Abstract

Terminalia tomentosa is a primary food plant of Antheraea mylitta Drury a polyphagous insect of Saturniidae family which is exploited commercially for the production of silk. Good quality of silk production depend on the nutrient of leaf. So, to optimize the nutrient of leaf integrated nutrient management practices has been used to increase soil fertility and to supply plant nutrient at an optimum.

In order to evaluate the effect of INM practices on the leaves parameters of Terminalia tomentosa food plant of Antheraea mylitta Drury. An experiment based on randomised complete block design with 21 treatments and three replication was conducted at Central Tasar Research and Training Institute, Nagri, Ranchi in the year 2019–20.

Results revealed that the application of INM treatments are significant on various leaf parameters. Highest single leaf length and breadth mean was observed in T19 (23.29 cm; 11.96 cm) was applied with 75% RDF through fertilizer+25% through vermicompost+ Azotobacter + PSB, weight of single leaf was found to be highest in T13 (5.19 g). The number of leaf was recorded highest in T19 (1892). The fresh leave yield ranged from 1617.317–5208.224 g with average mean of 4085.72 g, T19 (5032.1 g) recorded the highest fresh leaf yield. The dry matter content was found highest in T19 (340.56 g). The moisture content was recorded higher in T4 (71%) followed by T16 (69%).
