“…Recently, pecan cultivation presents a globalized panorama, not limited only to the region of origin, but is found in several regions. Countries such as China, Argentina, Uruguay, Peru, Chile and Brazil are also pecan nut producers [9]. Figure 2 presents the current pecan nut production scenario worldwide.…”

Considering a large amount of high potential materials coming from the processes to obtaining pecan nut, there are important future perspectives to enable an increase of using pecan materials. For this, structural support and the development of scientific research are needed to reuse the wastes in an environmentally friendly way. Thus, the aim of this scientific research is to present a detailed literature overview regarding the characterization of pecan waste materials, the main applications and technologies used to add value to these materials. The study is fundamentally based on the scientific literature related to obtaining products from pecan wastes and their application in food-related areas. The lack of sufficient data on the proposed theme requires a properly structured approach to provide a clear perspective on the subject and to highlight the current limitations. It is evident that pecan culture has presented a prosperous context with respect to the world and Brazilian production. The scientific literature presented many studies that employ the approach of using remaining pecan materials. Thus, it is clear the range of fields that apply the residuals for the most diverse purposes, which enables them to add value to pecan coproducts.

“…The pecan [Carya illinoinensis (Wangenh.) K. Koch (Grauke 1991)] is a nut native species of the United States and Mexico, but it has been commercially grown in several countries in South America, including Uruguay, Argentina, Chile, Peru and Brazil, and also countries in other continents, as China, Egypt, South Africa and Australia (Sparks 1991, Wells 2011, Thompson & Conner 2012, Castillo et al 2013, Wells 2017a, Bilharva et al 2018.…”

Pecan trees require adequate soil moisture conditions to produce nuts with good yield and quality. Irrigation should be an important considered practice in orchards management plan, mainly in regions with water defi cit periods. The objective of this research was to evaluate irrigation on pecan nuts growth and yield. This study was conducted in Uruguay, during the fast development phase until the pecan nuts harvest. Three irrigation treatments were used: 0 L (control), 70 L and 140 L plant -1 of water every two days, applied via drip irrigation in seven-year-old pecan trees of the cultivar Success. The number of nuts per cluster and nuts' diameter and length were evaluated during nut growth. After harvesting, peeled nuts' width and length were measured, and after peeling, the kernel length, width, height and fi lling and the kernel and peel percentage were evaluated. According to the results, it was possible to identify that periods of water defi cit during pecan nuts development affected the kernel fi lling stageand size. Irrigation in pecan plants provides greater dimensions and nuts mass.With the use of 140 L plant -1 , there was an increase in the nut mass of more than 100% in relation to the nuts from plants without irrigation.

“…Ela é considerada uma espécie multipropósito, podendo ser utilizada para exploração de madeira e ornamentação (Beltrame et al, 2012). No entanto, no Brasil, o cultivo da nogueira-pecã está principalmente atrelado à produção de frutos, sendo o Rio Grande do Sul (RS) o maior produtor do país com cerca de 5 mil hectares de área plantada, seguido pelo Paraná (PR) e Santa Catarina (SC) (Bilharva et al, 2018).…”

“…A Barton e a Shawnee estão entre as principais cultivares produzidas na Região Sul do país (Fronza et al, 2018). A escolha da cultivar deve ser um dos principais fatores a ser considerado antes da implantação de um pomar de nogueira-pecã, pois poderá influenciar a produção e rendimento para o produtor, velocidade de desenvolvimento da árvore, maior resistência a doenças, precocidade de produção, características do fruto e forma de polinização (United States Department of Agriculture, 2015; Bilharva et al, 2018).…”

The choice to cultivate is one of the main factors to be considered before the implementation of the pecan orchard (Carya illinoinensis). This is because it may influence factors such as production and yield to the producer, speed of development of the plant, greater resistance to diseases, early production, pollination and fruit characteristics. Its production stems from cross-pollination, as the male and female organs do not juxtapose in the maturity time. The degree of overlap between pollen release and pistil receptivity varies with the mode of cultivation. Thus, to ensure the possibility of high yields, two or more modes of cultivation should be performed concurrently through cross-pollination. This study aimed to compare the phenological development of two pecan crops in the four cardinal quadrants of an orchard located in southern Brazil. The experiment was carried out in a rural property in an orchard aged five years in the municipality of Morro Redondo (RS). Greater development was observed in the length of the branches in the south quadrant, with an average of 80.54 cm. In conclusion, in our study, the phenological development and growth of pecan branches occur differently due to the cardinal position. The branches in the west quadrant are smaller in length and diameter. In the Barton cultivar, the branches positioned in the South quadrant were larger in diameter and length, influencing the phenological development. Already, the cultivar Shawnee has not completed its production cycle. In addition, floral development in the 'Barton' branches occurred earlier in those in the western quadrant.
