Special Issue Information
Dear Colleagues,
Agriculture is historically vital to the prosperity of civilizations and has withstood the pressure of the environment and population growth due to genetic improvement and plant management. Most agricultural crops are subject to environmental stresses such as drought and salinity. In many cases, these stresses act together, limiting crop productivity. In this view, innovative management strategies can improve the productivity of agricultural crops subjected to unfavorable environmental conditions, such as drought and salinity.
This Special Issue focuses on developing and evaluating management strategies for crops subjected to drought and salt stress. For this reason, it welcomes studies of an interdisciplinary nature from research fields related to agriculture, including horticulture, genetics, plant ecophysiology, irrigation, soils, and plant nutrition. Research articles will cover various agricultural crops and solutions for growing them under drought and salt stress conditions. Original research articles and reviews will be accepted.

Title: Increasing tolerance to salt stress in lettuce cultivars by applying elicitors
Authors: Miguel Ferreira Neto
Affiliation: Universidade Federal Rural do Semi-Árido
Abstract: Lettuce productivity can be limited by the concentration of salts in both water and soil. We evaluated the influence of salt stress tolerance elicitors on photosynthesis, yield, and ion homeostasis of lettuce cultivars. The research was conducted in a greenhouse with pots containing 12 dm3 of soil classified as Oxisol. For irrigation, a mixture of reject brine with an electrical conductivity of 9.0 dS m-1 and supply water was used, obtaining an electrical conductivity of 4.0 dS m-1. The experiment was conducted in a randomized block design, in a 3 x 5 factorial scheme, with five replications. The first factor corresponded to three cultivars of curly lettuce: SVR 2005, Simpson, and Grand Rapids. In the second factor, the lettuce cultivars were submitted to five combinations of treatments, including the foliar application of elicitors: E1 - irrigation with low salinity water (0.53 dS m-1, control); E2 - irrigation with high salinity water (4.0 dS m-1, saline stress); E3 - saline stress + exogenous application of ascorbic acid (50 µM L-1); E4 - saline stress + exogenous application of gibberellic acid (50 µM L-1); and E5 - saline stress + exogenous application of salicylic acid (50 µM L-1). The irrigation with saline water of 4.0 dS m-1 decreased the assimilation rate of CO2, stomatal conductance, growth, and biomass production of the salinity-sensitive cultivars SRV 2005 and Simpson. Salicylic acid attenuated salt stress in cultivar SRV 2005, improving growth, stomatal conductance, photosynthesis, and maximum efficiency of photosystem II.

Title: Morphophysiology of soursop seedlings irrigated with fish farming effluent under NPK doses
Authors: Francisco Vanies Da Silva Sá
Affiliation: Universidade Federal Rural do Semi-Árido (UFERSA)
Abstract: Soursop is a tropical fruit grown in the Brazilian semiarid region, where there are frequent problems of quantitative and qualitative scarcity of water for irrigation. The utilization of alternative water sources, such as fish farming effluent, can increase water availability; however, it poses risks due to its high salinity levels. Therefore, new management strategies need to be investigated. Thus, the objective of this study was to evaluate the morphophysiology of soursop seedlings subjected to irrigation with saline fish farming effluent at different NPK doses. The experiment was carried out in a greenhouse, employing a randomized complete block design, in a 2 x 5 factorial scheme. The factors consisted of two irrigation water source (local supply water with an electrical conductivity of 0.5 dS m-1 and fish farming effluent with an electrical conductivity of 3.5 dS m-1) and five doses of NPK (25%, 50%, 75%, 100%, and 125% of the fertilizer recommendation 100:300:150 mg dm-3 of the N:P2O5:K20), with four repetitions. The seedlings were grown in containers with 2 dm3 filled with sandy soil for 90 days after sowing. The seedlings were evaluated for growth, biomass accumulation, photosynthesis, NPK and sodium. The superior growth and photosynthetic performance of soursop plants irrigated with fish farming effluent are associated with their ability to maintain ionic homeostasis between sodium and potassium. Soursop seedlings respond differently to NPK fertilization when they are irrigated with low-salinity water and fish farming effluent. The recommendation for NPK fertilization for soursop seedlings irrigated with low-salinity water is 95:285:143 mg dm-3 of the N:P2O5:K20, and for soursop seedlings irrigated with fish farming effluent is 69:207:104 mg dm-3 of the N:P2O5:K20.
