Aluminum toxicity reduces the nutritional efficiency of macronutrients and micronutrients in sugarcane seedlings Ciência e Agrotecnologia
Borges,Carolina Eggers; Cazetta,Jairo Osvaldo; Sousa,Francisco Bruno Ferreira de; Oliveira,Kamilla Silva.
ABSTRACT Although the effects of aluminum on the content and accumulation of mineral nutrients in crops have been studied, but nothing is known about its effect on the nutritional efficiency of sugarcane. Therefore, this study aimed to evaluate the effect of aluminum toxicity on nutritional efficiency, nutrient accumulation, and growth of sugarcane seedling. Sugarcane seedlings of the genotype IACSP95-5000, obtained from one-bud mini-cuttings (3 cm), were used in the test. Seedlings were subjected to treatments in a completely randomized design, with eight Al concentrations in the nutrient solution (0, 10, 20, 30, 40, 50, 60, and 70 mg L−1) and three replicates, totaling 24 experimental units. Analyses determined the contents, accumulation, and absorption,...

Biomass production and phosphorus use of forage grasses fertilized with two phosphorus sources Rev. Bras. Ciênc. Solo
Ramos,Sílvio Júnio; Faquin,Valdemar; Rodrigues,Carlos Ribeiro; Silva,Carlos Alberto; Boldrin,Paulo Fernandes.
A major constraint to agricultural production in acid soils of tropical regions is the low soil P availability, due to the high adsorption capacity, low P level in the source material and low efficiency of P uptake and use by most of the modern varieties grown commercially. This study was carried out to evaluate the biomass production and P use by forage grasses on two soils fertilized with two P sources of different solubility. Two experiments were carried out, one for each soil (Cambisol and Latosol), using pots filled with 4 dm³ soil in a completely randomized design and a 4 x 2 factorial scheme. The treatments consisted of a combination of four forage plants (Brachiaria decumbens, Brachiaria brizantha, Pennisetum glaucum and Sorghum bicolor) with two P...
