“…e effect of harvest date study on crops is a scourge concerning not only sugar beet but also other fruits and vegetables and has been addressed by many researchers. Nadori et al [18] studied the influence of rootstock and harvest date on fruit quality of mandarin during cold storage, Esmaeilpour and Shakerardekani [19] studied the effects of early harvest times on nut quality and physiological characteristics of pistachio (Pistacia vera) trees, Doua and Shid [20], for their part, studied the influence of harvest season on volatile aroma constituents of two banana cultivars, Feyem et al [21] studied the influence of harvest date on seed germination of some varieties of rainfed rice, and finally, Dibi et al [22] determined the harvest period of sweet potato varieties.…”

Choice of the harvest date is one of the foundations of vintage quality and good-yield sugar in sugar beet. However, it is difficult to define the harvest date and more precisely the date of maturity of beet roots, in an exact and absolute way. Indeed, maturity is divided into several stages and degrees depending on environmental and climatic conditions such as temperature, precipitation, geographic area, and others. The present study evoked the effect of three harvest dates (at esteemed maturity, 7 days after maturity, and 15 days after maturity) on the technological quality parameters, namely, sucrose, nitrogen, potassium, and sodium, using the most popular chemometric method, principal component analysis (PCA). To do this, samples from the Tadla irrigated perimeter were used. The results of exploratory analyses by the application of PCA clearly showed the influence of harvest date, in an important way, on the three quality parameters, composition of sucrose, potassium, and sodium. But, for nitrogen composition, there were negligible variations between samples.

“…Another factor that determines the pistachio nuts quality is the time of harvest [2]. In this sense, it was observed that the sooner the pistachio harvest the higher the contents of potassium, calcium, magnesium, nitrogen and protein but the lower the yield [5]. Other researchers have linked the quality and production of pistachio nuts with the water regime and the rootstock used [6,7].…”

The objective of this work is to evaluate the agronomic, phenological, nutritional quality and organoleptic characteristics of pistachios (Pistacia vera L.) based on the NDVI (Normalized Difference Vegetation Index) calculated in the phenological stage of nut filling from Sentinel satellite imagery. Based on this index, three pistachio tree orchards were studied and classified into two levels of vigour: high and low. The results obtained have discriminated the production per tree, which is strongly related to yield. Regarding the nutritional quality parameters, significant differences were not observed between vigour levels, although the most vigorous trees have shown nuts with a higher percentage of fibre and protein. In terms of phenology, there have not been differences between trees of different vigour, only a slight advance of some phenological stages has been observed in several high-vigour trees. Triangular tests have been made successfully to discriminate the origin of the dry nut and the vigour of the trees. In conclusion, for a given nut quality within a given orchard, the NDVI is a good index to classify different areas according to productive capacity and can be useful to apply variable management, irrigation and fertilization according to vigour.
