Macronutrient uptake in sorghum plants in different arrangements.

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