| Experiment Title | Effect of espalier architecture on mango cultivars under HDP | ||
| Research Type | Departmental Research | ||
| Experiment Background | Mango crops are terminal bearers and have been cultivated for at least 1500 years. Most commercial orchards are planted conventionally at low densities (100–200 trees/ha) in anticipation of trees growing vigorously, producing large specimens at maturity. Kesar and Sonpari are the most popular mango variety grown in Gujarat. Because of Kesar vigour, trees are traditionally planted at relatively wide spacing 10 x 10 m or 5 x 10 m. Over time, these trees fill their allocated space and reach heights of 6 m or more. In recent years, mango plant spacing have reduced to an average plant spacing of 5 x 5 m or less 2.5 x 5 m. Previous attempts to increase planting density in Kesar failed due to overcrowding and tree vigour requiring excessive pruning that caused yield reduction. Growers using these closer spacing have committed to annual pruning to maintain a smaller canopy size. Generally, canopies are grown to touch in the row to maximize light interception and heights are kept to ~5 m for ease of spraying and picking. However, there are few reports available on the relationship between productivity and light interception in mango orchards. The estimation of productivity and light interception in mango orchards over time is difficult as some cultivars have biennial and irregular bearing patterns. Tree training methods, such as espalier systems, can be employed to manipulate leaf distribution and light penetration within a canopy. These techniques can be tailored to manage the canopy’s architecture and light interception, driving more efficient use of the available light resources. This manipulation of tree shoot architecture changes light interception and distribution within canopy change in an attempt to optimize radiation use efficiency. | ||
