Abstract:

A field experiment was conducted in Hisar, Haryana, India during the rabi season of 2000-01 and 2001-02 to assess the effect of integrated nutrient management of wheat under adequate and limited irrigation supplies. The treatments comprised 2 irrigation schedules: adequate irrigation one each at crow root initiation (CRI), tillering, jointing, flowering and milking and limited irrigation one each at CRI and flowering; and 10 levels of nutrients: no N (control, N0), 150 kg N/ha (N1), farmyard manure (FYM) at 10 t/ha (N2), 187.5 kg N/ha+FYM at 10 t/ha (N3), Azotobacter at 25 g/kg seed (N4), 112.5 kg N/ha+Azotobacter (N5), FYM at 10 t/ha+Azotobacter (N6), 112.5 kg N/ha+FYM at 10 t/ha+Azotobacter (N7), 150 kg N/ha+FYM at 10 t/ha+Azotobacter (N8), and 187.5 kg N/ha+FYM at 10 t/ha+Azotobacter (N9). N9 recorded the highest crop growth rate and relative growth rate during all the stages of crop growth beyond 39 days after sowing both under limited and adequate irrigation conditions. Under adequate irrigation, N9, being at par with N3 and N8, recorded significantly the highest grain yield (5298 kg/ha) whereas under limited irrigation, N7 was at par with these treatments. Mean maximum water-use efficiency values of 15.56 and 17.68 kg/ha-mm were recorded with N9 both under adequate and limited irrigation during 2000-01 and 2001-02.
