Influence of Pre Sowing Seed Treatments with Biofertilizers and Plant Growth Regulators on Growth, Yield and Yield Attributing traits of Field Pea (Pisum sativum L.) Var. Rachna

Abstract

The field experiment was conducted during Rabi Season 2021-22 at field experimental centre at Genetics and Plant Breeding Naini Agricultural Institute, SHUATS, Prayagraj, (U.P). The soil of the experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.36 %), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha). The experiment was laid out in Randomized Block Design with thirteen treatments including control which were replicated thrice. The treatments were as follows, TO- Control, T1, T2, T3- Rhizobium - 10%, 15%, 20%, T4, T5, T6-Azospirullum – 5%, 10%, 15%, and T7, T8, T9-Gibberellic acid (GA3)-50ppm, 75ppm, 100 ppm, T10, T11, T12- NAA -10 ppm, 15ppm, 20ppm respectively. The experiment results revealed that seeds treated with T9-Gibberellic Acid-100% ppm gave better results followed by T3-Rhizobium@ 20% and T12-NAA @20 ppm than other treatments viz, Field emergence (80.06), Plant height (94.75cm), Days to 50% flowering (68.71), Days to Maturity (120.98), number of branches per plant (7.24), number of pods per plant (20.86), number of seeds per pod (4.55), seed yield per plant (17.44 g), Seed yield per plot (269.61  grams), Biological yield (50.78 grams), Seed index (23.91), Harvest index (34.24%) were recorded significantly higher compared to other treatments.
