Given the importance that the species Euterpe precatoria exerts on the market, tied to a few studies referring to the initial phase of the crop, the objective was to evaluate the production of seedlings of single assai palm (Euterpe precatoria Mart.) submitted to increasing doses of nitrogen and potassium. The seedlings were arranged in a randomized block design in a 5x5 factorial scheme. The first factor comprised nitrogen doses (0, 15, 30, 45, and 60 mg dm-3 of N) and the second potassium (0, 40, 80, 120, and 160 mg dm-3 of K), applied in installments, 20, 40 and 40%. Plant height (PH), stem diameter (SD), and the number of active leaves (NL) were evaluated at 90, 180, 240, and 300 days after pricking out, as well as ideal installment scans using the data obtained. Evaluations of the dry mass of the stipe (EDM), leaf (LDM), shoots (SDM), root (RDM), and total (TDM) were also evaluated at 300 days after pricking out, and the relationship between PH/SD and SDM/TDM was established. The data were submitted to univariate analysis and regression analysis. It was observed that the interaction between N x K was not significant, thus presenting the isolated effect of both. It was concluded that the K doses influence the stem diameter at 180 and 240 days and the PH/SD ratio. N presents increasing linear responses in almost all variables except PH/SD, and N split in the proportions of 30%, 30% and 40% for seedling production up to 300 days after pricking out is recommended. |

This paper describes the performance of addition rates of basaltic breccia and agricultural gypsum on clay stabilization and nutrients release of a solodic Planosol from a degraded borrow area located in Southern Brazil. A leaching experiment was carried out in PVC cylinders filled with 1.5 kg of soil (C horizon), in which two chemical amendments were added in three different proportions: a) basaltic breccia in 7, 14 and 21 Mg ha?1 doses; b) agricultural gypsum in 7, 14 and 21 Mg ha?1 doses; and c) a standard soil, without chemical correction. Distilled water (300 mL) were added every 7 days for 20 weeks and the pH, electrical conductivity, calcium, magnesium, sodium and potassium contents and the water-dispersible clay were analyzed in the collected leachates. Gypsum was more efficient than basaltic breccia to promote clay flocculation, even at the lower rate (7 Mg ha?1). The application of basaltic breccia up to 21 Mg ha?1 reduced the amount of nutrients released directly to the soil solution, reducing soil leaching. The application of basaltic breccia at the dosage of 7 Mg ha?1 was able to reduce more than 65% of the water-dispersive clay from the degraded solodic Planosol. |
