The objective in this study was to determine the nutrient contents in Myrciaria dubia plants in function of five K2O doses (0, 40, 80, 120 and 160 kg ha-1) applied through fertigation. Leaf dry matter (LDM), total dry matter (TDM), and leaf nutrient contents were evaluated. The LDM and TDM were higher in plants subjected to the dose of 160 kg ha-1 of K2O, with 52.44 g and 302.69 g, respectively. Leaf N and K contents were 22.15 and 9.48 g kg-1 in response to 160 kg ha-1 of K2O. The mean P, Ca and S contents were 1.6, 17.89 and 1.61 g kg-1, respectively, and the content of Mg2 + decreased from 5.62 to 2.74 g kg-1 at the dose of 0 and 160 kg ha-1 of K2O, respectively. The B, Mn and Fe contents decreased from 136.5 to 100.0, 346.24 to 248, and from 142.06 to 97.35 mg kg-1 at the dose of 0 and 160 kg ha-1 of K2O, respectively. The mean Cu and Zn contents were 3.81 and 40,54 mg kg-1, respectively, at the K2O doses. The nutrient content determined in the leaves of M. dubia were adequate for the development of the species in the first year of cultivation, presenting the following decreasing order: N> Ca> K> Mg> P = S> Mn> B> Fe > Zn> Cu. |

Fields studies were conducted in 2004/2005 in order to evaluate the effects of tillage on nutrient content in aboveground biomass of two peanut cultivars, cultivated in rotation after mechanical harvested sugarcane and pastures. These trials were carried out in two types of soils; Oxisol and Ultisol, respectively in Ribeir?ao Preto and Mirassol, S?ao Paulo State, Brazil. The experimental design was split-plot with four replications. Tillage treatments (conventional, minimum and no-tillage) were main plots while sub-plots were peanut genotypes IAC-Tatu ST (Valencia market-type, erect growth habit, red seed coat, maturity range around 100 days after planting) and IAC-Caiap´o (Runner market-type, prostate growth habit, pink testa, maturity range more than 135 days). From 15 to 90 days after emergence, samples of leaves and stems were harvested, dried, weighted and ground to determine macro and micronutrient concentration. At 75 days after sowing, the cultivar IAC-Caiap´o showed higher contents of N, P, K, Cu, and Zn while IAC-Tatu presented higher concentrations of Ca, Mg, and S. Zn content was higher in conservation tillage than in conventional, mainly in Oxisoil for both of cultivars. |
