Yield and nutrient uptake by sweet corn as influenced by sowing dates and plant spacing under lateritic soils of Konkan

An experiment was conducted during rabi seasons of 2007–08 and 2008–09 to find out the effect of sowing dates and plant spacings on yield and nutrient uptake of sweet corn at Dapoli (Ratnagiri) on sandy clay loam soils of south Konkan coastal zone of Maharashtra, which revealed that winter sweet corn sown in 45^th meteorological week (5–11 November) gave maximum mean cob yield of 199.75 q ha⁻¹ with maximum values of nutrient uptake and net returns than the subsequent delayed sowing. The plant spacing of 60 cm x 20 cm (83, 333 plants ha⁻¹) resulted in higher nutrient uptake over wider spacing of 60 cm x 40 cm (41, 666 plants ha⁻¹ a) and 60 cm x 20 cm (27, 777 plants ha⁻¹).
