An economics of rice cultivation through appropriate management of zinc under northern gangetic alluvial plain

A field experiment was conducted to study the economics of rice cultivation through appropriate management of zinc at Agricultural Research Farm of Institute of Agricultural Sciences, Banaras Hindu University during the two consecutive kharif (rainy) seasons of 2010 and 2011. The experiment was laid out in randomized block design with three rice varieties (HUR-105, HUBR 2–1 and PHB-71) and seven zinc treatments. The hybrid PHB 71 showed the highest gross return of 78007 and 79570, but HUR 105 recorded maximum net return of 46886 and 48180 and B: C ratio 2.58 and 2.63 in year 2010 and 2011, respectively. Amongst the zinc treatments, application of Zn (EDTA) 0.25 kg ha-1 at basal + Zn (EDTA) 0.05% sprays at maximum tillering stage resulted in maximum gross return of 87211 and 88531), net return of 57572 and 58892 and B: C ratio 2.94 and 2.99 and was found economically feasible during both the years of experimentation.
