Abstract:
The present investigation was carried out at Research Farm of Department of Floriculture and Landscape Architecture, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (H.P) during 2018-2019 under polyhouse condition with the objective to optimize the dose of jeevamrit for frond growth, production and longevity of Nephrolepis exaltata. Treatments comprised of different concentration of Jeevamrit applied both as drenching and foliar spray and Trichoderma spp @ 1kg/q FYM + Foliar application of Neem seed kernel extract and Garlic extract @ 5% each at 15 days interval, alternatively. The experiment was laid out in Randomized Block Design with 11 treatment combinations replicated thrice. The results revealed that treatment T₅ i.e. Jeevamrit @ 5% (Drench) + Foliar application of Jeevamrit @ 10% recorded maximum number of fronds per plant, frond length, length of the longest frond, plant spread, leaf area and number of pinnae per frond. Maximum frond width was recorded with Jeevamrit @ 2.5% (Drench) + Foliar application of Jeevamrit @ 10% application (T₂) which was found to be at par with T₅. Maximum number of frond yield per square metre, weight of individual frond and vase life were also registered in treatment T₅.
