Abstract
A field experiment was conducted to study the effect of micronutrients and
biofertilizers on mulberry in under field condition. Different combination of
micronutrients and biofertilizers were used in this study to assess the growth
and yield of mulberry and silkworm. Among the treatments, application of
100 % RDF + Soil application of ZnSO4, Fe SO4, MnSO4 and MgSO4 @ 25 kg
ha-1 each + Recommended dose of biofertilizers (Azos, Phospho and Potash
mobilizer each @ 1500 ml ha-1) recorded superior growth and yield attributes
viz., plant height (198 cm), number of shoots (14 plant-1), number of leaves
(646 plant-1), leaf area (101146 cm 2 plant -1) and leaf yield (1218.369 g
plant-1) with high leaf moisture retention percentage of 93.94. Yield traits
of silkworm such as larval weight, effective rate of rearing by number,
effective rate of rearing by weight, single cocoon weight, single shell weight
and number of cocoon per kilogram were also higher compared to other
treatments.
Key words : Mulberry, Micronutrients, Biofertilizers, Growth attributes, Yield, Silkworm.
