“…Chemigation with TFN is able to avoid this problem, since at each application, an amount of the herbicide is accumulated near the emitter's outlet, forming an acidic environment which can inhibits root growth and, consequently, its intrusion into the emitters orifice (Cai et al, 2019;Lima et al, 2014). This technique has been widely recommended as a preventive in field measure, especially in crops extremely sensitive to water stress, such as sugarcane cultivars (Dalri et al, 2021;Lima et al, 2014;Simões et al, 2018).…”

The Trifluralin (TFN) is a pre-emergent herbicide which is widely used in agriculture. Usually, this pesticide is directly applied to the soil, where it can remain for long periods or can be transported. In this sense, knowing the dynamics of an herbicide soil transport is essential to avoid environmental contamination problems and risks to human health. Thus, this study aims to model and simulate TFN movement on soils with two different textures, a sandy loam and clay loam soil. It was considered that the herbicide was applied via chemigation trough a subsurface drip irrigation system, under a non-steady regime. Therefore, the transport parameters of TFN in these soils and physical-hydric characteristics of these were used, while the physical environment modeling were conducted using the Hydrus 2D software. The results showed that both in sandy and clayey soils, the TFN tends to be retained by the soil, close to where it was applied, not exceeding a layer greater than 2.5 mm outside the dripper radius, even in more favorable conditions such as the presence of irrigation. Finally, it could be concluded that this herbicide movement in the soil is of low potential, due to this product high solid-liquid partition coefficient (Kd), even in sandy soil, which has low cation exchange capacity (CEC).

“…However, the combination of moderate reductions in irrigation water with varieties more tolerant to the deficit of water can provide savings in irrigation costs without reducing the sugar produced. Dalri et al (2021) observed that the correct choice of sugarcane cultivar in an irrigated production system may increase productivity by more than 50%.…”

“…Based on the hypothesis that water consumption by the plants differs between crops, cultivars, regions, environmental and climatic conditions and soil moisture as well as between irrigated and non-irrigated systems (Liu et al, 2007;Fader et al, 2010;Silva et al, 2013;Dalri et al, 2021), the use of water efficiency indexes is essential to define cultivars that are responsive to different crop management practices. Tayade et al (2020) observed that the correct choice of a sugarcane cultivar and the irrigation management may increase water use efficiency by more than 40%.…”

The aim of the study was to evaluate the effect of irrigation depths, via subsurface drip, on the technological quality, productivity, and water use efficiency (WUE) of sugarcane cultivars. The experimental design was of balanced blocks with 12 blocks and two factors: cultivars (CTC 4, IACSP93-3046, RB86-7515, IACSP95-5000 and IAC91-1099) and irrigation depths (dry, deficit and supplementary). From the estimated evapotranspiration (ETc), irrigation depths equivalent to 100% of crop ETc were defined for the supplemental treatment and 50% for deficit. The amounts of sucrose in the juice (POL) and the cane (PC) did not differ among the cultivars; however, additional irrigation provided higher values of the evaluated parameters. The purity levels of all treatments were superior to those recommended (85%) and differed between the cultivars. In the supplementary irrigation regime, the IAC91-1099 cultivar had the highest total recoverable sugar value (TRS), equal to 165.62 kg Mg-1, and the highest yields of stalks and sugars, 157.02 and 26.01 Mg ha-1, respectively. The WUE was superior in the dry regime for the CTC4 and RB86-7515 cultivars, and these were considered tolerant to the water deficit. The deficit irrigation provided average gains in the yield of sugarcane and sugar similar to supplementary irrigation; consequently, there were substantial reductions in water use and irrigation requirements in addition to energy savings.

“…However, as soil fertilization might be carried out during the drought season, the use of liquid fertilizer seems more adequate to promote great nutrient accumulation by the plant and sugarcane growth ( Ullah et al., 2019 ) due to the soil moistening promoted by the volume of liquid fertilizer applied (800 to 1000 L ha −1 ). This hypothesis is based on experiments that have investigated sugarcane fertilization, which promotes gains in biomass production and in the technological quality of the raw material ( Rhein et al., 2016 ; Gutiérrez-Miceli et al., 2017 ; Dalri et al., 2021 ). To the best of our knowledge, no published study has investigated the use of liquid NPK fertilizer compared to the solid source on sugarcane biomass production and N, P, and K accumulation.…”

IntroductionThe contrasting weather conditions throughout the sugarcane harvest period in south-central Brazil (April to November) influence fertilization management in sugarcane ratoon.MethodsThrough field studies carried out over two cropping seasons, we aimed to compare the performance of sugarcane at sites harvested in the early and late periods of the harvest season as a function of fertilizer sources associated with application methods. The design used in each site was a randomized block in a 2 x 3 factorial scheme; the first factor consisted of fertilizer sources (solid and liquid), and the second factor consisted of application methods (above the straw, under the straw, and incorporated into the middle of the sugarcane row).ResultsThe fertilizer source and application method interacted at the site harvested in the early period of the sugarcane harvest season. Overall, the highest sugarcane stalk and sugar yields at this site were obtained with the incorporated application applying liquid fertilizer and under straw applying solid fertilizer, with increments of up to 33%. For the site harvested in the late period of the sugarcane harvest season, the liquid fertilizer promoted a 25% higher sugarcane stalk yield compared to the solid fertilizer in the crop season with low rainfall in the spring, while in the crop season with normal rainfall, there were no differences between treatments.DiscussionThis demonstrates the importance of defining fertilization management in sugarcane as a function of harvest time, thereby promoting greater sustainability in the production system
