This study evaluated the production of Inga laurina (Sw.) Willd seedlings in 110 and 280 cm3 tube containers growing doses (0, 3, 6 12 kg m-3) controlled-release fertilizer (CRF) (15-09-12) their performance at 5 months after outplanting. The experiment was conducted using a randomized split-plot design, 2 x 4 arrangement (tube volumes CRF doses). Stabilized sewage sludge from urban origin used...

Fertigation is one of alternative measures not only to ensure crop yield but also improve nutrient use efficiency. In this work, we evaluated growth and yield, uptake nitrogen efficiency upland carrot. To do our goal, various basal fertilizers (single chemical slow release) fertigations were employed based on the result soil diagnosis, detail was as follows; basal:fertigation = 100:0, 50:50, 30...
