The objective of this study was to assess the influence of different planting dates on the growth of groundnut (Arachis hypogaea L.). The experiment utilized a randomized block design, employing four planting dates (November 1st, November 15th, December 1st, and December 15th) with five replications at Instructional Farm Vellanikkara, Kerala Agricultural University, during 2019–2020. The chosen variety for the study was TNAU CO-6. Continuous monitoring of crop development data was conducted in the experimental plot. An analysis of variance was performed to evaluate the impact of planting dates on various crop growth indicators, including plant height, leaf number, dry matter accumulation, and leaf area index. Overall, the results demonstrated a significant influence of planting dates on these key parameters. Notably, the November 1st planting consistently exhibited significantly higher values compared to other dates, emphasizing the pivotal role of selecting an optimal planting date. November 1st, in particular, emerged as highly favorable for achieving superior crop growth.
