Field trials were used to investigate the phytotoxicity of foliar sprays of 2,4-D amine to sugarcane. Yield losses of variety NCo 376 resulted from band sprays when 3,3 kg ae/ha was sprayed onto plant or ratoon cane which had unfurled three or more leaves per shoot. The greater the foliar development of the crop at the time of spraying, the greater was the resulting crop loss. At similar stages...

ABSTRACT Conservation management practices with minimum soil mobilization, maintenance of amounts straw in the soil, and chiseling ratoons interrows can be beneficial to quality, nutrition sugarcane yield; however, combination these their influence over culture cycle should better understood. This study aimed assess effects levels remaining cultivation on fertility, nutritional status yield sta...

Full retention of sugarcane (interspecifi c hybrids of Saccharum spp.) postharvest residue may reduce ratoon crop yields. The objective of this study was to determine the effects of different residue removal timings and methods on sugarcane yield. A two-factor (timing and method) experiment was conducted on both clay and silt loam soils in southeastern Louisiana. Removal timings consisted of th...

The top visible dewlap leaf potassium (K) of sugarcane ratoons varies in an irregular manner with age ofcane. However, by increasing the number of leaf samplings, the fluctuation of the mean K values with age becomes less and less significant. As a result in Mauritius, where the running average leaf K concentration of 3 consecutive years of double leaf sampling is interpreted, age corrections o...

The yield of ratoon rice technology has the potential to match production main crop or first crop. As a result continuous chemical fertilization, paddy soil becomes acidic. This study aims obtain information on effectiveness neutralizing pH and fertilizing nutrients N, P, K in increasing rice. design used was randomized block with one factor, namely there were 7 types fertilization treatment fo...

Sugarcane mechanized harvesting can lead to serious risks the longevity of plantations when improperly operated, and may cause damages disturbances in remaining ratoons field. In this sense, study aimed evaluate damage disturbance sugarcane by base cutting quality two-blade models through statistical process control. The experiment was carried out during 2015/16 growing season an agricultural a...
