Description The investigation on “Impact of spacing in mulberry on leaf quality and silk cocoon
yield” was carried out at UAS, Bangalore, College of Sericulture Chintamani, during
2013-14. Growth and yield parameters of mulberry viz., plant height (183.44 cm), mean
number of branches per plant (13.00) and leaf yield per plant (1234.90 g) was found
higher in 9×3 ft spacing. Carbohydrate content was found highest in 3×3 ft spacing
(24.04%) crude protein in (5+3)×2ft spacing (6.06 %). Total chlorophyll was recorded
highest in (6+3)×3 ft spacing (1.92 mg/g), moisture retention capacity was highest in
(6+3)×3 ft spacing at 3, 6, 9, 12 h after harvest (88.12 %, 86.02 %, 85.16 %, 84.16 %
respectively).
Leaf NPK content was found maximum in (5+3)×2 ft spacing (0.97 %, 0.82 %, 4.71 %
respectively). Total larval duration (624.96 h and 616.80 h), weight of 10 matured larva
(30.33g and 26.21), ERR (89.74% and 87.64%), was found highest in 9×3 ft spacing in
first and second rearing respectively. Weight of ten cocoons (g), cocoon yield (kg/400
worms), single cocoon filament length (m), shell ratio (%) and denier was recorded
highest in 9×3 ft spacing both in first and second rearing (19.84 (g), 0.69 (kg), 790.52(m),
18.72 (%), 2.87 respectively in first rearing), (17.72 (g), 0.65 (kg), 751.34 (m), 16.17 (%),
2.53 respectively in second rearing)
In the present investigation it was observed that by increasing the spacing, the quality of
leaves improved and no difference was found in leaf yield.
