Abstract

This study was conducted in the orchard of the Rural Polytechnic Institute for Training and Applied Research (IPR / IFRA) in Katibougou to assess the growth and production of solo papaya (Carica papaya L., 2n = 18) in Sudano-Sahelian zone of Mali as well as the effects of the hormone and manuring formulas. A split plot device, comprising 2 factors with 3 levels of variation each, was used. The main factor was  the hormone represented by gibberellic acid (GA3) and the synthetic auxin Trichloro phenoxi acetic acid (2-4-5-T). The secondary factor was  the manure formulas consisting of organic manure (OF); organic + mineral manure (FOM) and Liquid manure (FL). The test was  characterized by 9 treatments (GA3 + FO, GA3 + FOM (Organic and mineral manure), GA + FL (Liquid manure) ; 2-4-5-T + FO, 2-4-5-T + FOM, 2-4-5-T + FL; SH (No hormone) + FO (Organic manure) ; SH + FOM and SH + FL). It was carried out  on a ferruginous tropical hydromorphic soil with a strong flapping of water tables. Each treatment was applied to 3 rows of 4 plants. It appears from the study that the application of the combination of hormones (GA3 + 2-4-5-T) and the formula of organic manure + mineral manure stimulates growth and that the application of hormones (GA3 and 2-4-5-T) on the papaya tree makes it possible to reduce planting - flowering cycle and early fruit setting.

Key words: Biomass, flowers, height of plants, number of leaves, planting-flowering.
