N1  - We thank Drs Ashok Kumar, Ravinder Reddy and P. Srinivas Rao, Sorghum Breeding, ICRISAT for their help and providing the seeds of different cultivars for sweet sorghum trials. We also thank financial support by the NAIP?ICAR for conducting the research as a part of NAIP?ICAR?Sweet sorghum bioethanol project. This article is part of a special edition on Soil and Water Management (Volume 110, Issue - 09, May 10, 2016)
N2  - Sweet sorghum (Sorghum bicolor (L.) Moench) is a
smart biofuel crop, which can be grown under tropical
rainfed conditions without sacrificing food and fodder
security. Three sweet sorghum cultivars (viz. ICSA
52 ? SPV 1411, CSH 22 SS and ICSV 93046) were
grown under six nitrogen levels (0, 30, 60, 90, 120,
150 kg ha?1) on Vertisols during two rainy (kharif)
seasons at ICRISAT, Patancheru, India. The results
from two-year trial indicated that out of three sweet
sorghum cultivars evaluated, sweet sorghum hybrid
CSH 22 SS produced highest green stalk (46.90 t ha?1)
and ethanol yield (1940 l ha?1) compared to other cultivars.
The three cultivars responded well to applied N
doses up to 150 kg ha?1, however, application of N beyond
90 kg ha?1 did not result in any significant increase
in grain yield and economic returns. Net
economic returns of Rs 32,898 ha?1 (US$ 601.21 ha?1)
were significantly higher with 90 kg N ha?1 application
as compared to other levels of fertilization. It is concluded
that for obtaining the highest green stalk yield,
ethanol yield and thereby maximum economic
returns, sweet sorghum cultivar, viz. CSH 22 SS
should be fertilized with 90 kg N ha?1.
