Effect of Different Phosphorus Level on Growth and Yield of Garden Pea (Pisum sativum L.)

Abstract

A study was done to understand the effect of different levels of phosphorus on growth and yield of Garden pea variety Pusa Pragati. The investigation was carried out at Field of Horticulture Department, School of Agriculture Research and Technology, Sardar Patel University, Balaghat, (M.P.) during the Rabi season of 2023-24. The aim was to investigate the effect of different phosphorus level on the growth, development, yield attributes, seed quality, plant and soil chemistry of garden peas. The study included seven treatments out of which T1 (CONTROL) with no fertilizer and six different phosphorus levels (T2: 100 kg P2O5/ha, T3: 90 kg P2O5/ha, T4: 80 kg P2O5/ha, T5: 70kg P2O5/ha, T6: 60 kg P2O5/ha, T7: 50 kg P2O5/ha). The field trials were set up in a RBD design with three replications. The results indicated that phosphorus application significantly influences growth and yield traits, with the highest levels (100 kg P2O5/ha) promoting early flowering, seed maturity, increased Leaf area index (LAI), plant height and improved seed yield. However, medium phosphorus levels (80kg P2O5/ha) yielded comparable results.
