“…The marketable yield we found was in the lower range of values reported in previous desert studies and growing-medias (e.g., Martínez-Blanco et al, 2011;Page et al, 2012;Torrellas et al, 2012;Almeida et al, 2014;Bojacá et al, 2014;Del Borghi et al, 2014;Clavreul et al, 2017;Dias et al, 2017;Ntinas et al, 2017;Canaj et al, 2020;Hu et al, 2021;Torres Pineda et al, 2021). With the rather low yields, the local tomatoes LF is in the upper range of results found in Northern Europe and the UK (Lagerberg-Fogelberg and Carlsson-Kanyama, 2006;Williams et al, 2006), but lower than Italian tomato (e.g., Del Borghi et al, 2014).…”

Worldwide growing demand for food, alongside limited resources and accelerating environmental changes, suggests that future global food security may rely at least partially on unconventional land and production systems, such as built infrastructure located in desert areas. This paper analyses the environmental footprints (water, soil, carbon, material, solid waste, and ecological) of a tomato production system in passive greenhouses, a low-tech growing structure with no artificial heating or cooling. We collected data from 10 farms in the hyper-arid region of the Central Arava, Israel. Our analysis covers the four stages of production up to the overseas export destination and investigates the system's direct and indirect biophysical interactions. The average footprint of a ton of tomatoes is 1,040 kg/t (Material footprint), 94 m3/t (Water footprint), 72 m2/t (Land footprint), 952 kgCO2eq/t (Carbon footprint), 442 kg/t solid waste (SWF) and 243 gha/t (Ecological footprint). Our results indicate that the environmental hotspots can be attributed to universal factors–water production, fossil energy, fertilizers, structures, and road transport, alongside case-specific elements–soil, evaporation, location and the human-factor. Some differences were found when examining the full range of footprints within farms. No correlation was found between the farm's yields and materials inputs or carbon footprint, pointing to the human factor. We discuss the advantages and limitations of the local production system and proposed some improvement strategies.

The mechanism of greenhouse tomato growth and yield under the integrated water and fertilizer of moistube irrigation (MI) is not clear. Thus, to fill the research gap, a completely randomized trial design was used to study the effects of different irrigation amounts (I; to realize different I, the tube working pressure was 1 (I1), 2 (I2), 3 (I3) m) and fertilizer amounts (F, N-P-K: 20%-20%-20%; the F at a single time was 100 (F1), 200 (F2) and 300 (F3) kg/ha) on growth and yield of tomato. The results showed that with an increase in I, the photosynthetic rate (Pn) of leaves and total dry matter mass (TDM) first increased and then decreased, while the nutrition and the flavor indexes of fruit decreased. With an increase in F, the Pn of leaves, the TDM of tomato and the fruit quality increased at first and then decreased. The effects of I on the yield of tomato was higher than that of F. With an increase in I, the partial fertilizer productivity (PFP) increased at first and then decreased, and the water use efficiency (WUE) decreased by 13.96%. With an increase in F, the WUE increased at first and then decreased, and the PFP decreased by 148.97%. The conclusion based on a spatial analysis was consistent with the comprehensive evaluation of yield and water use efficiency, which showed that I2F2 was the best.

“…Irrigation fertilization is a progressive fertilization technique that can replenish water and fertilizer to the crop at regular intervals, thus promoting the uptake of water and fertilizer by the crop 19 . Jing Hu et al 20 designed a comparative experiment to demonstrate that drip irrigation with integrated water and fertilizer technology improves water and nitrogen use efficiency and production stability compared to conventional diffuse irrigation and over-fertilization. Therefore, precise control of water and fertilizer regulation process using reasonable water and fertilizer saving technologies in agriculture is an important tool to achieve sustainable agricultural development.…”

Proportional Integral Derivative (PID) control is the main control method in the process of agricultural water and fertilizer regulation, and its parameter setting directly affects the control effect of water and fertilizer regulation. However, the traditional PID parameters are adjusted manually such as using the critical proportionality method, which is time-consuming and difficult to achieve optimal control effects. To solve the optimal combination of PID control parameters and improve the control effect of water and fertilizer regulation, a partial attraction adaptive firefly algorithm (PAAFA) is proposed in this paper. Specifically, a partial attraction strategy is designed to speed up the convergence of the PAAFA and reduce the oscillation problem at the late stage of the algorithm. In addition, an adaptive inertia weight operator is proposed to balance the global search capability and local search capability of PAAFA and avoid the algorithm from trapping in the local optimum. Subsequently, to test the performance of PAAFA, the algorithm is subjected to a series of simulation experiments and bench tests with the latest methods, i.e., genetic algorithm (GA), Adaptive genetic algorithm (AGA), and firefly algorithm (FA) applied to PID parameter optimization problems. The simulation results demonstrate that the regulation times of the response curve of PAAFA-based PID control are reduced by 22.75%,10.10%and 20.61%, respectively, compared with GA, AGA, and FA. The bench test results show that the PAAFA-based PID control has the smallest relative error, and best control accuracy compared to GA, AGA, and FA, with an average relative error reduction of 3.99, 2.42, and 3.50 percentage points respectively.
