Impact of iron nutrition on yield and economics of aerobic rice cultivars

Author(s): B Soumya, KP Vani, P Surendra Babu, V Praveen Rao and K Surekha
Abstract: A field experiment entitled was conducted during kharif season, 2012 and 2013 at College Farm, College of Agriculture, Professor Jayashankar Telangana State Agricultural University, Rajendranagar, Hyderabad to evaluate the response of cultivars and iron nutrition on yield and economics. Experiment was carried out with three rice cultivars i.e. Tellahamsa (M1), MTU 1010 (M2) and KRH 2 (M3) as main treatments and twelve iron nutrition treatments i.e, control (S1), basal application of iron sulphate @ 25 kg ha-1 (S2), basal application of iron chelate @ 25 kg
ha-1 (S3), 3 foliar sprays of iron sulphate from 21 DAS @ 7 days interval (S4), 3 foliar sprays of iron sulphate from 21 DAS @ 10 days interval up to maximum tillering (S5), 3 foliar sprays of iron sulphate from 21 DAS @ 15 days interval up to panicle initiation stage (S6), basal application of iron sulphate @ 25 kg ha-1 + 3 foliar sprays of iron sulphate from 21 DAS @ 7 days interval (S7), basal application of iron sulphate @ 25 kg ha-1+ 3 foliar sprays of iron sulphate from 21 DAS @ 10 days interval up to maximum tillering (S8), basal application of iron sulphate @ 25 kg ha-1 + 3 foliar sprays of iron sulphate from 21 DAS @ 15 days interval up to panicle initiation stage (S9), basal application of iron chelate @ 25 kg ha-1+3 foliar sprays of iron sulphate from 21 DAS @ 7 days interval (S10 ), basal application of iron chelate @ 25 kg ha-1+ 3 foliar sprays of iron sulphate from 21 DAS @ 10 days interval up to maximum tillering (S11), basal application of iron chelate @ 25 kg ha-1+ 3 FS of iron sulphate from 21 DAS @ 15 days interval up to panicle initiation stage (S12) as sub treatments laid out in split plot design replicated thrice. The higher grain and straw yield recorded with KRH 2 which was significantly superior over Tellahamsa and MTU 1010 during 2012 and 2013. Similarly, highest gross returns, net returns and B: C ratio was noticed with KRH 2 cultivar. Among sub plots, higher gross returns were observed with BA of IC @ 25 kg ha-1+ 3 FS of IS from 21 DAS @ 7 DI. But, higher net returns and B: C ratio was observed with BA of IS @ 25 kg ha-1 + 3 FS of IS from 21 DAS @ 7 DI.
