The current low incidence of sugarcane diseases in the South African sugar industry has been hardwon. This achievement is due largely to the selection and release of resistant varieties. Consequently, current estimates of crop loss due to smut and mosaic indicate reductions in yield of only 0.2% in total, equivalent to R7 million per annum. In the absence of an RSD variety resistance screening ...

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...

The incorporation of ecological practices into sugarcane production and management has the potential to arrest and ameliorate the negative effects of monocropping on soil degradation and yield decline. Historically, the production of green manures as cover or break crops has been shown to improve the physical, chemical, and biological properties of soil for many crops in production agriculture....

This paper presents a method for crop yield forecast based on remote sensing and official data. The method uses a statistical approach to extract different pixels of smoothed NDVI data derived from MODIS sensor to be used as proxies for sugarcane yield estimation at a municipal scale. From 368 municipalities with yield's historical data from 2003 to 2012, three groups were created based on acre...

Information on variations in crop yield among farmer fields in a specific area and theircausal factors is important for efficiently targeting efforts to increase production of the crop inthe target area. This study determined the yield variations and their causal factors for sugarcanegrown in the service area of a sugar mill in Northeast Thailand. Two villages with the dominantsandy and clayey ...

Commercial sugarcane records for 19 seasons from 146 fields were obtained from five estates in the KwaZulu-Natal Midlands. Extensive editing and cleaning of the agronomic records was required. Regression models were developed, and depending on the predictor variables selected, the best model accounted for 55% of the observed yield variation, based on 535 crop cycles. The final models were valid...

Sugarcane and agave bagasse samples were hydrolyzed with either mineral acids (HCl), commercial glucanases or a combined treatment consisting of alkaline delignification followed by enzymatic hydrolysis. Acid hydrolysis of sugar cane bagasse yielded a higher level of reducing sugars (37.21% for depithed bagasse and 35.37% for pith bagasse), when compared to metzal or metzontete (agave pinecone ...

abstract soil compaction is a main factor that reduces the cane yield in sugarcane fields, in southwest of iran, especially in ratoon cropping system. therefore, sub-soiling practices could alleviate adverse effects of compaction and increased yield. in according to this aim, a study was to evaluate the effect of  ratooning practice systems consisting of control (no subsoiler), two and four sha...
