“…A Plant height (cm) B Initial growth of zucchini irrigated with saline water in soil with biofertilizers It should be highlighted that the superiority shown by these biofertilizers indicates that they increase soil fertility and function as a plant growth promoter. The results obtained in this study corroborate the data presented by when using crab biofertilizer in corn culture and by Nascimento et al (2019) by fertilizing the cotton culture with an organic source.…”

“…Sousa et al (2018), working with soybean crop, presented a result in line with this study, that is, the bovine biofertilizer increased a larger stem diameter. Similarly, Nascimento et al (2019) also observed an increase in the diameter of the stem when fertilizing the cotton culture with an organic source.…”

“…Ressalta-se que a superioridade apresentada por esses biofertilizantes revela que esses fertilizantes orgânicos aumentam a fertilidade do solo e funcionam como promotor de crescimento de plantas. Tal resultado corrobora com os dados apresentados por ao utilizar biofertilizante de caranguejo na cultura do milho e por Nascimento et al (2019) ao adubar com fonte orgânica a cultura do algodão.…”

“…It is possible that the inhibition of the leaf area was caused, mostly, by the toxic effect of the salts absorbed by the plants, by the low capacity of osmotic adjustment of the culture, or by the reduction of the total water potential caused by the increase in the saline concentration (MUNNS;TESTER, 2008).…”

“…É possível que a inibição da área foliar tenha sido provocada, em maior parte, pelo efeito tóxico dos sais absorvidos pelas plantas, pela baixa capacidade de ajustamento osmótico da cultura ou pela redução do potencial total da água provocado pelo aumento da concentração salina (MUNNS;TESTER, 2008).…”

Zucchini culture is slightly sensitive to salinity and is among the ten vegetables of highest economic value, with characteristics of precocity and easy cultivation. These characteristics are some of the reasons for the expansion of its cultivation among small producers. Thus, the objective was to evaluate the effect of different levels of salinity in the irrigation water and biofertilizer types on the initial growth of the zucchini (Cucurbita pepo L.) culture. The experiment was carried out in the full sunlight in a randomized block design, in a 5x2 factorial arrangement. The treatments consisted of a combination of five types of biofertilizers (quail, sheep, mixed, bovine, and crab) and two salinity levels of the irrigation water (0.8 and 2.5 dS m-1), with five replicates. At 30 days after transplanting, the following variables were evaluated: electrical conductivity of the substrate, plant height, number of leaves, roots length, stem diameter, leaf area, chlorophyll content, dry mass of the aerial part, root dry mass, and total dry mass. Salt stress negatively interferes with the accumulation of zucchini plant biomass. Quail, bovine, and sheep biofertilizers are more efficient about plant height, number of leaves, and stem diameter. The sheep biofertilizer attenuates the salt stress for the dry mass of the aerial part, the root, and the total dry mass.

Treated domestic sewage (TDS) can contribute to plant nutrition and improve crop production. However, there are no data for its use in coloured cotton under a deficit or excess irrigation in combination with potassium fertilization rates (KRs), mainly under semiarid tropical conditions. The research was conducted using a randomized complete block design in a factorial scheme (5 × 5, irrigation regimes vs. potassium rates), plus an additional treatment as the control ((5 × 5) + 1). The treatments consisted of five TDS irrigation regimes (50, 75, 100, 125, and 150% of crop evapotranspiration—ETC) and five KRs (0, 50, 100, 150, and 200% of the local crop recommendation), plus a control—CT— (irrigated with fresh water at 100% ETC and fertilized according to the local crop recommendation) and four replications. The optimal crop yield, water use efficiency, and potassium use efficiency were obtained when TDS was applied as a deficit irrigation treatment of 75% of ETc or as full irrigation (100% of ETC) and when associated with moderate increases in K fertilization. These treatments also resulted in a better fibre quality when compared to the CT, meeting or exceeding the requirements of the textile industry. Therefore, moderate deficit irrigation with TDS is indicated as an important strategy to save fresh water and to reduce the use of fertilizers, while having the potential to increase profit margins for cotton production in tropical semiarid regions.
