Organic manure, phosphate and potassium fertilization in relation to growth, productivity and quality of sugarcane

Abstract EN

The present study was carried out at the private farm, Kom-Ombo-Aswan, Upper Egypt, during the two growth seasons of 2017/2018 and 2018/2019 to study the effect of organic, phosphate and potash fertilization on productivity and quality of sugarcane plant crop (Commercial variety, Giza Taiwan = C 9).

The experimental design of this study was a split- split plot design in three replicates for both seasons.

Three levels of organic manure (10, 20 and 30 m 3 /fed) were randomly assigned in the main plots, three phosphate fertilizer levels (100, 200 and 300 kg of mono super calcium phosphate/fed) were allocated in the sub plots and three potash fertilizer levels (50, 100 and 150 kg in the form of potassium sulphate/fed) were randomly distribution in the sub- sub plots.

Net plot size was 4.5 m x 8.0 m in 75 cm spaced trenches.

The results revealed that increasing organic manure from 10 to 30 m3 /fed increased productivity of sugarcane.

Moreover, increasing the rate of phosphate fertilizer up to 200 kg and potassium sulfate up to 150 kg/fed recorded the highest yield of sugar cane in both seasons under this study.
