Effect of three biostimulants on reducing herbicide damage in sugarcane cultivation
Last Updated: junio 11, 2025Herbicide damage in sugarcane crops can cause leaf chlorosis, leaf necrosis and, in some cases, retardation of crop growth and decreased sugarcane yield. We evaluated the effect of three biostimulants (T1: hormone mobilizer + micronutrients, T2: amino acids + gibberellic acid (GA) + micronutrients, T3: algae + GA + micronutrients, T0: control with no biostimulants) in combination with the conventional herbicide formula (diuron 1600 g ai ha⁻¹, ametryn 1000 g ai ha⁻¹, amine 1080 g ai ha⁻¹, mesotrione 144 g ai ha⁻¹ and terbutryn 500 g ai ha⁻¹).
Effect of trinexapac-ethyl on seedcane quality to improve stand establishment in sugarcane
Last Updated: junio 11, 2025Most of the sugarcane in Florida is planted manually, but with increased labor shortages, sugarcane growers are exploring the possibilities of using mechanical planters such as billet planters to plant cane in Florida. However, the increased use of machines in the handling of seedcane imposes the risk of mechanical damage to the buds and the seedcane, which leads to the occurrence of skips and gaps resulting in poor germination and crop establishment, thus forcing growers to plant at higher densities to compensate for the losses. This study aimed at increasing the number of buds per unit billet length by reducing the internode length.
Effect of urea fertilization timing and application rates on quantitative and qualitative traits of sugarcane variety CP69-1062
Last Updated: junio 11, 2025Urea, as a common N source, is widely used in sugarcane cultivation. However, the timing and amount of urea fertilization can significantly impact the quantitative and qualitative traits of sugarcane. Optimizing these two factors can lead to increased yield, improved product quality, and reduced production costs.
Effects of replanting and the use of an absorbent polymer on sugarcane productivity
Last Updated: junio 11, 2025Where there are failures in germination, sugarcane seedlings are an alternative for replanting. Hydrogels are polymers that absorb and release water without dissolving. This work evaluated the effects of replanting with seedlings and the contribution of application of an absorbent polymer on sugarcane productivity .
Efficacy of biostimulants on sugarcane growth and yield under saline-sodic conditions in Zimbabwe
Last Updated: junio 11, 2025Biostimulants enhance nutrition efficiency, abiotic stress tolerance, and crop quality. The study evaluated biostimulants under saline-sodic conditions to improve yields and help plants tolerate stress. Two saline-sodic study sites in Zimbabwe with pH ranging from 7.14 - 8.34, and sodium adsorption ratio (SAR) ranging from 8 - 15.1 were selected.
Efficacy of using calcium and magnesium oxides of different granularities in ratoon sugarcane
Last Updated: junio 11, 2025Brazilian soils where sugarcane is cultivated are typically acidic and have low calcium content at depth, which limits the productivity of sugarcane, particularly in ratoons. Limestone, the primary source used to raise pH levels, has low solubility and limited effectiveness when applied to the soil surface over the straw/trash layer.
Evaluation of energycane for biomass accumulation and its ecosystem services on fallow sandy soils
Last Updated: junio 11, 2025Lignocellulosic energy crops, such as energycane (sugarcane with higher fiber and lower sugar content), have the potential to supply one-third of the biomass required for the U.S. bioeconomy by 2030. Evaluating cost-effective, regionally tailored agronomic practices is crucial, especially considering the high yields of energycane on fallow croplands.
Evaluation of water quality for irrigation in sugarcane
Last Updated: junio 11, 2025In Colombia’s Cauca River valley, sugarcane is mainly grown in dry to semi-dry environment, making irrigation necessary to avoid water stress that reduces crop productivity. This study evaluated the effects of four different sources of water for irrigation (river water, well water, non-treated water from wastewater treatment plants (WWTPs) and treated water from WWTPs) on sugarcane productivity and the concentration of nutrients and heavy metals in both the soil and the crop.
Fertilization Advisory System (SEF 3.0) by Cenicaña: a holistic tool for efficient management of fertilizers
Last Updated: junio 11, 2025Soil fertilization is the most significant cost in sugarcane cultivation in Colombia. Current fertilization plans typically rely on sufficiency criteria, neglecting factors such as variety-specific nutrient uptake, field productivity potential, and soil bulk density. Furthermore, fertilizer sources are often selected empirically, without considering their interactions with soil pH, texture, or environmental conditions.

Foliar application of boron and molybdenum on growth and sucrose accumulation in sugarcane variety CC 05-430 in the Cauca River Valley, Colombia
Last Updated: junio 11, 2025The impact of foliar-applied boron and molybdenum on the growth, development, and sucrose accumulation of sugarcane variety CC 05-430 was evaluated. The experiment was arranged as a randomized complete-block design with two treatments and five replicates of boron (560 and 700 g ha⁻¹) in combination with molybdenum (8 and 10 g ha⁻¹) applied 210 days after the previous harvest.
