Item Avaliação do sistema radicular de pinhão manso em diferentes níveis de irrigação localizada(2015) Costa, Fernando Rezende da; Silva, Marciana Cristina da; Evangelista, Adão Wagner Pêgo; Rosa, Flávio de Oliveira; Alves Júnior, José; Silva, Vinícius Vilela daThe culture of jatropha and an alternative in the production of vegetable oil to the Brazilian Biodiesel Program becoming an important alternative source of income. In order to evaluate the distribution of the root system of plants jatropha (Jatropha curcas L.) with two years of planting in the Cerrado Goiano irrigated region with various levels of irrigation located by micro. Management was performed based on the values of the evaporation tank Class A (ECA) to the irrigation treatments N 0 = control; N 80 = 80% of ECA; N 120 = 120% of ECA). The samples were collected at five locations, two in the row and in three perpendicular distances of: 0.25 m, 0.75 m and 1.5 m) in relation to the stem, and at three depths: 0.0 to 0 25 m, 0.25 to 0.50 m 0.50 to 1.0 m, with 15 samples per plant with four replicates totaling 240 samples. The jatropha root showed higher concentration in the layers of 0 to 40 cm with projection 60 cm in diameter in relation to the stem, even with the presence of larger diameter in this range roots. There was the presence of significant volume of fine roots to 60 cm deep can be recommended to adopt this depth for irrigation purposes.
