The pea (Pisum sativum) is a high value and widely cultivated crop in the North-Eastern Region (NER) of India. Achieving successful pea production relies on efficient agronomic practices and water management practices. The Northeastern Region (NER) of India experiences an annual average of 2450 mm rainfall. Despite the region's significant annual rainfall, cultivation of winter crop is challenging during the rabi season due to erractic rainfall and lack of irrigation facilities, so the crop depends on residual moisture from the monsoon rains. This erractic rainfall and inadequate irrigation facilities can lead to inadequate water availability for crop growth, affecting germination and development of winter crops. To solve this problem, variety of mulching materials can be adopted to reduce in-situ soil moisture stress during the winter season. Jute, a biodegradable natural fiber, is utilized as mulch in agriculture for conserving soil moisture in situ. It has been found to be effective in increasing crop yields, improving water-use efficiency, increasing profitability, reducing weed growth, and enriching the soil with nutrients. Using jute mulch during the rabi season in the hilly areas of the North-Eastern Region (NER) can significantly enhance crop productivity and raise cropping intensity. Therefore, an agronomic investigation titled “Performance assessment of Pea (Pisum sativum) cultivars under jute-based non-woven mulch” was carried out to increase pea cultivar production, quantify water productivity, and determine the benefit-cost ratio (BCR). The experiment was done in a split-plot design with four mulch treatments: un-mulched, 400 gsm, 500 gsm, and 600 gsm, in the main plots, and three cultivars: IPFD-99-25, IPFD-99-13, and IPF-1-10 under the sub-plots, with three replications. The study revealed that the 600 gsm mulch significantly enhanced growth parameters and yield attributes compared to other treatments. Specifically, the plants under 600 gsm mulch achieved a plant height of 55.67 cm, 13.20 branches per plant, and a dry matter accumulation of 33.19 g per plant. Yield attributes included 8.87 pods per plant, 6.89 seeds per pod, and a green pod yield of 8.83 t ha-1. The maximum value for water productivity was recorded under 600 gsm mulch (40.87 kg ha-1mm-1) and the lowest value was recorded under unmulch (16.94 kg ha-1mm-1). Among the cultivars, IPFD-99-25 (V1) demonstrated superior growth with a plant height of 54.10 cm, 12.93 branches per plant, and 32.12 g per plant dry matter accumulation. The maximum water productivity was observed with cultivar IPFD-99-25 (V1) 35.27 kg ha-1 mm-1, while the lowest was observed in IPFD-1- 10 (V2) 30.00 kg ha-1 mm-1. The 600 gsm mulch (M4) recorded the highest gross returns of ₹ 2, 73,055.56 ha-1, net returns of ₹ 1,82,190.56 ha-1, and a benefit-cost ratio (BCR) of 3.01. Cultivar IPFD-99-25 (V1) recorded the highest economic yield of 7.62 t ha-1, biological yield of 14.76 t ha-1, gross returns of ₹ 2,43,729.17 ha-1, net returns of ₹ 1,63,364.17, and a benefit-cost ratio (BCR) of 3.00. Therefore, in the hilly regions of the North-Eastern Region (NER) where soil moisture retention is critical during the rabi season, the application of 600 gsm mulch combined with the IPFD-99-25 (V1) cultivar is recommended to enhance cropping intensity and pulse productivity.
