EFFECTS OF CALCIUM AND MAGNESIUM SILICATE IN PRODUCTIVITY OF RICE (Oryza sativa L.) ROTATION OF CULTURE WITH SOYBEAN (Glycine max (L.) Merrill) SYSTEM OF PLANTING IN DIRECT

Abstract

ABSTRACT: The objective was to evaluate the effect of calcium silicate and magnesium yield of rice in rotation with soybeans in no-tillage system in the state of Maranhão. The experiment was established in the area of Rural Union of Imperatriz - Exhibition Park. Initially held collection and analysis for the purpose of soil fertility. After the results of soil analysis, applied agrosilício (silicate of calcium and magnesium) and limestone to correct soil acidity. Last thirty days, microbiolization by 2.6 kg of seeds with growth promoting rhizobacteria (Pseudomonas sp. Burlkoderia and sp.) and proceeded to planting rice in experimental design of randomized blocks with split plots with four repetitions with five levels (0, 1, 2, 4, 8 t ha-1 of calcium silicate and magnesium - Agrosilício). The first results were collected from the emergence and seedling height, followed by reviews of Productivity, Biomass and Mass 100 filled grains. According to the data analyzed, dosages agrosilício not had influence on seedling growth, biomass, 100 filled grains and yield of rice in no-tillage system.   KEY-WORDS: agrosilício, fertilization, germination rate.
