“…TDS and deficit irrigation are crucial alternatives to optimize the production of irrigated coloured cotton in semiarid tropical regions, saving water and fertilizers, and leading to a more sustainable irrigated agriculture [31][32][33]. Our results showed that the use of TDS in a full irrigation regime (100% ET C ) and at a deficit irrigation regime (75% ET C ), even without K fertilization, increased seed cotton productivity by 51 and 32%, and the lint cotton yield by 37 and 21%, respectively (Figures 4 and 5), compared to the control treatment (100% ET C with freshwater plus mineral fertilization).…”

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.

“…Water replacement above 50% did not increase SFY in any region (Figure 7), suggesting that full irrigation might not be a useful strategy. Still, there are several studies in the literature showing that the practice of irrigation promotes an increase in the sugarcane yields (e.g., Gonçalves et al, 2019), especially when levels of water requirement are based on ETc (Dias et al, 2019).…”

Determining the proper crop water requirement associated with the optimum amount of green cane trash blanket (GCTB) on the soil is one of the most discussed issues for sugarcane growers. In this context, this research aimed to evaluate the effects of different amounts of GCTB and ETc replacement scenarios on sugarcane yields across key producing regions in Brazil using the agricultural production systems simulator (APSIM). The sugarcane APSIM (APSIM-Sugar) was parameterized and validated for sugarcane in Brazil, compared to both 100% GCTB cover and bare soil, both fully irrigated. After validation through field data, the APSIM-Sugar model was used to simulate 25 different scenarios with varying GCTB amounts and irrigation demands in 12 regions of Brazil for a 30-year period to estimate stalk yield. Overall, modeled and field data agreed very well regarding soil moisture and biometric and physiological variables, achieving strong modeling efficiency. For most producing regions of Brazil, interaction between the factors did not increase stalk yield significantly, and up to 50% of ETc replacement resulted in the highest increases in stalk yield, with the greatest improvement between 0-25%, producing an average increase of 30 Mg ha-1 per year. The recommended amount of GCTB is at least 5.50 Mg ha-1, taking into account soil health and the need for biofuel generation.

“…Dalam industri pertanian peranan air sebagai sumber daya alamiah yang sangat penting. Produktivitas tebu yang rendah di Brazil disebabkan oleh curah hujan yang rendah dan sistem irigasi yang belum efektif (Gonçalves et al, 2019). Di Cina, keterbatasan sumber daya air menjadi salah satu kendala signifikan untuk mengembangkan pertanian berkelanjutan dan dalam meningkatkan produktivitas (He et al, 2021).…”

“…Pemanfaatan vinase sebagai residu dari produksi mendorong peningkatan kualitas unsur hara pada tanah, sehingga dapat mendorong peningkatan kualitas tanaman tebu. Penelitian lain di Brazil, melakukan penerapan pengolahan air limbah seperti treated domestic sewage (TDS) untuk dijadikan sumber air dan nutrisi alternatif untuk budidaya tebu (Gonçalves et al, 2019).…”

Indonesia memiliki potensi mengembangkan industri gula berkelanjutan. Dalam menuju industri berkelanjutan dibutuhkan tata kelola dalam industri gula sehingga dapat mendorong produktivitas dan meningkatkan daya saing tinggi serta mendukung keberlanjutan lingkungan. Tujuan dari penelitian ini adalah mengulas dan membandingkan tata kelola industri gula antara Brazil dan Indonesia, sehingga dapat menghasilkan rekomendasi yang tepat dalam tata kelola Industri gula. Pendekatan penelitian ini dilakukan dengan metode kualitatif dengan studi literatur penelitian di Brazil dan literatur lainnya. Industri gula di Brazil berkembang melalui penetapan kebijakan melalui undang-undang Renovabio dalam mengembangkan biofuel. Pemerintah Brazil memberikan insentif untuk mendorong pelaku industri gula di Brazil dalam menerapkan industri gula berkelanjutan. Hal tersebut bertujuan untuk mengurangi efek gas rumah kaca (GRK). Hal tersebut mendorong industri gula di Brazil memiliki produktivitas dan daya saing tinggi secara global. Produktivitas Industri gula di Indonesia dibandingkan Brazil sangat rendah. Pada periode tahun 2010 hingga 2020, hasil produksi gula di Indonesia hanya sekitar 5 ton per hektar dengan rata-rata yield 68,85-ton tebu per hektar. Sedangkan, yield perkebunan tebu di Brazil rata-rata di atas 70 ton per hektar. Dalam tata kelola, Brazil juga menggunakan teknologi pertanian pada industri hulu, dan didukung dengan kebijakan energi terbarukan tersebut.
