Studies conducted on high-density plantings have shown them to have several benefits. These include higher yields, reduced weeding and pruning costs, and soil erosion control. Close spacing has also been observed to result in more efficient utilization of nutrients and water. Despite these advantages, high-density plantings have high establishment costs in terms of high amounts of inputs. High-density planting are possible only in areas that have relatively high rainfall or where irrigation facilities are available. Field operations in high-density plantings are made difficult due to extensive interlocking of branches, particularly with tall traditional varieties. This paper discusses some of the work that has been conducted on high-density plantings and sugests some areas that may require further work.
