PLANTAS DE GERGELIM CRESCENDO EM SUBSTRATO COM ÁGUA SALINA E BIOFERTILIZANTE BOVINO

Abstract

Sesame seed (Sesamun indicum) is a plant that adapts to high temperatures, low altitudes and expressive lighting, whose cultivation area can be found in Asia, Africa, Central America, South America and Europe. In the present work, the objective was to evaluate the initial growth of sesame plants cultivated in substrate containing saline water and bio-fertilizer. The experiment was carried out in the Department of Phytotechnology and Environmental Sciences of the Federal University of Paraíba (DFCA / CCA / UFPB), in the city of Areia - PB. The experimental design was a randomized block with factorial (5X2), consisting of five saline concentrations (0.5-1.5-3.0-4.5-6.0) and two types of application to the soil (natural fertility Of the soil and organic fertilization) with four replicates, the variables being analyzed stem diameter, plant height, Dickson quality index and total chlorophyll. All the analyzed variables obtained good results with the bovine biofertilizer, however, when they did not use the values decreased. Due to high concentrations of saline water, causing effect on the physical and chemical structures of the soil, affecting the development and metabolism of plants.
