Response of Bt Cotton hybrid to plant densities and fertilizer levels

Field experiment was conducted with an object to find out suitable plant density and fertilizer level to Bt cotton hybrids under rainfed conditions of Khandwa during 2008-09 and 2009-10 at Cotton Research Center, Khandwa, Agriculture University Gwalior. Results clearly indicated that higher plant density i.e., 27777 plants/ha (60×60 cm plants spacing) performed better than lower plant densities (18518 and 12345 plants/ha), respectively proved beneficial than lower level (80:40:40 and 60:30:30 NPK kg/ha). Among the Bt hybrids NSPL-999 performed better than RCH-2 with a 42.45 per cent higher seed cotton yield.
