Effect of in situ Rainwater Harvesting and Mulching on Growth, Yield and Fruit Quality in Mango Var. Arka Neelachal Kesri in Eastern India

Abstract

A field study was conducted at Central Horticultural Experiment Station (ICAR-IIHR), Bhubaneswar, India, during 2007-2013 in a new mango orchard of the variety 'Arka Neelachal Kesri' at 5m x 5m spacing, to conserve rain-water and to enhance soil moisture availability during dry periods for augmenting plant growth and fruit production. Among the four in situ rain-water harvesting techniques (cup-and-plate, half-moon, full-moon, and trench) evaluated in combination with three types of mulch (no mulch, inorganic mulch, and organic mulch), the cup-and-plate system resulted in maximum annual increment in vegetative growth and fruit yield (4.67kg/plant), while, organic (paddy straw) and inorganic (black polythene, 100μ thickness) mulches improved vegetative growth, fruit yield and TSS in fruit significantly over no mulch.
