“…In this way, castor bean can also be produced in the northernmost regions of Chile, particularly along the coastline [Fig. 3(a)]; although there is not a commercial cultivar for Mediterranean climate, 37 the growing demand for castor oil as a replacement for conventional petrol‐based products makes its expansion to other places or regions possible 100 . To establish castor bean for oil production, agronomic evaluation and studies of genotype × environment interaction are mandatory, hence field experiments must be realized in the short and medium term 37 .…”

Industrial crops are becoming increasingly relevant as raw materials for different goods and services. Although there are many oilseed crops with industrial purposes, data about their production in Chile are scarce because the definition used by the Office of Agricultural Studies and Policies places agro‐industrial and industrial crops in the same category. Here, we review the available information about 12 industrial oleaginous crops at different levels of development (four native, two adventive and six introduced crops). Most of these crops have been evaluated for or are related to biodiesel production, despite the lack of commercial biodiesel production in Chile. Jojoba was the first industrial oilseed produced commercially in Chile; however, every year its production area decreases, and currently it does not exceed 100 ha. Sunflower and rapeseed, which are the first generation of raw materials for biodiesel production, have been poorly studied in Chile despite the large number of studies available on them worldwide. Camelina and castor bean have recently been studied; the former is produced in the south, while the latter is produced on the coastline in northern Chile. Further research is needed to improve the production and adaptation of these oilseed crops to climatic conditions in Chile; moreover, a new market must be opened to produce and commercialize their oils. Oilseed species native to Chile have not been extensively studied, and they represent an interesting option suitable for production under Chilean climatic conditions; this is particularly true for guindilla and chañar, because both can grow under different abiotic stresses. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…The results indicate that the sunflower headers cutting and conveying systems performed better in castor bean harvesting compared to the common cereal header. The latter may induce more mechanical stress on plants, leading to the detachment of capsules from the raceme and resulting in higher impact seed loss [31].…”

The moisture content during harvesting significantly influences post-harvest losses, encompassing factors that collectively diminish both the quantity and quality of agricultural produce. These factors involve pre-harvest sprouting, mechanical damages and susceptibility to diseases at post-harvest. To mitigate the risks associated with excessive moisture, farmers have to employ proper harvesting techniques such as using a combine harvester. The combine harvester proves invaluable by efficient harvesting, threshing and winnowing various crops like rice, corn, wheat, sunflower and pulses directly in the field. This streamlined process not only saves time and reduces the need for human labour but also lowers overall work costs for farmers. Additionally, the utilization of these machines enhances agricultural productivity, ensuring a more efficient harvesting process and contributing to greater profitability in farming practices. Consequently, effective moisture content management becomes essential for minimizing losses and preserving seed quality. A multipurpose nature of a combine harvester minimizes the need for manual labour in harvesting, leading to a reduction in workforce requirements, time expenditure and effort. Consequently, this enhances overall productivity. The objective of the present review is to describe the effect of moisture content on crop, machine and operational parameters on seed quality of combine harvested crops and discussed the effect of moisture content on mechanical damage of combine harvested seed crop and its germination potential and seedling vigour.

“…For example, the Helianthus 12000 series sunflower header developed by the company Capello in Italy (Capello Srl, Via Valle Po, 10012100 Cuneo, Italy), the Falcon series sunflower header developed by the company Rostselmash in Russia (Rostselmash, Rostov Nadon, Rostov Oblast, Russia), the G3 series sunflower header developed by the company Fantini in Italy and the ZIECLER series sunflower header developed by the company Dragotec in Germany (Dragotec International GmbH, Hub 7, 84329 Wurmannsquick, Germany.) are based on the principle of a corn header [13][14][15][16]. At present, the research on the harvesting of sunflower is still in its infancy in China.…”

This study aims at the problems of high labor intensity, high cost and high loss rate of mechanical picking of seeds, low mechanization level and difficulty to guarantee the quality of picking plates in the process of picking edible sunflower. Based on the principle of manual plate taking, a plate taking control system for a sunflower harvesting table was designed. The principle of taking the plate of the edible sunflower harvesting table was analyzed. According to the actual operation requirements, the overall scheme of the sunflower plate control system is determined, and the control strategy of imitating artificial low-loss harvesting is designed. To reduce the grain loss in the process of taking the plate and improve the control accuracy of the system on the movement speed and displacement of the key components in the process of taking the plate, a trapezoidal acceleration and deceleration control algorithm is designed as the control algorithm of taking the plate. The working performance of the plate control system was verified with the absolute error, relative error and total loss rate of the harvest as objectives. Bench and field verification experiments were both carried out. The bench experiment showed that the speed error of the plate parts was not more than 0.028 m/s. In the bench experiments of the device, the maximum positioning error was 1.25 mm, the average relative error was only 0.94% and the grain loss rate was not more than 2.26%. Its result showed that the system algorithm was reliable, the positioning accuracy was high and the plate taking operation can be completed well. The field verification experiment showed that the forward speed of the unit was in the range of 0.4~0.8 m/s, and the total loss rate of harvest was less than 5%. When the forward speed is 0.6 m/s, the minimum harvest loss rate is 2.32%, which indicated the control system meets the requirements of sunflower harvesting operation.
