Abstract
An agro-meteorological investigation was undertaken during Rabi Season (2019-20) at Farm, Department of NRM, College of Forestry, SHUATS, Prayagraj State (India). The experiment followed split plot design (SPD) with three replications, included 27 treatment combinations based on three sowing windows—46th meteorological week (MW) (November 12–18, D1), 48th MW (November 26–December 2, D2), and 50th MW (December 10–16, D3)—as the main plot factor and three field pea varieties viz. Rachana (V1), Malviya-15 (HUDP-15) (V2), and Aparna (V3)—as the sub-plot factor, and among the sowing dates, the early sown crop (D1) accumulated the highest growing degree days (GDD), heliothermal units (HTU), and photothermal units (PTU), resulting in the longest seed development duration (SDD). Among the cultivars highest SDD was found in Rachana while the GDD, PTU was found highest in Malviya-matar and HTU was observed in Aparna Variety.
