Abstract
A Field experiment was carried out at Crop Research Station, (ANDUAT), Ghaghraghat, Bahraich to evaluate the effect of two levels of fertilizers (F1: 60-30-20 & F2: 120-60-40 NPK kg/ha) on grain yield of Seven Advance Varietal Trial-2 rice cultures (IET 29026, IET 27538, IET 29031, IET 29032, IET 26744, IET 28281 and IET 27547) under rainfed shallow land in split plot design with three replications. Soil of the experimental field was sandy loam with pH 7.2, organic carbon 0.40%, Nitrogen 200 kg/ha, P2O5 24 kg/ha and K2O 234 kg/ha. Results revealed that application of higher level of fertilizers significantly increased the grain yield of rice cultures. IET 26744 recorded maximum grain yield (5.25 t/ha) followed by IET 29032 (5.20 t/ha) at higher dose of fertilizers and per cent increase over lower dose were 55.78 and 67.20, respectively. At 50% recommended dose of fertilizers variety Swarna-Sub 1 yielded maximum grain (3.54 t/ha) followed by IET 26744 (3.37 t/ha). All cultivars yielded higher at 100 per cent recommended dose of fertilizers.
