“…In the interaction between the sources of variation, the increases in organic matter dosages together with irrigation water salinity levels interfered significantly (p<0,01) in fresh shoot mass. In a study by Souza et al (2018) in the cotton crop, only the stem diameter parameter presented significant interaction when evaluating salinity levels and organic matter doses.…”

“…Regarding the number of leaves and fruits, the evolution was similar to the growth of the plants in height and diameter of the stem, it is observed that the organic matter doses from 4% provided increases in these variables with the emission of leaves and fruits by the cotton plants. For Souza et al (2018) the addition of organic matter promotes increased growth and cotton production.…”

“…Cotton cultivation with the naturally colored fiber has been gaining prominence in the national scenario, especially due to the environmentally correct character of its cultivation, which dispenses with the need for artificial dyeing. In this context, many studies have been developed to better understand the productive aspects and conditions of culture (Souza et al, 2018;Pedro et al, 2016).…”

This work evaluated the development of colored cotton submitted to irrigation water of different salinity levels and organic matter doses from tanned manure. The experimental design was completely randomized in a 4 x 4 factorial scheme with 3 replications, totaling 48 experimental plots. The factors studied were 4 doses of organic matter (1, 4, 7 and 10%) and four levels of irrigation water salinity (0.26; 1, 2 and 4 dS m-1). The variables analyzed were plant height, stem diameter, number of leaves, number of fruits and fresh shoot mass. Significant effect of organic matter was observed on all studied variables, with a positive response on the increase of all variables as a function of increasing doses of organic matter. The isolated effect of salinity was significant for all parameters evaluated, except for the number of leaves, with significant reductions of 6.03; 3.27; 5.23; 6.94% in the parameters: plant height, stem diameter, number of fruits and shoot fresh weight respectively, for each unit increase of irrigation water salinity. The interaction between the variation sources studied had a significant effect only for fresh shoot mass, where the highest average for this parameter was observed at 10% organic matter dosage at irrigation water salinity level of 1.0 dS m-1.

“…Organic matter application in substrate composition in the adequate quantity to plants is important and can influence their growth and development. According to Souza et al (2018), it is fundamental to carry out research to provide data on the amount of organic matter required to meet the nutritional needs of the crop under semi-arid conditions.…”

With the occurrence of prolonged droughts in the Brazilian semi-arid region, water scarcity directly influences agriculture in this region, so that water reuse and bovine manure application become a viable alternative for pepper production. In this context, the present study aimed to evaluate the sustainable production of chili peppers (Capsicum frutescens) under levels of irrigation with treated wastewater and doses of bovine manure. The following bovine manure doses were considered: D1 (0% manure and 100% soil), D2 (10% manure and 90% soil), D3 (20% manure and 80% soil), D4 (30% manure and 70% soil), D5 (40% manure and 60% soil) and D6 (50% manure and 50% soil), based on volume. Three levels of irrigation were applied, based on the water requirement of the crop (WR), namely: 100% WR (L1), 75% WR (L2) and 50% WR (L3). Production variables and physical characteristics of the produced peppers were evaluated. Pepper production (g plant-1) increased as 10% of bovine manure were added in substrate composition. Increasing concentration of bovine manure and using 50% WR provided favorable conditions for the organic production of chili pepper.

“…Inhibition of growth in plants subjected to salt stress was a consequence of changes in leaf gas exchange (gs, E, Ci, and A). In addition, another factor that contributed to the reduction in SD was the decrease in the osmotic potential of the soil solution caused by excess soluble salts in the root zone, which limits the absorption of water by the roots, causing the plant to reduce stomatal opening as a mechanism to reduce water loss, which leads to a reduction in cell turgor and, as a consequence, a decrease in cell expansion and plant growth (Souza, Lima, Gheyi, Nobre, & Soares, 2018). Corroborating the results obtained in this study, F. V. da S. Sá et al (2015) evaluated the initial growth of custard apple (Annona squamosa L.) seedlings as a function of water salinity (ECw from 0.3 to 4.8 dS m -1 ) and observed that an ECw higher than 0.3 dS m -1 caused negative effects on the growth in stem diameter.…”

The semi-arid region of Northeastern Brazil has water limitations in terms of both quantity and quality, with salt stress as a limiting factor for increasing yield in most crops. In this context, the present study aimed to evaluate cell damage, gas exchange, and growth of custard apple under salt stress and potassium fertilization. The research was carried out at the Experimental Farm of CCTA/UFCG, in São Domingos-PB, Brazil. A randomized block design was arranged in a 2 × 5 factorial scheme, with two levels of electrical conductivity of irrigation water (ECw; 1.3 and 4.0 dS m-1) and five potassium doses (10, 15, 20, 25, and 30 g of K2O per plant per year). Water salinity of 4.0 dS m-1 negatively affected the stem diameter and number of leaves in custard apple at 179 and 210 days after transplanting (DAT). The highest relative growth in stem diameter in the period of 179-245 DAT was obtained in plants irrigated with 4.0 dS m-1 water and fertilized with 20 g of K2O per plant. Potassium doses of up to 30 g of K2O resulted in a higher percentage of cell damage and relative water content in custard apple leaf tissue. Water saturation deficit decreased with the increase in K2O doses in plants irrigated with water of 1.3 dS m-1. Irrigation with 1.3 dS m-1 water and estimated K2O doses ranging from 16 to 22 g per plant resulted in an increase in stomatal conductance, transpiration, CO2 assimilation rate, and instantaneous carboxylation efficiency in custard apple plants at 210 DAT.
