Growth and yield parameters of tree mulberry as influenced by different levels of secondary nutrients

Abstract

The study on “Performance of tree mulberry applied with secondary nutrients and its influence on silkworm (Bombyx mori L.)” was carried out in the established V-1 tree mulberry garden at College of Sericulture, Chintamani during 2022-23. The treatments were formulated based on the recommendation for sulphur application in mulberry and proposed the recommendation for calcium, magnesium and sulphur in the ratio of 3:1:0.9, respectively. The results revealed that RDF + Soil application of Ca:Mg:S :: 82.5:27.5:25 to tree mulberry garden recorded highest total shoot length, number of shoots/tree, number of leaves/tree, leaf area (cm2) and leaf yield, respectively on 45th and 60th days after application of fertilizers which are on par with RDF + soil application of Ca:Mg:S :: 66:22:20. The lowest observations was recorded in control (recommended dose of fertilizer + FYM).
