Effect of integrated nutrient management on growth of senna (Cassia angustifoliaVahl.)

Abstract

Senna (Cassia angustifoliaVahl.) belongs to the family Fabaceae and is one of the most significant medicinal crops in India. India holds leading position in the production of senna crop and export of its produce to the world market, annually earning nearly 45 million. Almost all the senna leaves produced in India are exported and the major portion is transported to London market. Thus an experiment was conducted on the “Effect of Integrated nutrient Management on Growth of Senna (Cassia angustifoliaVahl.)” carried out at ParamathiVelur, Namakkal District, Tamil Nadu during the year 2019 - 2021. The field experiment was consisting of different combination of nutrients viz., recommended dose of fertilizers RDF, farmyard manure FYM, vermicompost VC and biofertilizers (Azospirillum AS and Phosphobacteria PB).The senna plants were planted in a plot with the size of 2.2x2.2 m2 with 35 plants @ 45 x 30 cm2 spacing. The experiment was laid out in Randomized Block Design with three replications and twelve treatments. Among the various treatments tried, plants supplied with T10 (75%RDF+FYM@10tha-1+Azospirillum@2.5kgha-1 + Phosphobacteria @ 2 kg ha-1) recorded maximum growth parameters such as plant height, number of branches plant-1, plant spread and leaf area plant-1.
