| Abstract The type of environment and substrates quality in seedlings production are essential for the production of productive plants under field conditions. In order to determine the best environment and substrate for seedlings production of two tomato cultivars (IPA 06 and Santamélia), two experiments, completely randomized and arranged in subdivided plots with five replicates, were conducted under the environmental conditions of Boa Vista, Roraima, Brazil. Treatments consisted of the association among five environments (A1 - greenhouse, A2 - Chromatinet ® 35% red, A3 - Chromatinet ® 50% red, A4 - Chromatinet ® 35% Silver and A5 - Chromatinet ® 50% Silver) and four substrates S1 - OrganoAmazon®; S2 -OrganoAmazon® + PuroHumus®; S3 - OrganoAmazon® +... |

| Abstract 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... |
