Abstract
A field experiment was conducted on onion var. GWO-1 in medium black calcareous soils (Typic Ustocrepts) using fertility gradient approach and fertilizer prescription equation were calculated. The results of follow up trails indicated that the yields targets were achieved below ±10 per cent variation but adjusted fertilizer prescription equation were fitted only at yields targeted of 175 to 225 qha-1 yield of onion. The income/cost ratio for the additional produce obtained over recommended dose 19.5 and 17.2 for onion bulb yield at targeted of 200 and 225 qha-1, respectively.
