Effect of Composting Waste on the agronomic parameters of Young Hevea plants (Hevea brasiliensis Muell. Arg.) In West of cote d’ivoire

An agronomic trial lasting four Months was carried out in a peasant environment in order to study the effect of compost made from Chicken Manure, Whether or not combined with urea on the Vegetative Growth of Rubber plants (Hevea brasiliensis Mull Arg.) in bagged nursery. The trial was set up using a Randomized complete block device (BCR) with six treatments which are: T1 (Soil only, absolute control); T2 (Potting soil + 1.30 g of urea (relative control); T3 (0.5 kg of compost mixed with potting soil); T4 (1 kg of compost mixed with potting soil); T5 (0.5 kg of compost mixed with potting soil + 0.65 g of urea) and T6 (1 kg of compost mixed with potting soil + 0.325 g of urea). Data on growth unit, scion diameter (mm) and plant height (mm) were collected monthly from the start of the trial. Plant vigor was also determined. Four months after setting up the experiment, the results showed that adding compost significantly improved the vegetative growth of the plants. These contributions have; therefore, induces a very good vigor of the plants. The T3 treatment (plant having received 0.5 kg of compost mixed with potting soil) gave the best results. This shows that the recovery of waste as a source of organic matter could be a practice to be encouraged among peasants, in particular, rubber tree nurserymen.
