The efficiency of Uroa-N applied in uneven-splits and in briquette form to maize crop was studied in Khari! 1978 and 1979 and in rabi 1979-80. Application of 70 to 120 Kg. N/ha encouraged the days to silking by 5 to 7 days, Ures briquettes were not found so effective in the case of maize, Application of 10 Kg N/ha initially or after 45 days was not sufficient. In 110 Kg N/ha in 30-50-30 splits, and in rabi, 120 Kg N/ha in 40-40-40 splits proved the best giving 37,0 and 58,9 g/ha grain yield, and Hs, 4775/ha and Rs. 7711/ha as gross income respectively.
