Effect of Seed Treatment with Biofertilizers and Plant Growth Regulators on the Growth and Yield Attributing Characters of Field Pea (Pisum sativum L.)

Abstract

India is one of the largest producers of Field pea in the world and stands at the 5th place in the list of major pea producers next to Russia. A field experiment was conducted during Rabi  2021 at Crop Research Farm, Department of Genetics and Plant Breeding, SHUATS, Prayagraj (U.P). The experiment was placed in a randomized blocking design and consisted of 13 treatments and 3 replicates. The experimental results revealed that viz: Field emergence (%), plant height @ 30, 60 and 90 DAS, Days to 50% flowering, number of branches per plant, days to maturity. biological yield (gm), were recorded significantly highest in the treatment of T9: Gibberellic acid 100 ppm @12 hrs and yield parameters like Number pods per plant, Numbers of seeds per pod, Seed yield per plant (gm), Seed yield per plot (gm), Biological yield (gm), Seed index (gm) and Harvest index (%) were recorded significantly highest in the treatment of (T3) Rhizobium 30g @12 hrs as compared to the other treatment. It is clearly concluded from the research that T3: (Rhizobium 30g @12 hrs) significantly produced more yield. Hence the seed treatment of Rhizobium 30g @12 hrs could be recommended for the field pea.
