EFFECT OF INM PRACTICES ON THE MORPHOLOGICAL, PHYSIOLOGICAL AND BIOCHEMICAL PARAMETER OF ARJUN LEAF PRIMARY HOST PLANT OF Antheraea mylitta D.

Abstract

The present study was conducted to investigate the effect of Integrated Nutrient Management practices on the different  parameter of Arjun leaf the primary host plant of Antheraea mylitta D. Eleven different combination with three replication were laid out in Randomized Complete Block Design at the field of Research Extension Centre, Kapistha. The obtained results showed that morphological, Physiological and Biochemical parameter of Arjun leaf showed significant difference. The Arjun leaf length was recorded highest in K₁₁ (17cm) was on par with K₉ (17cm). Highest leaf breadth was recorded in K₁₀ (6.2cm) was applied with 75%RDF+Poultry manure+ AB+PSB. Leaf weight was recorded highest in K₇ (2.84g), lowest in K₁(1.21g). Number of leaves was recorded highest in K₆ (1816) over the control. The leaf yield was recorded highest in K₁₁ (3735). Leaves dry matter production was highest in K₈ (469.56g) over the control. Relative water content was highest in K₅ (87.3%). The initial Electrical Conductivity was recorded highest in K₉ (0.037dSm^-1) and after 10 min EC was found to highest in K₉ (0.111dSm^-1). The Chlorophyll ’a’ was recorded highest in K₉ (3.39), Chl’b’(2.36)and total chlorophyll in K₉(5.75) was recorded highest. The result were found significant due to effect of INM practices which provided the nutrients element needed by plants.
