The present investigation was conducted during 2022-2023 at DAV University, Jalandhar, to find out the effect of spacing and sowing dates on growth, yield and quality of pea (Pisum sativum L.). The experiment consisted of nine treatments which have three different sowing dates (5 November, 12 November and 19 November), spacing (20 cm×10 cm, 30 cm×10 cm and 40 cm×10 cm) and variety (Punjab-89) that is laid in RBD (Randomized block design) with three replications. It was observed that the plants grown in treatment T1 (5 Nov, 20 cm×10 cm) resulted better in most of the growth, yield and quality parameters (50% flowering, number of branches per plant, number of leaves per plant, number of flowers per plant, plant height, leaf area, Chl-a and chl-b content, Total Chlorophyll content, Total starch content and total phenolic content. T2 (5 November, 40 cm×10 cm) showed the best result in 50% germination, number of pods per plant and number of seeds per plant as well as, T5 (12 November, 30 cm×10 cm) showed the best result in quality parameters (leaf area, total protein content, total flavonoid content and total phenolic content). T8 (19 November, 40 cm×10 cm) showed the best result in total soluble solids. The economic analysis depicted the maximum gross income, net income and benefit-cost ratio from treatment T1 (5 Nov, 20 cm×10 cm). So, we conclude that crop sown in 5 November with three different spacing (20 cm×10 cm, 30 cm×10 cm and 40 cm×10 cm) proved to be best in growth, yield and quality parameters.
