Abstract
Two field experiments were carried out at the Agricultural Experimental and Research Station, Faculty of Agriculture. Cairo University, Giza, Egypt. dunng 2003 and 2004 seasons to study the effect of some nitrogen rates ( 0, 40, 80, and 120 kg N/fed) and between hill spacing ( 20, 25. and 30 cm ) on yield and juice quality of sweet sorghum. Variety ., Roma" was used in the study. Increasing nitrogen rates from zero to 120 kg N/ied m~dl ~eaiy increased stalk diameter. stalk length and reducing sugars. while Brix and sucrose were decreased with increasinq nitrogen rate. Stalk weight. juice extraction. and stripped stalk yield as well as syrup yield (galion/fed) and total juice sugar yield were increased as nitrogen rate was increased up to 120 kg N/fed. The results also revealed that the wider space (30 ern) between hills produced the highest stalk diameter. stalk length. Brix. and sucrose as well as reducing sugars and purity percentages. On the other hand stalk weight, stripped stalk yield. syrup yield gallon/led and totat juice sugar yield were increased With sweet sorghum grown al 25 em between hills. The interaction between nitrogen rate and hili spacing had a significant effect on some studied traits. Sweet sorghum grown at 25 cm between hills and given 120 kg N/fed gave the highest stopped stalk yield (ton/fed). syrup yietd (galton/fed) and total juice sugar yield (tonlfed)
