“…Analysing scenarios with variation in productive systems can measure sufficient economic results for decision-making related to the study (Pereira et al, 2018;Oliveira et al, 2016;Araújo et al, 2018). In the research, the indicators corroborate the implementation of business strategies and the direction of coffee grower investments.…”

The defects that drying in concrete yards impose on coffee beans and the search for gourmet coffee production have prompted the emergence of new drying technologies. This work verified the technical and economic feasibility of drying coffee with dehumidified air with a refrigerating capacity of 422,908.7 J s -1 , compatible with static capacity dryers equal to 75 m 3 . Considering the sale price of coffee, the cost of electric energy acquisition, the monthly interest rate and maintenance time, expenses that are equivalent to the depreciation of the concrete yard, a central compound rotational design was considered with 28 tests for the feasibility analysis, including the internal rate of return, net present value and the return on investment. The results showed that in the electric drying units, the dried coffee presents fewer broken and defective beans and has higher retention in a N o . 17 sieve. With a higher beverage quality and a price 12.11% higher, drying with dehydrated air showed a PBD of 2.27 years and a return of US$ 2.49 million. The optimisation results were 98.98% desirable. It was concluded that it is economically feasible to dry coffee with dehydrated air and without using a concrete yard.

“…Several are the benefits that can be observed in the practice of irrigation, the main ones being: (i) increased productivity with water use efficiency two to three times higher than those obtained with rainfed agriculture; (ii) reduction of the unit cost of production; (iii) use of the agricultural area throughout the year with up to three harvests; (iv) intensive use of machines, implements and labor throughout the year; and (v) increase in the supply of food and other agricultural products on a regular basis throughout the year (OLIVEIRA et al, 2016;GRAFTON et al, 2018).…”

Considering the scenarios with reduction of water availability, the need to increase water use efficiency and crop yield, the objective of this study was to evaluate the effect of reducing the evapotranspiration of the main irrigated crops on productivity. Data from the years 2005 to 2016 for carrot, garlic, potato, sugarcane, bean, maize, soybean, wheat, coffee and cotton crops grown in the Brazilian states of Bahia, Minas Gerais, São Paulo, Goiás, Distrito Federal and Mato Grosso were collected. The crops were irrigated by central-pivot irrigation and drip irrigation systems, and irrigation management was performed using IRRIGER® software. With the information on potential crop evapotranspiration (ETpc) and crop evapotranspiration (ETc), it was possible to obtain a reduction of ETpc (%) for all crops. For all scenarios, these data were confronted with crop productivity and regression models were fitted. It was concluded that the maximum reductions of ETpc (%) without affecting productivity are 5% for garlic and potato, 12% for maize, 13% for bean, 15% for wheat, 20% for soybean and cotton, 25% for sugarcane and 30% for coffee.

“…It has been reported by researchers that studies have generally saved irrigation water but have significantly reduced yield. The use of drip irrigation in the world has been accepted for many years, but subsurface drip irrigation has gained momentum for different plants, melon (Sharma et al, 2014), grassland (Finger et al, 2015), ornamental plant (Elhindi et al, 2016), sugar cane (Silva et al, 2016), broccoli (Oliveira et al, 2016) in recent years. Studies on the use of surface/subsurface drip irrigation for rice have been emphasized in recent years, but research on the subject is still needed.…”

Rice is one of the most applied irrigation waters applied plant among cultivated plants since it is grown in water or in saturated soil conditions in a significant portion of the growing season. This study was aimed to determine the effects of rice grown on water use, development, yield and some yield parameters using of both separately and jointly water retention barriers and subsurface drip irrigation methods in Enez, Edirne, Turkey in 2017. Methods and Results: Four different treatments were applied: ponding ((control(C)), subsurface drip irrigation system (SDI), ponding + water retention barrier (C+WRB) and SDI+WRB in this study. Subsurface drip irrigation laterals were placed 10 cm deep from the soil surface and the WRB was placed at 30 cm deep. Plants were irrigated with a constant water height of 10-15 cm on the soil in C and C+WRB treatments, 20% ± 5% of the available water retention capacity is consumed without exposure to water stress in SDI and SDI+WRB treatments, the field capacity is completed. WRB and SDI applications significantly affected the irrigation water amount, grain yield and yield components of rice. The yield and irrigation water amount according to the treatments varied between 321-715 kg da-1 and 751-2444 mm, respectively. Conclusions: In comparison to the control treatment, water saving was achieved by 27%, 50%, 69% in C+WRB, SDI and SDI + WRB treatments, respectively. Despite this, when marketable yield values are analysed according to the control treatment, it has increased by 10.8% in C+WRB, and decreased by 48.8% and 40.7% in SDI and SDI + WRB treatments. The water retention barriers and subsurface drip irrigation practices used in the study have been shown to reduce the use of irrigation water in rice production. Significance and Impact of the Study: It can be said that these methods have the potential to be used especially in arid and semi-arid regions where water is limited or inadequate.
