Abstract

A field experiment was conducted at Agricultural Research Station, Kathalagere during kharif,
2007 on clay loam soil under rainfed conditions to study the influence of nitrogen and harvesting
stages on dry matter accumulation and leaf, stem, ear head, total dry matter accumulation and
biomass yield of sweet sorghum genotypes. Dry matter accumulation (DMA) in leaf, stem, ear head,
total dry matter accumulation (TDMA) and millable cane yield were significantly influenced due to
genotypes, N-levels and stages of harvesting. SSV-84 recorded significantly higher DMA in leaf (46.20
g), stem (373.5), ear head (74.3 g), TDMA (496.6 g plant -1) and the green bio mass yield (42.78 t ha-
1). Application of 125 per cent N-dose (81.25 kg ha-1) recorded the higher TDMA (469 g plant -1) in
sweet sorghum. It also recorded the higher millable cane yield (43.0 t ha-1).Among the harvesting
stages tried physiological maturity stage recorded significantly higher TDMA (485.3 g plant -1) and
millable cane yield(45.36 t ha-1)
