“…It should be noted that water productivity is directly proportional to biomass yield and inversely proportional to irrigation depth. Guimarães et al [74] and Magalhães et al [75] corroborate the results obtained. These authors also verified that the increase in irrigation depths caused a linear reduction in water productivity in different lettuce varieties.…”

“…The literature disagrees, regarding the effect of irrigation depths on the shoot fresh mass of lettuce crop. Guimarães et al [74] applied irrigation depths between 50% and 125% ETc and verified quadratic effect on different varieties of lettuce. The authors observed that the irrigation depth for replacement of 100% ETc was the one that maximized the values of the fresh biomass of the different lettuce varieties.…”

The objective of this study was to evaluate the adsorption capacity of orange pomace biochar, applying its benefits in irrigated agriculture. For this, a low-cost system for tertiary treatment using biochar was developed. The objective was also to compare the physicochemical and microbiological attributes of irrigation water with the limits established by the legislation. The impacts of wastewater from the filtration system on the soil and on the agronomic and biological characteristics of the lettuce crop were assessed. Biochar was produced in a muffle furnace and characterized by thermogravimetry and scanning electron microscopy (SEM). The experimental design was randomized blocks, in a 5 (irrigation depths) × 5 (combinations of water sources and fertilization) factorial arrangement, with three replicates. It was found that the use of biochar as a filter material improved the microbiological quality of wastewater. The water sources used in irrigation did not cause changes in soil salinity. Fertigation using wastewater that passed through the filtration system positively affected the agronomic characteristics of lettuce, with no need for top-dressing fertilization. Lettuce leaves produced in the experiment were acceptable for human consumption, according to the standards of Resolution-RDC No. 12, of 2 January 2001, of the National Health Surveillance Agency (ANVISA).

Recycled paper has the potential to be used as a mulch for vegetable production and can be adopted for the cultivation of Italian zucchini. However, there have been no studies about the water savings or crop coefficient values used in irrigation management in this system; therefore, there is a need for more research. In view of the above, this study aimed to evaluate the effects of recycled paper mulch on evaporation and evapotranspiration in Italian zucchini and to determine the crop coefficients in its developmental stages. The study was carried out in two cultivation cycles conducted at the Lysimetric Station in Viçosa, MG, Brazil. The experiments were installed in a randomized block design with four replicates. Four lysimeter cultivation treatments were applied: without mulch (C); with recycled paper as mulch (CP); with only recycled paper (P); and with Bahia grass (G). Irrigation and drainage measurements were performed daily to calculate the crop and reference evapotranspiration, and thus the crop coefficient (Kc) values. The following characteristics were evaluated: fruit yield, NDVI and water productivity. For the cultivation of Italian zucchini using paper as mulch, Kc values of 0.54, 0.77 and 0.44 and Kcb values of 0.15, 0.45 and 0.18 are recommended for the initial, intermediate and final stages, respectively. NDVI can be used to estimate the Kc values for Italian zucchini. The use of recycled paper as mulch reduces the water consumption of Italian zucchini.

“…The total irrigation required (TIR, mm) was calculated (Eq. 2) based on crop evapotranspiration and drip system efficiency (90%), similar to Guimarães et al (2019). RIR -real irrigation required (mm); Ei -drip system efficiency (dimensionless); and, ETc -crop evapotranspiration (mm) with the same value as the RIR.…”

This study aimed to evaluate the effects of different colors and management of polypropylene non-woven fabric coverings and two different localized irrigation systems on the physiological characteristics and yield of industrial tomatoes. The experiment was installed in a randomized block design arranged in a split-plot scheme with four replications. Surface and subsurface drip were used in the plots, and five plant cover strategies with non-woven fabric in the subplots: i) without non-woven fabric; ii) coverage with white non-woven fabric; iii) coverage with white non-woven fabric, removed between 30 and 60 days after transplanting the seedlings; iv) coverage with red non-woven fabric; v) coverage with red non-woven fabric, removed between 30 and 60 days after transplanting. Photosynthesis, transpiration, electron transport rate, stomatal conductance, carbon concentration, total fruit yield, and water use efficiency were evaluated. ANOVA and the Scott-Knott test were used. Transpiration is favored by the white non-woven fabric and the stomatal conductance by the white and uninterrupted red one. However, the tomato yield is not influenced by the coverings, except for the red one, removed only between 30 and 60 days after transplanting, which is the worst condition for industrial tomato production. Surface and subsurface irrigation can be used with the same efficiency.
