Abstract:
The field study was conducted at Horticulture Garden, Bihar Agricultural College, Sabour during 2014-15 and 2015-16 to response of different dose of nitrogen strategies on phenology, yield and quality of mango (
Mangifera indica L.) cv. Amrapali under high density planting (HDP). The experiment was laid out in factorial randomized block design with four levels of nitrogen (60g, 80g, 100g, and 120g/tree) treatments replicated thrice. The results obviously indicated that the every level of nitrogen significantly influenced the morphology, yield and quality of mango. Morphological parameter
i.e. increase in tree height (29.22%), canopy spread (N-S 14.71%), canopy spread (E-W 13.42%), canopy volume (13.01%) and physical parameters of fruits like highest fruit length (10.35cm), fruit width (6.65cm), fruit weight (190.61g) and fruit volume (188.16cm
3) were observed with the application of 120 g nitrogen per tree, while as regard with yield and quality parameters like maximum fruit set (17.06%), fruit retention (10.03%), minimum fruit drop (90.21%), pulp: peel ratio (4.38), pulp: stone ratio (4.49), pulp per cent (66.44%), fruit yield (11.29 kg/tree), TSS (23.30
0B), TSS/acidity ratio (147.44), total sugars (18.07%), total carotenoids content (18.46mg/100g pulp) ascorbic acid content (38.47 mg/100g pulp) and minimum acidity (0.164%) were noted with the application of 100g nitrogen per tree. On the other hand, lowest morphological, yield and quality parameters were reported with the application of nitrogen @ 60g/tree.
