMG), grain yield (kg / ha) and industrial quality required to achieve each stage of development and financial analysis Benefit/Cost (B/C). Once the study is completed, the variables in study achieved the following results: the theoretical capacity of the machine soil preparation transplant system in rows with 0.47 ha/h and traditional was 0.44 ha/h effective capacity working methods of transplanting in rows and traditional was 0.33 and 0.22 ha/h, respectively. Field efficiency obtained was 71.68% to 50.51% for transplantation in rows and traditional. The total volume of water applied under the transplanting in rows was 6601.1 m3/ha and in the traditional 14180.7 m3/ha. The water use efficiency obtained was 0.51 kg/m3 for traditional and 1.33 kg/m3 for transplanting in rows. The ability of tillering (CnM) to 81 DDS was higher (31.4) in 30x30 compared to traditional (24.9). Plant height (HT) 106 DDS was higher (117.1 cm) 30x30 compared to traditional (111 cm). The obtained optimum fertility rate (90.27) under 30x30 and (86.15) under traditional transplanting, 30x30 panicle length was highly significant with a value of (26.62) unlike traditional with (25.15). The transplanting in rows system (30x30) had the highest yield with 8799 Kg/ha it followed by traditional with 7255 Kg/ha. Most industrial quality was low transplantation in rows (30x30) with 78% and the lowest in traditional with 66.7%. The financial analysis B/C profitability and determine the best transplanting in rows system is 30x30 with 1.81 B/C and 68.58% return and secondary traditional transplanting with 1.09 B/C and 48.00% return. The demand for water, water use efficiency, crop development and financial analysis Benefit/Cost responded positively in the production of rice cultivation transplanting in rows system unlike traditional transplanting.
