Effect of Weed Management Practices on Growth, Yield and Quality Parameters of Field Pea (Pisum sativum var. arvense)

Shambhavi and Anita Jaswal

Abstract

Peas, which are classified as a significant winter vegetable in the leguminosae family, are highly susceptible to weed infestation. Weeds are plants which are deemed unwanted and have a negative impact on the effective utilization of land and water resources. Crop plants have decreased production due to competition with other plants for nutrients, moisture, and light resources. When weed control measures are not implemented effectively, there is a decrease in crop yields. The extent of this yield reduction is influenced by the specific weed species present and the overall abundance of weeds in the area. A research investigation was undertaken to examine the impact of different methods of weed management on the growth of plants, yield, and parameters contributing to yield in pea cultivation. The experiment was conducted using a randomized complete block design, with nine treatments that were replicated three times. In the 2022 – 2023 rabi season, the plots with black polythene mulch exhibited the earliest germination, with a mean duration of 5.33 days. This was followed by the control plots and hand weeding plots, which had a mean germination duration of 6.33 days. The black polythene sheet exhibited the following characteristics: the tallest plants (measuring 72.23 cm), number of leaves (83.83), fresh weight (78.66 g), dry weight per plant (19.83 g), number of primary branches per plant (34.00), chlorophyll index (48.03 SPAD), leaf area (28 cm2), number of pod per plant (42.00), pod length (10.06 cm), no of seeds per pod (9.33), seed weight per plant (9.36) and seed index (19.70 g). The implementation of black polythene sheet resulted in a notable augmentation in pod yield, reaching 2096.2667 kg ha-1, which was substantially superior to the yields observed in all other treatments. The findings indicated that black polythene sheet and hand weeding was the most effective strategy in reducing weed density, as well as boosting growth, and yield metrics during both years..
