Extração de Macronutrientes no Sorgo Granífero em Diferentes Arranjos de Plantas

The objective of this study was to evaluate the macronutrient exported grains and remaining componentsof the aerial parts of sorghum at different plant spacings. The experiment was conducted at the Experimental FarmMocambinho, located in the irrigated perimeter Jaíba, MG. The cultivar chosen was the DKB 599 and planting densitiesused were 100, 150, 200 and 250000 plants per hectare in row spacings of 25, 50 and 75 cm. The experimental designwas randomized blocks in factorial scheme 3 (spacing) x 4 (thickness) with four replications. The experimental plotconsisted of four rows 5 m long, considering how useful area the two central rows were evaluated in the levels ofmacronutrients from the area of plant. The nitrogen and sulfur exported in the remaining components of the aerialparts of sorghum are influenced by plant spacing, while the calcium and nitrogen for grain exports are affected by plantspacing. Since the seeding rate does not affect the macronutrient and grains exported by the remaining components ofthe shoot.
