    Abstract

    The sweet sorghum variety, ICSV 93046 is commercially cultivated in large areas in India and the Philippines. The response of ICSV 93046 to six fertilizer treatments viz., T1 (control: 80 kg N ha−1 and 40 kg P2O5 ha−1); T2 (designed fertilizer from a commercial source); T3 (N + P with Zn and B soil application); T4 (N + P with Zn and B soil application); T5 (N + P with foliar application of 0.1 % sodium borate and T6 (N + P with foliar application of 0.5 % ZnSO4 and 0.1 % sodium borate) was evaluated during the post-rainy season (December–March, 2009–2010) as main (plant) crop and during summer season (April–July, 2010) as ratoon crop. The combined ANOVA showed that there were no significant differences observed between main and ratoon crops and the treatment interactions for the qualitative and quantitative component traits of sugar yield measured and also no significant differences observed for main and ratoon crop except for non-significant numerical differences giving a trend. The stalk yield was highest for treatments T5 and T6 in main crop and in the ratoon crop however, the treatment T4 recorded the highest stalk yield.
