Saline water and bovine biofertilizer in sesame crop

Abstract

Saline stress affects plant growth worldwide.In order toevaluate theinitial development ofirrigatedsesameculturewith saline waterin soil withand withoutbovinebiofertilizer, an experiment it was conductedin full sun, in the experimental areaof theMeteorologicalStation inFortaleza, Brazil, in the period from August to September 2014. The treatments were arrangedin a completelyrandomized design ina factorial 4x 2with eight replications, referring to the electric conductivityof the irrigation water: 0.8; 1.5; 3.0 and 4.5dS m-1, with and withoutgroundbeefbiofertilizerdiluted with waterat a ratio of1: 1levelof 10% ofthe substratevolume. The following variables were evaluated: leaf number, plant height, stem diameter, leaf area, dry matter of shoot, root and total. Saline stress impairs the number of leaves, plant height and shoot dry matter in sesame plants. The bovine biofertilizer attenuated the deleterious effects of salinity on leaf area, stem diameter, root dry matter and total on sesame plants.
