520			_aGarden pea (Pisum sativum L. var. hortense) is one of the popular and important high value crops grown in North-Eastern Region (NER). Effective agronomic production and water management techniques are crucial for the success of garden pea production. Although the NER experiences heavy annual average rainfall (>2000 mm), lack of suitable soil and water conservation results in severe water scarcity during the postmonsoon season. Meghalaya, a state in North Eastern Region (NER), India, faces similar situation, hence, little cultivation is possible during this period. To overcome this hindrance, ameliorating in-situ soil moisture stress by using various mulching materials can help to a great extent. Organic mulching may be an effective strategy to be implemented during the rabi season for the hilly regions of NER to increase crop production, thereby, enhancing cropping intensity. Keeping above considerations, field trial entitled “Impact of Organic Mulches on Productivity of Pea (Pisum sativum) Cultivars” was carried out with the view to enhance the performance of garden pea cultivars, to evaluate the water productivity and lastly, to estimate the benefit cost ratio (BCR) of garden pea crop. The experiment was laid out in a split plot design with four treatments (mulches), viz., i) un-mulch, ii) paddy straw mulch, iii) maize stover mulch and iv) weed mulch, applied @ 5 t ha-1 under main plot and four treatments (cultivars), viz., i) Arkel, ii) Punjab 89, iii) Pusa Pragati and iv) Pusa Prabal under sub-plot. This experiment was replicated thrice. From the field study, it is evident that, the best result under organic mulches was found to be shown by paddy straw mulch followed by weed mulch, maize stover mulch and lastly un-mulch. Growth parameters, viz., plant height (47.76 cm), no. of branches (12.73), dry matter production (6.35 g plant-1) were recorded highest from paddy straw mulch treatment. Also, the yield attributing characters, viz., pods per plant (7.87), seeds per pod (6.08) and green pod yield (8.51 tha-1) were found to be highest under paddy straw mulch. Among the cultivars, Punjab 89 (V2) cultivar performed better over the other three cultivars in terms of growth parameters and yield attributes. Plant height (47.49 cm), no. of branches (12.53) and dry matter production (6.33 g plant-1) were recorded highest in V2 cultivar. In terms of water productivity, highest value was recorded for paddy straw mulch (34.81 kg ha-1 mm-1) and lowest under un-mulch (13.52 kg ha-1 mm-1) and among the cultivars, Punjab 89 (V2) obtained the highest (30.23 kg ha-1 mm-1). The economic yield (7.38 t ha-1), biological yield (15.23 t ha-1), gross returns (₹ 1, 78,354.17 ha-1), net returns (₹1,29,301.67 ha-1) and benefit cost ratio (3.46) were found to be highest in V2 cultivar. Therefore, under the hilly regions of NER where retaining soil moisture is of great concern, mostly during rabi season, practicing paddy straw mulch with garden pea cultivar Punjab 89 (V2) not only intensifies cropping but will also increase the region’s supply of pulses and improve the pulse production of NER.
