“Métodos de siembra en arroz (Oryza sativa L), con tres niveles de fertilización a base de Fósforo, Magnesio y Boro, en Babahoyo”

VIII. SUMMARY The present work was executed in the properties of the farm "Linda María", property of Mr. Raúl Paredes Solano, located in the enclosure "La Guadalupe" of the canton Montalvo, County of Los Ríos. Nine treatments and three repetitions were used. The investigation had as objective to evaluate crops systems in combination with fertilizers with phosphorus, magnesium and boron, in the production of rice. The siembra of the rice you made with the variety F-09 in experimental units of 20 m2. All the treatments were distributed in a design of divided parcels. For the evaluation of stockings the test was used from Tukey to 5 % significance. At the end of the cycle it was evaluated: plant height, macollo number and panicule for square meter, days to flowering and harvests, panicule longitude, number of grains for panicule, weight of 1000 grains, grain yield for hectare, relationship grain-straw and economic analysis. The obtained results showed bigger statistical variation with the use from the crops system to continuous jet, fertilized with 60 kg/ha of P + 40 kg/ha Mg + 4 kg/ha B and their interaction. One didn't have significancia in the variable days to flowering and days to crop, achieving bigger quantity the system of voleo with dry seed, without fertilization P-Mg-B, with their interaction and being harvested sooner. The biggest grain yield was obtained with the treatment crop system to continuous jet fertilized with 60 kg/ha P + 40 kg/ha Mg + 4 kg/ha B with 6334,33 kg/ha. The dose of the fertilizer 60 kg/ha of P + 40 kg/ha Mg + 4 kg/ha B caused increments of 36 % in the grain yield. The analysis to foliate reported levels adapted in all the treatments, except for the copper that was faulty. The plants sowed in the system to voleo with dry seed, tried with more 60 kg/ha of P + 40 kg/ha Mg + 4 kg/ha, they had the best utility with $661,03.
