Nutrient Partitioning and Stoichiometry in Unburnt Sugarcane Ratoon at Varying Yield Levels

Unraveling nutrient imbalances in contemporary agriculture is a research priority to improve whenever possible yield and nutrient use efficiency in sugarcane (Saccharum spp.) systems while minimizing the costs of cultivation (e.g., use of fertilizers) and environmental concerns. The main goal of this study was therefore to investigate biomass and nutrient [nitrogen (N), phosphorus (P), and pota...

Spatial Variability Analysis of Soil Physical Properties of Alluvial Soils

ited on sandy or on loamy sediments. Therefore, it is important to study not only the extent of surface spatial Analysis and interpretation of spatial variability of soils is a keyvariability, but also the distribution of subsurface and stone in site-specific farming. Soil survey maps may have up to 0.41ha inclusions of dissimilar soils within a mapping unit. The objectives deep soil horizons. ...

Effect of Ratoon Stunting Disease on the Yield and Components of Yield of Sugarcane under Rainfed Conditions

In a field trial conducted with eight varieties in the north coast area of Natal ratoon stunting disease (RSD) caused increasing lossesin yieldsof cane and sucrosefrom the plant to the second ratoon crop. All the varieties suffered losses in yield but the degree of loss differed markedly among the varieties. The total yield of sugar from the three crops was reduced by 38% in varieties NCo 376an...

Effect of the Dithiocarbamate Fungicide Mancozeb on Sugarcane Growth and Soil Biology in Yield Decline Affected Soils

The dithiocarbamate fungicide mancozeb is used extensively around the world for control of foliar diseases. Initial yield decline research in the early 1990s investigated soil application of fungicides for the amelioration of poor root health in sugarcane. Experiments in both the glasshouse and field have since shown that root health and plant growth improve dramatically following mancozeb appl...
