Description A field experiment was conducted at Main Agricultural Research Station,
University of Agricultural Sciences, Dharwad in Northern Transition Zone (Zone 8)
of Karnataka on clay soil to study the response of multicut fodder sorghum (CoFS-29)
to row spacings and nitrogen levels under irrigated condition during 2010-11. The
experiment was laid out in RCBD with factorial concept, there were 12 treatment
combinations consisting of three row spacings (30, 45 and 60 cm) and four
levels of nitrogen (120, 180, 240 and 300 kg ha-1). Nitrogen at all levels is divided into
six equal parts at sowing, 30 days after sowing and after each cutting four times.
Phosphorus 40 and potassium 40 kg ha-1 were applied at the time of sowing. The crop
was harvested for green forage at 50 per cent flowering in each treatment at all the
cuttings.
The row spacing of 45 and 60 cm recorded significantly higher total green
fodder (153.9 and 149.2 t ha-1, respectively) and total dry matter yield (36.28 and
35.18 t ha-1, respectively) compared to 30 cm row spacing. Application of 300 kg N
ha-1 recorded significantly higher total green fodder yield (179.63 t ha-1) and total dry
matter yield (42.33 t ha-1) compared to lower levels. Higher level of nitrogen
improved the quality of fodder.
Higher total green fodder yield (187.58 and 183.30 t ha-1), total dry matter
yield (44.2 and 43.2 t ha-1), net returns (Rs. 82763 and 80199 ha-1), benefit cost ratio
(3.78 and 3.69) and better quality parameters were observed with 45 and 60 cm row
spacing, respectively with 300 kg N ha-1.
