Abstract

Being the second important stone fruit crop of Himachal Pradesh, nectarine still requires a great improvisation in floor management. Keeping this objective, a two year study was conducted with various orchard floor management practices on eight year old ‘Snow Queen’ nectarine trees during 2014 and 2015. The experiment was laid out in Randomized Block Design, having seven treatments including control and replicated four times. Among all treatments soil hydrothermal regimes were maintained effectively under grass mulch and black polythene mulch. Grass mulch recorded maximum increase in annual shoot growth (148.25 cm), per cent increase in trunk girth (11.49 %), per cent increase in tree height (14.46 %) and per cent increase in tree volume (40.84 %). Maximum fruit set (74.38 %) and fruit yield (26.09 kg/tree) was recorded under nylon mulch mat while minimum fruit drop (16.37 %) under grass mulch. Bicolour polythene mulch recorded fruit size (56.90 mm), fruit weight (100.97 g), fruit volume (102.94 cc), pulp to stone ratio (14.65), TSS (12.91 ºBrix), total sugars (9.58 %) and reducing sugars (4.10 %) along with maximum proportion (82.25 %) of “A” grade fruits.
