Description
In 2 field experiments conducted at Agricultural Research Station, Tamil Nadu Agricultural University Farm, Bhavanisagar in red loamy soil (Typic Ustropept), the recovery of added 15N-urea was monitored under groundnut-sorghum cropping sequence. Fertilizer 15N was applied as urea at 5, 10 and 15 kg N/ha levels. The highest pod yield (2.18 t/ha) and haulm yield (13.19 t/ha) were recorded at 10 kg N ha-1 level. Out of 10 kg N applied, 51.86 per cent was recovered by the first crop of groundnut and found distributed as 43.13, 1.70 and 8.03 per cent in haulm, shell and kernel, respectively. The residual N recorded by the second crop of sorghum was only 0.63 per cent. (author). 4 refs., 4 tabs
