Description Investigations on “Studies on Time and Severity of Pruning in Mulberry (Morus
alba L.)” were carried out at the Experimental Orchard of the Department of Horticulture,
CCS Haryana Agricultural University, Hisar, during the year 2012. Experiment was laid out
with Randomized Block Design allocating three pruning times i.e. first week of January, third
week of January and first week of February and four pruning severities i.e. control, 20 per
cent, 40 per cent and 60 per cent removal of previous season growth comprisisng 12 treatment
combinations altogether. During the course of studies, it was found that pruning time did not
affect any parameter except time taken for fruit ripening, significantly. Early fruit ripening
observed with the delay in pruning time. Among different treatment combitions the
minimum days (83) for fruit ripening were recorded in trees pruned at 60 per cent
severity in 1st week of February. As far as the pruning severity is concerned, the minimum
days to sprouting (30.2), time taken for flower initiation (38.9 days) and acidity (0.271 %)
were observed under 60 per cent pruning severity. Bud sprouting percentage, shoot length,
shoot diameter, number of leaves per shoot, leaf area increased with increasing pruning
severity. The maximum bud sprouting percentage (83.9 %), shoot length (282 cm), shoot
diameter (2.64 cm), number of leaves per shoot (15.4) and leaf area were observed under 60
per cent severity of pruning. Pruning severity had also significant effect on fruit size and fruit
quality. Highest fruit size (fruit length and diameter), TSS (28.8 %), total sugar (18.3
%), reducing sugar (12.0 %) and ascorbic acid (49.3 mg/100g) were observed under
pruning level of 60 per cent. The maximum yield was observed under 40 per cent
pruning severity.
