ABSTRACT
An experiment was conducted during rabi seasons of 2007-08 and 2008-09 to find out effect of sowing dates and plant spacing on growth and yield of sweet corn at Dapoli Dist. Ratnagiri, on sandy clay loam soils of south Konkan coastal zone of Maharashtra. A two years field study revealed that winter sweet corn sown in 45th meteorological week (5 Nov.-11Nov.) gave maximum cob yield of 199.75 q ha-1 with maximum values of growth and yield attributes than the delayed sowing from 51st to 3rd meteorological week. The plant spacing of 60 x 20 cm (83,333 plants/ha) produced 208.45 q ha-1 over the wider spacings of 60 x 40 cm (41,666 plants/ha) and 60 x 20 cm (27,777 plants/ha). It seems therefore, that more yields would accrue to the farmers if winter sweet corn is grown to the spacing of 60 x 20 cm under adequate resources and the productivity of winter sweet corn can be improved simply by manipulating the plant density.
Key words :
Plant spacing, sowing time, winter sweet corn, yield attributes.
