THE PRESENT investigation was carried out at Shandaweel Agricultural Research Station, Sohag Governorate (latitude of 26°33'N, longitude of 31°41'E and Altitude of 69m), in the two successive seasons 2016/2017 and 2017/2018 to investigate the effect of study the effect of nitrogen, phosphorus and filter cake on yield and quality of sugarcane. The filed experimental work was carried out in a Randomized Complete Blocks Design (RCBD) using a split-split plot arrangement in three replications in both growing seasons.
The results showed that increasing nitrogen levels from 150 up to 210kg N/fad resulted in a significant increase in plant length, diameter, stalk weight, number of millable canes, cane and sugar yields, as well as brix, sucrose, quality and sugar recovery percentages in both seasons.
Super phosphate addition by rates 30kg P2O5/fad resulted in a significant increase in plant length, diameter, number of millable canes, stalk weight and cane and sugar yields, as well as brix, sucrose and sugar recovery percentages in both seasons.
Results showed that the addition of filter cake by 4tons/fad give a significant increase in plant length, diameter, number of millable canes, stalk weight, cane and sugar yields, as well as brix, sucrose and sugar recovery percentages in both seasons.
