Growth and yield parameters of Pea (Pisum sativum L.) as influenced by different priming treatments

Abstract

Current study was conducted at the experimental farm, Department of Agriculture, Sant Baba Bhag Singh University, Jalandhar, Punjab, during the Rabi season of 2022-23. The Randomized block design was used with seven treatments replicated thrice. Various priming agents viz., water (hydropriming), rhizobium inoculants, KNO3, GA3, H2O2 and neem leaf powder, at different concentrations were used to treat the seed for 8 hours. Findings unveiled that growth parameters viz., days to emergence, plant height and number of branches per plant, days to flower initiation, days to 50% flowering and number of flowers per plant were recorded maximum with the application of treatment (T4) i.e., seed priming with GA3 @ 100 ppm, followed by treatment (T3) i.e. seed priming with KNO3 @ 3% (30gm). Similarly, yield attributes viz., number of pods, number of seeds per pod and seed yield per plant, pod yield per plot, maximum average yield also had maximum reported values in treatment T4 followed by T3.
