One of the factors that contribute to the low yield of cultivated rubber plantations in the Amazon, may be associated with physiological constraints inherent to each clone and, one of the ways to improve physiological conditions is the use of production stimulants. With the objective of defining the best bleeding system with stimulation for the clones IAN 4082 and FX3846 grown in areas with AM3 agroclimatic conditions. The project is composed of two experiments, both installed in November 1991, Tracuateua-PA. Each experiment has 4 treatments and 5 repetitions arranged randomly, each plot has ten adult plants, eighteen years old, the clones used are FX3846 and IAN 4082, with the following treatments: 1/2 s d/2 6d/7 (conventional witness); 1/2 sd/3 6 d/7 Et 2.5% p.a.1 (1) 4/y (m); 1/2 s d/56 d/7 Et 2.5% p.a.1 (1) 10/y (m) and 1/2 s d/7 Et 5+ p.a.1 (1) 10/y (m). |
