“…Egypt, Iran, Saudi Arabia, Iraq, Pakistan and Algeria are the main producers of dates and they provide 75% of the total World production. Most of the agricultural operations are done manually, which is laborious and time consuming (Mazloumzadeh and Shamsi 2007). Any new economic method that can reduce these operations is welcomed by date growers (Al-Suhaibani et al 1993).…”

Precision agriculture can be cost effective for date palm groves because the tree positions are known and fixed, the groves are mostly structured and many of agricultural operations are applied manually. Therefore, the new technology tools of precision agriculture are not essential. This study was done to improve date palm yield using maps of the variation in tree properties. Data on five Mozafati tree properties, such as sex, age, yield, visual appearance and fruit length were measured and recorded for each tree in five groves near the city of Bam in Iran. Tree positions were defined and the above properties were mapped. It was difficult to judge patterns in the variation because of tree to tree variability. Therefore, the Mamdani fuzzy inference system (MFIS) was used to classify the productive trees based on yield, fruit length and visual appearance, and to produce a tree total quality map (TTQM) for each grove. Based on the TTQM the trees were graded as excellent, good, medium, poor and very poor. The trees were also graded by the date growers who were experts. The evaluation for all groves by MFIS showed 87% general agreement with the results from the human expert indicating that it is a feasible method for classifying date palms based on quality. The results indicted that there are young and old trees in these groves that need different treatments, such as the amount of fertilizer required. Some date growers have low incomes, therefore, the overall TTQM is suitable for them because they can identify which trees have the greatest needs and apply limited resources to only those. This case study illustrates the use of computer and mathematical software to enhance date palm production and reduce the costs.

“…The movement speed of the platform towards the bottom was 6 m/min, and the faster the cylinder moved, the higher the intensity of the platform lifting. [14] found a descent velocity of 0.25 m/s for a 10-meter-high platform. [23] found that the descent time of a robot used in oil palm harvesting was 17.2 s/m.…”

“…[13] found that the ascent velocity of a platform operated by the hydraulic device of the tractor was 0.1 m/s. [14] found that the suitable climbing speed is 0.41 m/s, and the best design should reach a height of 13.5 meters. [15] found that the rise time of the telescopic platform was 0.2 m/s.…”

A field experiment was carried out in one of the orchards of Al-Qassim district in Babel Governorate to find out the ability of a locally manufactured platform to serve palm trees by working in flat and uneven orchard land, palm tree heights of 4, 8, and 12 meters, and it performs pollination, pruning and harvesting services. The time of ascent and descent, the palm service, and the palm/hour productivity were measured. A randomized complete block design with three replications used a split split-plot arrangement. The nature of the land (flat or uneven) represented the main plots, the height of the palm trees (4, 8, 12) meters, the sub-plots, and the palm service operations (pollination, pruning, harvesting) of the sub-sub plots. The data were analyzed and compared according to the L.S.D test at the probability level of 0.05. The results indicated that there is a significant effect of the palm height factor and the type of service factor on the studied characteristics. The highest time for ascent and descent was 101.22 and 50.86 seconds, respectively, at the height of 12 meters, and the highest time for serving the palm tree was 95.40 seconds/palm for the pruning process, and the least productivity was 7.33 palm trees/hour for the pruning process. There was a significant interaction between the palm tree’s height and the land’s nature regarding productivity characteristics. There was a significant difference between the height of the palm tree and the type of service with both times of ascent, descent, and service of a palm tree. Based on the previous, it is possible to use the locally manufactured platform in palm groves to reduce the suffering of palm farmers from the difficulty of performing the necessary operations to serve palm trees, especially those of high altitudes.

“…Harvesting is a critical stage that requires time and skilled labor. The use of machines, as normally done in the United State of America, can reduce harvesting costs by 50% [43], so various harvesting techniques and prototypes have been proposed over time to facilitate the farmers in this task.…”

Date palm is important cultivation for arid regions and its cultivation is expanding, though challenges to its modernization still remain partially unsolved: the mechanization of the most important farming operations is not fully developed, though various attempts have been carried out over time. The aim of this review paper is to provide an overview of the most characterizing research works directed at mechanizing farm operations for date palms in the three main morphological zones: crown, trunk, and roots. Various parameters such as maneuverability, working height, payload, cost, and working capacity have been considered by different authors for the performance analysis of their proposals, though safety is considered by all the main drivers of the research. The projects that have been developed and the relevant results can provide a useful reference for those who want to engage in further developing this sector or in applying some of the more effective proposed solutions. In order to promote this field of research, these attempts of mechanization of date palm cultivation need to concretize it with commercialised devices and machines mainly by strengthening the channels of technology transfer between the university and the socio-economic world on the one hand, and by encouraging the industry to adopt these research results, on the other.
