INFLUENCE OF PLANT GROWTH REGULATORS ON THE PLANT GROWTH AND SEED YIELD OF F1 HYBRID RICE (KRH-4)
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 42
Abstract
The research on the effect of plant growth regulators on the plant growth and seed yield of F1 hybrid rice (KRH-4) was conducted at the Zonal Agricultural Research station, VC Farm, Mandya, Karnataka during growing season’s kharif-2012 and rabi /summer-2012. The experiment was laid out in Randomized Complete Block Design with planting ratios 3: 8 (male to female ratio). The treatment viz., T1: GA3 @ 100ppm, T2: NAA @ 100ppm, T3: GA3 @ 50ppm + NAA @ 50ppm, T4: GA3 @ 100ppm + NAA @ 100ppm, T5: GA3 @ 25ppm and NAA @ 25ppm, T6: KNO3 @ 1.0 %, T7: Urea @ 2.0 % and T8: No foliar spray (Control) and two foliar sprays (first spray at 5 % flowering and 2nd spray one day after1st spray) were imposed only on female lines. The application of GA3@ 100ppm give better seed yield (1981 kg/ha and 3096 kg/ha) over control 1013kg and 1285 kg/ha during kharif and rabi /summer season.
