Abstract

Two field experiments were carried out at the Research Experimental Farm of Sabahia, Agricultural Research Station, Alexandria during the two successive growing seasons of 2011/ 12 and 2012/ 13. G2006-77 sugarcane variety (Saccharum officinarum L.) was cultivated to investigate the effect of two planting dates, October (autumn planting) and in March (spring planting), three soil  ploughing treatments (two, three and four passes). and two distances between hills (100 and 125 cm.) on sugarcane yield and its components. The results indicated that planting date did not affect the stalk diameter, stalk yieldand sugar yields but it significantly increased stalk length with spring planting. Four soil ploughings is fair enough for producing higher stalk length and sugar yield No-significant differences between values of stalk diameter and stalk yield affected by different soil  ploughing numbers  from 2, 3 and 4 in  the 1st and 2nd seasons. No significant effect were found in stalk diameter, stalk yield  and sugar yield  during the two seasons by planting at (100 and 125 cm.) between hills.The interaction among planting date soil ploughing and distances between hills were significant with respect to stalk diameter, stalk yieldand sugar yields during both successive seasons.
The planting dates had no significant effect during the        1 st and 2nd seasons on T.S.S. % and purity %. However there was significant effect during the two seasons on sucrose %. The highest values of sucrose % (15.60and 15.64%) were obtained as a result  of spring planting in both seasons, respectively.
Significant differences in T.S.S. %, sucrose % and purity % by number of ploughing were found in the two consecutive seasons.
T.S.S. % the1 st season and sucrose % in the 1st and 2nd seasons were significantly different decreased with the distances between hills, No significant effect was found in purity % during the two seasons and T.S.S. % the 2nd season by planting at (100 and 125 cm.) between hills. Generally, as a conclusion and on the basis of the obtained results that planting G2006-77 sugarcane variety in spring planting season, 4 ploughings and  125 cm between hills produced the highest values of stalk length(cm.), stalk diameter (cm.), stalk yield (ton/ fed)  and sugar yields(ton/ fed )  as well as T.S.S.%,  sucrose% and purity % under Alexandria conditions
