- Abstract
The objective of this research was to evaluate the effect of different irrigation depths associated with different levels of mulching, depending on the behavior of the variables: percentage of total dry matter, water accumulation by plants, leaf dry matter, stem and panicle sorghum (sorghum Bicolor L.). The experiment was conducted at the Fazenda Floresta, belonging to the Federal Institute of Education, Science and Technology (IFCE) - Umirim Campus, from September 2016 to January 2017. The treatments were arranged in subdivided plots, 5 slides x 5 levels coverage with 5 replicates. Irrigations were performed daily and applied slides calculated based on crop evapotranspiration (ETc). The primary treatments were 50, 75, 100, 125 and 150% of the ETc. The secondary treatments were constituted by the application of bagana at levels of 0.00; 2.50; 3.75; 5.00 and 6.25 cm coverage. Finally, the parameters tested showed that by analyzing the results obtained it is possible to perceive that the percentage of dry matter of the leaf was the most sensitive to the increase of the applied blade; The percentage of dry mass of the stem and panicle showed an increasing linear increase with the increase of the irrigation slides, reaching higher values with the highest applied blade; The effect of soil cover presented a non-significant result for the variables analyzed; The percentage of total dry matter and water accumulation in the plant were expressive in the evaluation as variable parameters of production quality control.
