The role of ratoon stunting disease in causing yield losses under fully irrigated conditions in the lowveld is as yet undefined. Hot water treatment at 50:5OC for 2 hr was shown to adversely affect germination and reduce stalk population in certain varieties. The optimum age for hot water treatment of NCo 310 and NCo 376 seedcane was found to be 11-12 months. Exposure of hot water treated cane ...

abstract this study was carried out in farm of dehkhoda institute (2013-2014). the study was done as randomized complete blocks design with five potassium sulfate amounts (0, 50, 100, 150 and 200 kg/ha) and four replications. according to results, potassium affected the number of stalk numbers, yield, and the amount of obtainable sugar (p<0.01) and purity (p<0.05). the highest stalk numbers (18...

The South African Sugar Association Experiment Station, Agricultural Engineering Department conducted a series of semi-mechanised versus fully mechanised harvesting trials on a large commercial estate in Swaziland over the 1998/1999, 2000/2001 and 2001/2002 seasons. During the trials machinery performance was measured, differences in the quality of cane delivered to the factory were determined,...

The Ord River Irrigation Area is 3200 km NE of Perth on latitude 15 30’ S, at an altitude of less than 100 m, with rainfall of 800 mm. Water is supplied from the vast Lake Argyle, soils utilised for agriculture are predominantly black montmorillonitic clays and topography is generally very flat. Growing conditions are superb for most tropical crops. Out of a total of 11000 ha under irrigation, ...

In this study, the effects of nitrogen fertilizer and plant growth regulator (ethephon) application on leaf chlorophyl, stem height and diameter, stalk yield, total sugar and bioethanol of sweet sorghum were determined. Four nitrogen treatments 0, 100, 200 and 300 Kg Urea ha-1 and four ethephon concentrations 0, 800, 1000, and 1200 ppm were applied on sweet sorghum in a split plot on randomized...
