Root system of eggplant irrigated and dryland cropping in different systems

Abstract

Aiming to evaluate the density and distribution of roots of eggplant with supply of organic fertilizer and chemical application will be submitted and no drip irrigation method in ultisol, there was an experiment in Aquidauana-MS. The design was randomized blocks with split plots, using four blocks. Treatments used in the plots corresponded to eggplant and without irrigation and the subplots consisted of organic fertilizer and chemical industries. Irrigation was performed based on the evaporation of the Class A pan and through tensiometer. The organic and chemical fertilization using urea and organoeste respectively, were performed at 45, 60 and 75 days after transplanting (DAT). The gathering of roots were done at 113 DAT for this using an auger hole, and taking samples at three distances from the plant stem (zero, 0.2 and 0.4 m) and four soil depths (0.00-0.10, 0.10-0.20 0.20-0.30 and 0.30-0.40 m) were then washed, taken to oven and weighed on an analytical balance. It follows that the effective depth of the root system of drip irrigated eggplant by both fertilization is a maximum of 0.20 m.
