“…In December before the sugarcane first ratoon has been harvested, crop water requirements were zero, because this month in this study was a dry-off period of the sugarcane first ratoon to improve sugarcane quality. [21] found that sugarcane needs supplemental irrigation of 508.8 mm/season to cane plant and 486.5 mm/season to ratoon cane with a higher frequency of irrigation in the development phase II.…”

“…The reduced competition of sugarcane for nutrients, moisture and light might have helped in profuse tiller production and low shoot mortality resulting in realizing a higher number of millable canes [32]. [21] reported that water stress restricted photosynthesis, elongation and lateral enlargement. [33] were observed that the furrow method, when irrigation was applied at longer intervals.…”

Aims: This study aimed to evaluate the effect of deficit irrigation at different growth periods on the yield and quality of sugarcane (Saccharum spp.) first ratoon. Study Design: The study was carried out in Randomized Complete Block Design (RCBD), with three replications. Place and Duration of Study: A field experiment was conducted during two seasons, 2020-21 and 2021-22 at Guneid Sugarcane Research Center Farm, Sudan. Methodology: Irrigation deficit treatments were applied when available soil moisture content (ASMC) reached 25% in the root zone at eight different growth periods viz; DT1: first day to day 50th, DT2: day (5th - 100th), DT3: day (10th -150th), DT4: day (15th - 200th), DT5: day (20th - 250th), DT6: day (25th - 300th), DT7: day (30th - 350th) and DT8: day 35th to day 400th after ratoon establishment. These were compared with optimum irrigation (DT0) which was irrigated at 60% ASMC at the root zone. Results: The results showed that all deficit irrigation treatments (DT1 to DT8) recorded significant cane and sugar yield reduction to the control (DT0) in the two growing seasons. In this sense, DT3, DT4 and DT5 treatments have recorded the highest cane and sugar yield reduction. Moreover, irrigation deficit affected negatively the sugarcane ratoon yield parameters with low cane water productivity in DT4 and DT5 treatments. Therefore, sugarcane first ratoon must be avoided to deficit irrigation at age of 3.3 months to 10.0 months. Conclusion: According to the results sugarcane first ratoon (Variety Co 6806) established in December under the Central Sudan Agro-climatic zone (Gunied conditions) must be avoided to deficit irrigation at ratoon age of 3.3th month to age 10.0th month (at ratoon age 100 days to 300 days), because of high reduction on cane yield and sugar yield and low in water productivity.

Brazil is the largest producer of sugarcane (Saccharum spp.) in the world, and this crop’s response to climate and soil water storage is essential for optimal management and genetic/yield improvements. The objective of our study was to build a multivariate model to estimate sugarcane yield in the subtropical conditions of the northwestern Paraná region using climatic and soil water storage variables. Observed yield data was used from experiments conducted at the Experimental Station of the Sugarcane Genetic Improvement Program of the Universidade Federal do Paraná. The sugarcane varieties RB72454, RB867515, RB966928, and RB036066 were analyzed in the 1998–2006, 2008, 2018 and 2019 harvest years. Stepwise multiple linear regression analysis with repeated cross-validation was developed to estimate sugarcane yield given climate and soil water storage variables for crop growth phases. The accumulated degree days in Phases I and II and soil water storage in Phase II of development significantly impacted sugarcane yield. The multiple linear regression model, with accumulated degree days and soil water storage in Phases I and II of development, successfully predicted sugarcane yield for analyzed varieties. Sugarcane production models like the one we developed can improve crop management for greater sustainability and climate change adaption in Brazil and other areas.
