Mulberry growth parameters

=Three types of artificial diets viz., Artificial diet1, Artificial diet2 and Artificial diet3 with different compositions were used for rearing Kolar Gold race of mulberry silkworm, Bombyx mori L. where the diets were fed up to initial three instars and the later two instars were reared on natural diet (untreated leaves). Formulated diets were compared with natural diet and the observations on growth parameters were recorded.

Study on assessing the toxic effects of fungicides on silkworm (Bombyx mori L.) and also on cocoon and silk quality parameters revealed that carbendazim 50% WP and wettable sulphur 80% WP at 0.1% were found to have no toxic effect by showing zero larval mortality at three days after treatment. The larval weight and larval length of 29.33 g and 5.73 cm respectively in carbendazim 50% WP and 29.10 g and 5.42 cm) in wettable sulphur 80% WP was found to be higher than other fungicidal treatments.

The study revealed that, maximum number of shoots (12.44, 16.40, and 19.57) and more shoot length (29.85, 76.87, 109.32 cm) was observed in Tr-10 variety on 15, 30th and 45 days after pruning. Further, the data on maximum number of leaves (9.20, 15.89, 21.99) was recorded in S-34 variety whereas the internodal distance (5.67, 7.69 8.08 cm) and leaf area (58.32, 175.12 and 224.04 cm2 ) was recorded in Tr-10.

The study revealed that, application of seriwaste bio-digester effluent to mulberry along with other organic manures increased the rearing and cocoon parameters providing all the essential nutrients for mulberry growth compared to application of sole inorganic fertilizers and in turn it contributed for quality cocoon production. Utilization of sericulture waste generated during mulberry cultivation and silkworm rearing leads to generate additional income, entrepreneurship development in sericulture and value addition in turn contributing to achieve sustainability in sericulture.

Field experiments were carried out during Kharif and Rabi seasons of two years at the Department of Sericulture, Tamil Nadu Agricultural University, Coimbatore to study the influence of different pruning heights in mulberry and integrated nutrient management (INM) practices on growth, leaf and cocoon productivity as well as profitability in mulberry. The experiments were laid out in a strip plot design with three main plot treatments and six sub plot treatments replicated thrice.

Feeding is the most important factor in silkworm rearing, as it has a direct impact on growth and development of worms. Silkworm requires feed five times a day at an interval of five hours. However, the rearers of J&K state feed the worms two times only, resulting in lower cocoon yield. Feeding of quality mulberry leaves has a great impact on biology and physiology of silkworm Bombyx mori L. The study revealed 3 feedings per day was statistically at par with 4 feedings in terms of various parameters including larval survival percentage i.e. 93.50 ± 0.76 for 3 feedings and 95.00 ± 0.
