Abstract
The field pea crop was very suitable for many areas but due to less soil fertility the quality and quantity of grains was reduced. The growth parameters like plant height, number of leaves, number of branches all was affected and same in the yield parameters like number of pods per plant, number of seeds per pod, etc. The flower initiation was delayed, and weather conditions were not in the favor always. So, the plant growth regulators were required to reduces this stress from the field pea crop. A field experiment was conducted in the rabi season of 2022 at the research farm of Lovely Professional University (India). The treatments comprised with plant growth regulators (NAA (naphthalene acetic acid) and GA3 (gibberellic acid) @ 25 and 50 ppm), antioxidants (acetylsalicylic acid and ascorbic acid @ 100 and 200 ppm), biofertilizers (rhizobium and PSB (phosphate solubilizing bacteria)) and control in randomized block design. Growth regulators showed profound results in case of morphology of plant whereas antioxidants effect was not remarkable. The biofertilizers improved the root growth and development. All the treatments statistically showed best result as compared to control. Among all treatments GA3 @50 ppm showed best result in case of physio-morphological characters viz., plant height, number of leaves, number of branches, leaf area, and chlorophyll index as they increase as the dose of concentration increased. GA3 had a profound effect on hastening the initiation of flowering by 3 – 5 days over control, whereas other plant growth regulators, antioxidants did not affect the days to flowering. NAA has profound effect on the quality attributes i.e., seedling length, seedling dry weight, and vigor index as compared to GA3. In case of yield attributes GA3 and PSB resulted better over other treatments. The result suggested that the use of GA3 and NAA as plant growth regulators are most beneficial for the growth, yield, and phenology of field pea.
