In anna-doizy/mangoviz: CIRAD dashboard for exploring long-term experiments on mango

Objective

The objective of the pruning experiment is to compare the agronomic performance (fruit production, canopy dimensions) of mango trees subjected to different pruning methods.

MangoViz presents fruit production results.

Experimental orchard

• Location : Cirad - Station de Bassin Plat, Saint-Pierre, Reunion Island (21°19’S, 55°29’E, 125m a.s.l)
• Planting year : 2004 (experiment completed in 2022)
• Planting density : 333 trees / ha (6m x 5m)
• Variety : Cogshall
• Rootstock : Maison Rouge
• Experimental design : complete blocks, 3 blocks, 15 trees per elementary plot

Pruning methods

• Unpruned : trees unpruned since planting
• Summer pruning : trees pruned in summer after harvest (end of January - beginning of February)
• Winter pruning : trees pruned in winter at the beginning of flowering (end of July - August)

The trees were pruned every second year from 2012 (trees not pruned before this date).

Studied variables

Each year, the harvest is recorded individually for each tree in the orchard. The ripe fruit is harvested twice a week and counted and weighed for each tree. The variables characterising fruit production are:

• Number of fruit : number of mangoes produced per tree and per year
• Fruit mass : total mass of mangoes produced per tree and per year (in kg)
• Individual fruit mass : mean mass of a mango per tree and per year (in g)

In this experiment, the harvest takes place from the beginning of December to the beginning of February. The year N shown in the graphs corresponds to the harvest from December of year N to February of year N+1.
