Efectos de fertilizantes foliares a base de extracto del alga Ascophyllum nodosum, sobre el rendimiento de variedades arroz (Oryza sativa L.) bajo riego, en la zona de Babahoyo

VIII. SUMMARY The present research work was carried out on the grounds of the Experimental Farm "Palmar" of the Faculty of Agricultural Sciences of the Technical University of Babahoyo, located at Km 12 of the Babahoyo-Montalvo road. The area has a humid tropical climate; With a height of 8 m.s.n.m., located between the geographical coordinates 79º 32' of western longitude and 1º 49' of south latitude, having an average annual precipitation of 1845 mm, with temperature of 24,32 ºC annual average. As seed material, the rice varieties INIAP-14, INIAP 15 and FSL-09 were used. The experimental design was divided into three treatments (rice varieties INIAP 14, INIAP 15 and FSL 09), five sub - treatments (Algadul + N - P - K, Stimplex + N - P - K, Algadul, Stimplex and Conventional Witness N-P-K with several doses) and three replicates. For the evaluation and comparison of means of the treatments, the Tukey test was used at 95% probability. For the execution of the test, all practices and agricultural tasks that the crop required for its normal development, such as soil analysis, soil preparation, planting, weed control, phytosanitary control, fertilization whose N-P doses -K mentioned were established based on soil, irrigation and harvest analysis. To accurately estimate the effects of treatments, the data were taken from days to flowering and physiological maturation of grain, height from plant to crop, panicle length, number of tillers and panicles per square meter, number of grains per panicle, Grain - straw ratio, thousand grain weight, yield per hectare and economic analysis. From the above results, it was determined that the SFL 09 strain using Algadul + N-P-K flowered precociously; While the variety INIAP 14 using Algadul and Stimplex maturated in higher time; The highest plant height was recorded in the SFL 09 variety by applying Stimplex + N-P-K and the interaction of INIAP 15 with Stimplex showed a longer panicle length; The highest number of tillers / m2 was reported by the SFL 09 variety using Stimplex and in terms of panicles / m2 the sowing of the INIAP 14 variety was excelled with the use of Algadul + NPK: The use of variety SFL 09 with the use of Stimplex + NPK showed greater number of grains / panicle; While the highest grain - straw ratio was obtained with SFL 09 by applying Stimplex + N - P - K. And the highest weight of 1000 grains, yield in kg / ha and economic analysis reached the SFL 09 variety with the application of Stimplex + N-P-K product with a net profit of $ 1146,49
