A field experiment was conducted on pearlmillet var. GHB-526 in medium black calcareous soils (Vertic Ustocrepts) using fertility gradient approach and fertilizer prescription equation were calculated. The results of follow up trials conducted at different location showed that the economics of fertilizer use based on soil test for achieving maximum yield indicated an additional benefit over general recommended dose at tested grain yield targets of 24, 30 and 36 q ha-1. The income/cost ratios of the additional produce obtained over recommended dose were 16.79, 4.21 and 3.34 for pearlmillet grain yield at targets of 24, 30 and 36 q ha-1, respectively.

Abstract


A field experiment was conducted on pearlmillet var. GHB-526 in medium black calcareous soils (Vertic Ustocrepts) using fertility gradient approach and fertilizer prescription equation were calculated. The results of follow up trials conducted at different location showed that the economics of fertilizer use based on soil test for achieving maximum yield indicated an additional benefit over general recommended dose at tested grain yield targets of 24, 30 and 36 q ha-1. The income/cost ratios of the additional produce obtained over recommended dose were 16.79, 4.21 and 3.34 for pearlmillet grain yield at targets of 24, 30 and 36 q ha-1, respectively.
