Abstract
A study of the influence of different planting dates on the agronomic behavior of GT 1 clone rubber plants was conducted in southwestern Côte d'Ivoire. The agrophysiological and climatic data necessary for the study were collected on the experimental site of the SCASO. This test includes two sub-tests of the same methodology but with different implementation dates. One test was set up in June 1991 (under test 1) and the other in June 1992 (under test 2), according to a Fisher experimental block design, of three treatments (early, normal, and late) with four repetitions. Two latex harvesting systems were applied to all treatments; S/2 d/4 6d/7 ET 2.5% Pa 1 (1) 6/y, from the first to the second year and from the fourth year, the system, S/2 d/4 6d/7 ET 2.5% Pa 1(1) 10/y. The analyzes revealed that the rate of trees present in the plots (86.91 ± 0.27%), the vegetative growth tapping (2.36 ± 1.24 cm.year-1) and the average annual yield (2018 ± 763 kg.ha-1.year-1) were good, and were influenced by the fluctuation of certain climatic factors. Despite good rubber productivity, the physiological profile remained good with low LEM (2.41 ± 1.85%), regardless of the date of planting. The proper timing of plantation establishment is early and normal planting.
