A simple economic sensitivity analysis of nitrogen application rates: a case study using ratoon trials under irrigated and rainfed conditions in South Africa
Last Updated: junio 11, 2025Current fertiliser nitrogen (N) recommendations aim to provide near maximum yields, rather than optimal revenue returns. However, recent surges in fertiliser prices resulted in many growers seeking short-term advice on reducing N-rates without compromising profitability.
Agroclimatic zoning of sugarcane areas in Cuba
Last Updated: junio 11, 2025Sugarcane is a fundamental C4 crop in many regions of the world, valued not only for its economic contribution but also for its significance in biofuel production and other derivatives. This crop encounters considerable challenges stemming from climate variability, which adversely impacts both its productivity and yield.
Agronomic interventionsinsub-tropicalIndia for sustainablesugarcane cultivation and farmer empowerment
Last Updated: junio 11, 2025The decline in cane yield and sugar content in the subtropical regions of India is an issue of concern for sugarcane growers and the industry alike. This prompted a detailed study on the impact of different sustainable practices on sugarcane cultivation, yielding a list of steps to optimize yield and ensure farmer empowerment.
Analysis of the diversity and abundance of weeds in sugarcane crops
Last Updated: junio 11, 2025Weeds present a significant challenge to agricultural production, particularly in extensive crops like sugarcane. Effective weed management requires sampling methods that yield representative data on weed abundance and distribution. This study compares two sampling methods, diagonal and zigzag, based on population variables of diversity and abundance of weeds in sugarcane fields, using functional groups to classify species.
Apparent nitrogen recovery of exogenous sources of organic matter in tropical soils: update and new coefficients to improve fertilisation in sugarcane
Last Updated: junio 11, 2025Sugarcane is an economic pillar of Réunion, and improving the productivity of the 20 000 ha of sugarcane is a major challenge for this community. Optimising the fertilisation practices is a way to improve this productivity. However, the farming sector is dependent of imported mineral fertilisers, and recent price increases and availability issues question this dependence.
Benefits of Vicia villosa in intercropping with sugarcane: analysis of spatial arrangement and yield
Last Updated: junio 11, 2025Sugarcane monocropping leads to soil degradation over time, compromising ecosystem services. This work aimed to design an intercropping system of vetch (Vicia villosa-Rizhobium) and sugarcane and assess its yield benefits in comparison to monocropping. Three field experiments were conducted in a dry-subhumid depressed plain in a typical Haplustoll soil.
Calcium dynamics in sugarcane soils with high magnesium saturation in the northern Cauca River Valley
Last Updated: junio 11, 2025In the Cauca River Valley, about 117,000 ha are affected by excess magnesium in the soil. Traditional management has followed a principle similar to sodium management: increase calcium levels. To study calcium dynamics in soils with high magnesium saturation dedicated to sugarcane production located in the northern part of Cauca Valley, three experiments were established at the Ingenio Risaralda, two of them in the field (plant cane and ratoon) under a randomized complete block experimental design (RCBD), and one under controlled conditions (containers) in a completely randomized design (CRD).
Characterization of the soil degradation factors in areas planted with sugarcane in Cuba
Last Updated: junio 11, 2025The objective of this study was to use soil groups to characterize the main soil degradation factors that limit the production of sugarcane in Cuba. The most representative soil group was selected for each province, grouping them on similar formation processes, physicochemical characteristics and soil limitations.
Drought stress ‘memory’ increases cane yield and juice quality of field-grown sugarcane
Last Updated: junio 11, 2025This study explored the impact of intergenerational drought ‘memory’ on sugarcane yield and quality. Two sugarcane cultivars IACCTC07-8008 (drought tolerant) and IACSP95-5000 (high yielding) were subjected to drought cycles during tillering (group T) or maturation stage (group M).

Early-season fall panicum (Panicum dichotomiflorum) control and sugarcane tolerance to a premix of atrazine, mesotrione and S-metolachlor
Last Updated: junio 11, 2025Field studies were conducted in 2014-2015 and 2015-2016 to determine preemergence (PRE) and early postemergence (POST) control of fall panicum in sugarcane with the premix of atrazine, mesotrione, and S-metolachlor on organic and mineral soils of Florida, and to determine the response of sugarcane varieties to PRE and early POST application of the premix.
