Abstract: The result of the field experiment carried out consecutively for three years in a conservatory of Bidhan Chandra Krishi Viswavidyalaya situated at Kakdwip, South 24-Parganas, West Bengal to study the effect of different mulches on growth, water-use efficiency and monetary return of betelvine cv. Mitha, revealed that maximum vine elongation (26.55 cm), number of leaves per vine (27.06), leaf weight and leaf area index were recorded under poly-mulch treatment. The increment of leaf yield was maximum (42.34%) over control due to poly-mulch with reduction of water utilization by 557.4 mm. The maximum water-use efficiency (52.94 kg ha-1 mm-1) was recorded under poly-mulch treatment followed by straw and weed mulch. The per hectare per annum monetary return was maximum (Rs 19,56,492) under poly-mulch treatment which was 1.4 times higher over control.@
