Abstract: Egyptian grower is usually adding farmyard manure to the soil during the soil preparation for growing plant cane .So,two field trials were conducted at Malawi Agric. Res., Station, Minia Governorate, Egypt, during 2007/2008 and 2008/2009 seasons to determine the effect of different levels of potassium, nitrogen and farmyard manure fertilizers on yield and quality characteristics of sugar cane . Two levels of potassium ,i.e. 0.00 and 48 kg K2O/fed , three levels of nitrogen ,i.e. 160, 200 , 240 kg /fed, and three levels of farmyard manure (10 , 15 and 20 m3/fed) were studied a split-split plot design and G.T. 54-9 cultivar was sown.
The data recorded pointed out that potassium, nitrogen and farmyard manure fertilizers levels exhibited a significant effects on millable cane and recoverable sugar yields (ton/ fed)of sugar cane as well as N and K concentrations in TVD plant tissues in the two growing seasons . K-fertilizer levels had a significant effects on quality characteristics, i.e. TSS%, purity% , pol % and sugar recovery % in the 1st only.However, N-fertilizer levels had a significant effects on quality characteristics, i.e. TSS%, purity% , pol % and sugar recovery % in the 2nd only.While farmyard manure levels exhibited a significant effects on quality characteristics, i.e. TSS%, purity% , pol % and sugar recovery % in the two growing seasons.
Therefore, the maximum values of millable cane and recoverable sugar yields of sugar cane were obtained with applying 48 kgK2O/fed,200 kg N /fed and 20 m3/fed of farmyard manure is preferable because it gave the highest values of millable cane yield (59.05 and 51.21 ton/fed)and recoverable sugar yield (7.97 and 6.76 ton/fed) in the two growing seasons , respectively.
