“…For leaf area, the leaf area integrator model LI 3100 was used to measure the total leaf area of each plot (pot). The determination of the dry mass of the aerial part of the sesame was performed at the moment of cutting, placing the aerial part in a closed circulation oven at 65ºC, for 72 hours to dry them and later weighing them on a semi-analytical scale [17]. The root volume was determined with a 500mL graduated cylinder, in which the root of each plant was placed inside the cylinder with a known volume of water, and the excess volume difference observed after placing the root equals its volume [17].…”

Sesame is an oilseed, nutritionally important in the world, for its seeds are rich sources of protein and calcium. Fertilizer management is fundamental for the development of this crop and consequently to increase its productivity. In this context, this research aimed to evaluate the initial development of sesame under nutrient omission in the Cerrado of Mato Grosso, Brazil. The experiment was conducted under controlled conditions in a greenhouse, at the Federal University of Rondonópolis. The soil used was Oxisol and the crop used was black sesame. The design was in randomized blocks, with five treatments (absence of nitrogen, absence of phosphorus, absence of potassium, complete fertilization and control (absence of nutrients)) and four repetitions. The variables analyzed were pH, chlorophyll index, plant height, number of leaves, stem diameter, leaf area, aboveground dry mass, root volume, and root dry mass. The pH variable showed a statistical difference 45 days after emergence. The chlorophyll index showed a difference between 30 and 45 days after emergence. The stem diameter, leaf area, plant height, number of leaves, aboveground dry mass, root volume, and dry mass showed a difference among treatments. The absence of nitrogen, phosphorus, and potassium significantly affects the initial development of sesame.
