Abstract
Plant growth regulators (PGR) enhance the growth and yield of rice. This study aimed to determine the effects of growth regulators on the growth and yield of hybrid lowland rice, determine the kind of growth regulators and their appropriate concentrations that would give the optimum yield of hybrid lowland rice, and evaluate the profitability of rice production per hectare using the different plant growth regulators applied to hybrid lowland rice. The experimental area was laid out in Randomized Complete Block Design (RCBD) with three replications. The treatments were T = control, T = 500 ppm PBZ + RR, T = 1000 ppm PBZ + RR, T = 0 1 2 3 500 ppm PBZ + 500 ppm ANAA + RR, T = 500 ppm ANAA + RR, T = 1000 ppm ANAA 4 5 + RR, and T =120-60-60 kg ha-1 N, P O K O [RR]). Results revealed that the 6 2 5, 2 application of plant growth regulators significantly affected the agronomic characteristics of hybrid lowland rice. Rice plants applied with paclobutrazol regardless of the level (T and T ) and unfertilized plants (T ) headed and matured 1 2 0 earlier than the other treatments. The application of PBZ and NAA regardless of the concentration (T -T ) significantly did not vary in all the yield components of hybrid 1 5 rice. However, rice plants applied with 500ppm + RR (T ) obtained the highest net 1 income of Php 59, 496.33, which is slightly higher than plants applied with 1,000 ppm PBZ + R.R. (T ) and inorganic fertilizers alone (T ) which had net incomes of 2 6 PhP58,215.17 and Php 54, 436.33, respectively.
