Abstract
The present investigation was carried out at Horticulture Research Centre, Patharchatta, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, Distt. Udham Singh Nagar (Uttaranchal) to study the effect of fertigation and plastic mulch on growth, yield and fruit quality of mango cv Dashehari. Maximum scion height, scion girth, canopy diameter, canopy volume and fruit yield (in number and weight) were recorded with full recommended dose of fertilizers with mulch through fertigation. Maximum shoot length and leaf area were recorded with drip irrigation at 0.6 ‗V‘ level with mulch having 75 and 100 per cent dose of fertilizers through fertigation, respectively. Maximum fruit set and fruit retention was recorded with the treatment of drip irrigation at 0.8 ‗V‘ level without mulch with full recommended dose of fertilizer application through fertigation while maximum fruit volume and TSS was recorded in treatment with drip irrigation at 0.6 ‗V‘ level without mulch with 50 per cent recommended dose of fertilizers. Maximum shelf life of mango after 8 days of harvesting was recorded in the plants treated with drip irrigation at 0.6 ‗V‘ level with mulch having 50 per cent recommended dose of fertilizer. Maximum nitrogen, phosphorous and potassium content of the leaves were recorded in the treatment which received either drip irrigation or conventional method of irrigation without mulch. There was no any significant effect of various treatment on length and girth of rootstock as well as on average fruit width. Mulching with irrigation delayed bud burst, flowering (50 %) but made early panicle emergence.
