Foliar application of nano fertilizers to enhance growth and cocoon yield of mulberry silkworm, Bombyx mori

The objective of the current study was to boost the growth of the mulberry silkworm, Bombyx mori, and increase cocoon yield by
feeding the larvae on mulberry leaves sprayed with various doses of nano fertilizers, speci

ically nano NPK (19:19:19) at
concentrations of 2, 4 and 6 g/l, as well as nano urea at concentrations of 2, 4 and 6 ml/l. The application of nano fertilizers to the
leaves, followed by their consumption by silkworms from hatching until the spinning stage, resulted in notable improvements in
various economic parameters related to larval development, cocoon production, and silk quality. Among the different doses of nano
fertilizers assessed, it was observed that nano NPK (19:19:19) at a concentration of 6 g/l exhibited favorable outcomes in terms of
reduced larval duration, increased mature larval weight, improved effective rate rearing, enhanced silk productivity, cocoon yield,
greater cocoon weight, higher shell weight, improved cocoon shell ratio, increased pupal weight, greater silk gland weight, longer
cocoon
ilament length,

iner denier and the highest

ibroin protein, while concurrently having the lowest sericin protein content.
