Abstract
ABSTRACT
Boston fern is one of the most popular fern in floricultural industry as filler as it gives
freshness to the floral composition but there is lack of information regarding the production of cut
foliage of ferns. Hence, the present investigation entitled, “Studies on the effect of jeevamrit
application on frond production and longevity of Boston fern (Nephrolepis exaltata (L.) Schott)” 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 bothas drenchingand foliar spray and Trichodermaspp @ 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 (RBD) with 11 treatment combinations
replicated thrice. The results revealed that treatment T5 i.e. Jeevamrit @ 5% (Drench) + Foliar
application of Jeevamrit @ 10% recorded maximum frond length (43.21 cm at 150 DAP), length of
the longest frond (53.80 and 55.45 cm at 150 and 300 DAP, respectively), lamina length (39.41 cm at
150 DAP), plant spread (55.80 and 57.34 cm at 150 and 300 DAP, respectively), leaf area (171.41,
188.58 and 210.87 cm2at 30, 150 and 300 DAP, respectively), number of fronds per plant (27.73 and
45.64 at 150 and 300 DAP, respectively) and number of pinnae per frond (90.63 at 150 DAP).
Maximum frond width (4.00 cm at 30 DAP) was recorded with Jeevamrit @ 2.5% (Drench) + Foliar
application of Jeevamrit @ 10% application (T2) which was found to be at par with Jeevamrit @ 5%
(Drench) + Foliar application of Jeevamrit @ 10% (T5). Maximum number of frond yield per square
metre (110.92 and 182.55 at 150 and 300 DAP, respectively), weight of individual frond (3.20 g) and
vase life (15.33 days) were also registered in treatmentT5.
