IV. Why this course ?
Silkworm is monophagous insect mainly feeding on mulberry and drawing its
nourishment for growth and development. It is mainly dependent on the quality of
leaf used for silkworm rearing. Production of quality leaf by adopting standard
package of practices to increase biochemical parameters of mulberry which are
directly involved not only to improve the quality parameters but also enhance
productivity per unit area. Therefore, the technical knowledge on nutritional
management of mulberry definitely helps in improving quality parameters of silk.
Hence this course.
V. Aim of the course
The main aim of this course is to provide both basic and applied knowledge on
nutritional management through different methods and means of application.
Further, it also provides nutritional requirement for different growth stages which
is required for silkworm growth and development. In addition, the complementary
use of chemicals, fertilizers, organic manure and bio-fertilizer is important to
maintain and sustain higher level of soil fertility and productivity. The principles
of manure and fertilizer application and their toxicity affect on quality parameters
of mulberry is the need of the hour. The beneficial effect of optimum nutrition and
toxicity due to excess nutrients application and deficiency symptoms due to lack of
nutrient availability affect the growth of mulberry. The academic knowledge on the
above helps in strengthening the skills of students to serve the farming community
effectively who are involved in quality leaf production and success of sericulture.
