Abstract

The experiments were conducted to study the effect of different levels of nitrogen and severity of pruning on growth, yield and quality of Phalsa (Grevia subinaequalis L.). The pruning level at 90 cm (P4) had significantly maximum number of canes (13.66), number of sprouted shoots/cane (29.29), number of fruiting/nodes/shoot (29.29), number of fruits/node (9.18) and number of fruits/bush (4327.28), respectively which ultimately leads to maximum fruit weight (0.59 g), fruit yield/bush (4.25 kg) and fruit yield/hectare (80.5 kg). Moreover, total soluble solids (16.17°Brix), acidity (2.86%) and total sugars (11.22) were also recorded high in light pruning (P4). Regardless of severity of pruning, application of nitrogen at 100 g/bush showed significantly maximum number of cane bush (11.08), number of sprouted shoots/cane (23.91), number of fruiting nodes/shoot (23.88), number of fruits/node (8.36), number of fruits/bush (6371), fruit weight/bush (0.579 g), fruit yield/bush (3.61 kg) and fruit yield (6080.8) whereas minimum in respect to all parameters were recorded in P1 level of pruning (ground level).
