Effect of Organic Mulches on Yield, Water Productivity and Economy of Garden Pea Cultivars

Abstract

Mulching techniques that are adaptive and extremely successful may be able to reduce the detrimental impacts of crop production and water stress on different varieties of peas in a climate change scenario. Field experiment was carried out in the Umroi region of Meghalaya during the rabi season (2020–2021) for this reason. This study used a split-plot design with three organic mulches as the main plot treatment and four pea types as the sub-plot treatments, which was replicated three times. The field trial showed that paddy straw mulch significantly outperformed both weed mulch and no mulch in terms of green pod yield, water productivity, and benefit cost ratio, with values of 89.33, 54.14 kg ha-1 mm-1, and 3.16, respectively.VM 12 greatly topped other cultivars in terms of green pod yield, water productivity, and benefit-cost ratio (BCR), with values of 89.78 kg ha-1, 54.41 kg ha-1 mm-1 and 3.33, respectively. The investigation showed that the best alternative agronomic strategy for achieving the maximum yield output of garden pea was paddy straw mulch, followed by weed mulch and un-mulch.
