Abstract
Effects of the application of 20-80 kg N/ha by 3 methods on N uptake in 3 kharif [summer monsoon] crops maize, sorghum and bajra [Pennisetum americanum] and 4 rabi [winter] crops wheat, barley, sarson [Brassica napus var. glauca] and oilseed flax on sandy loam soil under rain-fed conditions at Delhi were determined. The total N uptake in kharif crops increased with increasing N levels. N uptake in barley and sarson was highest with 80 and 60 kg N/ha, respectively; it was highest in oilseed flax with 20 kg N/ha. N uptake was higher with N placed 10 cm deep in the soil or when 50% N was placed in soil and the remainder applied as a foliar spray than when applied broadcast. The N utilization efficiency was highest in bajra, followed by maize, oilseed flax, sorghum, sarson, barley and wheat. The utilization of soil N was highest in sarson and bajra
